Be on the lookout for blue-green algae in Illinois water

SPRINGFIELD, Ill. (WICS/WRSP) — Rising temperatures also mean more trips to the lake, river, and pools.

The Illinois Environmental Protection Agency and Department of Public Health are reminding residents that when they do go out to be on the lookout for blue-green algae.

Water conditions right now, and throughout the summer, are ideal for cyanobacteria growth.

Cyanobacteria are also known as blue-green algae.

The blue-green algae occur naturally in lakes, streams, and ponds.

Most algae blooms are harmless, but some can produce toxic chemicals.

Exposure to such algae can cause sickness or other health effects in people and pets.

Residents who plan to hang out in or on Illinois waters are advised to avoid contact with water that:

• Looks like spilled, green or blue-green paint;
• Has surface scums, mats, or films;
• Has a blue or green crust at the shoreline;
• Is discolored or has green-colored streaks; or
• Has greenish globs suspended in the water below the surface.

People should also keep pets out of the water if it contains a cyanobacteria bloom.
