Arsenic Contamination in Groundwater of Haryana’s National Capital Region and Their Comparative Assessment (Mahendragarh, Rewari, and Jhajjar Districts)

The present study is a comparative research paper on arsenic contamination in groundwater between three districts in Haryana, India: In terms of Mahendragarh, Rewari and Jhajjar, based on the data obtained. This research highlights the extent of arsenic in multiple water sources, its prevalence and variability, as well as factors that may contribute to its levels, health impacts, and implications for agriculture. The results indicate a clear regional pattern, with arsenic contamination being most pronounced in Mahendragarh and having the highest variability of values in Jhajjar. Statistical analysis has proved that these differences are very significant. The variability in the patterns of contamination is due to a complex interaction of the geological and hydrogeological factors, climatic and soil conditions as well as human influences. On top of that, the research also addresses associations between arsenic exposure and health symptoms among different arsenic populations and hypothesizes that exposure variability is an important factor in determining health. Concerns regarding effects on agriculture and bioaccumulation in crops are also discussed. This research sheds light on the pressing need for remedial action, public health measures and ongoing monitoring in order to combat the massive arsenic contamination crisis and its impacts on human health and agricultural viability in impacted areas.
