Air Environment

featpic1Air quality monitoring was carried out at nine (9) Locations. The study indicates that, Temperature varied from 15.6 to 32.8ºC, Relative Humidity from 50 to 89 %, maximum wind speed was observed 7.2 m/s and the average wind speed was 1.76 m/s and total rainfall was 309.9 mm during the study period. Predominant Wind Direction was from west direction. The ambient air quality was monitored at nine (9) locations with respect to SPM, PM10, PM2.5, SO2, NOX, CO, O3, Ni, Pb, As, NH3, Benzene ,BaP.Fe and Mn. The AAQ analysis indicates that the concentration of SPM varied from 103 to 232 µg/m3, PM10 from 39 to 78 µg/m3, PM2.5 from 18 to 42 µg/m3, SO2 from 4.0 to 13.2 µg/m3, NOx from 9.0 to 14.1 µg/m3 & CO from 0.1 to 0.16 mg/m3, O3 from 5.0 to 8.3 µg/m3, NH3 from 20 to 31.3 µg/m3, Benzene from 0.10 to 0.29 µg/m3, BaP from 0.10 to 0.29 ng/m3,Fe 16.4 µg/m3 to 26.2 µg/m3 whereas As, Pb, Mn and Ni were not found in the study area.

Water Environment

Water quality sampling was carried out at ten (10) Locations as per the CPCB standards out of which 5 locations were of Surface Water & 5 locations were of Ground water. Samples were collected during study period. Water Samples were analyzed for physical, chemical & biological parameters. Surface water analysis indicates that PH varied from 7.0 to 7.4, BOD from 0.6 to 1.2 mg/L and TDS from 74 to 92 mg/L, whereas Ground water analysis indicates that, PH varied from 6.8 to 7.2 and total Hardness from 85 to 126 mg/L. All the analysis results are below the stipulated standards prescribed by CPCB.

Land Environment

soilSoil samples were collected once during study period from 5 locations within the study area and were analyzed for Physico-chemical and nutrient status. It was observed that the soil within study area is sandy loam. Soil of the study area was observed acidic in nature with pH value ranging between 6.3 and 6.6 at all locations. The bulk density of soil samples varies from 1.24 to 1.36 g/cm3, while porosity varies from 44 to 53 %.

Biological Environment :

A detailed survey has been carried out to assess the floral and faunal species present in the study area. The flora and fauna studies were carried out in different sites representing the entire study area of 10 km radius around the project site. The study shows the Presence of schedule I fauna like Elephas maximus (Hati) in the buffer zone. A site specific wildlife conservation plan has prepared and it has already approved from PCCF, Chief Wildlife Warden, Bhubaneswar, Odisha.

Noise Environment

Noise monitoring was carried out at nine (9) locations as per the standard prescribed by CPCB. Noise levels were recorded in 1 hour interval for 24 hours, once in a month during the study period, at all locations. Noise level varies from 48.12 to 59.42 dB (A) during Day time and 32.21 to 44.32 dB (A) during Night time, which are below the prescribed limits of CPCB.

Traffic Density

Traffic density study was carried out on hourly basis for 24 hours continuously, once during the study period at three (3) locations. It is observed that during the study period, traffic density is mainly higher during the day time. Composition of vehicles reveals that Heavy vehicles constitute 34.86 %, Medium vehicles from 28.69 % and Light vehicles from 23.67 % and others 12.78 %.

Socio-economic Environment

Total population of the study area is 29,575 with sex ratio of 924 females per 1000 males. Literacy rate of the study area is 49.56%; all the villages within the study area are well established with infrastructural facilities such as basic education, drinking water, medical, post & telegraph facilities. The major crop of the area is paddy.
