Drinking groundwater is a significant pathway for human exposure to heavy metals. To evaluate the health effect of some heavy metals ingestion through the groundwater drinking pathway, the authors collected 35 groundwater samples from the drinking water wells of local residents and the exploitation wells of waterworks in Baotou, China. The monitoring results indicate that the groundwater had been polluted by heavy metals in some regions of the study area. A health risk assessment model derived from the U.S.
Chronic exposure to inorganic arsenic leads to an increased risk of cancer. A biological measurement was conducted in 153 private well owners and their families consuming water contaminated by inorganic arsenic at concentrations that straddle 10 μg/L.
The aim of the study described in this article was to assess the physicochemical quality of water resources in Isfahan province, located in the central part of Iran, from June to November 2012. Comparison of the results with the acceptable limits recommended by the World Health Organization (WHO) for drinking water showed that nitrate, chloride, iron, and fluoride concentrations exceeded the maximum acceptable level in 12.3%, 9.2%, 6.8%, and 1.5% of samples, respectively.
EPA’s Office of Research and Development (ORD) and Office of Water invite you to a free webinar: Reduction of Lead in Drinking Water.
Identifying and solving lead issues from water systems with materials/device replacement in drinking water system configurations; presented by Michael R. Shock from EPA ORD.
In 2015, EPA’s Office of Research and Development and Office of Water will host monthly webinars to discuss challenges and treatment solutions for small drinking water and wastewater systems. For this webinar, Kevin Weiss (Office of Water) will present a compendium of performance data for facilities that blend during wet weather, followed by a presentation from Dan Murray (Office of Research and Development) on the evaluation of a decentralized, high-rate wastewater treatment plant for wet weather flows.
