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.

The usage of water from vending machines has spread in both developed and developing countries. Despite their popularity, various studies documented on low quality drinking machines. present study aimed to determine physicochemical (pH, electrical conductivity (EC), Total Dissolved Solids (TDS), turbidity, Chloride, Nitrate, Sulphate, Phosphate , Calcium carbonate) bacteriological (E.coli bacteria total coliform) parameters selected parts Dar es Salaam region, Tanzania. Nine samples randomly were collected tested for parameters. pH, dissolved solids (TDS) measured using a multiparameter meter. Turbidity was determined turbidimeter, while Phosphate, carbonate analyzed spectrophotometer. Bacteriological analysis, including E. coli coliforms, conducted cultural biochemical methods. average results the tests as follows: pH 7.32, 969 mg/L, 506 turbidity 1.84 NTU, Chloride234.90 Nitrate 3.3 Sulphate 183 phosphate 0.39 calcium 262 mg/L. Physicochemical suitable met World Health Organization (WHO) Tanzania Standards guidelines water. For coliform count, majority (78%) excellent Escherichia all (100%) excellent. Therefore, concluded that, is fit human consumption. In order safeguard public health, recommends awareness, regular testing monitoring its quality.

Contaminated drinking water poses a significant threat to public health, particularly in urban areas where industrial and environmental pollutants may affect quality. However, there is lack of comprehensive studies that evaluate the specific health risks associated with harmful metal contaminants water. This study seeks address this gap by assessing quality contamination using pollution indices human risk assessments. The findings will help identify potential for residents guide development targeted interventions improved management strategies. groundwater samples were collected from five different zones Kasur rural area. A total 25 random sampling hand pumps during 4 months (March–June, 2021) determining various physiochemical attributes (pH, electric conductivity, turbidity, hardness, chloride, phosphate) potentially toxic elements (arsenic, cadmium, lead) standard protocols. Results revealed almost all physicochemical close World Health Organization (WHO) guidelines. assessment pH levels ranged 7.4 9.0, electrical conductivity (EC) between 150 µS/cm 800 µS/cm, average turbidity 12 ± 3.29 NTU, hardness varied 200 1000 mg/L. Chloride phosphate concentrations averaged 304 1.28 mg/L 4.51 1.99 mg/L, respectively. Cadmium 0.15 0.53 while lead arsenic reached up 7.47 exceeding WHO Heavy index (HPI) values sites less than critical value 100. considering HPI classes, locations had high (> 30) class indicating critically polluted heavy metals.
