Physiochemical Analysis of Rain Water and Surface Water Collected from Siltara Industrial Area, Raipur

Abstract

ABSTRACT
A physicochemical analysis of rainwater collected from 04 station of the Siltara Industrial Area, Raipur was carried out during the months of May and June. The pH ranged from 6.20 to 6.80 whereas the acidity of water measured between 1.50 and 5.0 mg/L shows that there is a little bit of abnormal condition of environment in the industrial area here. The higher concentration of nitrate up to 0.25 mg/L has also shown the pollution load in the area. Hardness shows a little variation of 0.00 to 2.00 ppm. Heavy metal or toxic metal concentration was found negligible. Zn was found between 0.04 and 0.08 while Pb, Hg and Cr were found below the detectable limit although iron appeared in a small quantity. The obtained data shows the order of different species contributing to acidic and alkaline depositions in rain water of four stations of the industrial area, Siltara, Raipur. All the detected characteristics of pollutants of anthropogenic origin were detected after first stages of rainfall from the month of May which is due to the changes in atmospheric and environmental conditions of the country. The high concentration of TSS (29–53.00 mg/L) also shows the drastic concentration of atmospheric conditions in the Industrial area here. This particulate matter settles during dry fall, and is rapidly washed out by the early stage of rainfall.
