Qualitative Assessment of Water Sources in Pench Tiger Reserve, Maharashtra

Abstract

To ascertain the quality of water used for drinking purpose, by the consumers and wildlife, water quality monitoring of the groundwater and surface water sources was conducted in Pench Tiger Reserve area in Maharashtra. The fecal streptococci (FS) and fecal coliforms (FC) ranged from 0-5 CFU/100ml and 0-62 CFU/100ml respectively. The bacterial contamination in groundwater may be because of improper source protection and possibility of enroute contamination. Geogenic background has major impact on groundwater quality in Pench with gneisses and basaltic type of formation which reflect on the physicochemical water quality parameters. Water quality parameters like turbidity, fluoride, iron and bacterial counts are above the permissible limit in some water sources making the water unsuitable for drinking purpose. The high turbidity in the groundwater samples is attributed to the presence of iron precipitates. Study area is covered with red ferruginous soils which are rich in iron and contributes to iron content in groundwater. Appropriate treatment is required to reduce down the iron and fluoride concentrations followed by disinfection so that the water quality parameters fulfill BIS guidelines for potability of water. The correlation and regression analysis among different water quality parameters helps in establishing relationships among water quality parameters drawing inferences about them. Water quality monitoring at regular interval with suitable treatment measures is very much essential to provide safe drinking water to the consumers.
