Dis­colored water occurring in Hillsdale College’s water systems the week of March 6 was due to non-harmful iron deposits, Board of Public Util­ities Director Mike Barber said.
“When a water system is shocked by tur­bu­lence, the iron can be loosened and put back into sus­pension,” Barber said in an email. “Staining could occur if the water was used for washing clothing.”
The system was flushed to reduce the impact of the iron deposits and help return the water to a normal color. Barber said the water was always within require­ments set by the Michigan Department of Envi­ron­mental Quality and that the water was not dan­gerous.
“Though there may be an unusual taste to the water due to the iron in sus­pension, there was never a danger to the pop­u­lation if con­sumed,” Barber said.
He added that running the tap will typ­i­cally clear the water of dis­col­oration and refresh the system, but that it took a long time to com­pletely purge the water because of how much water was affected.
