Knowledge on water quality and its assessment, is necessary for both human health environmental benefit. To account spatial distribution, surface parameters were analysed using integrated interpolation, geographical information systems (GIS) multivariate analysis. A total of 19 locations 13 indicators analysed, a duration six years (2018-2024). The study’s main objective was to assess the seasonal regional variations in index (WQI) Mahanadi River Odisha (N) pi, (S) pi , (O) (C) (E) y -WQI, Int w -WQI Multivariate Statistical tools namely Factor Analysis (F ). However, current investigation, pH, HCO 3 - Na + K Mg 2+ within permissible limits as per WHO standards. According this study, order prevalence ion concentrations signified follows: > Ca cations Cl SO 4 2- anions. analysis indicated that about 15.79% sampled area, affected by turbidity content, which highly unsuitable consumption. remaining area (84.21%) safe category water. Classification based represents most samples falls between good quality. Three noted result excessive TDS EC. In case over 84.21% fell into categories excellent, indicating suitability activities. Using results from model, reflects out samples, 16 suitable drinking. Whereas 2 polluted 1 seriously polluted, thus promotes unsuitability. Although there are several established techniques calculating WQI, study uses consider variety concerns cohesive manner. Meanwhile, y- 84.30% excellent whereas 10% 5% poor high category.

Integrated study of hydrochemistry, quality and risk to human health of groundwater in the upper reaches of the Wulong River Basin

PLoS ONE, Год журнала: 2024, Номер 19(10), С. e0312000 - e0312000

Опубликована: Окт. 21, 2024

Groundwater, a vital source of water supply, is currently experiencing pollution crisis that poses significant risk to human health. To understand the hydrochemical formation mechanisms, quality and health groundwater in upper reaches Wulong River basin, 63 sets samples were collected analyzed. A combination mathematical statistics, correlation analysis, Gibbs diagram, ion ratio, cation exchange comprehensively employed for further index (WQI) assessment conducted. The results indicate generally neutral weakly alkaline. dominant cations are Ca 2+ Mg , while main anions HCO 3 − SO 4 2− . types mainly include ·SO -Ca, -Ca -Na. diverse due fractured discontinuous nature aquifers. characteristics influenced by dissolution silicate carbonate minerals, processes, anthropogenic pollution. presence NO primarily attributed agricultural activities. categorized as "Good" (36.6%) "Poor" (60.8%). "Very poor" "Excellent" categories rare, accounting only 1.2% 1.4%, respectively, no classified "Non-drinkable". Ew i highest, indicating severe contamination Human reveals posing exposure risks account 82.54% children 79.37% adults. This study highlighted nitrate has deteriorated quality, It also suggests an urgent need enhance research protective measures similar regions, such Shandong Peninsula.
