Groundwater Quality Assessment: A Case Study of Manpur, India

The main objective of this study is to evaluate the groundwater quality in the Manpur block of Gaya District, Bihar, India for drinking purpose. Collection, process and analysis of different physicochemical parameters such as pH, calcium, magnesium, conductivity, total hardness, total alkalinity, total dissolved solids, nitrate, chloride, fluoride, sulphate, iron and arsenic have been conducted for about one hundred ten groundwater samples. The study revealed that in all the groundwater samples pH, chloride, total arsenic, magnesium, nitrate and sulphate were found under the BIS acceptable limit. The pH was negatively and arsenic was not correlated significantly with most of the analysed parameters. The positive correlations are seen among electrical conductivity, alkalinity, total dissolved solids and total hardness and also with calcium, magnesium, sulphate, nitrate and chloride. Whereas iron and fluoride were not significantly correlated to each. The total dissolved solids, total alkalinity, total hardness, iron, fluoride and calcium exceeded the BIS acceptable limit which severely affects the groundwater in the study area.
