AMBIENT AIR QUALITY MONITORING
2.1.1 Ambient Air Quality Monitoring Stations
Ambient air quality monitoring has been carried out at two locations, First near the
Main gate and second location of Near Project Site the building to assess the ambient
air quality of the 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.

2.1.2 Ambient Air Quality Monitoring Methodology
Monitoring was conducted in respect of the following parameters:

Particulate Matter 2.5 (PM2.5)

Particulate Matter 10 (PM10)

Sulphur Dioxide (SO2)

Oxides of Nitrogen (NOx)

Carbon Monoxide (CO)
The duration of sampling of PM2.5, PM10, SO2 and NO2 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.
13
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.

μg/m3 and 60 μg/m3 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 SO2 and NOx: 80 g/m3 and limit for CO: 2.0

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 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 monitoring was conducted at 2 locations 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 AM to 06:00 AM 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.
2.2.3 Ambient Noise Monitoring Results
The location wise ambient noise monitoring results is summarized in Table 2.5. The

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 April 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 EnviroLab Gurgaon for further
analysis. Proper care was taken during packing and transportation of samples. 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. The analytical techniques and the test methods
adopted for testing of ground water are given in Table 3.7.

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 201.4 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 715.4 mg/L which is higher then prescribed limit of 500 mg/L.
However, remaining parameters are within the CPCB prescribed limits.

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 out.
To assess impacts of ongoing project activities on the soil in the area, the physicochemical 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 May 2012.
The samples have been analyzed as per the established scientific methods for physicochemical parameters. The heavy metals have been analyzed by using Atomic
Absorption Spectro-photometer and Inductive Coupled Plasma Analyzer.
2.4.3 Soil Monitoring Results
Single 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.
