Algal Bloom - Healthy Recreational Water Habits
Enjoying the outdoors is an important part of an active, healthy lifestyle. ADEQ recommends following these simple, healthy habits in waters with visible algae:
- STAY AWAY from algae and scum in the water – AND – keep children and pets away from algae in the water or on the shore.
- DO NOT DRINK or use this water for cooking.
