Avoid yucky water!

Summer vacation is almost here and kids will be in the water. Protect yourself, your family and pets by avoiding contact with harmful algal blooms.

Harmful algal blooms can look like:

• white, blue or green spilled paint;
• green streaks on the surface of the water;
• green dots in the water or green globs on the surface of the water;
• pea soup.

Avoid and report suspected blooms

Because waterbodies may have harmful algal blooms that have not been reported to DEC, we recommend avoiding contact with floating mats, scum and discolored water.

If you suspect you have seen a harmful algal bloom, or you, your family, or pet has been in contact with a harmful algal bloom, please follow the instructions for reporting a bloom to DEC.

 If you see it, avoid it and report it!
