In 2003, the City of Iowa City began treating its water in a state-of-the-art multi-source water purification facility. That facility provides the best water quality possible for Iowa City and University Heights residents. Iowa City's rolling (TTHM) average for 2016 was well below the Safe Drinking Water Standard at 32.9 parts per billion.
University officials say this is not an emergency, but notified the campus that their water system had exceeded the Environmental Protection Agency's Safe Drinking Water Standard of 80 parts per billion (ppb) Total Trihalomethanes (TTHM’s) in their drinking water.
