CHAPTER - VII
STUDIES ON WATER QUALITY OF PAlMBA RIVER
1.0 INTRODUCTION
Rivers have always been the lifelines of development and with the
course of time have borne the impacts of development and industrialization
in the form of abstractions of water besides other wastewater releases.
Industrial and domestic discharges produce diverse impacts on the quality
of the receiving body of water. Even though the flowing water bodies, or
lotic systems, have the capacity to recharge and self-cleanse themselves in a
given time, they rarely can do as fast as they are being used or polluted.
Water quality deterioration is imminent, of course, in such riverine systems.
Water quality management strategies to arrest the degradation of
aquatic systems include a combination of technological, social and financial
aspects. Mathematical modeling forms an integral part of the process for
predicting future conditions under various loading scenarios or management
action alternatives (Schooner, 1996). The latter enables selection of a
feasible treatment option to maintain the water quality.
1.1 ' River water quality modelling
Water quality models take recourse to the behavioural
characteristics of receiving bodies of water such as channel and flow
characteristics, which influence the mixing processes and dispersion of
waste into surface waters. The three types of mixing processes themselves,
viz, vertical, transverse and longitudinal, govern the extent of stratification,
the rate at which pollution spreads from one bank to the o w , and the
movement of wastewater in the downstream, respectively. The thermal and
hydraulic conditions of the river have a significant influence on both the
biochemical and chemical processes (Gandolfi et al, 1996).
Models for river water quality that are based on the one or two-
dimensional mass transport equation, are widely used to determine the
extent of pollution in rivers which are not very wide or deep. These models
consist of a set of dynamic equations governing the evolution of the
relevant hydrologic, thermal and biochemical phenomena. The equations
are all based on the conservation principles of mass, momentum and
energy, regardless of which phenomena is considered.
To assess the Impact of discharges on river water quality, the
widely used comprehensive and versatile stream water quality simulation
model QUAL 2E (Brown and Barnwell, 1987) devised by the US
Environmental Protection Agency has been employed. QUAL 2E is a
modeling program applicable to all dendritic streams that are well mixed. It
assumes that the major transport mechanisms, advection and dispersion are
significant only along the main direction of flow (longitudinal axis of the
river). The model can be operated either as a steady state or as a dynamic
one. In contrast to dynamic models, steady state models provide predictions
for only a single set of environmental conditions and can be applied for
critical or worst case conditions, that represent extremely .low assimilative
capacity (David and James, 2000). The basic equation solved by QUAL 2E
is the dimensional advection-dispersion mass transport equation, which is
numerically integrated over space and time for each water quality
constituent. For any constituent C, the equation may be written as:
6M/6t = 6 [A, DL(6C/6x )I 6x.dx-6 ( A,uC)/Gx.dx+ ( A, dx) dC/dt+ S
Where, M-mass ( M), x-distance ( L), t- time ( T), C-concentration
( ML-'), A,- cross section area ( L* ), DL- dispersion coefficient ( L~ TI), U-
mean velocity ( LT'), S-external sources or sinks ( MT -I).
Field data required to reproduce the hydrodynamic and water
quality aspects of a river by means of the mathematical model QUAL 2E
include the following:
rn Flow measurement and characterization
Hydraulics of the river
Cross section profiles of the main river and its branches
Point sources- their flows and characteristics
Water quality management is not simply the elimination of wastes
or technological removal of wastes, but economics and prevailing political
situation also need to be recognized as facts of life when dealing with the
problems of pollution control (Thomann, 1974). The approach should be
such that the problem of pollution control is placed in a frame work that
allows for mekingful decision making, depending on the appropriate
mathematical model that could be used to attain the desired quality of
water.
The reduction in the quantity of water in rivers can result in the
decrease of flow and in turn will affect the quality of water due to
diminishing levels of flushing within the system (de Mars and Ganitsen,
1997). Wherever there is the additional abstraction, water quality problem
has gained more attention (Chessman and Robinson 1987; Welsh and
Stewart, 1989; Barors et a1 1995; Muchrnore and Dziegielewiski, 1983)
A study on the influence of physico-chemical variables on the
quality of Thames estuary, London during drought condition (Martin and
Michael, 2000) has reported that most water quality parameters are
influenced by the freshwater flow. Reductions in freshwater flow towards
the estuary due to natural lowering of water levels in river and increased
abstraction, have a major influence on water quality of estuarine water
which could spread to many kilometers beyond the point of entry. QUAL
2E simulation analysis was successfblly validated for predicting the
concentrations of biochemical oxygen demand, dissolved oxygen, total
phosphorous and ammonia-nitrogen for the entire Kao-Ping River Basin,
Taiwan (Ning et al, 2000)
QUAL 2E was also applied for the modelling of one of the River
Kali in India(Kudesia,l998) The results indicated that, better the input data
base, stronger would be the accuracy of prediction.
The Enhanced Stream Water quality Model QUAL 2E permits
simulation of several water quality constituents in a branching stream
system using a finite difference solution to the one dimensional advective-
dispersive mass transport and reaction equation.
In a QUAL 2E Model, the main stream is divided into many sub
reaches or computational elements equivalent to finite differences. The
model is formulated based on flow (Q) for the hydrology balance,
temperature (T) for heat balance and concentration(C) for material balance,
which include both advective and dispersive transport. National Council of
the Paper Industry for Air and Stream Improvement (NCASI), India and US
Geological Survey tested the revised program of QUAL 2E on several
intensively sampled rivers across the United States. The model was applied
in many European countries, England, Greece, Belgium and Spain and also
widely used in South America, Korea and China.
In QUAL 2E Model, a particular stream is divided into a network
of "Head Waters", "Reaches" and "Junctions". QUAL 2E assumes that 26
physical, chemical and biological properties are constant along a particular
"Reach". The QUAL 2E computer program includes the major interactions
of the nutrient cycles, algal production, benthic carbonaceous oxygen
demand, atmospheric re-aeration and their effect on the dissolved oxygen
balance. In addition, the program includes a heat balance for the
computation of temperature and mass balance for conservative minerals,
coliform bacteria and non-conservative constituents such as radioactive I
substances (NCPI, 1985)
In this study QUAL 2E Model was used to find out the discharge
required to dilute the colifom generated in the Pamba river during a
pilgrimage season.
2.0 HYDROGEOLOGICAL DETAILS OF PAMBA RIVER
Pamba river (Fig. 41 and 42) the third largest river in Kerala,
originates from the Pandalarn Hills, the second segment of the forest in the
southern Western Ghats, adjacent to the north of Agasthyamalai range. The
main tributary Kakki river join with the Pamba river in the highlands, the
river Manimala join with it in the plains. After meandering through
Pathanamthitta, Idukki and Alleppey districts in Kerala, over 176 km, the
river ultimately falls into the Vembanad lake. The Sabarigiri Hydro-
Electric project, the second major hydel scheme in Kerala is situated on this
river. The famous forest Shrine of Swami Ayyappa (Sabarimala Pilgrim
Centre) is situated amidst the north western foot hills of Pamba plateau and
the mount plateau.
Many streams originating from the hills flow through Sabarimala
and join together to form Njunangar. Marakkoottam, Sabaripeedom,
Appachimedu, Chelikkuzhi and Cheriyanavattom flow into the Njunangar
before it merges with the river Pamba about 50 m downstream of
Arattukadavu near the Pamba temple. Over the years, the Sabarimala has
become one of the most popular pilgrim centres in South India and it is
estimated that around 50 million people visit Sabarimala, during October to
January every year. The pilgrims use the Pamba river sides for responding to
nature3s call due to the lack of alternate facilities leading to contamination of
the river water. Also the sewage tank near the parking ground at Pamba is
always found leaking into the Pamba.
According to the Kerala Pollution Control Board (KPCB), though
there are about 46 sewage collection tanks at the Sannidhanam alone, it is
observed that the present facility is grossly inadequate to treat the sewage
generated during the peak days of the pilgrimage season. So the untreated
sewage finally reaches the river through Njunangar. Besides, waste water
from various hotels and restaurants also reaches Njunangar. A huge volume
of wastewater and solid wastes fiom the Devaswom mess and the Appam
and Aravana units directly flow into the Njunangar stream, leading to the
contamination of the Pamba river water.
River water pollution at Pamba- Triveni, the confluence of the
streams of Kakkiar and Kochupamba is a major environmental problem. In
this chapter, the water quality of river Pamba during the pilgrimage season
and the application of QUAL 2E Model to estimate the assimilative
capacity of the river are presented.
Fig. 42 A View of Pamba River
2.1 Methodology
A network of sampllng stations along the Pamba river especially
near the Sabarimala pilgrimage centre were selected for the water quality
study (Fig.43). Water samples from five stations were collected for
physico-chemical and bacteriological studies. Sampling and analysis were
done as per APHA (1998). The various water quality parameters analysed
for the samples included temperature, pH, EC, DO, BOD, chloride,
sulphate, total hardness, total alkalinity, nitrate, phosphate, sodium,
potassium, calcium, magnesium, iron, copper and coliforms.
Primary data on the water quality of Pamba river has been collected
from stations of Kochupamba, Kakkiar, Triveni, Nadappalam and
Ganapathi temple. These stations are very close to the Sabarimala
Pilgrimage centre, which is one of the important places in the river basin.
Secondary data is collected from Kerala Pollution Control Board.
3.0 RESULTS AND DISCUSSION
Of all the 18 parameters analysed, the major water quality problem
of Pamba river is associated with bacteriological contamination and the
BOD fluctuation. The faecal coliform values ranged from 1100
MPNl100ml to 46000 MPN/lOOml. Kakkiar and Nadappalam are the
grossly polluted areas. Physico-chemical parameters like pH, temperature,
total dissolved solids, chlorides, nitrates, phosphates etc were observed to
be within the limits of Pollution Control Baard.
The major findings of the water quality status of river Pamba are
the following:
BOD fluctuation
The BOD value ranged from 0.90 mg/l to 4.53 mg/l and the
maximum value of 4.53mgA was obsenred at Kakkiar, Pamba upstream
during the month of December, 2000. BOD value is found to be within the
permissible limit at all other stations. According to Central Pollution
Control Board, BOD values for drinking and bathing water should not
exceed 3.0 mgll. The BOD values were high at Kakkair and Triveni during
the month of December. This is attributed to the increased demand of
oxygen for the degradation of the organic wastes dumped into the Pamba
river. This observation is in agreement with that of Singh and Singh
( 1995).
*:* Bacteriological contamination
All the samples from all the five stations were c~ntaminated with
coliform bacteria. The value ranged from 240 MPN/lOOml to 46000
MPN/100 rnl. The pollution in Pamba near Sabarimala is due to defecation
of the pilgrims besides bathing activities. The tanks overflow quite often
and hence pollute the river. In addition wastes are dumped in the river at
many locations through sewage collecting earthen tanks on the banks of
Pamba. The total coliform number per 100 rnl is reported to be from 4000
to b 0 0 0 MPN. The maximum permissible limit of coliform content in
river waters is 500MPNl100 ml according to Central Pollution Control
Board (Table.40).

3.1 Tolerance limit for various uses
As per BIS-IS 2296-1982, the tolerance limits of various
parameters had been specified based on the classified use of water. The
classification as given in table 1 has been adopted in India. River water
quality usage is classified as follows:-
Class A is the drinking water source without conventional
treatment, Class B allows water to be used for outdoor bathing, Class C for
drinking water with conventional treatment, Class D is fit for wildlife and
fisheries, and Class E means water is fit for recreation, horticulture,
irrigation and industrial cooling.
AS a water quality planning tool, the Enhanced Stream Water Quality
Model (QUAL 2E) which is a steady state model for conventional pollutants is
used for simulating the flow requirements needed for diluting coliform contents to
the desirable limit. The details of the model used and results are given below.
3.2 Water Quality Simulation of Pamba river
A 20 km stretch of Pamba river is segmented into 6 reaches each of
which is sub-divided into elements of equal length of 1.0 km. A layout of
Pamba river is given in Fig.43. Stream network with computational
elements and reaches is given in Fig.44. Only coliforms are generated since
the other parameters are not of much significance in the considered system.
Physico-chemical and bacteriological analyses were camed out and the
results are furnished in Tables 41-43. This data is utilized for applying
QUAL 2E model. Water samples collected from various stretches are tested
in-situ for dissolved oxygen. Velocity and cross section are measured for
calculating the river flow.

There are. no point loads in the form of drainagelsewer. The point
loads considered are points/elements where waste is accunt~lated and the
coliforms are generated within the system itself by the bathing of crowds of
pilgrims of Sabarimala (of the order of 50 million people during one season
starting from immediately after north-east monsoon and ending up
sometime near the middle of January). The six point loads considered in
this study are presented in Table 44. For running the model a flow of
0. lm3/sec is assumed for the point load. The colifom count is assumed as
zero for the headwaters of the initial stage. A plot between simulated
coliforms and discharge is furnished in Fig. 45 and the input and output
data of water quality modelling is presented in Table 45 and 46.

4.0 CONCLUSIONS
*:* To bring down the observed coliform count (46000 MPN/100 ml) to the
maximum permissible level of 500MPN/100ml (central Pollution
Control Board) the discharge in the main stream has to be increased
from an observed value of about 4 m3/sec to the order of about 35
m3/sec. This is possible only if water is released from the upstream
reservoirs or by impounding water upstream. Moreover water is to be
released every time it is required.
*:* Full-fledged treatment plant is to be set up at Sannidhanam and Pamba
for the treatment of waste water and garbage.
*:* A scientifically designed drainage system is to be developed with an
updated sewage disposal facility at the Sannidhanam, and Pamba.
