Our work was aimed at analysis of arsenic metal in drinking water in Malwa region Punjab, which is known to be cancer belt. We have developed a highly sensitive & cost effective colorimetric method for quantifying Arsenic metal in drinking water of and the result of sample analysis has been compared with ICAP-AES method. In addition to this we have observed some new location in Malwa region of Punjab, having high Arsenic in drinking water. Our modified colorimetric method of arsenic determination is sensitive up to 0.0167 mg/L without any interference at 515nm.
