SOUTH PORTLAND (WGME) – Some of Maine’s waters are turning green.

Researchers say algae blooms are back along parts of the coast, and now they're worried about the health of Casco Bay.

At this point, experts don't know what's causing the green slime that's popping up in parts of Casco Bay.

CBS 13 spoke to Ivy Frignoca with Friends of Casco Bay, who says the algae blooms indicate high levels of nitrogen.

The algae use up all the oxygen in the area, and marine life like clams and worms are essentially suffocated.

When the algae showed up last year in South Portland and in Portland's Back Cove, they thought it was because of the drought and warmer water temperatures, but the presence of the algae blooms in late June of this year has them stumped.

The Friends of Casco Bay are trying to get to the bottom of it.

Right now, experts are doing DNA tests to determine exactly what type of species the algae is.

In the meantime, Friends of Casco Bay would like you to help them out. If you notice any green slime, you should contact them so they can continue to monitor it.
