LACA plans to conduct continued testing and demonstrations of cyanobacteria mitigation and remediation capabilities in 2023. The 2023 project plan expands our research beyond the hydrogen-peroxide algaecide mitigation capabilities that we implemented in 2022 (see our 2022 project results by clicking on this link).
The 2023 Cyanobacteria Mitigation & Remediation (CMR) Project includes both mitigation and remediation techniques for cyanobacteria control. LACA defines mitigation and remediation actions as follows:
- Mitigation: Capabilities, technologies, and techniques that are focused specifically on impacting the life-cycle of cyanobacteria cells. Algaecides and ultrasound techniques are LACA's primary mitigation interests. These techniques are intervention strategies with short-term effects that must be enacted almost continually during each recreational season. The desired effects of both algaecide and ultrasound technologies are observed quickly, often within 24 hours of initiation/application.
- Remediation: Capabilities, technologies, and techniques that are focused on reducing or eliminating energy sources that cyanobacteria cells feed on or consume. Phosphorous reduction techniques are LACA's primary remediation interests. Phosphorous reduction techniques are deterrence strategies with longer-term effects when applied in a layered approach to ensure internal and external phosphorous loads are controlled/eliminated. The desired effects of phosphorous reductions technologies are observed relatively quickly, often within weeks of initiation/application.
The Project Plan is outlined in the following sections of this web page. LACA will publish data updates regularly as we make our way through the 2023 recreational season. You can request up-to-date information or data downloads at anytime by reaching out to the LACA project managers at this link.
