Safeguarding drinking water is a major public health and environmental concern because it essential to human life but may contain pollutants that can cause illness or harm the environment. Therefore, continuous research necessary improve treatment methods guarantee its quality. As part of this study, effectiveness coagulation–flocculation using aluminum sulfate (Al2(SO4)3) was evaluated on very polluted site. Samplings were taken almost every day for month from site, samples characterized by several physicochemical properties, such as hydrogen potential (pH), electrical conductivity, turbidity, organic matter, ammonium (NH+4), phosphate (PO43−), nitrate (NO3−), nitrite (NO2−), calcium (Ca2+), magnesium (Mg2+), total hardness (TH), chloride (Cl−), bicarbonate (HCO3−), (SO42−), iron (Fe3+), manganese (Mn2+), (Al3+), potassium (K+), sodium (Na+), complete alkalimetric titration (TAC), dry residue (DR). Then, these treated with Al2(SO4)3 jar test method, which common method determine optimal amount coagulant add based characteristics. A mathematical model had been previously created support vector machine predict dose according parameters temperature, pH, TAC, turbidity. This step repeated at end each year, second characterization carried out in order compare them those raw water. The results showed effective elimination various pollutions, high rate, thus demonstrating Al2(SO4)3. measured after significant reduction majority parameters. These demonstrated eliminating pollutions present They also stress importance continued field quality protect

Groundwater, an invaluable resource crucial for irrigation and drinking purposes, significantly impacts human health societal advancement. This study aims to evaluate the groundwater quality in Mnasra region of Gharb Plain, employing a comprehensive analysis thirty samples collected from various locations, based on thirty-three physicochemical parameters. Utilizing tools like Pollution Index Groundwater (PIG), Nitrate (NPI), Water Quality (WQI), Irrigation (IWQI), as well Multivariate Statistical Approaches (MSA), Geographic Information System (GIS), this research identifies sources pollution. The results revealed Ca2+ dominance among cations Cl− primary anion. Piper Gibbs diagrams illustrated prevalent Ca2+-Cl− water type significance water–rock interactions, respectively. PIG values indicated that 86.66% exhibited “Insignificant pollution”. NPI showed notable nitrate pollution (1.48 7.06), with 83.33% rated “Good” WQI. IWQI 80% were classified “Excellent” 16.66% “Good”. Spatial identified eastern southern sections highly contaminated due agricultural activities. These findings provide valuable insights decision-makers manage resources promote sustainable management region.

This study evaluates the suitability of treated wastewater (TWW: secondary effluent and membrane effluent) for crop irrigation resultant impact on growth soil physicochemical characteristics. Carrot seeds (Daucus carota subsp. sativus) were grown loam irrigated with tap water (Tap), (SE), (ME) until maturity. Bacteriological analyses showed four log counts E. coli thermotolerant coliforms effluent, making it unsafe carrots. Tap fulfilled microbial limit reuse suitable irrigation. The sodium absorption ratio, Kelly index, magnesium hazard assessments indicated that all three streams average mass carrot fruits Tap, SE, ME was 2.14 g, 3.96 3.03 respectively. A similar trend observed dry matter composition: had 15.9%, SE 18.3%, 16.6%. pH increased from 7.08 to 7.26, 7.39, 7.33 water-, effluent-, effluent-irrigated soils, Nitrate-nitrogen potassium levels in TWW-irrigated soil, while water-irrigated decreased. Sodium significantly but did not induce sodicity. application TWW enhanced plants nutrient levels. Hence, using agricultural could promote food production also overdependency freshwater resources. However, should be disinfected by UV disinfection ozonation reduce risk contamination. Such methods may lead formation toxic byproducts, therefore pollution crops is anticipated.

For many years, rare earth elements (REEs) have been part of a wide range applications (from cell phones and batteries to electric vehicles wind turbines) needed for daily life all over the world. Moreover, they are often declared be “green technology”. Therefore, data obtained from United States Geological Survey (USGS) on reserve production underwent treatment using multivariate imputation by chained equations (MICE) algorithm recover missing data. Initially, simple linear regression model was chosen, which only considered fixed effects (β) ignored random (Ui). However, recognizing importance accounting effects, study subsequently employed multilevel Linear Mixed-Effects (LME) model. This allows simultaneous estimation both followed variance parameters (γ, ρ, σ2). The demonstrated that adjusted values closely align with actual values, as indicated p-values being less than 0.05. this effectively captures sample’s error, fixed, components. Also, in range, findings two standard deviation measurements along measurement, exhibits significant predictive capabilities. Furthermore, within timeframe, provided predictions world reserves various countries until 2053, well forecasts through 2051.
