Ambient air quality monitoring has been carried out at one location, 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.

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 (NO x)
 Carbon Monoxide (CO)
The duration of sampling of PM2.5, PM10, SO 2 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 the 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 instruments have been used for monitoring Particulate Matter
2.5 (PM2.5 i.e. <2.5 microns), and Respirable Dust Sampler APM 450 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 Locations
The main objective of noise monitoring in the study area is to assess the present ambient noise levels in the
nearby area of 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 in the nearby area
of the project site as given in Table 3.4.

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.

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.

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. The analytical techniques and the test methods adopted for testing of ground water are
given in Table 3.7.

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 project site for studying soil
characteristics, the location of which is listed in Table 3.8.

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.
