A preliminary reconnaissance survey has been undertaken to identify the major noise generating sources in the area. Ambient noise monitoring was conducted at 2 locations in the nearby area of the project site as given in Table 3.4. Table 3.4 Details of Ambient Noise Monitoring Stations S. No. 1. 2. 3.2.2 Locn. Code Location Name/ Description N1 Near Main Gate N2 Back side of the building Present Landuse Residential Residential Methodology of Noise Monitoring Noise levels were measured using integrated sound level meter manufactured by Quest Technologies. The integrating sound level meter is an integrating/ logging type with Octave filter attachment with frequency range of 31.5 to 16000 Hz. This instrument is capable of measuring the Sound Pressure Level (SPL), Leq and octave band frequency analysis. Noise level monitoring was carried out continuously for 24-hours with one hour interval starting at 0030 hrs to 0030 hrs next day. The noise levels were monitored on working days only. During each hour Leq were directly computed by the instrument based on the sound pressure levels. Lday (Ld), Lnight (Ln) and Ldn values were computed using corresponding hourly Leq. 3.2.3 Monitoring was carried out at ‘A’ response and fast mode. Ambient Noise Monitoring Results The time wise ambient noise monitoring results is summarized in Table 3.5. The time-wise variation of noise levels are graphically presented in Figure 3.2.

Discussion on Ambient Noise Levels in the Study Area Day Time Noise Levels (Lday): The day time noise level at all the locations were found to higher than the limit at the back of the building while the levels were found within the limit at the front gate prescribed for Residential area i.e. 55 db(A). Night Time Noise Levels (Lnight): The night time noise level at all the locations were found within the limit prescribed for Residential area i.e. 45 dB (A). 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 impacts of the project on the groundwater quality. Water sample was collected from one location near the project site. The sample was analyzed for various parameters to compare with the standards for drinking water as per IS: 10500 for ground water sources. The details of water sampling locations are given in Table 3.6. Table 3.6 Details of Water Quality Monitoring Station S. No. 1. 3.3.2 Locn. Code Location Name/ Description GW1 Near Project Site Methodology of Groundwater Quality Monitoring Sampling of ground water was carried out on September 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 ITL Labs Pvt. Ltd., Delhi 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.

Haryana Half-yearly Compliance Report of EC Conditions 3.3.4 Page 16 of 17 Discussion on Groundwater Quality in the Study Area The ground water quality in the project area is observed to having total alkalinity up to 328 which is slightly higher than desirable limit of 200 mg/L. Total dissolved solids in the ground water is 1670 mg/L which is higher than the prescribed limit of 500 mg/L. 3.4 SOIL MONITORING 3.4.1 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 near area of project site for studying soil characteristics, the location of which is listed in Table 3.8. Table 3.8 Details of Soil Quality Monitoring Location S. No. 1. 3.4.2 Locn. Code S1 Location Name/ Description Nearby area of Project Site 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 May 2014. 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 Spectrophotometer and Inductive Coupled Plasma Analyzer. 3.4.3 Soil Monitoring Results The physico-chemical characteristics of the soil, as obtained from the analysis of the soil sample, are presented in Table 3.9.
