AMBIENT AIR QUALITY MONITORING
2.1.1
Ambient Air Quality Monitoring Stations
Ambient air quality monitoring has been carried out at two locations, one being near the main gate
and one location is near the parking area of 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.

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 were 8 hourly continuous monitoring this is to
allow a comparison with the National Ambient Air Quality Standards. 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.

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 front 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 three locations at the boundary of the
project site as given in Table 2.9.

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

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 near 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

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.
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

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 36.50mg/L 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 108.50 mg/L which is
lower than 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 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 2.15.

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.
