This video helps prepare water utility, emergency management, municipal, and elected officials for water system damage scenarios. Wildfires can damage water distribution system infrastructure both physically –and– chemically. Some damage may not be visible. Hazardous waste scale drinking water chemical contamination can be caused. This presentation does not cover all situations, but instead provides an introduction for the viewer. More information and help can be obtained by contacting the author.

Wildfire Water Contamination
The San Lorenzo Valley in Santa Cruz County has a partial Do Not Drink / Do Not Boil order in affect: is that order appropriate, what causes Wildfire water contamination, and what are good actions we as a community can take? September 6, 2020.

BYU Radio's Top of Mind with Julie Rose
When Buildings Stand Empty, Water Quality Suffers
While many of us have spent the last month staying home to help slow the spread of coronavirus, the water in our now underused or vacant schools and offices has been sitting stagnant in pipes. Researchers at Purdue University got an emergency grant from the National Science Foundation to find out what dangers lurk in that water and how to make sure it's safe as we begin slowly returning to work. May 8, 2020.

This video explains how to (1) calculate water volume inside a building water pipe, (2) measure water flowrate for a water outlet, (3) calculate flushing time for a water outlet, and (4) recognize the risks of estimating water volume, flowrates and flushing times without as-built drawings. The presenter was Elizabeth Mongagnino from Purdue University. More information can be found at PlumbingSafety.org. Questions can be directed to awhelton@purdue.edu.


This presentation is designed to help you better understand the value of flushing building water systems with fresh water. Viewers will learn how to: (1) Explain how flushing can improve water quality, (2) List the 3 goals of flushing, (3) Describe the difference between initial flushing and repeated flushing, (4) Explain the importance of flushing with fresh water, and (5) Outline potential complications with flushing. The presenter was Ms. Kyungyeon Ra from Purdue University. Questions can be directed to awhelton@purdue.edu.


Our team partnered with the University of Memphis and Michigan State University to conduct the largest and most intensive investigation of water quality over time and throughout a single house.  Our findings show the water quality of a home can differ in each room and change between seasons, challenging the assumption that the water in a public water system is the same as the water that passes through a building’s plumbing at any time of the year. We collected data 58 times at the house over the course of a year, logging more than 222,000 hours and 2.4 billion records. Read more: http://bit.ly/water-quality-study
