Details of Environmental Monitoring

2.1 AMBIENT AIR QUALITY MONITORING

2.1.1 Ambient Air Quality Monitoring Stations

Ambient air quality monitoring has been carried out at 2 locations; one being near the main gate & second one is near project site. This will enable to have a comparative 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 2.1.

AAQ-1: Main GateThe sampler was placed near main gate of building and was free from any obstructions. Surroundings of the sampling site represent residential environmental setting

AAQ-2: Near Project siteThe sampler was placed at project site. Vicinity represents residential environmental setting.

2.1.2 Ambient Air Quality Monitoring Methodology

Monitoring was conducted in respect of the following parameters: Particulate Matter 2.5 (PM 2.5) Particulate Matter 10 (PM 10) Sulphur Dioxide (SO2) Oxides of Nitrogen (NOx) Carbon Monoxide (CO)

The duration of sampling of PM 2.5, PM10, 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 2.2.

Fine Particulate Sampler instruments have been used for monitoring Particulate Matter 2.5 (PM2.5 i.e. <2.5 microns), and Respirable Dust Sampler was used for sampling Respirable fraction (<10 microns), gaseous pollutants like SO2, and NOx. Bladder and Aspirator bags were used for collection Carbon monoxide samples. Gas Chromatography techniques have been used for the estimation of CO.

PM10 and PM 2.5 levels at the project site are within the permissible limit of 100 g/mμ 3 and 60 g/mμ 3

respectively (for residential, rural and other areas as stipulated in the National Ambient Air Quality Standards). SO2, NOx and CO was observed within the corresponding stipulated limits (Limit for SO 2 and NOx: 80 g/m3 and limit for CO: 4.0 g/m3) at all monitoring locations. Station wise variation of ambient air quality parameters has been pictorially shown in Figure 2.1

2.2 AMBIENT NOISE MONITORING

2.2.1 Ambient Noise Monitoring Locations

The main objective of noise monitoring in the study area is to assess the present ambient noise levels in near main gate 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 monitoring was conducted at 1 location at the boundary of the project site as given in Table 2.4.

2.2.2 Methodology of Noise Monitoring

Noise levels were measured using sound level meter.

Noise level monitoring was carried out continuously for 24-hours with one hour interval starting at 06:00 hrs to 06:00 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. Monitoring was carried out at ‘A’ response and fast mode.

2.3 GROUNDWATER QUALITY MONITORING

2.3.1 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 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 2.6.

2.3.2 Methodology of Groundwater Quality Monitoring

Sampling of ground water was carried out on November 2013. 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 Enviro Lab, Gurgaon 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.

2.3.4 Discussion on Groundwater Quality in the Study Area

The ground water quality in the project area is observed to be alkaline in nature with total alkalinity reaching up to 180.30mg/L at project against desirable limit of 200 mg/L, however, alkalinity is less than the permissible limit of 600 mg/L. Total dissolved solids in the ground water is 418.50mg/L at project site against prescribed limit of 500 mg/L. However, remaining parameters are within the CPCB prescribed limits.

2.4 SOIL MONITORING

2.4.1 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 outTo 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. Single sample of soil was collected from the project site for studying soil characteristics, the location of which is listed in Table 2.8.

2.4.2 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 November 2013.

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.

2.4.3 Soil Monitoring ResultsSingle sample of soil is collected from the site to check the quality of soil of the study area .The Physico-chemical characteristics of the soil, as obtained from the analysis of the soil sample, are presented in Table 2.9.
