Description

In rural areas of Maharashtra 85 % drinking water sources are based on groundwater. The unplanned and nonscientific development of groundwater resources has led to an increasing stress on the available resources. Hence the adverse impacts can be observed in the form of quality deterioration. The drinking water samples from various dugwells and borewells from rural areas were chemically analysed for water quality. In Parbhani district samples analysed from year 2015 to 2019 it is found that drinking water samples analysed chemically in year 2016 -17 are free from fluoride and samples chemically analysed in year 2015-16,2017-18 and 2018-19 it is found that 26 samples have fluoride concentration more than 1.5 ppm. It is also found that there is variation in concentration of fluoride in drinking water. The area is mainly occupied by the Deccan trap basalt flows. High concentration of fluoride is observed in deeper aquifers predominantly than shallow aquifers and it is also found that the samples showing fluoride predominantly during the premonsoon period wnen the water level is at deeper level. The physicochemical conditions along with prolonged groundwater residence i.e. lithological groundwater interaction is inferred to be responsible for increasing fluoride concentration in groundwater
