Published: March 10, 2022

The main objective of the present study is to perform risk assessment groundwater contaminated by nitrate (NO3-) and evaluate suitability for domestic purposes in Palani region South India. Thirty samples were collected area. Various quality analysis parameters such as pH, electrical conductivity, total dissolved solids, hardness, major cations (Ca2+, Mg2+, Na+, K+), anions (Cl-, SO42-, F-, CO32-, HCO3-) adopted this drinking water according 2011 World Health Organization (WHO) standards. Piper Gibbs's diagrams tested indicated that, due influence rock-water interactions, evaporation, reverse ion exchange, chemical composition varied. According index (WQI) mapping results, 46.67% sample locations was identified zones via GIS spatial analysis. Multivariate statistical methods, principal component analysis, cluster Pearson correlation matrix, applied better understand relationship between parameters. results demonstrated that 40% could be highly affected a high concentration. noncarcinogenic health risks among men, women, children reached 40, 50, 53%, respectively. illustrated women occurred at higher than did men region. sources contamination included discharge from households, uncovered septic tanks, leachate waste dump sites, excess utilization fertilizers agricultural sector. Furthermore, using hazard integrated method with conventional indexing approach ensures reliability can guaranteed, explored, appropriate remedial measures implemented.

The precise selection of agricultural land is essential for guaranteeing global food security and sustainable development. Additionally, suitability (AgLS) analysis crucial tackling issues including resource scarcity, environmental degradation, rising demands. This research examines the synergies trade-offs among development goals (SDGs) using a hybrid geographic information system (GIS)–fuzzy analytic hierarchy process (FAHP)–geostatistical framework AgLS in Attur Taluk, India. area was chosen its varied agro-climatic conditions, riverine habitats, importance. Accordingly, data from ten topographical, climatic, soil physiochemical variables, such as slope, temperature, texture, were obtained analyzed to carry out study. geostatistical demonstrated spatial variability parameters, providing insights into key factors study area. Based on receiver operating characteristic curve analysis, results showed that FAHP method (AUC = 0.71) outperformed equal-weighting scheme 0.602).

Abstract The specific objective of the present is to evaluate human health issue due continuous consumption nitrate-contaminated groundwater among various age groups people. In study, 40 samples were collected during post-monsoon season, and major ions analysed in a laboratory. Chadha plot revealed that weathering parent rocks, ion exchange process leaching salts from rocks are primary sources contamination. Nitrate concentration varied 24 78 mg/L with mean 46.45 mg/L. Nitrogen pollution index (NPI) value divulged 40% 17.5% sample locations moderately significantly polluted elevated nitrate groundwater. risk assessment model issues which infants > kids children aged peoples adults. nitrate’s identified using synthetic fertilizers, uncovered septic tanks improper disposal household waste residential area.

Performances of MLR, RBF-NN, and MLP-NN in the evaluation and prediction of water resources quality for irrigation purposes under two modeling scenarios

Geocarto International, Journal Year: 2022, Volume and Issue: 37(26), P. 14399 - 14431

Published: June 9, 2022

One of the pivotal decision-making tools for sustainable management water resources various uses is accurate prediction quality. In present paper, multiple linear regression (MLR), radial basis function neural network (RBF-NN), and multilayer perceptron (MLP-NN) models were developed monitoring irrigation quality (IWQ) in Ojoto area, southeastern Nigeria. This paper first to integrate simultaneously implement these predictive methods modeling seven IWQ indices. Moreover, two scenarios considered. Scenario 1 represents predictions that utilized specific physicochemical parameters calculating indices as input variables while 2 pH, EC, Na+, K+, Mg2+, Ca2+, Cl-, SO42-, HCO3- inputs. terms salinity hazard, most are unsuitable/poor irrigation. However, carbonate bicarbonate impact magnesium majority samples have good excellent IWQ. Seven agglomerative Q-mode dendrograms spatiotemporally classified based on Model validation metrics showed MLR, RBF-NN, MLP-NN performed well both scenarios, with minor variations.
