What's in Your Drinking Water? A Domestic Well Water Sampling Program

Drinking water from domestic wells that have not been tested for contaminants since initial construction may be a risk to health. One agency implemented a one-time Domestic Well Water Sampling program to provide well owners with free water quality analysis. Find out how the results can inform efforts to outreach and education, measure impacts of onsite wastewater treatment systems on groundwater and surface water, and be used to map constituent levels, and identify and map plumes.

Viruses in Groundwater Drinking Water Sources

This study involved conducting virus monitoring on a set of representative public water supply wells and evaluating the association between source water virus occurrence and community acute gastrointestinal illness incident rates. Find out how the results help predict which sources are most likely to be contaminated and identify critical factors that contribute to the protection of drinking water sources. Come away equipped to use this assessment tool and associated strategies for implementation.

The Drinking Water Treatment Partnership Project

The Drinking Water Treatment Partnership Project addresses the need for clean drinking water in low-income mobile home parks located throughout Eastern Coachella Valley, CA. This project funds and oversees the installation of water treatment systems (reverse osmosis units) that reduce arsenic and fluoride levels in the drinking water to safe levels. Other jurisdictions can make a difference similarly by working with local groups and non-profits that can address the need to remedy water quality issues for small water systems.

Swimming Pool Regulations: Both Sides of the Cyanuric Acid Stabilizer Debate

The Model Aquatic Health Code is published, but many in industry and public health think that the code did not set the correct limits for cyanuric acid. Some believe it is too restrictive and others believe it is not restrictive enough. This presentation is intended to provide you with the information you need to join the debate in the Conference of the Model Aquatic Health Code to help provide reasonable limits for cyanuric acid that are protective of public health.
