Water quality index and health risk assessment for heavy metals in groundwater of Kashiani and Kotalipara upazila, Gopalganj, Bangladesh

Applied Water Science, Journal Year: 2024, Volume and Issue: 14(5)

Published: April 25, 2024

Abstract The groundwater quality of the Gopalganj district in Bangladesh was not well documented. Therefore, this research done to determine study area. water index and human health risk for heavy metal ingestion were used describe quality. performed through estimation turbidity, pH, electrical conductivity, total dissolved solids, concentration sodium, potassium, ammonium, nitrate, iron, manganese, zinc, copper, arsenic. mean solids two upazila within permissible limit. However, conductivity both higher than WHO-prescribed value which Kotalipara. Excess concentrations iron arsenic found Kashiani upazila, but these below detection limit Kotalipara upazila. revealed that roughly 61.0% samples poor about 96.0% excellent Chronic risks due revelation drinking have also been determined by assessing hazard quotient index. In Kashiani, almost 85.0% elevated chronic adults 100.0% very high children. Kotalipara, all (almost 100%) suggested a lower results carcinogenic via oral exposure children

Determination of water quality and efficient removal of arsenic and iron from groundwater using mahogany fruit husk and banana peduncle charcoals

Results in Engineering, Journal Year: 2024, Volume and Issue: 22, P. 102220 - 102220

Published: May 4, 2024

The groundwater (GW) of Bangladesh is predominantly contaminated with arsenic (As) and iron (Fe) which has a bad impact on human health. We tried to remove these elements easily available mahogany-fruit (Swietenia mahagoni) husk charcoal (MHC) banana (Musa acuminata) peduncle (BPC). trial was implemented 3 replications throughout the research. sampled GW contained 0.06 mg As L-1 4.83 Fe L-1. Firstly, pH 3, 5, 7, 9 250 dose. MHC removed almost 91.05% at 5.0, BPC 86.67% 9. However, in case Fe, 100% 7 9; same quantity Secondly, contact times were 0, 10, 20, 40 minutes dose 7.0. maximum removal 5 minutes. pseudo-first-order kinetic, pseudo-second-order intra-particle diffusion models considered. result showed that rate adsorption followed kinetic model. Lastly, adsorbent doses 50, 150, 250, 350 At highest 79.47% for MHC. Similarly, values 79.29% BPC, indicating are good heavy metals removal.

Mapping and assessing impacts of land use land cover and climate conditions on groundwater quality using RS & GIS

Applied Water Science, Journal Year: 2025, Volume and Issue: 15(3)

Published: Feb. 19, 2025

Abstract Groundwater is an essential source for drinking purposes; hence, a qualitative analysis necessary groundwater resources. This study aims to assess the impacts of dynamic land use cover (LULC) and climatic conditions on quality purposes. The investigative research used water index (WQI) analyze identified using LULC map conditions. It extends integrated combined approach different aspects. provides comprehensive understanding how various factors influence quality. total area classified as excellent, good, poor, very unfit consumption based WQI. results concluded that only 10.17% has excellent quality, 19.97% good 9.013% 5.73% have poor respectively, 55% consumption. indicated areas with agricultural expansion, urban development, some natural such topographic features high soil erodibility led dissolved solids, electrical conductivity levels, heavy metals. main lead contamination include expansion development. On other hand, conditions, variations in temperature precipitation, also influenced aids examining perspectives, which will lend hand managers make suitable decisions sustainable development plans conserve economically important region.

Assessment of surface water quality parameters using multivariate analysis—A case study of Kurichi and big lakes in Coimbatore

Water Environment Research, Journal Year: 2025, Volume and Issue: 97(3)

Published: March 1, 2025

Abstract Water quality deterioration due to industrialization and urbanization is a growing environmental concern, particularly in developing regions. This study assesses the surface water of Kurichi Big Lakes Ukkadam area, Coimbatore, India, using multivariate statistical techniques identify key pollution sources evaluate contamination levels. Despite prior research on urban lakes, limited studies have systematically analyzed multiple contaminants advanced approaches. A total 12 samples were collected between June 2023–June 2024 for physicochemical, microbiological, anionic parameters. Principal Component Analysis (PCA) Factor (FA) revealed three dominant components explaining 68.42% 42.81% variance Lakes, respectively. The Piper plot classified types, while Cluster (CA) grouped sampling sites based Pearson correlation matrix determined pollutant interdependencies, Quality Index (WQI) categorized severity against WHO BIS standards. results indicate that organic matter, industrial discharge, fertilizer runoff, untreated wastewater are primary contributors pollution. High levels detected near zones, with Lake exhibiting significantly poorer than Lake. findings highlight urgent need improved management control policies safeguard aquatic ecosystems public health. Practitioner Points Multivariate Statistical Analysis: Applied PCA, FA, plot, CA, assess quality. Classification: Identified Findings: Three major explained variation Major Pollution Sources: analysis identified compounds, human activity, fertilizers, chemical waste, discharge as contaminants. Industrial Area Impact: CA WQI highlighted high sensitivity zones
