Wildfires don’t just burn farmland − they can contaminate the water farmers use to irrigate crops and support livestock

Just like fires can contaminate municipal water systems by melting pipes, farms’ and ranches’ water supply systems are at risk. A first-of-its-kind study after the Maui fires explores the harms.

Plastic pipes are polluting drinking water systems after wildfires – it’s a risk in urban fires, too

A new study shows how toxic chemicals like benzene are leaching into water systems after nearby fires. The pipes don’t have to burn – they just have to heat up.

Dangerous bacteria is showing up in school water systems, reminding all buildings closed for COVID‑19 to check the pipes

When water stagnates in pipes, harmful metals and bacteria can accumulate and make people sick. Buildings that were shut down for weeks during the pandemic may be at risk.

Wildfires can poison drinking water – here’s how communities can be better prepared

Buildings aren’t the only things at risk in wildfires. Recent disasters in California have left local water system contaminated with toxic chemicals afterward, slowing return and recovery.
Discolored water can be caused by heavy metals, such as iron or copper. Iron can also act as a nutrient for organisms to grow in the pipes. Kyungyeon Ra/Purdue University

The coronavirus pandemic might make buildings sick, too

Office buildings have been left mostly empty for weeks amid the coronavirus pandemic, leaving standing water in pipes where harmful organisms can grow. What happens when those buildings reopen?
