The Mattoon do not drink water order has been lifted.
Water samples were taken Saturday morning by the City of Mattoon in coordination with the Illinois EPA. Test results received Sunday afternoon show a decreased level of algal bloom neurotoxin at 0.252 parts per billion. That level is BELOW the IEPA’s Do Not Drink advisory threshold of 0.3 parts per billion.
Following IEPA recommendations, the City has completed flushing of the Mattoon municipal water system. As a result, the Do Not Drink order is now LIFTED.
Before using tap water:
–Flush all cold-water lines for 5-10 minutes
–Discard all ice and replace water filters
–Flush hot water lines separately for 5-10 minutes
