Details of Environmental Monitoring

3.1 AMBIENT AIR QUALITY MONITORING

3.1.1 Ambient Air Quality Monitoring Stations

Ambient air quality monitoring has been carried out at one location, one being Near Main Gate to assess the ambient air quality. This will enable to have an analytical understanding about air quality and the changes in the air environment in the study area with respect to the condition prevailing. The locations of the ambient air quality monitoring stations are given in Table 3.1.

Table 3.1 Details of Ambient Air Quality Monitoring Stations S. Locn. Location Name/ Description Environmental Setting No. Code 1. AAQ-1 Near Main Gate Commercial activities

3.1.2 Ambient Air Quality Monitoring Methodology

Monitoring was conducted in respect of the following parameters:  Particulate Matter (PM10)  Particulate Matter (PM2.5)  Sulphur Dioxide (SO2)  Oxides of Nitrogen (NOx)  Carbon Monoxide (CO)

The duration of sampling of PM10, PM2.5, SO2 and NOx was 24 hourly continuous sampling per day and CO was sampled for 8 hours continuous, thrice in 24 hour duration monitoring. The monitoring was conducted for one day at each location. This is to allow a comparison with the National Ambient Air Quality Standards.

The air samples were analyzed as per standard methods specified by Central Pollution Control Board (CPCB) and IS: 5182. The techniques used for ambient air quality monitoring and minimum detectable levels are given in Table 3.2.

Fine particulate sampler APM 550 instrument have used for monitoring Particulate Matter (PM2.5) i.e. <2.5 micron. Respirable Dust Samplers APM-451 instruments have been used for monitoring Particulate Matter (PM10), Respirable fraction (<10 microns) and gaseous pollutants like SO2, and NOx. Pulse pumps and mylar bags were used for collection of Carbon monoxide samples. Gas Chromatography techniques have been used for the estimation of CO.

PM10 and PM2.5 were observed above the corresponding stipulated limits (100 μg/m3 and 60 g/m3 for residential, rural and other areas as stipulated in the National Ambient 3 3 Air Quality Standards and limit for SO2 and NOx: 80 g/m and limit for CO: 2 mg/m ) at all monitoring locations. Station wise variation of ambient air quality parameters has been pictorially shown in Figure 1.

Figure 3.1 Location-wise Variation of Ambient Air Quality

3.2 AMBIENT NOISE MONITORING

3.1.1 Ambient Noise Monitoring Locations

The main objective of noise monitoring in the study area is to assess the present ambient noise levels in project site & project boundary due to various construction allied activities and increased vehicular movement. A preliminary reconnaissance survey has been undertaken to identify the major noise generating sources in the area. Ambient noise Project: “Nile Tech Limited”, Plot No-16, Phase IV, Udyog Vihar, Gurgaon Half-yearly Compliance Report of EC Conditions Page 14 of 16

monitoring was conducted at 2 locations at near main gate & Backside of the project site as given in Table 3.4.

Table 3.4 Details of Ambient Noise Monitoring Stations S. No. Locn. Code Location Name/ Description Present Land use 1. N1 Near Main Gate Commercial activities 2. N2 Back Side Commercial activities

3.2.2 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. Monitoring was carried out at ‘A’ response and fast mode.

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.

3.2.4 Discussion on Ambient Noise Levels in the Study Area

Day Time Noise Levels (Lday): The day time noise level at both locations were observed to within the permissible limit prescribed for commercial area i.e. 65 db(A).

Night Time Noise Levels (Lnight): The night time noise level at both locations were observed to within the limit prescribed for commercial area i.e. 55 dB (A).

3.3 GROUNDWATER QUALITY MONITORING

3.3.1 Groundwater Quality

Facility at project site is using water through tanker which would be available for consumption after the RO treatment. Since the project site is not having any bore well for the extraction of ground water, ground water monitoring is not required

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 point 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 3.6.

Table 3.6 Details of Soil Quality Monitoring Location S. No. Locn. Code Location Name/ Description 1. S1 Project Site

3.4.2 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 September 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 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 3.8.
