UI Drinking Water Quality
University of Iowa water meets all EPA Safe Drinking water standards and testing.
See the 2022 Consumer Confidence Water Quality Report. All samples were taken per their schedule and met all requirements for clean drinking water.
Water Production and Filtration
A combination of methods ensures the UI campus water meets all EPA requirements and is safe to drink. The Water Plant uses 3,800 MMBtu of steam and 2,200,000 kilowatt-hours of electricity to purify and distribute 900 million gallons of water annually.
Equipment
In 2016, the university installed a carbon filtration system at the Water Plant.
UI Water Plant began operating a new Reverse Osmosis unit on June 1, 2021.
UI drinking water will then be a 50-50 blend of water from our traditional treatment processes and water filtered through the Reverse Osmosis unit. The process was installed with the primary goal of enhancing the plant’s ability to remove nitrates from the water supply.
FAQs
UI water meets all EPA Safe Drinking water standards and testing.
- On March 28, 2016, a carbon filtration system was installed as an additional step in the water treatment process. Carbon filtration removes organic material from the water prior to chlorination, removing the constituents that produce THM. A similar carbon filtration method is used in the Iowa City Water Plant, where it was recently shown to also be effective in removing neonicotinoids, a popular farm pesticide, from drinking water.
- On June 1, 2021, the University of Iowa began using a reverse osmosis unit to filter water. UI drinking water is a 50-50 blend of water from our traditional treatment processes and water filtered through the RO unit.
The UI Water Plant provides drinking water for most buildings on the main UI campus in Iowa City, including UIHC, the Hawkeye Campus, and the medical research campus. It does not provide water to the UI Research Park, University Capitol Center, or those served by City of Iowa City water system.
No additional filtering or water supply is necessary.
The EPA establishes the Safe Drinking Water Standards and the Iowa DNR administers the Public Drinking Water Program in Iowa under delegation of authority from the EPA. Testing is conducted several times a year in various locations. A rolling year-long average of those results is used to determine compliance. Testing is done at the State Hygienic Lab.
