The main aim of this research is to evaluate the quality groundwater in parts Anantapur district, Andhra Pradesh, for drinking and irrigation purposes. Groundwater samples were collected from various locations study area during post-monsoon season analyzed different parameters including pH, EC, TDS, Ca2+, Mg2+, Na+, K+, HCO3−, Cl−, SO42−, NO3−. results then compared with water standards World Health Organization (WHO). major ions found following order: Na+ > Ca2+ Mg2+ K+ = HCO3− SO42− Cl− obtained data was mapped using Arc-GIS technique show spatial distribution pattern physicochemical properties ion concentrations groundwater. index showed that 69% are very poor, 31% unfit purposes due effective leaching ions, over-exploitation groundwater, direct discharge effluents, agricultural impact. Based on Gibbs diagram, fall within rock dominance region. majority fell into C3S1 category, which denotes high salinity low sodium moderately suitable purposes, according USSL diagram. According Wilcox classification, 27% 2% deemed doubtful unsuitable, respectively, while farming. In addition, most moderate suitability when evaluated SAR, %Na, PI, RSC, MAR, KR. Most samples, exception a few spots, turned out be irrigation. However, human activity, some had levels contamination higher than allowed needed treated before consumption.

The aim of this study was to assess the nitrate health risks due water consumption via oral and dermal contact routes evaluate geochemical characteristics waters in Umunya area, Nigeria, as implied from ionic ratios, graphical plots, multivariate statistics. This is first human associated with contamination semi-urban. Standard methods were used achieve study. Water commercial household sources sampled. Measured physicochemical properties showed that resources are slightly contaminated. Health hazard quotient (oral) ranged 0–0.5072 for men, 0–0.5994 women, 0–0.6858 children. On other hand, maximum (dermal) children 0.0013, 0.0016, 0.0042, respectively. total index respectively varied 0–0.509, 0–0.601 0–0.690. Overall, it indicated 46.67%, 53.33%, 53.33% samples expose low chronic risk nitrate. However, ingestion higher than absorption. Hydrogeochemical plots revealed Ca2+-Mg2+-HCO3− Na+-HCO3− types, representing recharge base ion exchange processes, respectively, predominant. Principal component analysis R-type hierarchical clustering hydrogeochemical mostly controlled by geogenic factors human-related factors. geology area silicate weathering processes implicated major influencers hydrogeochemistry. For sustainable development improved monitoring insights provided paper considered very beneficial.
