The objective of soil monitoring is to identify the impact of ongoing project activities on soil quality and also predict impacts, which have arisen due to execution of various constructions and allied activities and in consonance of the above, take corrective measures. 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 physic-chemical characteristics of soils were examined by obtaining soil samples and analysis of the same. One sample of soil was collected from back side of the site office from a depth of approximately 6’’

to 9” below the earth surface for studying soil characteristics, the location of which is listed in Table 3.8.

3.4.2 METHODOLOGY OF SOIL MONITORING

Samples of top soil, from a depth of nearly 6″-9″ below the surface, were collected from the project premises. The samples were preserved in clean and lock-in polyethylene and transported to the laboratory for testing. Testing was performed with reference to the standard methods prescribed in UL/SOP/EX/02.

The samples were analyzed as per the established scientific methods for physic-chemical parameters. The heavy metals have been analyzed by using Atomic Absorption Spectrophotometer and Inductive Coupled Plasma Analyzer.

3.4.3 SOIL MONITORING RESULTS

The physic-chemical characteristics of the soil, as obtained from the analysis of the soil sample, are presented in Table 3.9.

3.4.4 DISCUSSION ON SOIL CHARACTERISTICS IN THE STUDY AREA

The soil in study area is characterized by slightly alkaline in nature. The soil quality in the project area has not been affected by the project activities. Desirable range of the pH value is 6.0–7.5 for horticultural purpose. pH 6.6 – 6.9 is slightly acidic, 7.1 – 8.5 is moderately alkaline, >8.5 is strongly alkaline.
