Noise level in ambient and source was monitored by using a calibrated Sound Level Meter of Envirotech make, Model No. SLM-100. The instrument has a range to record noise level between 30 – 130 dB. Noise level was monitored inside the property premises at selected location for day and night time, continuously for 24 hours. Day time was reckoned in between 6 AM to 10 PM while between 10 PM to 6 AM, it was considered as night time (Reference: Schedule of the Noise Pollution (Regulation and Control) Rules, 2000). The noise equivalent levels (Leq) were recorded at different locations and reported in the unit of dB (A). Sound Pressure Level (SPL) from acoustic enclosed DG sets was taken at a distance of 1 meter from the source and Leq values were reported in dB (A).

3.2.3 Ambient Noise Monitoring Results The location wise ambient noise monitoring results is summarized in Table 3.5. The location wise variation of noise levels are graphically presented in Figure 3.2.

3.3 GROUNDWATER QUALITY MONITORING 3.3.1 Groundwater Quality Monitoring Locations

Keeping in view the importance of groundwater as an important source of drinking water to the local population, sample of ground water was collected from the project site for the assessment of post-project impacts of the project on the groundwater quality. Grab samples were collected from three registered bore wells available in Building No. 14, Building No. 8 and Building No. 6 of DLF Cyber City, Gurgaon. The samples were collected in clean and dry containers and preserved in ice box in the manner, as prescribed in IS 3025 (Part 1). The samples were transported to the laboratory for further testing and analysis. Details of Groundwater Quality Monitoring are given in Table 3.7. The test results were analyzed with reference to the Indian Standards Specification for Drinking water IS 10500: 2012.

Based on the analysis of selected test parameters and concentration of Iron as Fe the bore well water samples indicate that the ground water, without any treatment, is not fit for human consumption. However, as the building construction project has no direct link with the concentration of iron, it could be concluded that impact of the project operation has minimal impact on the ground water quality.

3.4 SOIL MONITORING 3.4.1 Soil Monitoring Locations

The objective of the soil quality monitoring is to assess the impacts of post-project activities on soil quality. 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. Details of soil sampling location are given in Table 3.8

3.4.2 Methodology of Soil Monitoring

Two samples of top soil, from a depth of nearly 6″ 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 IS: 2720, IS: 14767, IS: 14765 and STM prepared with reference to Methods Manual, Soil Testing in India by Department of Agriculture & Cooperation, Ministry of Agriculture, Government of India, New Delhi, January, 2011.

i. The pH value was found to be in the range of 8.32 – 8.94, which is close to the desired range (6.0–7.5) for horticultural purpose. However, with reference to Methods Manual Soil Testing in India published by Department of Agriculture & Cooperation, Ministry of Agriculture, Government of India, New Delhi, January, 2011: Based on soil pH values the soil could be described as moderately alkaline.

ii. Electrical conductivity in the soil samples was recorded to be in the range of 0.112 and 0.284 milimhos/cm, which shows that the total soluble salts is normal and salinity effect of the soil is negligible, except for some highly sensitive crops.

iii. Organic matters in the samples were found to be 0.6 % and 1.8 %. Organic carbon concentration was 0.3 % and 1%. Soil sample from B-14 and B-10 were found to be within the desired optimum level between 0.5 and 1.0%.

iv. Boron as B, in both the soil samples, was found to be comprising of below critical limit of 0.5 ppm,

There is no standard specified by Central Pollution Control Board and the Ministry of Environment & Forests to govern the soil pollution. However, analysis of the above test results indicates that soil in the project area is not contaminated nor it has been has not been affected by the project activities.

lvl Construction spoils, including bituminous material and other hazardousmaterials, must not be allowed to contaminate watercourses and the dumpsites for such material must be secured so that they should not leach intothe ground water and any hazardous waste generated during constructionphase, should be disposed off as per applicable rules and norms withnecessary approval of the Haryana State Pollution Control Board.
