RESUMEN
Analysis of heavy metals of water samples from Tube wells, Ring wells, Ponds and Rivers were carried out during year 2008 and 2009. Samples were analyzed using standard methods. To assess the quality of drinking water, each parameter was compared with the standard desirable limit of that parameter in drinking water as prescribed by different agencies. The results from the analysis of water show that the highest PH was recorded in premonsoon 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. The statistical parameters such as Mean, Variance, Standard deviation (SD) and Coefficient of variation (CV) were calculated. Correlation Coefficient Matrix among the parameters was calculated and correlations between various parameters were worked out. Significant positive and negative correlations among the parameters were determined.
