Drinking water

St. Louis’ water has been tested for toxic chemicals by the Missouri Department of Natural Resources over the past decade and found to be safe. But the new EPA rules would set higher safety standards, and St. Louis will be retested.

Nonpoint source pollution is the biggest threat to water quality today — but the Clean Water Act isn’t fully capable of tackling it, two Mizzou researchers say.

A cross-disciplinary study suggests the multiple laws and regulations designed to protect water aren’t working, and a new focus on drinking water can fix that.

The city will have to increase its testing and monitoring under the Safe Drinking Water Act.

The Natural Resources Defense Council estimates there are at least 330,000 lead pipes funneling tap water into Missouri homes and other buildings — the sixth-highest of any state in the nation.

St. Louis and EPA officials say the city’s water treatment system needs to be updated to continue to provide safe drinking water and withstand climate change. Leaders say they’ve identified more than $400 million worth of upgrades, including the removal of lead service lines that deliver water.

Public records obtained by researchers at Virginia Tech show the city of Quincy changed its water treatment processes in the months leading up to the Legionnaires’ disease outbreak, which may have allowed Legionella bacteria to multiply throughout the water system.

Last month, St. Louis University launched its interdisciplinary WATER Institute. Director Amanda Cox and Administrative Director Rachel Rimmerman join host Sarah Fenske to explain what it's focused on and describe some important water-related research already underway.
