3.5.2 Methodology of Drinking Water Quality Monitoring

Sampling of water was carried out on March 2014. Samples were collected as grab sample and sampling forms are filled in as per the sampling plan. The preservative sample were properly added to preserve as per standard operating procedures (SOP) and stored immediately in ice boxes, which were ensured for appropriate temperatures. Sample for chemical analysis was collected in polyethylene carboys. Sample collected for metal content were acidified to <2 pH with 1 ml HNO3. A sample for bacteriological analysis was collected in sterilized glass bottles. Soon after the completion of sampling, chain of custody sheets for the samples are filled in and then they were transported by road to Vardan Enviro Lab, Gurgaon for further analysis. Proper care was taken during packing and transportation of samples. All the samples reached the central laboratory within the holding times for different parameters. After ensuring the same the samples were forwarded immediately for analysis.

The samples were analyzed as per the standard procedures specified in 'Standard Methods for the Examination of Water and Wastewater' published by American Public Health Association (APHA) and CPCB. The analytical techniques and the test methods adopted for testing of water are given in Table 3.21.

3.5.4 Discussion on Drinking Water Quality in the Study Area

The drinking water quality in the project area is observed to be alkaline in nature with total alkalinity reaching up to 90.10 mg/L against desirable limit of 200 mg/L, however, alkalinity is less than the permissible limit of 600 mg/L. Total dissolved solids in the drinking water is 158.00 mg/L which is lower than prescribed limit of 500 mg/L. However, remaining parameters are within the CPCB prescribed limits.

3.7 SOIL MONITORING 3.7.1 Soil Monitoring Locations

The objective of the soil monitoring is to identify the impacts of ongoing project activities on soil quality and also predict impacts, which have arisen due to execution of various constructions allied activities. Accordingly, a study of assessment of the soil quality has been carried out To assess impacts of ongoing project activities on the soil in the area, the physico-chemical characteristics of soils were examined by obtaining soil samples from selected points and analysis of the same. Single sample of soil was collected from the project site for studying soil characteristics, the location of which is listed in Table3.25.

Table 3.25 Details of Soil Quality Monitoring Location


1. S1 Near Garden Area

3.7.2 Methodology of Soil Monitoring

The sampling has been done in line with IS: 2720 & Methods of Soil Analysis, Part-1, 2nd edition, 1986 of American Society for Agronomy and Soil Science Society of America. The homogenized samples were analyzed for physical and chemical characteristics (physical, chemical and heavy metal concentrations). The soil samples were collected in the month of March 2015. The samples have been analyzed as per the established scientific methods for physico-chemical parameters. The heavy metals have been analyzed by using Atomic Absorption Spectro-photometer.
