3.4.2 Methodology of Groundwater Quality Monitoring

Sampling of drinking water was carried out on April 2015. 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 Envirolab, Gurgaon for further analysis. Proper care was taken during packing and transportation of samples. 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 drinking water are given in Table 3.11.

3.6 SOIL MONITORING

3.6.1 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. One sample of soil was collected from the project site for studying soil characteristics, the location of which is listed in Table 3.15.

Table 3.15 Details of Soil Quality Monitoring Location


1. S1 Near Project Site

3.6.2 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 April 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.

3.6.3 Soil Monitoring Results The physic - chemical characteristics of the soil, as obtained from the analysis of the soil sample, are presented in Table 3.16.

Table 3.16 Physico-Chemical Characteristics of Soil in the Study Area

3.6.4 Discussion on Soil Characteristics in the Study Area The soil in study area is characterized by moderate organic content. The soil quality in the project area has not been affected by the project activities.
