✦ Synopsis

"Groundwater Quality: Assessment and Environmental Impact first discusses arsenic contamination in groundwater, which has emerged as a major health hazard in India. The authors review a generalized scenario of groundwater in the Greater Dhaka Area, focusing on the deterioration of groundwater quality over the years and its impact on the environment. Following this, the chemical composition of rainwater and groundwater from the Mount Cameroon area in May-July 2017 is analyzed, and the impact of water-rockinteractions on groundwater chemistry is assessed. The concluding study aims to assess the extent of exposure to fluoride in inhabitants of Raebareli district in Uttar Pradesh, India, generating baseline data about the fluoride-contaminated area"--
