Sources and Health Effects of Arsenic, Fluoride, and Nitrate in Water
Abstract: Arsenic, fluoride, and nitrate are major inorganic contaminants in water that pose significant risks to human health. These contaminants are introduced into water sources through both natural geological processes and human activities. Arsenic is primarily released from arsenic-bearing minerals through weathering, dissolution, and erosion, while human activities such as agriculture, mining, and fossil fuel combustion further enhance its presence in water. Fluoride contamination mainly results from the dissolution of fluoride-bearing …

Impact of Groundwater Pollution on Carcinogenic and Non-Carcinogenic Health Effects: A Review
Abstract: Groundwater is a critical source of drinking water in many regions worldwide, particularly in South and Southeast Asia, where dependence on untreated groundwater remains high. However, increasing groundwater contamination poses serious risks to human health. This review synthesizes recent peer-reviewed studies to examine the sources, distribution, and health impacts of major groundwater contaminants, with a focus on both carcinogenic and non-carcinogenic risks. Emphasis is placed on fluoride, nitrate, chromium, and …

Investigation of Pollution Status in River No. 2, Freetown, Sierra Leone, Using Physicochemical and Bacterial Indicators
Abstract: This study assessed the physicochemical and bacteriological quality of surface water in the River No. 2 watershed, Sierra Leone, through monthly sampling from March–August 2024 at upstream, midstream, and downstream sites. Analyses included temperature, turbidity, pH, electrical conductivity, total dissolved solids, ammonia, fluoride, sulfite, nitrate, lead, arsenic, chromium, and microbial indicators (Escherichia coli, fecal and non-fecal coliforms). Most physicochemical parameters met WHO drinking-water guidelines. pH (7.0–7.3), TDS (7–17 mg/L), turbidity …

Assessment of Physico-Chemical and Microbial Analyses of Hand Dug Wells in Makeni Town, Sierra Leone
Abstract: The various water samples were analysed for residual chlorine, ammonia, fluoride, nitrate, sulphite, lead, arsenic, chromium, and bicarbonate levels from January to August 2024. The bacteria contamination was investigated to determine the safety of the water for the consumption of human. The temperatures across the four wells ranged 27.3oC to 30.0oC, with and average values ranging from 27.94oC to 29.15oC. pH values were within the WHO recommended guidelines range of …

Ground Water Contamination in Shallow Aquifer of Punjab State With Special Reference to Uranium
Abstract: In Punjab State ground water is in general suitable for drinking uses except at few places in the southern and south western parts where it is not suitable due to high EC or high fluoride or nitrate or combination of all. Almost all ground waters are suitable for irrigation for growing crops like wheat, mustard, rice, barley and maize etc. However, at few places where EC of ground water goes …

Integrated Spatial and Statistical Assessment of Groundwater Quality in Rupbas Tehsil of Bharatpur, Rajasthan: A WQI-based Approach
Abstract: This study presents a comprehensive evaluation of groundwater quality in Rupbas Tehsil of Bharatpur District, Rajasthan, through the application of the Water Quality Index (WQI) and hydrogeochemical techniques. A total of 32 groundwater samples, 16 collected during the pre-monsoon and 16 during the post-monsoon seasons, were analyzed for key physicochemical parameters including pH, electrical conductivity (EC), total dissolved solids (TDS), dissolved oxygen (DO), oxidation-reduction potential (ORP), total hardness (TH), total …

Water Quality Testing of Yamuna River at Poiya Ghat (Vaikunth Dham/Swarg Dham), Agra: A Systems Study
Abstract: Since pre-historic times, river water has been used as a source of drinking water. River water is now a source of hydropower generation, irrigation, aquaculture, navigation, transportation, socioeconomic activities, human settlements and home for aquatic living forms. Apart from this, river water has very vital role in maintaining soil fertility, wildlife conservation and development of forest resources. Due to increase in industrialization, urbanization, mining, sewage disposal and rampant use of …

Polymer Chemistry Perspectives: Applying the Water Quality Index (WQI) for Groundwater Quality Assessment
Abstract: Through the utilization of polymers' special qualities, such as their capacity to concentrate analytes and their affinity for particular pollutants, we establish a strong framework for assessing groundwater quality. A more thorough understanding of groundwater contamination is made possible by the integration of polymer-based techniques with the WQI, empowering stakeholders to decide on remediation and water resource management strategies with knowledge. The quality of groundwater, especially shallow groundwater, is being …
