ABSTRACT

 

A total of 20 numbers of samples from different sources such as Tube wells, Ring wells, Ponds and Rivers were collected during year 2008 and 2009. Samples were analyzed for different heavy metals like Copper, Chromium, Nickel, Arsenic and Zinc using standard methods. The results arrived were compared with Indian standards for drinking water to check out their pollution level. The results from the analysis of water show that the highest pH was recorded in pre-monsoon season, but lowest value recorded in monsoon season. All the sources have pH within the maximum limit. The Copper and Zinc concentrations in all sources were below the permissible limit but in case of nickel all the sources have its value exceed the limit. Chromium was detected during post monsoon and winter seasons. Two sources have chromium values exceed the permissible limit. In the present study, maximum amount of arsenic in all seasons is recoded from Ring wells only.
