Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2014, Vol 2, Issue 12
Abstract
A study was conducted in the water samples collected from, Cherlapally fresh water Lake, Cherlapally village, Ranga Reddy district, Telagana state, India. The lake was constructed in the year 1970s, during that time the lake was the main source for drinking and agriculture purpose only. In the past 15 years sewage water from Kapra Village and Kushaiguda areas is entering the fresh water Cherlapally Lake. At the same time many industries like electrical and electronics, earth drilling equipment’s, pharmaceuticals, printing packaging, metal fabrication industries, and bore wells rigs manufacturing companies have come up around the lake. Therefore there is a possibility for heavy metals carrying in to the Lake, for this purpose experiments was done in three sites of the Cherlapally Lake that are site-1 (in-let), site-2 (out-let), and site-3 (middle) for heavy metal pollution. The heavy metal concentrations reported in Lake during the rainy season, 2013: The results indicated that, Mg ranged from 1075.5 to 2209 mg/L, Co from 0.29 to 1.68 mg/L, Cd from 0.35 to 0.92mg/L, Zn from 2.74 to 26.4 mg/L, Mn from 3.22 to 9.22 mg/L, Ca from 2832 to 6318 mg/L, Cu from0.47 to 57.6, Fe (Iron) from 10.2 to 63.82 mg/L, Ni from 5.17 to 14.58 mg/L, K from 6.9 to 20.5mg/, As from 26.8 to 49.38 mg/L, Na from11.56 to 18.36mg/L. The following heavy metals were found to be in high concentrations above the maximum permissible limits prescribed by BIS and WHO water quality guidelines Arsenic, Cadmium, Copper, Nickel, Zinc, and Ferrous. Therefore the lake can be regarded as polluted lake.
