UI Water Quality

What is the latest information on the UI water testing and results?

  • UI water meets all EPA Safe Drinking water standards and testing.

 

What new technology or processes are being used?

  • Following a notification to campus about higher than normal THM levels in spring 2016, the UI began system flushing on Feb 7, 2016, which proved successful in immediately lowering the THM level in the water system. 
  • 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.
  • In October of 2015, the UI requested permission from the Board of Regents, State of Iowa, to proceed with project planning for a reverse osmosis filtration system to address high nitrate levels in the Iowa River. This system, which will also reduce the organic matter that causes the formation of TTHMs, is in the construction phase for installation and is expected to be complete spring 2018.

Which buildings are served by the UI water system?
The University Water System 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.

Do I need to filter my water?
There is nothing you need to do at this time, no additional filtering or water supply is necessary.

What agency sets the guidelines for safe drinking water standards and how often is testing conducted?
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 by UI Water Plant staff 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.
