Algae and Cyanotoxins

Erik Rosenfeldt, PhD, PE

Cyanotoxins are produced by certain types of algae, commonly referred to as Harmful Algae Blooms (HABs). When high levels of HABs exceed water quality standards, exposure to humans and pets can result in illness. Water utilities are facing increased threats of HABs and cyanotoxins in their drinking water supplies, particularly in the summer months. Algae-related toxins can cause taste and odor issues and, more importantly, result in shutdowns of water systems to protect public health.

Reducing HAB Risk in Drinking Water

Hazen adopts a holistic approach to reduce risk from HABs and cyanotoxins, which includes monitoring and managing contamination in source water, and treatment barriers in the plant. We deliver comprehensive solutions to assess and manage conditions in natural and man-made water resources, while engaging sustainable engineering and management practices to improve the ecological integrity of the systems used for drinking water as well as for recreational and ecological purposes.
