| contents | Mineral pollutants and coliform contamination in groundwater pose health risks to consumers: a spatiotemporal study in a mining-impacted area. Kazemi, Ali Esmaeilbeigi, Milad Nahvinia, Mohammad Javad Sahebi, Parisa Sahebi, Zahra Ahadi, Maral Asl, Ali Ghanavati Groundwater Humans Water Pollutants, Chemical Mining Enterobacteriaceae Iran Seasons Environmental Monitoring Spatio-Temporal Analysis Nitrates Child Risk Assessment Minerals Adult Phosphates Fluorides Water Microbiology The presence of mineral pollutants, combined with bacterial contamination, has significantly impacted groundwater quality and led to various health-related issues in mining-impacted areas. Therefore, we measured the concentration of fluoride (F), phosphate (PO), sulphate (SO), ammonium (NH), nitrate (NO), the total coliforms (TCs), and physiochemical characteristics in groundwater samples of South Khorasan, Eastern Iran. For this, we collected water samples from 100 wells in spring and autumn across this mining-impacted area. We then measured the concentrations of mineral pollutants and assessed their associated health risks to children and adults using the Environmental Protection Agency (EPA) models and spatiotemporal zoning maps in ArcGIS. The concentrations of PO, NH, SO, NO, and F were 0.70 ± 0.34, 0.82 ± 0.9, 175.45 ± 123, 15.26 ± 9.41, and 0.53 ± 0.68 mg/L in spring, and 0.71 ± 3.18, 4.68 ± 31, 306.72 ± 615.80, 19.30 ± 15.61, and 0.72 ± 0.65 mg/L in autumn, respectively. PO, NH, and SO exceeded both the World Health Organization (WHO) and EPA, but NO exceeded only EPA standards. TCs in both seasons exceeded the standards set by the EPA and WHO. The hazard quotient (HQ) values indicated non-carcinogenic risks for F⁻ and NO⁻, while posing no risks NH⁺ and PO⁻ in both adults and children during autumn and spring.Hazard index (HI) was greater than 1 for all minerals in both children and adults in autumn and spring. No correlation was observed between mineral compounds and TCs in the study area, yet the water samples were highly contaminated by coliform with a significant risk to adults and children. In essence, both mineral pollutants and TCs potentially pose serious risks to human, and more efforts are required to improve the quality of water in this area. |
