2022 Cyanobacteria Mitigation ProJECT

Lake Guard Oxy Product Information

Lake Guard®️ Oxy is manufactured by BlueGreen Water Technologies.  It is part of BlueGreen’s innovative line of Lake Guard®️ remedies designed to effectively mitigate/remediate algae and cyanobacterial blooms (blue-green algae) in lakes and oceans of any size within 24-48 hours or less. The formulations are based on tried-and-tested algaecides/cyanobacteriocides that are verified safe for both humans and the environment. The addition of a patented biodegradable coat simplifies administration, making the formulation buoyant and transportable by wind and current to affected regions of water bodies without human intervention. These formulations, used in conjunction with BlueGreen’s extensive and advanced data science capabilities, hold the key to solving a host of pervasive worldwide environmental problems.

The Lake Guard®️ Oxy formulation is NSF / ANSI / CAN 60 Certified, US EPA approved, and approved by the Virginia Department of Agriculture and Consumer Services (VDACS).  The product's effectiveness against Cyanobacteria is so high that only small quantities are needed to make a massive impact.

The active ingredient in Lake Guard®️ Oxy is sodium percarbonate (a chemical that has long been used safely as an algaecide/cyanobacteriocide).  This ingredient is fully approved for safety.  Upon contact with water, Lake Guard®️ Oxy releases hydrogen peroxide which immediately causes oxidative stress in any surrounding cyanobacterial populations, prompting an auto-catalytic cell-death cascade.  The by-products of this highly effective remedy — water and oxygen — are completely harmless to the surrounding environment.

LACA conducted extensive research over the past eight months on the use of hydrogen-peroxide products in freshwater lakes, rivers and reservoirs.  This research led us to BlueGreen Water Technologies, and we initiated dialogue with them in December 2021 concerning the use of their Lake Guard Oxy product at Lake Anna.  LACA reviewed a number of peer reviewed research and academic papers on hydrogen-peroxide products and attended multiple seminars (via Zoom and other web conferencing platforms) on Cyanobacteria mitigation and remediation approaches.  The most economical and lowest risk approach that we identified is the use of hydrogen-peroxide to control the growth of Cyanobacteria in Lake Anna.  Based on the research and science-based approach, LACA selected the BlueGreen Water Technologies product Lake Guard Oxy for our Cyanobacteria Mitigation Program - 2022.  Please see our current Lake Guard Oxy Product Overview and our Library of Research Papers and Reports for additional details.

The Lake Guard Oxy Product was applied by SOLitude Lake Management, a licensed, certified applicator in Virginia.  The authorization to discharge this product in Lake Anna is granted under the General Permit issued under Virginia Administrative Code, 9VAC25-800-30.  SOLitude is the company that was contracted by Louisa County and the Lake Anna Advisory Committee (LAAC) to conduct an Algal Bloom Assessment and Recommendations for Part of Lake Anna in 2021-2022.  A copy of the LAAC Final Report is included in the Library, and you can click here to download a copy.
