The lake will be treated today this morning with copper and Pond Shade Aqua Blue. The treatment will begin in the deep area, near the dam. It should reach the shallow area about 2 hours after that, at which time we recommend no swimming for 2 hours. By this time, it should be close to 12:00 when lessons are done for today and we are heading to Erskine to cheer on our swimmers in the Championship Meet! Below is the information on this treatment.
If you have any questions on this treatment, please contact Alan Fedeli, email@example.com or any member of the environmental committee.
Copper Sulfate Treatment
We will be treating with Copper Sulfate via fan boat today. This is our traditional treatment that we have done every year to reduce the algae population to prevent a blue-green algae bloom. Swimming is not restricted, but we typically keep swimmers out of the water for an hour or two after the shallow water is treated.
What is copper sulfate?
Copper sulfate is an inorganic compound that combines sulfur with copper. It can kill bacteria, algae, roots, plants, snails, and fungi. The toxicity of copper sulfate depends on the copper content. Copper is an essential mineral. It can be found in the environment, foods, and water. Copper sulfate has been registered for use in pesticide products in the United States since 1956.
How does copper sulfate work?
Copper in copper sulfate binds to proteins in fungi and algae. This damages the cells causing them to leak and die. In snails, copper disrupts the normal function of the skin cells and enzymes.
The blue dye product is Pond Shade Aqua Blue, it is food grade and safe for humans and animals, and it can be seen at Upper Erskine where they have used it for six years. It creates a blue surface film that blocks UV rays and reduces the sunlight that algae need to bloom. This treatment is expected to reduce the number and frequency of copper sulfate treatments we will need for the rest of the swim season.
