Abstract

Excessive growths of algae can cause significant disruption of critical water resource usages including: drinking, irrigation, recreation as well as be aesthetically displeasing. Water resource managers are often compelled to take action to mitigate these nuisance algal infestations. Algaecides can be efficient and effective management options to rapidly suppress algal blooms and restore water usages. However, laboratory and field data are required to accurately predict responses to an application as well as potential risks to non-target organisms. Laboratory experiments were used to measure the responses of problematic algae to algaecide exposures and evaluate the margin of safety to sensitive, non-target organisms. These experiments allowed for prediction and translation of an effective exposure to a specific field situation. The formulation of a specific algaecide, water characteristics, and the distinct alga can influence an exposure and subsequent response. Data regarding efficient and effective use of algaecides can alleviate the obstructions incurred from algal infestations and restore critical water resource usages.
