Toxic algal blooms detected in Howard County’s Triadelphia Reservoir

A high concentration of blue-green algae has been detected in Triadelphia Reservoir, the Washington Suburban Sanitary Commission said Thursday. Blue-green algae, a type of algal bloom, can produce harmful chemicals called cyanotoxins that can cause severe illness in humans and animals if consumed or touched. Drinking water filtered from Triadelphia Reservoir, located along the Patuxent River in Howard and Montgomery counties, is not affected by the toxic bloom.
