Water Quality Assessment and Monitoring in Pakistan: A Comprehensive Review

Sustainability, Journal Year: 2023, Volume and Issue: 15(7), P. 6246 - 6246

Published: April 5, 2023

Water quality has been a major problem in Pakistan owing to mix of factors such as population expansion, industrial units urban areas, and agricultural activities. The purpose this research is conduct comprehensive evaluation water monitoring assessment Pakistan. article begins by examining the sources (i.e., surface water, groundwater, rainwater). paper then discusses methods used researchers for assessment, including chemical, physical, biological methods. It determined that certain regions Pakistan, concentration arsenic present groundwater exceeds national international prescribed maximum limits. range concentrations Punjab province can vary from 10 200 μg/L, while higher up 1400 μg/L have recorded Sindh. In province, fluoride 0.5 30 mg/L, Sindh, levels reach 18 mg/L. addition, some talked about bacteria. A 2017 study found fecal coliform different cities surpassed limits were high 1100 CFU/100 mL. Additionally, natural geological formations salinity areas contribute contamination water. effect pollution on public health potential cause harm. critical investigate creative strategies improving quality, it necessary make investments development, which could include implementation sophisticated technologies conception new treatment processes. review performed facilitates an understanding current types magnitudes contaminants sources. Subsequently, emphasizes deficiencies challenges existing frameworks provides suggestions them. This also significant benefit all stakeholders involved ensuring clean safe human consumption other purposes policymakers, managers, researchers, stakeholders.

Major ion hydrogeochemistry and health risk of groundwater nitrate in selected rural areas of the Guanzhong Basin, China

Human and Ecological Risk Assessment An International Journal, Journal Year: 2023, Volume and Issue: 29(3-4), P. 701 - 727

Published: Jan. 4, 2023

In this study, the hydrochemical characteristics of groundwater were assessed based on 64 shallow samples collected in Guanzhong Basin, China, and health risk nitrate (NO3-) drinking water was assessed. addition, spatial distributions major quality indicators investigated, while bivariate plots, saturation index, stable isotopes used to reveal processes controlling hydrogeochemistry. The results showed that study area mostly fresh water. However, maximum average NO3– concentrations 397.0 92.9 mg/L, respectively, indicating serious pollution. percolation contaminated river exhibited considerable impacts quality. Carbonate dissolution process groundwater, human activities responsible for high pollutants, especially NO3–. Evaporation fraction revealed by hydrogen oxygen ranged from 4 13% 11%, respectively.

Water Quality Index and Human Health Risk Assessment of Drinking Water in Selected Urban Areas of a Mega City

Toxics, Journal Year: 2023, Volume and Issue: 11(7), P. 577 - 577

Published: July 2, 2023

The present study was conducted to evaluate the quality of drinking water and assess potential health hazards due contaminants in selected urban areas Lahore, Pakistan. Water samples were collected from ten sites analyzed for different physico-chemical parameters including turbidity, color, pH, total dissolved solids (TDS), nitrates, fluoride, residual chlorine, hardness. Additionally, heavy metal (arsenic) microbial (E. coli) also determined samples. Drinking evaluation indices, index (WQI) biological human risk assessment (HHRA) estimated using analytical results target parameters. It found most that levels arsenic, TDS, chlorine higher than those recommended by National Environmental Quality Standard (NEQS) World Health Organization (WHO) guidelines. In addition parameters, content areas. Statistical analysis indicated are significantly between sampling sites. WQI all unfit unsuitable (WQI > 100) purposes except Bhatti Gate Chota Gaon Shahdara with a 87 91, respectively. these had very poor rating.
