Supply of safe, clean, and abundant water for drinking purposes is essential for good health. According to a United Nations report [1], about 884 million people are not getting clean water. The availability of safe drinking water is a growing key concern for the international community. In the context of population boost and water contamination [2,3], access to safe drinking water has become a global challenge in developing countries [4][5][6][7]. Water pollution has significant repercussions for the environment and human health [8]. It is also obvious that millions of people from poor countries die each year as a result of water-related preventable diseases [9,10].Different physical parameters such as pH, EC, and turbidity are important indicator of safe drinking water quality characteristics. Turbidity in water arises from the inclusion of silt, clay, and organic suspended particles. Turbidity of drinking water is related to its aesthetic as a qualitative parameter as it effects the visual acceptability of the water by the consumer. The pH of drinking water is a very important parameter that can have direct and indirect effects on quality. The pH of the water has a direct relationship with corrosiveness of the supply pipes and can increase the concentration of metals in the water. Direct exposure to water with extreme pH leads to irritation of the eyes, skin, and mucosal membranes [11].Electrical conductivity and total dissolved solids are secondary water quality parameters and represent the activity or the total amount of cations and anions present in the water. The major cations and anions in drinking water are Na , and these should Pol. J. Environ. Stud.

Our study aimed to investigate the concentration of various pollutants in water samples collected from student hostels of the University of the Punjab in Lahore, Pakistan, and the potential risk of these pollutants for health. A total of 18 samples from 12 different locations were assessed for physical, biological, and chemical contaminants using standard methods. The concentrations of arsenic (As) and coliform bacteria were above the international standards given by the World Health Organization (WHO). The range of As concentration was from 24.92 to 32.72 µg·L -1. Similarly, the two water samples showed bacterial contamination 38 MPN/100 mL and 21 MPN/100 mL -exceeding the standard value set by WHO (0 MPN/100 mL). We conclude that drinking water quality was poor, as is evident from the high concentration of As. Urgent measures are required to prevent such contamination and regular monitoring of drinking water quality in the study area.

“…In many studies where the reductive dissolution of FeOOH has been associated with high arsenic concentrations a moderate relationship between DOC, As and Fe is observed (Anawar et al, 2003;Ahmed et al, 2004;Halim et al, 2009). However, no correlation is found in the studied area (Table A1 of supplementary information).…”

High ammonium (NH4), arsenic (As) and boron (B) concentrations are found in aquifers worldwide and are often related to human activities. However, natural processes can also lead to groundwater quality problems. High NH4, As and B concentrations have been identified in the confined, deep portion of the Niebla-Posadas aquifer, which is near the Cobre Las Cruces (CLC) mining complex. The mine has implemented a Drainage and Reinjection System comprising two rings of wells around the open pit mine, were the internal ring drains and the external ring is used for water reinjection into the aquifer. Differentiating geogenic and anthropogenic sources and processes is therefore crucial to ensuring good management of groundwater in this sensitive area where groundwater is extensively used for agriculture, industry, mining and human supply. No NH4, As and B are found in the recharge area, but their concentrations increase with depth, salinity and residence time of water in the aquifer. The increased salinity down-flow is interpreted as the result of natural mixing between infiltrated meteoric water and the remains of connate waters (up to 8%) trapped within the pores. Ammonium and boron are interpreted as the result of marine solid organic matter degradation by the sulfate dissolved in the recharge water. The light δ(15)NNH4 values confirm that its origin is linked to marine organic matter. High arsenic concentrations in groundwater are interpreted as being derived from reductive dissolution of As-bearing goethite by dissolved organic matter. The lack of correlation between dissolved Fe and As is explained by the massive precipitation of siderite, which is abundantly found in the mineralization. Therefore, the presence of high arsenic, ammonium and boron concentrations is attributed to natural processes. Ammonium, arsenic, boron and salinity define three zones of groundwater quality: the first zone is close to the recharge area and contains water of sufficient quality for human drinking; the second zone is downflow and contains groundwater suitable for continuous irrigation but not drinkable due to high ammonium concentrations; and the third zone contains groundwater of elevated salinity (up to 5940 μS cm(-1)) and is not useable due to high ammonium, arsenic and boron concentrations.

“…6d) of (Ca 2+ + Mg 2+ ) versus HCO − 3 shows a moderately strong correlation among them, which further suggests that most parts of these solutes may be derived from carbonate mineral dissolution through microbial degradation of organic matter in the shallow aquifer. Moreover, the presence of organic matter in the shallow aquifer sediments of Bengal basin has been reported in several studies Halim et al 2008b). Microbial degradation of this organic matter could drive the mineral dissolution in the aquifer and may thereby enhance Ca 2+ and would probably include organic matter oxidation and root respiration, in addition to carbonate dissolution (Mukherjee et al 2007).…”

Probable sources and mechanisms of arsenic (As) release in shallow aquifer in eastern Bangladesh are evaluated using statistical analysis of groundwater compositions. Dissolved As in 39 samples ranged from 8.05 to 341.5 microg/L with an average of 95.14 microg/L. Ninety seven percent of wells exceed the WHO limit (10 microg/L) for safe drinking water. Principal component analysis is applied to reduce 16 measured compositional variables to five significant components (principal components--PCs) that explain 86.63% of the geochemical variance. Two component loadings, namely PC 1 and PC 2 (45.31% and 23.05%) indicate the natural processes within the aquifers in which organic matter is a key reactant in the weathering reactions. Four groups of wells are defined by the PCA and each group of wells represents distinct physicochemical characteristics. Among them, group III groundwater shows higher As concentration together with high concentrations of Fe, Mn, dissolved organic carbon, PO4(3-) and HCO3(-) than groups I and II. Speciation calculations suggest that only wells of group III are saturated with respect to siderite, and all groups of samples are supersaturated with respect of rhodochrosite. The relationship of As with these parameters in the different groups of wells of the study area suggests that reductive dissolution of Fe-Mn oxyhydroxides with microbially mediated degradation of organic matter is considered to be the dominant processes to release As in groundwater.
