  • Are copper-based algaecide products effective in reducing cyanobacteria growth?
  • Three copper-based algaecide products were investigated for use in a drinking water source to address cyanobacteria growth. Bench-scale experiments were used to determine the optimal dose of each product given Lake Rockwell’s indigenous population and reservoir-specific characteristics.
  • What are copper-based algaecides?
  • Copper-based algaecides evaluated included a copper salt (CuSulfate) and chelated copper formulations with (CuAdjuvant) and without an adjuvant (CuChelated).
  • Are copper-based algaecides safe?
  • There are many new and modified copper-based algaecides entering the market to meet the demand for mitigating cHABs. The EPA limits the maximum amount of copper (1 mg/L) that can be applied as the active ingredient as it is toxic to non-target aquatic organisms [ 4, 20 ].
  • How does Copper affect algaecide effectiveness?
  • When copper compounds are used as aquatic algaecides, the cupric ion is usually bound by chelators (e.g., ethanolamine or citrate) to prevent precipitation or complexation from ions in water, which could have influences on the algaecide effectiveness for controlling algal growth.
