“…Anion chemistry (Table 3) showed a greater dominance of chloride varying signifcantly across the area. Chloride occurs in groundwater from numerous sources including minerals, sewage, and industrial efuents [19]. Te levels of chloride were well within the permissible limits except for locations P4, P8, and P10.…”

Groundwater sources provide an important supply of alternative drinking water in most urban areas in Malawi. This study was conducted to assess the quality of groundwater in Area 25, a typical urban residential area in Malawi. Samples were collected from wells and analyzed for physicochemical and bacteriological parameters following standard methods. Results were compared to Malawi Standards (MS) and World Health Organization (WHO) drinking water quality guidelines. The overall water quality index was computed to ascertain the general quality of the water. Levels of pH, phosphate, sulfate, arsenic, lead, and potassium were below the guideline limits while, electrical conductivity, total dissolved solids, chloride, fluoride, nitrate, total hardness, calcium, and magnesium were observed above permissible limits, posing a health risk to the residents. The quality index ranged from 22 (excellent quality) to 64 (Poor quality) with an average of 41 (good quality). Fecal coliforms were present in 70% of the sampled locations with an average of 7.9 cfu/100 ml. The presence of these bacteria presents a serious risk for waterborne disease outbreaks. This study, therefore, recommends the provision of basic treatment techniques to improve the quality of water in the area before consumption, regular monitoring of groundwater resources, and proper design and setting of septic systems.

“…Temperature of both types of samples was in the range of 14 0 C to 32 0 C with a mean value of 24 0 C and small value of 4 standard deviation. Temperature is the key parameter and control variable which affects other parameters such as EC,TDS, and Solubility of different substances both geogenic and anthropogenic (Doubi et al, 2021). Cool water is more palatable than warm water especially in hot days while in winter water is more suitable for drinking at room temperature.…”

The present study is about vast domain of water quality analysis, encompassing a comprehensive exploration of physical, chemical parameters and heavy metals i.e., Cadmium and lead, which determined the quality and composition of drinking water of 45 WASA filtration plants in Rawalpindi. All the physical parameters EC, TDS, salinity, and pH were calculated on site through field kits and chemical and ionic parameters were analyzed in the laboratory using various techniques of titrations and spectrophotometry. Water quality index was determined using all the parameters. Health risk assessment of heavy metals was done and Health Index for both children and adults were determined following the standard protocol of USEPA. For social and economic evaluation of plants interview was hold with the institute and a questionnaire survey was done to know the responses of public. Spatial distribution, variations of different parameters was shown in spatial maps made in ArcGIS by ESRI. Results showed elevated levels of lead and cadmium above the standards of WHO suggesting 21 % of plants are risky for public health. WQI results revealed that 40% of samples were of excellent quality and 13% showed very poor quality. Results of Ionic trends indicated high levels of Ca2+, HCO3- Mg2+ and Cl-. Cations show Ca2+ >Mg2+>Na+ while anions show HCO3->Cl->SO42->NO3>PO43- trend. From social survey it was found that there is contradiction between public perception and WASA operation. With overuse of water and growing population groundwater table is going down therefore water is supply twice a day for 4 hours. The findings illuminate the importance of continuous observance and systematic management of water systems. The study’s recommendations encompass a holistic monitoring approach, tailored treatment strategies, community empowerment, infrastructure upgrades, regulatory oversight, research-driven innovation, and interdisciplinary collaboration. Implementation of these strategies promises transformative outcomes, securing the purity and availability of water resources for a healthier and more prosperous future. In our role as custodians of this invaluable asset, it is our shared responsibility to safeguard its sanctity and sustain its vitality.
