The Rooppur Nuclear Power Plant (RNPP) at Ishwardi, Bangladesh is planning to go into operation within 2024 and therefore, adjacent areas of RNPP gaining adequate attention from the scientific community for environmental monitoring purposes especially water resources management. However, there a substantial lack literature as well datasets earlier years since very little was done beginning RNPP's construction phase. Therefore, this study conducted assess potential toxic elements (PTEs) contamination in groundwater its associated health risk residents part during year 2014–2015. For achieving aim study, samples were collected seasonally (dry wet season) nine sampling sites afterwards analyzed quality indicators such temperature (Temp.), pH, electrical conductivity (EC), total dissolved solid (TDS), hardness (TH) PTEs including Iron (Fe), Manganese (Mn), Copper (Cu), Lead (Pb), Chromium (Cr), Cadmium (Cd) Arsenic (As). This adopted newly developed Root Mean Square index (RMS-WQI) model scenario whereas human assessment utilized quantify toxicity PTEs. In most sites, concentration found higher season than dry Fe, Mn, Cd As exceeded guideline limit drinking water. RMS score mostly classified terms "Fair" condition. non-carcinogenic risks (expressed Hazard Index-HI) revealed that around 44% 89% adults 67% 100% children threshold set by USEPA (HI > 1) possessed through oral pathway season, respectively. Furthermore, calculated cumulative HI throughout period. carcinogenic (CR) PTEs, magnitude decreased following pattern Cr Cd. Although current based on old dataset, findings might serve baseline reduce future hazardous impact power plant.

Abstract Groundwater quality in arid areas is an issue that requires attention, as often the only source of irrigation and drinking. In this manuscript, a research area 4590.2 Km 2 , which depicts important problems water scarcity water-poor environment, was assessed. Therefore, GIS-based mapping region carried out to examine adequacy groundwater quality. Forty-three (43) samples were gathered fieldwork March 2022, various physicochemical limits analysed within Gibbs Piper diagrams. Likewise, spatial distribution maps twelve (12) main parameters performed using Inverse Distance Weighted interpolation method (IDW) ArcGIS tool. The Water Quality Index (WQI) has been calculated considering Algerian drinking standards know suitability for human consumption. A Pearson’s test explore correlations among different variables. Major results study showed that, anions cations, sulphates ( $$SO_{4}^{ - 2}$$ S O 4 - 2 ) calcium (Ca) most common ions. WQI 30.23% have excellent quality, 62.79% belong good category, 6.97% fall into poor category. Thus, correlation between many properties also significant positive relationships WQI, TDS, EC, TH, $${\text{SO}}_{4}^{ SO $${\text{Ca}}^{ + }$$ Ca + $${\text{Mg}}^{ Mg . agreement with diagram, field rock-water interaction dominance. Hence, shows GIS joint approaches could be useful tools decision-making process local international authorities resources management.
