Water is essential for life, as it supports bodily functions, nourishes crops, and maintains ecosystems. Drinking water crucial maintaining good health can also contribute to economic development by reducing health-care costs improving productivity. The present study evaluated the surface quality of Mahanadi River (Odisha, India). Hence, evaluate hydro-chemical processes, sources contamination, quality, a methodical examination was conducted using an integrated approach, namely Bayesian Approximation (BA), Analytical Hierarchy Process (AHP)-Technique Order Preference Similarity Ideal Solution (TOPSIS), Fuzzy Logic (FL), Multi-Objective Optimization on Basis Ratio Analysis (MOORA), Random Forest (RF) method. For this, samples from 16 locations were taken period 2018–2024, test 21 physicochemical parameters in selected sampling sites. From assessment parameters, with respect WHO standards, pH indicates alkaline, TKN, TC all surpassed prescribed drinking limit. However, major ion hardness spatial interpolation maps typically show that declines upstream downstream, extreme values found downstream. index BA-WQI value revealed 50% belong unsatisfactory quality. This accompanied several parameter's high values, TDS, NO3−, Cl−, SO42−, which highest among locations. Again, noticed 12.50% sites come under zone excellent water. 37.50% indicated class. As result, renowned MCDM model, such AHP-TOPSIS, presented, makes use rough set theory weights provide trustworthy objective total pollution levels at each sample site. this innovative technique depicted W-(9) most polluted region if compared other places, followed W-(8), (16), (2), (7), respectively. Based FL-DWQI 12.5% monitored specimens point towards category, rest 18.75% remaining samples, or 68.75%, consist 'poor, very poor, unsuitable qualities'. relevant degree these stations more closely linked variety expanding human activities, excessive use, fertilizer effects, agricultural runoff, industrial activity around river corridor. Additionally, MOORA has been performance scores extracted. These four W-(9), (8), (4), contain higher scores, 0.89, 0.093, 0.06, 0.04. places containing variables exceeded limits, account coliform, EC properties, named accordingly. It discovered main causes river's adulteration runoff home waste Furthermore, RF analysis carried out five critical TH, EC, obtained basis R2 RMSE score.

Multivariate statistical analysis of chemical and stable isotopic data as indicative of groundwater evolution with reduced exploitation

Geoscience Frontiers, Journal Year: 2022, Volume and Issue: 14(1), P. 101476 - 101476

Published: Sept. 12, 2022

Groundwater resources in the North China Plain (NCP) are undergoing tremendous changes response to operation of groundwater exploitation reduction (GWER) project. To identify evolution this complex context, hierarchical cluster analysis (HCA) and principal component (PCA) were combined interpret an integrated dataset stable isotopes chemical data from four sampling campaigns a pilot area control. We proposed novel HCA approach integrating signals, which successfully partitioned samples into unconfined confined water samples. Stable isotopic evidence showed that lateral inflow surface may contribute more recharge region than local modern precipitation. The water's main hydrochemical types Na type with mixed anions, Na–Cl–SO4 type, while was mainly Na–Cl Na–SO4 types. Geochemical processes involved dissolution/precipitation halite, gypsum, Glauber's salt, feldspar, calcite dolomite, as well cation exchange. PCA results water–rock interaction (i.e., salinity-based alkalinity-based processes) predominated evolution, along nitrate contamination resulting fertilizers domestic sewage. GWER project regulated natural chemistry, significantly reduced salinity (mainly Na+, Mg2+, SO42−). This be attributed upward leakage low-salinity at some parts aquifer. Additionally, insignificant reflected impact on aquifer negligible. study facilitates classification effectively areas lack geological data, enhances knowledge such where restoration is progress, important implications for sustainable management similar basins worldwide.

The Palm Grove ecosystems situated in the southeastern region of Morocco are highly vulnerable to compromise, encountering significant challenges due insufficient precipitation and limited availability groundwater. objective this study is evaluate groundwater quality Tinejdad-Touroug aquifer for domestic irrigation purposes. Groundwater flows from southwest northeast mostly Quaternary conglomerate-lacustrine facies Rheris basin. results show that domination major ions following order: Cl − >HCO 3 >SO 4 2− >Na + >Ca 2+ >Mg >NO >K 2 >NH . Piper diagram showed predominance a single mixed chemical Cl-SO -Ca-Mg, as well presence exceptions some samples other variations. water index (WQI) assessments campaigns were examined demonstrate recorded percentages poor ranged 40% 90% while good varied 7.7% 54.5%. remaining reveal different classes with varying percentages. Most sites all had drinking parameters exceeded values established by World Health Organization (WHO) Moroccan standards.
