You may have seen a lot of greenish scum floating on the water during your visit to a state beach in Iowa. The co-ordinator of the state beach testing program for the Iowa Department of Natural Resources, Mary Skopec, says they’ve seen a spike in blue-green algae in recent tests. She says it continues a trend they’ve seen through this summer.
Skopec says some heavy rains have been part of the reason for the increase in algae blooms.
Skopec says the algae will go away once the weather changes.
Until the blooms start to go away, Skopec says you should be on the lookout for beaches that have posted warnings.
