Free and Online Water Quality Risk Tools

Thank you for visiting. In 2022, our U.S. Environmental Protection Agency (EPA) backed multi-university team released two tools that building owners, designers, utility and health officials can use to understand water safety in buildings. Links to both online tools are shown below.

• Invention 1: A water quality prediction tool: https://dsiweb.cse.msu.edu/index.php/time-series-analysis/plumbing-water-quality-tool/
• Invention 2: A QMRA decision support tool: https://dsiweb.cse.msu.edu/index.php/hypothesis-verification/4547-2/

Each tool allows for users to evaluate how their plumbing design and water use may impact chemical and microbiological water safety inside buildings. A variety of contaminants were included such as chemicals and biological organizations.

A tutorial is available for each tool on the Michigan State University access web portals.

These tools were developed using real-world monitoring data collected during the 4 year EPA backed National Priorities study. Additional information collected during the study helped inform the tools and scenarios available.

[This is U.S. taxpayer funded work and is a testament to how converging experts from multiple areas and organizations - in collaboration with industry, government, and the public - can make a difference.]

These tools allow for users to evaluate how plumbing design and water use may impact chemical and microbiological water safety inside buildings. Contaminants covered in these tools include Legionella spp., heterotrophic plate count (HPC), chlorine disinfectant, copper, iron, lead, nitrate, and total trihalomethane (TTHM) levels.
