Creating Online Septic System Owner's Guides

This free online webinar with discuss a new online tool available for anyone to develop customized septic system owner’s guides. With over 25% of the US population being served by septic systems and that percentage on the rise, the need for proper management is a key issue to accelerate adoption of current technologies and improve existing onsite wastewater treatment systems. This project provides an online vehicle for wastewater professionals to transform rural wastewater management by developing a customizable Community System Owner’s Guide (CSOG).

Health Risk Assessment Research on Heavy Metals Ingestion Through Groundwater Drinking Pathway for the Residents in Baotou, China

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.

Measurements of Arsenic in the Urine and Nails of Individuals Exposed to Low Concentrations of Arsenic in Drinking Water From Private Wells in a Rural Region of Québec, Canada

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.

Assessment of the Physicochemical Quality of Drinking Water Resources in the Central Part of Iran

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 Webinar: High-Rate Wastewater Treatment for Peak Wet Weather Flows

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.
