GROUND WATER INFORMATION GUNTUR DISTRICT, ANDHRA PRADESH
1.0 INTRODUCTION
The Guntur district has been gifted with the vast surface and ground water
resources. About 3.56 lakh ha area is irrigated by canals and it has a ground water
recourses of 3.63 lakh ham. However the failure of rainfall over successive years
since 2001 has resulted in depletion in ground water resources as well as canal water
supply for irrigation. This has greatly effected the agricultural production. The supply
of spurious seeds, insecticides and fertilizers has further contributed to the failure of
the crops. It is reported that around 60 farmer belonging to 29 mandals have
committed suicides because of great loses they have incurred in farming over the
consecutive years. It is reported that majority of the effected farmers are those who
were engaged in cash crops like chili, cotton and tobacco forming. The list of the
farmers who have committed suicide in the district is appended at Annexure-I.
The Guntur district with a geographical area of 11,328 sq. kms falling
between Latitudes 15o44’ & 16o47’ North. And Longitudes 79o10’ & 80o55’ East
(Fig.-1) and having a population of 44,65,144 (2001 census) ( 22.50 lakh males and
22.15 lakh females) is one of the Central coastal districts of Andhra Pradesh. It
comprises 57 mandals under administrative control of 3 divisions namely
Narasaraopet, Guntur and Tenali. The district has 729 villages and 1036 hamlets. The
annual normal rainfall received by the district is 889.1 mm. Southwest and northeast
monsoon contributes 59% and 26% respectively. Mainly Krishan and Gundlakamma
rivers with its important tributaries drain the district. Its important tributaries include
Gundlavagu near Durgi, the Golivagu near Rentachintala, the Dandi vagu near
Gurajala, the Naguleru near Korampudi, the Gadidela vagu near Piduguralla, the
Edduvagu near Kovuru and both the Vite Vagu and Mada vagu near Amaravati
(Vaikuntapuram).

The district has 2 major and 1 medium irrigation projects. The Nagarjunasagar
Right Bank Canal Command (NSRCCA), Krishna Western Delta (KWD) Canal
System and Guntur Channels Scheme.
The NSRCCA has been designed of discharging capacity of 22,000 Cusec
through its two main canals with each one having a capacity of 11,000 Cusec. This
project has a vast network of irrigation system spread over 5 districts. The length of
the Right Main Canal is 201.6 km with an ayacut of 4.505 lakh ha. The length of the
Left Main Canal is 177.6 km with an ayacut of 3.869 lakh ha. The total length of the
Branch canals and Distributories is around 24,000 km. In Guntur district total
irrigation potential created is around 2,74,000 ha.
The Krishna Western Delta canal system (KWDS) covers 24 mandals. It has a
main canal length of 355.44 Km in total and 1,135 Km of branch canals. The head
discharge at Sithanagaram Head sluice is 8000 C/S. The total registered Ayacut in
Guntur district is 4,99,231 acres (2,02,038.78 ha).
The Guntur channel scheme is a Medium Irrigation Project for supply of water
for Irrigation of the high level lands adjoining Krishna delta. The requirement of
water for this project is drawn through Undavali vagu, which receives water from
Krishna River, through an out fall sluice, on the upstream of Prakasam barrage. The
head regulator is designed to pass the full discharge of 600 cusecs. The length of
Guntur channel is 47.00 km with total ayacut of 27000 acres (10927 ha). The project
wise irrigation details are given in Table-1.

Total 3,56,328
The total area irrigated by all sources in the district is 4,30,806 ha which
works out to be 23.33% of the total area of the district. Out of this about 3,56,328 ha
(82.71%) is irrigated through canal network and 1.94% through lift irrigation. 14%
area is irrigated through Tube wells and filter points and the rest 1.35% area is
irrigated through Tanks and other sources. The major crops grown are paddy,
coconut, groundnut, sugarcane, pulses, chilies, tobacco, cotton and fruit crops like
Banana, Orange, Mango and other fruit varieties.
About 40% of the district is underlain by hard rocks. About 35% area is
occupied by alluvium and the rest 25% by soft rocks.
The geological mapping of the district was first carried out by William King
and Bruce foote of Geological Survey of India (GSI). Subsequently detailed
geological mapping was done by various officers of the Geological Survey of India
during different field seasons. However CGWB has been carrying out different
scientific studies in the district soon after its formation. Under Hydrogeological
studies CGWB has covered the entire district under systematic hydrogeological
investigations/studies by the year 1990 in addition to other surveys. After this,
reappraisal surveys are being conducted in the district regularly. Recently it has also
conducted detailed micro level studies in the coastal mandals to map out the saline
and fresh water interface.
5
Under its Ground Water Exploratory program CGWB has drilled several
exploratory bore wells in the deltaic, coastal and other alluvial areas with a depth
ranging between 200 to 600 m. Right now under its regular program CGWB is
carrying out Ground Water exploration in hard rock areas of the district.
CGWB also monitors ground water regime through battery of wells
located throughout the district 4 times every year to ascertain the changes occurring in
the ground water regime due to failure of rainfall, development of ground water,
water logging areas and over exploitation etc. Each year water samples are collected
from these wells for chemical analysis to ascertain the changes in ground water
chemical quality. There are right now 39 National Hydrograph Network Stations in
the district.
In addition to the above CGWB has conducted Water Supply
Investigations, Geophysical surveys, Remote Sensing Studies, Ground Water
Pollution studies and Urban Hydrogeology etc. in the district.
2.0 RAINFALL
The district has one Indian Meteorological Observatory (IMD) at
Rentachintala, and there are over 40 rain gauge stations in the district. The mandal-
wise annual rainfall since 1997-98 to 2004-05 is given in Table-2 and the distribution
of normal rainfall over the district depicted in Fig.2. Isohyets showing the normal
annual rainfall as well as the rainfall for the year 2004-‘05 is depicted in Fig. 3. The
normal rainfall received in the district is 815 mm. The rainfall gradually increases
from western part to the eastern part of the district and towards the seacoast in the
order of 650 mm to 950 mm. Major portion of the rainfall in the district is received
during the south west monsoon between June and September, which contributes about
69% (562 mm) of the annual rainfall and 30% (244 mm) is received during the
northeast monsoon (October to December) and summer period. The distribution of
normal rainfall over the district during South-West and North-East monsoon are given
in Fig-4. The graphical representation of the district average annual rainfall since
1981 to 2005 is given in Fig-5 and the season wise distribution of normal rainfall is
depicted in pie diagram at Fig. 6. The rainfall plotting of few of the raingauge stations
at Pedakurapadu, Macherla, Gurazala, Piduguralla Fig.7, 8, 9 & 10 respectively
indicates that there has been progressively deficit rainfall over the years since year
6
2000 onwards. The declining trend ie deficit in the rainfall received in the district
over successive years has caused near drought conditions in the areas which does not
fall in canal commands.
The failure of monsoon rainfall over successive years since 2001 onwards has
led to failure of crops in the areas where farmers are dependent on the rains as well as
in the tail end of the command system. Successive crops failure due to deficit rainfall,

3.0 GROUND WATER SCENARIO
3.1 Hydrogeology:
The Guntur district is underlain by various rock types of different age groups
ranging from Archaean to Recent. The Archaean basement complex comprising
the granite-gneisses, Schists, Khondalites, Charnockites and basic dykes of
dolerites form the predominant rock types. It occupies around 1/3rd part of the
district mainly in the central part of the district. These are the predominant water
bearing formations in the district. These formations lack primary porosity. They
developed secondary porosity through fracturing and subsequent weathering over

ages and become water bearing, although very much limited. The movement of
ground water is controlled by the degree of interconnections of the secondary
pores and voids. The depth of weathered mantle ranges from about 8 to 15m bgl
and below this zone fractured rocks are known to occur down to 40.0 m bgl. The
depth to water level ranges from less than a meter to 12 m bgl. Dug wells
generally yield 10 to 80 or even up to 200 m3/day, depending on the location of
the well. Bore wells drilled in these formations are 30 to 40m deep and generally
yield 1.5 to 5 lps and sometimes even more depending upon the fractured zone
encountered in the bore well. The dug wells sustain four to six hours of pumping
and capable of irrigating about 0.8 to 3.0 hectares. A perennial spring, with a
discharge of about 200 lpm is located along a fault, near Bugga Melleswara
temple of Papayapalem in the Bellamkonda Mandal, and it is reported that this
spring is being used to irrigate 10 hectares.
The fringe of the Archaeans in the central part of the district is represented by
the northeastern part of the Cuddapah basin, namely Nallamalai group of Upper
Cuddapahs. In a sequential order, the younger Kurnools occurring in the
Cuddapahs and those in the western parts of the district are thrust over by the
Cuddapahs and these in turn by the Archaean granite-gneisses. The Upper
Gondwana group of sandstones and shales out crop are seen at places between
Guntur and Tenali. The youngest rock types of the district appear to be of Mio-
Pliocene age followed by the Alluvial deposits of Recent to Sub-Recent age. In
the Cuddapah and Karnool group of rock slaty phyllites, quartzites and lime
stones the ground water occurs in the joints, bedding planes and the weathered
portions. However, the quartzite do not form good aquifers in the area because of
their compactness and occurrence at high relief. The ground water is developed in
16
slaty phyllites by dug, dug-cum bore wells and few bore wells. The general
depth of wells varies from 3 to 25 m bgl, with moderate to very poor yields
ranging between 10 to 70 m3/day. The depth to water levels range from 0.4 to over
7.0 m bgl, but in phyllites and slates it varies from 4 to 15 m bgl. The general
yield of wells ranges from 20 to 80 m3/day, with exceptions in the highly fractured
locations.
The rocks of Upper Gondwanas occur as isolated out crops in the eastern part
of the district, viz., around Mutkuru, Sangam, Jagarlamudi and Kolkalur areas.
The Gondwana formations are of fluviatile or lacustrine origin and also contain
intercalated marine sediments, suggesting the marine transgression. The upper
Gondwanas in the district are divided into three divisions, viz., the basal
Budavada sandstones, which are buff coloured and of marine origin; the middle
thin bedded, buff coloured and fossiliferous (plant) Vemavaram shales and the
upper brown to red coloured and un-fossiliferous Pavaluru sandstones. The
ground water occurs under water table and confined conditions. The shales over-
lying the sandstone act as the confining medium. The ground water is tapped by
means of dug wells, dug-cum-bore wells and bore wells. The depth to water
ranges from 2.20 to 10.60 m bgl and the depth of dug wells varies between 5.50
and 18.50 m bgl. The tube wells in the area range in depth from 40.0 to 75.0 m
bgl, with yield ranges from 28 to 1300 lpm for drawdowns of 8.0 to 15.0m. The
quality of ground water in these formations at places is found to be brackish other
wise in general it is good for potable purposes.
The alluvial formations which are of recent to sub-recent in age were formed
from the weathering of the older rocks and also as fluvial/Marine alluvial
materials and residual soils. The fluvial alluvial deposits in the district are mainly
restricted to the Krishna river and its stream courses. Extensive tracts of alluvium
can be observed in the east and southeastern parts of the district and comprises of
intercalation of clay, silt, sand, gravel, pebbles and Kankar of variable thicknesses.
The thickness of alluvium varies from a few metres to over 100m. These are of
deltaic origin and marked at places by shallow to about 30m thick sandy to
gravelliferous palaeo/buried channels. The beach sands are combined to the areas
along the sea coast with the occurrence of beach ridges and back swamps.
Laterite, lateritic shingle and gravel occur in many parts of the district as
17
superficial deposits. The thickness of the alluvium along the stream courses vary
from 2 to over 10.0m bgl. Ground water is being developed in the flood plain
areas of Krishna river course mostly through filter-point wells and shallow bore
wells with yields ranging from 3 to over 15 lps as observed around Rayapudi and
Borepalem areas of Amaravati and Thullur mandals. The depth to water level in
the alluvium of fluviatile origin ranges from almost ground level to 5m bgl. The
wells located in the river terraces and alluvial ridges register deep water level
conditions of 7.0 to over 12.0 m bgl with poor to moderate discharges. The
extensive deltaic alluvium occurring along the eastern and southeastern parts of
the district comprises alluvium of over 100 m in thickness but due to their sandy
clay nature are poorly permeable and the ground water movement is rather
sluggish. As a result the ground water is highly mineralized and at places it is
found to be brackish. The ground water utilization for irrigation in these areas is
observed to be negligible due to poor quality. The palaeo-channels, buried
channels and flood plains occurring in this region, especially, in the mandals of
Dugirala, Tenali, Ponnur and Repalle, are found to be potential aquifers with good
quality water. The palaeo/buried channels at places are thin to about 30m thick
and consist of sandy, gravelliferous formations and yield fresh water. The extent
of these formations vary from a few meters to as much as 2.5 km in width and
hundreds of meters to several kilometers in length. Filter-point wells and shallow
tube wells are the common ground water abstraction structures in these areas.
Ground water is brackish to saline at shallow depths especially in the areas
bordering the coast. Only the beach ridges at shallow depths yield fresh water. In
the deltaic and coastal alluvial areas, the depth to water level ranges from less than
1m to 5 m bgl. The depth of open wells ranges from 2m to 12 m bgl and the depth
of shallow tube wells and filter point wells range from 10m to 27m, with yields of
25 to over 75 cu.m/hr. Hydrogeomorphology and Hydrogeology of the district are
depicted in Fig. 11. & 12. respectively.
3.1.1 Ground Water Regime Studies:
In order to monitor the ground water regime in space and time, the Central
Ground Water Board (CGWB) has been conducting Ground Water Regime Studies
by the establishing and monitoring National Hydrograph Network Stations (NHNS)
18
Fig. 11
19

20
in the entire district. The Board so far had established 39 such hydrograph stations in
various hydrogeological environments of the district which are being monitored four
times in a year ie. in the months of January, May, August and November. These
studies throw light on the pace of ground water development vis-a-vis recharge in
different areas and the variation in the quality of ground water with time. The
comparative study of the historical water levels highlight the areas extent of water
logging, ground water behaviour and stage of development, over exploitation if any
and fluctuations of water levels and quality changes with time and in space, effects of
surface water on ground water, rainfall (Pre-and post-monsoon) recharge, chemical
and other anthropogenic activities on the ground water regime. While analyzing the
ground water regime in the district the data of 220 observation wells monitored by
Andhra Pradesh State Ground water Department is also utilized. The State
department collects water levels every month and water samples twice in a year to
monitor the quality variations. The study of hydrographs of National Hydrograph
Network Stations indicate the changes in the ground water scenario of each station
from time to time. The data of all the observation wells when correlated with rainfall
as well as with the release and stoppage periods of canal water, there appears to be a
clear relationship. There is a perceptible rise in the water levels from June/July
onwards till December every year. Then the water levels fall from December
onwards till May. Just after the onset of monsoon (say June) to March of the
following year there is due to release of canal water in different irrigation commands
in the district and between middle of March to May/June, the canal water is stopped.
This is reflected in the hydrographs with a steep rise and decline. The fall in the
levels of hydrographs of the district may be attributed to the cessation of canal waters,
apart from the lessening effects of rainfall. Based on the hydrograph data,
hydrographs have been generated for the period since 1978 onwards and the same are
given in Fig.13 a, b, c, d, e, f, g, & h. On perusal of the hydrographs it is observed
that even though the annual rainfall received by the district for the last 4 years have
been below normal it is observed that out of the 39 hydrographs 9 show raising trends
during pre monsoon as well as during post monsoon periods. This may be attributed
to the application of canal water in the area where these wells are located however the
wells located near Guntur such as Prattipadu, Chebrolu, Sekuru and Guntur itself
indicate that the ground water is no longer being extensively used. On analysis of the
chemical data of water samples of these wells it is inferred that the ground water

around these wells have become saline due to saline water ingress. The hydrographs
of the wells at Repalle, Ponnuru, Chikaluripet, Medikondur show long term horizontal
trends of the permonsoon as well as for post monsoon periods this may be attributed
to the availability for surface water through canal and streams in the area and the less
dependency on ground water resources due its slightly saline in nature with Ec
reaching to 1200 micro- seimens/cm. The hydrographs of the wells located at
Rentachintala, Macheri, Sirigiripadu, Nekarikallu, Mangalagiri, Ipur, Vadlamudi,
Pondugula show falling trends both for pre-monsoon as well as for post monsoon
periods. This is because of the failure of rainfall over a period of time, more
dependency on ground water in this area due to non availability of the surface water in
the vicinity. Over all the picture of ground water indicates that the district average
shows a ground water raising trends.
3.1.2 Depth to Water And Its Behaviour In The District:
Taking the large extent of canal command areas as well as the resulting ground
water build up in the district, the depth to water level zones were demarcated in
the following order. The depth to water level distribution maps prepared for
November,’03 (Post monsoon) and May, 03 (Pre-monsoon) were shown in Fig. 14
& 15 and in the prevailing conditions in the district. On perusal of the two maps
indicates logging conditions during pre-monsoon period in a small area located in
the south-central part of the district i.e. in the area located just north of Bapatla.
But during Post-monsoon period, water logging conditions were observed in areas
around Atchempet, Nekarikallu, Pallapatla, Varagami, Chebrolu and Coastal
areas. About 75% of the area in the district especially in the central and coastal
areas show water logged (less than 2.0m bgl) to near water logged conditions
(DTW 2.0 to 5.0 m bgl) during post-monsoon period. But most of these areas are
occupied by areas prone to water logging (i.e. DTW 2 m to 5.0m bgl) during pre-
monsoon time accompanied by the stoppage of canal water. The upland areas,
pediment areas especially occupied by the quartzites, phyllites and slates and
alluvial ridges, areas along the Krishna river, registered deep water levels of over
10 m bgl. An appraisal of the depth to water level maps reveals that water levels
are shallow towards the branch canals and distributaries of NSRCCA,
30

32
KWD canal system and Guntur channel scheme and in certain parts, water
logged areas seem to be encroaching the areas prone to water logging and so
on. Temporary water logging conditions are also seen to prevail at certain
sections because of high rainfall, sudden release of canal water etc.
3.1.3 Ground Water Elevation And Flow Conditions In The District:
A study of the water table map of the Guntur district (Fig. 12) indicates that
elevation of water table in the district varies from less than a meter above mean
sea level (a msl) along the coast to 200m a msl in the central parts to above 200m
a msl towards the western and upland areas (around Veldurti) of the district. The
hilly areas in the district record high relief of more than 500m a msl. The water
table contours upto 20m a msl are widely spaced and occur along the eastern
alluvial areas as well as the central parts of the district, viz; around Narsaraopet,
Muppalla, lpur and achepalli. The water table contours become more compressed
towards Phirangipuram, Edlapadu, Nadendla and Durgi. Mounds of high
elevation of over 200m a msl were noticed in parts of Veldurthi. The water table
contours run more or less parallel courses and slope along the river and stream
courses, such as Krishna, Gundlakamma and Edduvagu. The hydraulic gradient
varies from less than 0.5m/km towards coast, to 2.5 m/km in the central parts, and
about 20m/km in the western parts (around Veldurthi).
3.1.4 Water Level Fluctuation:
Based on the water level data of National Hydrograph Network Stations, a water
table fluctuation map has been prepared (Fig. 16). On perusal of the map it is
inferred that barring few areas around Mangalgiri and Rentachintala, the entire
district shows a general annual fall of 0 to 3.0m during the pre-monsoon, 2003
which can be attributed to the stoppage of canal water in addition to the pre-
monsoon ground water withdrawal. This process is entirely reversed with the on
set of monsoon and supply of canal water, as revealed by the rise in water table
33
Fig. 16
34
upto 2.0m. The rise and fall is recurring and within 0 to 2.0 meter in the areas near to
the Nagarjunasagar Right Canal and its branch canals, contrary to the sharp and
extreme rise and fall observed in the tail end areas of Nagarjunasagar Right Canal
Command Area.
3.1.5 Study of Long Term Water Level Trends In The District:
To assess the long-term trends of water levels in the district, the National
Hydrograph Network Stations data for 20 years (1984-2003) period were analyzed
and the results show a declining trend from 0 to 1.0m during post-monsoon period
and the rising trend from 0 to 2.0 m during pre-monsoon period in the larger parts
of the canal command areas of the district. The trend are just opposite for the tail
end areas during these periods.
3.2 Ground Water Resources:
The ground water potential in the Guntur district, as on March, 2004 is
estimated as per the GEC-1997 and the Report has been published by State
Ground water board in consultation with Central Ground Water Board. The
mandal wise ground water resources of Guntur district are given in Table-3.
3.2.1 Ground Water Recharge:
The sources of recharge to the ground water body in the district are rainfall,
seepage from canals, return seepage from surface water irrigation, seepage from
tanks/lakes/ponds and negligible portion through influent seepage. The trend of
rainfall departure curve indicates the consistent nature of recharge in recent years.
Analysis of National Hydrograph Network Stations and the observation wells of
Andhra Pradesh State Groundwater Department data and hydrographs indicate the
rainfall infiltration factor of 0.12. Applying the rainfall infiltration factor, specific
yield and seepage factors to the area suitable for ground water recharge in the
district, the annual utilizable ground water recharge in the district is estimated to
be 3633.88 MCM/year.
Leaving the flood plain and palaeo-channel areas, the ground water utilization in
the large parts of the district is very limited because of the intensive canal.

irrigation, especially by the Nagarjunasagar Right Canal Command Area (NSRCCA),
Krishna Western Delta (KWD) canal system and the Guntur Channel Scheme in these
areas. In the tail end areas of the canal system, upland areas, flood plain,
palaeo/buried channel areas, the ground water is being tapped both for domestic and
irrigation purposes. These areas include Veldurti, Bollapalli, Chilakaluripeta, Krosur,
Atchampet, Amaravati, Tadepalli, Mangalagiri, Thallur, Tadikonda, Dugirala,
Kollipara, Kollur, Bhattiprolu, Tenali, Vemuru, Amarthalur, Tsundur and Ponnur
mandals, where the ground water is developed through open wells, energized dug,
dug-cum-bore wells, shallow tube wells and filter-point wells On the basis of the
hydrogeological and other related information, the net annual recharge for the entire
district is estimated as 3633.88 MCM/year and the net annual ground water draft in
the district is worked to be as 365.42 MCM/year. Thus the ground water balance for
future utilization is 3268.47 MCM/year based on the balance potential available for
future development.
3.2.2 Stage of Development
In order to check over-exploitation of ground water and to utilize the available
resource in a planed way, the Ground Water Estimation Committee (GEC) 1997
has introduced certain norms so as to classify the areas as White, Grey and Dark
categories. The blocks or mandals, where the stage of ground water development,
in a period of five years, is below 65%, the area is categorized as ‘White’ or safe;
those falling in the range of 65 to 85% as Semi critical and those 85%-100%
‘Critical’ and above 100% over exploited . The present stage of ground water
development in the district is 10% with a net draft of 365.42 MCM out of the
Ground water resource of 3633.88 MCM/year. Taking the annual growth rate as
2%, the stage of ground water development after five years is projected as 14%
which comes under safe or ‘White’ category for further ground water
development. Similar computations were made to assess the ground water
potential and development prospects for each mandal and tabulated in Table and
are shown in Plate. A perusal of the table highlight that Bollapalli mandal as Semi
critical, with the present stage of development at 84%.
It is seen from the Table that the stage of ground water development is around
10% as most of the mandals are covered under surface water irrigation. The water
levels in most of these areas are shallow, i.e.., within 5.0 m bgl, with the
39
prevalence of water logged and near water logged conditions. In such areas,
ground water development through conjunctive use of surface and ground waters
would mitigate not only water logging conditions but also improve the quality of
ground water.
However, when resource is calculated at the village level it seen that about 46
villages are falling under semi-critical/critical/over exploited category. These
villages are listed in table- along with the level of development. It is seen that 13
villages are under semi-critical stage where as 8 villages are under critical stage
and the rest 25 are under over exploited stage of development (Table 4).

3.3 Ground Water Quality
The ground water in the district is generally fresh and potable. The ground
water temperature generally varies from 22°C to 28°C. The suitability of ground
water largely varies from area to area both for domestic and irrigation purposes.
In most of the areas, the ground water is devoid of carbonate. The range of
different chemical constituents in ground water of the district is given in table-5.

3.3.1 Quality of Water In Shallow Aquifers:
In the district, the hydrogen ion concentration (pH) varies from 7.67 to 8.53,
indicating the alkaline nature of ground water. Calcium together with magnesium
43
and carbonates impart the property of hardness to water. The concentration of
calcium and magnesium in ground water is with in the permissible limits for
domestic use. The sodium concentration is important in classifying the irrigation
water and in the district, its concentration when examined in the form of Sodium
Adsorption Ratio (SAR), most of the areas cover under irrigation water class fall
under medium to high Sodium Hazard category ie most of the irrigation water fall
between C3-S1 and C4-S3 class (Fig.-17) with Sodium Adsorption Ratio of less
than 25%, as per the irrigation water classification of Wilcox (1946) and Richards
(1954) (Fig.18).
In most areas of the district, carbonate is found to be absent in ground water.
The general concentration of bicarbonate varies from 200 to 400 ppm. Total
hardness expressed as calcium carbonate generally ranges from 215 to 300 ppm
and is within the desirable limit of Indian Standards Specifications (1991) for
drinking water and laundry purposes
Figure-17. Classification of Ground Water for Irrigation purposes by US-Salinity diagram

Figure-18
CLASSIFICATION OF GROUND WATER OF GUNTUR DISTRICT FOR IRRIGATION AS PER WILCOX DIAGRAM
3.3.1.1 Chloride in Ground Water:
Depending upon the concentration of chloride in ground water it is classified
under drinking water class as fresh when the concentration is low and as brackish
and saline when its concentration is very high. These classifications are depicted
in Fig.-19. Accordingly, the alluvial areas south of Guntur and the deltaic areas
in the district are brackish. In spite of its brackish nature, ground water with
chloride content of 500 to 1000 ppm is found to be potable. The rest of the areas
western and north western part of the district the ground water generally fall under
the potable to fresh water class with the chloride content with in 500 ppm.
4 WATER SAMPLES ARE BEYOND UNSUITABLE RANGE
Fig 19
3.3.1.2 Fluoride Distribution:
The Indian Standards Specification (1991) classified the permissible limit of
fluoride in water as 1.50 ppm. Except in certain areas in the district, the
distribution of fluoride is within the permissible limits of 1.50 ppm. Map showing
the distribution of the fluoride in ground water is presented as Fig.-20. In
Vinukonda & Krosuru mandals fluoride concentration is a little above the
permissible limits of 1.5 to 2.28 ppm.
3.3.1.3 Sulphate Distribution:
As per the drinking water standards of ISS (1991), the desirable limit sulphate in
ground water is 200 ppm and permissible limit is 400 ppm (but in the latter limit,
the magnesium should not exceed 30 ppm). Areas along the coast and in areas
underlain by deltaic alluvium, and areas around Rentachinthala and Gurajala,
contain sulphate concentration of 200 to 350 ppm. The sulphate distribution in
other parts of the district is within the desirable limits of drinking water standards.
3.3.1.4 Nitrate Distribution:
Based on the drinking water standards, the distribution of Nitrate in ground
water in the district is presented as Fig.-21. Nitrate concentration in the areas
around Mangalagiri, Moolpur, Nizampatnam, Prathipadu, Vinukonda, Pasipadu,
Krosur, Uttukuru, Amaravathi, Pirangipuram, Gurajala, Rentachintala and Guntur
is more than the permissible limits of 110 ppm, and far exceeding the limits
prescribed by various public health authorities, the results of which can be
detrimental to public health. In general, the distribution of nitrate concentration in
the district is above the desirable limits of 45 ppm. The high concentration of
nitrates in the district can be due to the application of nitrate fertilizers, dumping
of sewage and agricultural waste concentration of nitrate plumes, septic system
etc.

Specific Electrical Conductance:
The Specific Electrical Conductance (EC) of ground water in the district varies
widely from less than 480 to more than 5000 micro Siemens/cm at 25°C. Specific
conductance is a measure of dissolved solids in water. Based on the irrigation
water class standards (Wilcox, 1955), a map showing the distribution of Electrical
Conductance in ground water is prepared and presented as Fig.-22. The study
reveals that the entire district barring Northern, central and south eastern part
show specific conductance greater than the permissible limit of 2000 micro
Siemens/cm. This may be because of the brackish to saline nature with high TDS
(total dissolved solids) concentration in the shallow aquifers in these areas.
Ground Water Quality in Deeper Aquifers:
The hydrochemical analysis data of water samples collected by Central Ground
Water Board during the deep exploratory drilling upto maximum depths of 600m
in the Krishna Western Delta alluvial areas of the district indicates, the water to be
alkaline with pH ranging from 7.45 to 8.05. The specific conductance (EC) vary
from 4218 to 32,610 micro-Siemens/cm, but for the well at Musalipadu which has
recorded Electrical Conductance of 2202 micro-Siemens/cm, (i.e., close to the
permissible limit). The chloride values range from 100 to 2358 ppm. The
abnormal values of electrical Conductance and high concentration of chloride
indicate that the ground water from deeper aquifers is unsuitable both for domestic
ad irrigation purposes.
The chemical analysis of water samples collected during zone tests from some
of the boreholes drilled in Upper Gondwana sandstones by Central Ground Water
Board indicated that the water is fresh and potable with pH of 8.10 to 8.14,
Electrical Conductance of 886 to 1406 micro Siemens/cm, chloride of 90.4 to
339.5 ppm, fluoride values of 1.15 to 1.30 ppm and total hardness of 43 to 290
ppm.

Most of the Guntur district is traversed by good network of irrigation canals of
the Nagarjunasagar Right Bank Canal Command Area (NSRCCA), Krishna Western
Delta (KWD) Canal System and Guntur Channels Scheme. Only the up land areas of
the district are not covered in any of the irrigation scheme. About 77.61% of the total
irrigated area in the district is through canal network and 2.94% through lift irrigation.
15.72% area is irrigated through Tubewells and filter points and the rest 3.72% area is
irrigated through Tanks and other sources. The area irrigated under different sources
in the district is given in Table-7 and the Mandal wise and source wise details of
irrigated area is given in Table-8. Wells and filter points irrigate 7.98% and the rest of
the area accounts for 3.72 % is irrigated by tanks and other sources. Source wise area
irrigated is depicted in pie diagram in Fig.23.

From the Irrigation pattern, in the last 10 years, it is seen that (Fig 24) there
has been a steady increase in area being brought under irrigation. However, since
1999 till 2002 the area under irrigation in the district remained same but during the
year 2001-02 & 2002-03 the area irrigated has fallen drastically i.e. by 1,24,512 ha.
amounting to 32% as compared to the year 2001-02. This is attributed to the failure in
rains in the district over two successive previous years. This can be seen in the Fig-25
& 26, wherein the surface sources for irrigation i.e. in Canals and Tanks are seems to
have fallen drastically. Due to the shortage of surface water for irrigation in Canals
and Tanks has forced the farmers to look for alternate sources for irrigation. As a
result of this, more and more areas was brought under ground water irrigation through
Tube wells/Bore wells/filter points and Dug wells. (Fig 27 & 28 ) Indicate that there
has been a steady increase the area being irrigated by tube wells/bore well/filter points
and dug wells over the same period.

The major KWD system and the medium Guntur channel Schems were
constructed to irrigate two lakh hecares of land in the district. And also the Nagarjun
Sagar Canal Command area (NSRCCA) of Nagarjunasagar Project is designed to
irrigate 4.75 lakh hectares in the Guntur and Prakasam districts under its right canal of
444 km. The Right Main Canal, also known as “Jawahar Canal” is a contour canal
designed to carry the maximum head discharge of 311.5 cu.m/sec. The entire
Nagarjunasagar Canal Command Area is divided into 22 blocks. Leaving the small
blocks from 1 to 3 where it is all wet, the Nagarjunsagar Canal Command Area was
localized for wet crops in one-third area and for irrigating dry (ID) crops in two-thirds
area, so that water could be provided to the maximum area. The share of
Nagarjunsagar Canal Command Area water for the Guntur district is about 57%,
covering from block 1 to the upper reaches of 15th block, with a registered ayacut of
2.72 lakh hectares. The irrigation details of Major, medium and Minor irrigation
schemes for the district are furnished in Table-1

4.0 Ground Water Management Strategy The timely supplies of required inputs result in targeted production and
productivity. The existing water distribution system in the canal command areas of
the district includes integrated and conjunctive use, warabandi system of irrigation,
diversion and lift irrigation schemes and localized system of irrigation, all these
schemes are intended to take water to the tail end and needy areas of the canal
commands. But these water management practices are being vaguely or poorly
followed in the district. In addition to these practices, the surface and ground water
resources in the district can be effectively used, taking the following aspects into
consideration.
(i) Surface water may be used over extensive areas with reduced number
of watering. Ground water may be supplemented in conjunction with
surface water for intensive irrigation to the extent possible.
(ii) Ground water may be used as a stopgap against the insufficient surface
water supplies.
(iii) To rejuvenate most of the wells abandoned after the release of canal
water.
(iv) To release canal water only for single crop and make the farmers
depend on ground water for second crop.
(v) In order to utilize saline ground water, canal water may be blended
with saline water in a suitable proportion to meet the crop water
requirements and protecting the soils.
(vi) Proper lining of the canals to reduce the seepage losses.
(vii) Provision of efficient surface and sub-surface drainage.
(viii) Pumping out excess water in the water logged areas to control rising
water levels and to facilitate drainage to augment canal supplies during
the period of shortages of surface water.
(ix) To educate farmers in the economical and conjunctive use of ground
water and canal water supplies. Financial help may be provided
wherever needed to the farmers.

4.1 Ground Water Development
Guntur has a privilege of having vast network of canals through two major and
one medium irrigation projects because of which the district has both surface and
ground water resources in abundance. In fact about 19.5% of the district receives
surface water, which meets 82.71% of irrigation needs of the district. To make use
of the ground water as a sustainable resource the approach to develop this valuable
resource needs scientific and judicious management system through proper
planning and design of wells of the area. The optimum design of wells depends
on the local hydrogeological conditions, cropping pattern and also the quantum of
water to be discharged. In the district dug wells and dug-cum-bore wells of
dimensions 3.0 to 6.0m dia and depth of 10-18m are feasible in the granite and
related rocks like. The unit cost of construction of a dug well will range between
Rs. 25,000 to Rs. 44,500/- depending upon the depth to which it is constructed.
And the unit cost of dug-cum-bore wells will cost between Rs. 31,000 to Rs.
39,400/-. In limestone, sandstone, alluvium and shaley formations. These wells
need masonry lining in the case of crystalline rocks or R.C.C. rings with weep
holes in alluvial, weathered (loose) material as a preventive measure against
caving or collapsing. The dug-cum-bore wells are feasible in granites, limestones,
phyllites, sandstones and shales depending on the availability of fractures and
weathered zones in the well. 100mm. bores down to 30m from the bottom of the
dug well portion of the wells are recommended. The unit cost of construction of
dug wells in limestone will cost around Rs.17,300 to Rs.32,500 depending on the
diameter of the borehole. The DCB in limestones will cost around Rs.23,300/-.
Bore wells down to 100 to 150m. depth are feasible in crystallines, shale,
limestone and quartzite formations with 15 to 20m depth casing against weathered
mantle to prevent caving or collapsing in the hard rock areas of the district. The
unit cost of construction of bore wells in crystalline is around Rs.12,500 to
Rs.20,600will be around for bore well of 150 mm dia with a depth range between
40 to 80 mt. Tube wells of 254 mm & 380mm. diameter down to a depth of
about 100m to 120 m tapping 30 to 40m saturated aquifer material in sandstone
formations are feasible whereas in alluvial areas where the thickness of saturated
62
zone exceeds 5m filter point wells of 254mm. diameter down to a depth of 15 to
20 m depth are feasible.
In the case of irrigation wells the spacing norm between 2 wells in an area is not
properly adhered to as a result it would lead to mutual interference between two
adjacent wells. Liberal institutional financing has accelerated the growth of
ground water development and accordingly the spacing norms have been
mandatory by Government of India in the institutional financing, so that wells are
economically viable. Based on the pumping tests a well for a 6 to 12 hrs. duration
of pumping, the transmissivity, storativity and radius of influence estimated from
the pumping tests, the spacing should be such that the pumpage works out to be
economically and in turn does not interfere with other near by irrigation pumping
well. Required spacing between two wells is given in Table 9.
Table-9: Spacing to be maintained between any two wells

30-90 100 200-300
Non-perennial streams within 100m
0-150 160 300-500
In the coastal areas caution also should be exercised to avoid construction of
wells within in 1 km. from coastline to prevent ingression of seawater. Because
the zones adjacent to the coast extending 200 – 500m. from the shore line towards
land ward is found to be extremely sensitive to the fluctuations of the water table
and needs judicious ground water withdrawal. As per the norms prescribed in the
National Water Policy of India (1987) ground water development in the coastal
zone has to be done cautiously taking spacing norms into account especially
during summer months. This may be accomplished by the use of low capacity
pumping to prevent the possibility of salt-water intrusion into fresh water zones of
the area from sea front.

4.1.1 Drinking water supply schemes:
Ground water forms the main source for drinking water supply schemes in non
ayacut areas of the district. The protected water supply schemes are maintained
by Rural Water Supply department under Panchayat Raj Department of
Government of Andhra Pradesh. These schemes include river lift, surface flowlift
schemes. Bore wells, large diameter dug wells, dug-cum-bore wells and hand
pump fitted shallow bore wells.
There are a total of 512 protected water supply schemes and 4868 bore wells,
1540 open wells and 182 other wells for drinking water supply. The mandal wise
details of water supply status are given in table-10.
Around 166 villages are having fluoride problem in ground water and about 3
villages are having brackish ground water. There are in total 68 problematic
villages so far as drinking water is concerned in 9 mandals. During 2003-04 state
government has spend Rs. 41.43 crores for providing drinking water to these 68
villages. The mandal wise details are given in table-11. Table-10

3.4.2 Irrigation by ground water source:
Ground water is the most dependent source for the irrigation. The utilization of
ground water for agriculture is practiced by ground water abstraction structures such
as dug wells, dug-cum-bore wells and bore wells. The net area irrigated by ground
water in the district during the last 7 years is given below. (In Ha.)
1997-98 1998-99 1999-2k 2000-01 2001-02 2002-03 2003-04 44317 46274 51676 50893 50027 47764 60562
Out of the total area irrigated 222671 ha ground water irrigation accounts for 27% in
the district.
3.4.3 Ground Water Management and Conservation:
Besides the proper development of ground water potential in the district, stress
should be laid on its management and conservation. As such, groundwater
augmentation through rain water harvesting can be explored. The Western and
Southwestern part of the district covering Veldurti, Durgi, and parts of Karempudi,
Nakarikallu, Ipur and Bollapalli mandals are feasible for rain water harvesting.
67
These, areas fall under non-command area and ground water is found to be at deeper
levels. In these areas the excess rainfall run off should be brought in to use to augment
ground water recharge. The type of structures feasible in the area are contour trenches,
rock fill dams, check dams and conversion of tanks in to percolation tanks.
5.0 RECOMMENDATIONS 1. The tail-end areas of canals and upland areas in the district are facing chronic
water shortage problems, where the phyllites or granite gneisses form the
principal aquifers. The thick weathered mantle and deeply weathered and
fractured zones occurring along certain lineaments, its intersections and buried
pediments, may be tapped through proper ground water structures to draw
copious supplies of ground water in these areas.
2. Conjunctive use of surface water and ground water should be followed not only
to meet the requirements of tail-end areas but also to reduce the water logging
and salinity problems. The exploratory drilling programmes in the selected
places of canal commands will enlighten the conjunctive utilization of surface
and ground water. In these areas ground water loss will reduce the water
logging conditions and more areas may be brought under agriculture.
3. The present status of over development of ground water 25 villages is more than
100% falling under over exploited category. 13 villages are falling under semi
critical category where as 8 villages are under critical category. In these villages
proper measures are to be taken to
• To stop further development of ground water.
• Surface water may be brought in to use in the area.
• Artificial recharge methods needed to be adopted for
augmentation of ground water.
• Farming of wet crops like paddy should be discouraged. And
farmers should be encouraged to cultivate more and more less
water requirement crops.
4. Proper measures have to be taken in the sitting and selecting the ground water
abstraction structures, in the implementation of water management practices
and to check the aerial distribution of salinity. The ground water development
in the district can be taken up as per the perspective plan described in the
report.
5. Studies are to be taken up to check the recurrence of fluorosis, especially in
the Vinukonda, Krosuru areas, and remedial measures have to be
implemented. In a fluoride endemic area, it is not necessary that every water
sources is contaminated. The good sources may be identified by
hydrogeologists, and the people can be educated to consume water supply only
from such sources.
