Investigating drinking water quality, microbial pollution, and potential health risks in selected schools of Badin city, Pakistan

HydroResearch, Journal Year: 2024, Volume and Issue: 7, P. 248 - 256

Published: Jan. 1, 2024

This study investigated drinking water quality in public, private, and religious schools Badin city, Pakistan. Physicochemical parameters were within limits except for slightly elevated pH turbidity. The microbial analysis showed that T.C., F.C., found all samples, E. coli 55% respectively, with significant differences quantities. Microbial contaminants correlated positively pH, turbidity, each other, linking them to sewage, runoff, waste. Bacterial counts exceeded WHO guidelines, the pollution load index (PLI) demonstrated declining quality. (WQI) rated samples as 30% "very good," 35% "good," "bad"; none "excellent" or safe drink. Subpar poses health risks children, potentially causing diarrhea, hepatitis A, typhoid. To mitigate risks, infrastructure improvements, education initiatives, public awareness campaigns are necessary securing access support well-being of school children community.

Analysis and insights of groundwater quality and water quality index values with reference to different sources: a case study

International Journal of Engineering Science and Technology, Journal Year: 2025, Volume and Issue: 16(4), P. 11 - 19

Published: Jan. 13, 2025

Groundwater quality variation due to consequent changes in the standard of living a community is great unease owing fact that groundwater regarded as one significant water supply sources available. For sustainable use resources and management, monitoring assessment acts catalyst for an appropriate judgment on quality. In this study, samples were collected from Lingayas Institute Management Technology (LIMAT), Vijayawada campus Mudirajupalem, Krishna district, Andhra Pradesh, India assessing alkalinity, total dissolved solids (TDS), pH, acidity hardness (TH) using methods. Very high values pH TDS obtained which within vicinity agricultural fields. Added this, Student’s t test analysis signposted noteworthy P value (<0.001) mean difference was substantial statistically. The Mudirajupalem further affirmed unfit drinking, evident index (WQI) values. This study emphasizes implementing various locale specific rainwater garnering schemes, solution augmenting recharge maintaining balance.

Spatial variability of groundwater quality in four mega-cities of India and impact of land use types on groundwater quality

Urban Water Journal, Journal Year: 2025, Volume and Issue: unknown, P. 1 - 18

Published: Feb. 3, 2025

The deterioration of groundwater quality is a global concern, particularly in densely populated urban areas. This study examines spatial variability across four major Indian cities – Mumbai, Delhi, Chennai and Kolkata using water index (WQI) remote sensing techniques. Groundwater data from the 2018 report Central Board was analyzed 12 parameters, while Normalized Difference Vegetation Index (NDVI), Water (NDWI) Built-up (NDBI) indices were calculated Landsat imageries to assess land use impacts. Findings indicate significant variability: Delhi shows 44.62% unsuitable samples, 12.12%, 0% Mumbai 2%. Urbanization negatively affects WQI, green spaces (NDVI) improve it. NDWI impacts vary, being negative but positive Kolkata, Delhi. Welch's analysis variance (ANOVA) post hoc confirms WQI differences cities. These results highlight urgent need for sustainable infrastructure, increased pollutant-free waterbodies India.

Assessment of groundwater suitability for drinking and irrigation purposes with probable health threats in a semiarid river basin of South India

Water Environment Research, Journal Year: 2025, Volume and Issue: 97(2)

Published: Feb. 1, 2025

In the semiarid river basin of south India, present study focuses on appropriateness water for drinking and irrigation as well risks to human health posed by pollutants. A total 68 groundwater samples were evaluated consumption purposes. With a high electrical conductivity peaking at 3430 μS/cm an alkaline composition, has salinity poor quality. Durov's figure displays trend along dissolution or mixing line identifies geochemical facies samples. According quality indexes, majority are categorized unfit (26.47%), extremely bad (36.76%), (26.47%). elemental concentrations, data grouped into three clusters using hierarchical cluster analysis. geographical distribution, nitrate levels safe over about 320.25 km2 dangerous 121.10 km2, whereas fluoride 293.92 147.43 km2. About 50.65 14.70% samples, fell no restriction category irrigation, indicating acceptable standards. Low sodium in soils indicated parameters like SAR, %Na, PI, RSC, MR, KR; SAR values fall C2S1, C3S1, C4S1 categories. Doneen's diagram, 70.5% had PI >75, suitability; Wilcox diagram classified 22.05% excellent 69.11% good permissible irrigation. risk assessment, 75% babies, 63% children, teens, 54% adults have THI >1 fluoride. 45% newborns, 42% kids, teenagers, 29% nitrate. Infants, teenagers danger. order safeguard against nitrate, emphasizes necessity efficiently managing resources, lowering agricultural pollution, assuring clean water.
