“…Therefore, it could also be attributed to the seepage of ESEs from the surface to the aquifer during monsoon season in the industrial areas. Similar studies from other parts of India have also reported that groundwater beneath industrial establishments is generally contaminated with heavy metals [51][52][53]. Although Fe is an essential element for human beings, a higher Fe concentration in drinking water can cause certain health impacts [54].…”

This paper presents the results of a study to assess the groundwater quality in an industrial town located in Punjab, India. A total of 99 samples of groundwater were analyzed during the premonsoon and postmonsoon periods of 2018, which revealed the presence of numerous environmentally sensitive elements (ESEs), namely, arsenic (As), aluminum (Al), chromium (Cr), iron (Fe), mercury (Hg), nickel (Ni), selenium (Se), and lead (Pb). Geographic information system (GIS)-based spatial interpolation showed higher contamination levels around the industrial areas and the drainage channel where industrial effluent is generally discharged. Further, groundwater quality was assessed using the heavy metal pollution index (HPI) and the metal index (MI), which indicated poor drinkability of the groundwater. Human exposure to groundwater contaminated with ESEs can pose serious health risks; therefore, noncarcinogenic and carcinogenic health risks due to presence of these elements were also evaluated. Reported health risks to humans from exposure to contaminated groundwater indicate the importance of regular monitoring of groundwater for ESEs vis-a-vis industrial effluent disposal practices.

“…This is dependent on the psychochemical parameters, where the solubility of the heavy metals increased with the decrease of pH values, which clarifies that the correlation occurs between heavy metals and physicochemical parameters. Fe is highly correlated with Mn, which suggests that they might come from a common source [ 79 ]. Fe and Mn can be released from geogenic sources as they are common elements in rocks and minerals [ 80 , 81 ].…”

Rapid urbanization and industrial development in the Langat Basin has disturbed the groundwater quality. The populations’ reliance on groundwater sources may induce possible risks to human health such as cancer and endocrine dysfunction. This study aims to determine the groundwater quality of an urbanized basin through 24 studied hydrochemical parameters from 45 groundwater samples obtained from 15 different sampling stations by employing integrated multivariate analysis. The abundance of the major ions was in the following order: bicarbonate (HCO3−) > chloride (Cl−) > sodium (Na+) > sulphate (SO42−) > calcium (Ca2+) > potassium (K+) > magnesium (Mg2+). Heavy metal dominance was in the following order: Fe > Mn > Zn > As > Hg > Pb > Ni > Cu > Cd > Se > Sr. Classification of the groundwater facies indicated that the studied groundwater belongs to the Na-Cl with saline water type and Na-HCO3 with mix water type characteristics. The saline water type characteristics are derived from agricultural activities, while the mixed water types occur from water–rock interaction. Multivariate analysis performance suggests that industrial, agricultural, and weathering activities have contributed to groundwater contamination. The study will help in the understanding of the groundwater quality issue and serve as a reference for other basins with similar characteristics.

“…Regular monitoring of all water resources and water points should be ensured to help determine problem regions, source of pollution and design a frame work of corrective plans. [17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33]…”

Anthropogenic activities are the major cause of environmental pollution. Industrialization, urbanization and agriculture activities are also causing huge troubles linked to human health in Pakistan. Heavy metals contamination has increased in drinking water because of urbanization and agricultural activities. Being one of the urbanized Cities, Dera Ghazi Khan has also been subjected to the hastily increasing harms of contamination. The respective study was planned to evaluate the heavy metals concentrations and identification of high risk areas for the inhabitants living in the city. Total ninety-six samples of drinking water were collected. TDS and EC were in the range of 1.48 to 8.412 mg/L and1.41 to 9.4µS/cm respectively. TSS was from 40 to 599 mg/L which were exceeding WHO guidelines in eight samples. Heavy metals such as Ni, Cr, Zn, Pb and Cd were measured through atomic absorption spectrophotometer. Zn average value was well within WHO standard while Pb was exceeded in thirty-nine samples. Cd was exceeded in fifteen samples; Cr and Ni were exceeded in eighteen samples. Sources of heavy metals identified as agricultural activities, domestic and commercial effluent. Ground water samples were found potable at some locations but at the same time pose serious threat to human health due to heavy metals above permissible limits.
