Statistical Assessment of Water Quality Parameters for Pollution Source Identification in Deepor Beel Area, Guwahati, Assam

This study was carried out in Deepor Beel to assess the water quality parameter by statistical analysis. The samples were collected from nine selected stations covering entire area. The lake's water quality was evaluated based on it’s the locations, and the variations of seasons .Water Pollution issues were identified and quality classes were developed. The adaptability of aquatic life forms has also been demonstrated. 13 physico-chemical and four heavy metal parameters were examined in the lake water for such reasons. The results of the study suggest that non-point pollution that is, soil leaching and agricultural contamination may be the primary cause of pollution in this region. These results at the temporal and spatial scales recommend that water monitoring efforts in the future should be scale-sensitive to water management.
