Study on the ground water quality in and around tanning industry, Tiruchirappalli, India

摘要

The present investigation was undertaken to study the impact of tanning industry on the ground water quality of five sampling station situated around the cluster of tanneries of Sempattu, Tiruchirappalli. The physical and chemical parameter such as pH, TDS, TSS, TS, Total Alkalinity, Total hardness, Chlorides, DO, BOD, COD Nitrate, Phosphate and Silicate were analyzed. Clear variations were observed with respect to various parameters among the five stations. Ground water sample collected from Station2 maintained higher values of solids, alkalinity, hardness and COD when compared to the other station. The values of dissolved solids were very high in all the villages. Although a few parameters were within the permissible limits, the ground water quality of study area is not suitable for drinking purpose and nobody in using it so for, obviously due to deteriorated condition. The total heterotrophic bacterial population count estimated for different sampling stations, the colony forming unit (CFU) values for total count fluctuated between 0.92 X 10~2 and 2.68 X 10~2 CFU/mL.
