WATER SAFETY UPDATE – DO NOT DRINK ORDER LIFTED
On the morning of Saturday, July 12, the City of Mattoon, in coordination with the Illinois Environmental Protection Agency (IEPA), conducted water quality sampling. Test results received today show a decreased level of algal bloom neurotoxin at 0.252 parts per billion, which is now 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 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.
