Water-quality indicators and trace elements were measured in the alluvial area of Kostolac Basin, Serbia. The results revealed that groundwater was naturally neutral, with a mean conductance 920.10 μs/cm. primary factors contributing to decline quality researched electrical conductivity (EC), NO3−, SO42−, Cd, Pb; water samples deemed unfit for human consumption classified as having impaired quality. A Pearson correlation matrix, principal component analysis (PCA), cluster (CA) applied identify pollution source controlling indicated both natural anthropogenic influenced studied area. Nemerow index medium high levels along degree contamination. health risk evaluation conducted determine non-carcinogenic risks posed by nitrates heavy metals from oral skin contact Nearly all monitoring sites had hazard quotients (HQs) below 1, suggesting potential concerns might be negligible. However, children showed highest exposure levels, HQs at 2.26 lead (Pb) 2.515. No carcinogenic found any sample.

Shoreline changes and groundwater quality monitoring have become pressing issues for the coastal region of Bangladesh.This study investigated shoreline from 2000 to 2020 evaluated quality, as well SWI in Kuakata area.While analyzing satellite images, temporal were assessed through Digital Analysis System (DSAS) ArcGIS 10.4.1.Higher erosion rates (>2 m/ year) found southernmost part SE studied area.Twenty-five samples collected, physicochemical parameters measured assess quality.The geographic information system (GIS) was used spatial variation EC, pH, Cl⁻ contents inverse distance weighted (IDW) interpolation method.The Cl⁻, pH values ranged (1.2 mS/cm 19.5 mS/cm), (79.88 mg/L 11241.67 mg/L), (7.9 8.7), repectively.The analysis revealed that majority unsuitable drinking purpose due higher EC values.Saline water intrusion (SWI) determined by using alternative vs method southern beach area, which closest sea.
