Mattoon, IL (WAND) – The City of Mattoon has reissued a do not drink order after a harmful algal bloom has made the water unsafe to drink.

The city said in a press release Tuesday evening that the algal bloom was found at 0.38 parts per billion level, above the advisory level of 0.3 parts per billion.

Mattoon lifted its previous do not drink order July 13 after lasting for over two days.

The city is unsure when the new order will be rescinded and is awaiting further information from the IEPA.
