“…Mazari-Hiriart et al (2000) used groundwater bacterial indicators and pathogens and the relationship between water quality and diarrheal disease rates in Mexico City (Mexico) to suggest ways to improve the potential of environmental health indicators (EHI) by framing epidemiological data and the use of GIS. Viable counts, fecal coliforms, Vibrio cholera, total streptococci, sulfate-reducing bacteria, and Escherichia coli allowed indicating vulnerable zones to water quality deterioration in Tamil Nadu and Pondicherry coastal aquifers, South India (Keesari et al, 2015;Vasudevan et al, 2020). In the deeper part of these aquifers, sulfate-reducing bacteria's predominance supported the hypothesis of reducing conditions that may lead to possible arsenic contamination in groundwater (Keesari et al, 2015).…”

“…These results show a significant variation in groundwater mineralization, probably due to local processes. Very low to brackish TDS values were also found in groundwater from aquifers in large coastal cities worldwide (Keesari et al, 2015;Shi et al, 2018;Vasudevan et al, 2020).…”

“…The research paper of Vasudevan et al (2020) carried out the evaluation of microbial contamination in shallow groundwater along the coastal Tamil Nadu (south India). It inferred more microbial activity in residential areas, cultivated regions and around the landfill sites due to the leaching of sewage water and fertilizer runoffs.…”

BackgroundGroundwater pollution is a worldwide problem with significant effects on human health and environmental security. It requires an in-depth understanding as the access to safe drinking water is a fundamental human right. The inferior quality of potable water has been deteriorating the human health and affecting the sustainable development of society. Increased urbanization and population growth in many parts of the world have exacerbated contamination of groundwater, mainly through the misuse of groundwater assets and the discharge of domestic and industrial sewage into the groundwater system. Human health is susceptible to the exposure of metal/metalloid, even at trace level, because of its persistence in the environmental media and acute toxicity.This special issue ''Impact of Groundwater Contamination on Human Health'' is a compilation of new case studies about recent advances in ground-breaking research about groundwater characteristics and groundwater modelling in different parts of the world using multidisciplinary tools to evaluate the risk on human health as well as on agricultural activities from chemical compositions and radioactivity along with other cutting edge topics like waste water management as well as microbial and heavy metal contaminations. It contains 23 different research papers from five countries (China, India, Kazakhstan, Kuwait, and Malaysia) focussing on seven different topics: (1) Hydrogeochemistry, (2) Groundwater modelling, (3) Risk assessment, (4) Radioactivity, (5) Wastewater treatment, (6) Heavy metals contamination, and (7) Microbial contamination. This editorial briefly reviewed the papers that focussed on different topics of groundwater evaluation and characterization. HydrogeochemistrySix papers of this topic represent case studies of saline water intrusion along the coastal Tamil Nadu and Puducherry states of south India using hydro-chemical and statistical techniques.

Generally, the quality and availability of groundwater resources can be affected by urbanization. In this research, various impacts of urbanization on the height of the water table and quality of groundwater in an urban aquifer has been investigated for Zahedan city, Iran. The investigations indicated that the widespread use of wastewater discharge wells in the city area had increased the elevation of the water table by 2 to 6 meters and had reduced the salinity of shallow groundwater. The effluent in the city's sewage channel with high EC had no effect on the groundwater quality in the city due to the fact that the channel was cement-lined within the city area. Microbial surveys showed that elevated total coliforms were present in groundwater throughout the city area while fecal coliforms were only present at a limited number of sampling sites. In the central areas of the city, where the groundwater abstraction takes place at high rates from deep wells, the pollution was less. The wastewaters had high level of total coliform and fecal coliform contamination due to the discharge of domestic wastewater through wells and the dumping of solids wastes. The urban water supply network and water treatment plants samples were free of any microbial contamination. Finally, nitrate concentrations in the groundwater were high (27-392 mg/L) and in the wastewater were much higher (up to 600 mg/L).
