“…The loss of natural conditions of a river is mainly due to intricate anthropogenic aspects such as urban growth and development, agronomic and industrial actions ( Karunanidhi et al, 2020 ; Ogwueleka, 2015 ), constructions of the dams ( Wang et al, 2014 ), and natural activities like climatic circumstances, weathering processes, etc. ( Arya et al, 2019 ; Yegemova et al, 2018 ; Subramani et al, 2013 ). Metal contamination in river water is a worldwide environmental issue ( Tiwari et al, 2015 , Ali and Khan, 2018 ).…”

Twenty-two water samples from the Thirumanimuthar River course in southern India were collected before COVID-19 lockdown and during COVID-19 lockdown periods and were analyzed for microbiological parameters ( fecal coliform bacteria, total coliform bacteria, Escherichia coli, and fecal streptococci) and heavy metals (Fe, Mn, Zn, Cu, Cd, Ni, Pb and Cr). The lockdown has decreased microbial populations and heavy metals. Fe, Cu, Cd, Ni, Pb and Cr exceeded the drinking water limits, respectively, in 77%, 45%, 27%, 18%, 9% and 91% of the pre-lockdown samples. During the lockdown period, Fe, Cu and Cd concentrations in 23% and Cr in 50% of the samples exceeded the limits. Heavy Metal Pollution Index (PI) expressed that 27%, 64% and 9% of the pre-lockdown samples represented ‘low’, ‘medium’ and ‘high’ pollution categories, respectively, but 68% and 32% of the lockdown period samples represented ‘low’ and ‘medium’ categories, respectively. The Metal Index (MI) exposed that all samples of pre-lockdown were under the seriously affected category, whereas 54% and 46% of lockdown samples were under strongly and seriously affected categories, respectively. Health risk evaluation predicted that 95%, 91% and 86% of pre-lockdown samples and 45%, 36% and 33% of lockdown period samples were at risk among children, teenagers and adults, respectively. As there is no integrated study on river water quality of COVID-19 lockdown this work is uniquely carried out by combining heavy metal pollution, microbial contamination and human health risk evaluation.

“…In general, the hydrochemical characteristics of groundwater account for the quality of groundwater. Various geogenic factors, such as solute aqueous phase interactions and ion exchange processes, that occur in groundwater are largely responsible for the quality of groundwater (Arya et al 2019 ). The quality is further altered by climatic factors to some extent (e.g., recharge from increased rainfall) and ongoing anthropogenic factors.…”

“…Three articles refer to this topic and the paper of Arya et al (2019) evaluated health risk from rural drinking water supply by using inverse mass balance modelling (NETPATH code) in Vattamalaikarai River basin of south India. The calculated HQ values highlighted more risk for children and suggested effective remedial measures such as construction of artificial recharge structures to reduce the excess fluoride.…”

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. Faizal Khan et al. (2020) reported about the mixing of seawater and
