LOOK OUT FOR
QL BLOC
A harmful algal bloom (HAB) is an overgrowth of algae in a
water body that could affect water quality and aquatic life.
Some HABs produced by bacteria can create toxins that may
also harm people, animals, and the local environment.

HOW TO IDENTIFY A HARMFUL ALGAL BLOOM


Algal blooms can make the water appear green, brown, gold, or red. They often produce
scum, mats, foam, or paint-like streaks in the water or clumps on the shore. However, only
professional water testing can confirm if HABs and toxins are present. State and local
governments often test water for bacteria or toxins to protect water quality as part of their
water quality standards program.
