Abstract

Thirty four water samples were analyzed for fluoride and arsenic contamination by adopting standard methods (APHA 2005). In this study, the tools used for data analysis are mainly experimental, aimed at defining possible relationships, trends or interactions among the measured variables of interest. Descriptive statistics in the forms of mean, variance (V), standard deviation (SD), standard error (SE), median, range of variation and percentile at 95%, 75% and 25% are computed for arsenic and fluoride. t test is done under null hypothesis (H0) by taking the assumption that the experimental data are consistent with the mean rating given by WHO (2004). In our investigation the result indicate that TDS, EC, pH, BOD, DO, COD, TSS were found to be very high. In 76% samples turbidity exceeds WHO guideline value 5 NTU. During the investigation we have found that 97% and 76% of the source were found positive for TC and FC. Among the samples the concentration of fluoride were within the permissible limit in most cases but arsenic concentration in five sources were found more than the permissible limit (0.05 ppm) (WHO 2004).
