Truesdale Lake  

South Salem, New York

Copper Sulfate Treatment June 28th

Allied Biological treated the lake with Copper Sulfate, an Algaecide, on Monday, June 28th. Swimming is prohibited for 24 hours after application.

Copper Sulfate is used to combat Algae growth (it does not kill weeds). Recently we have had an early outbreak of algae due to the decomposition of the Elodea weeds killed by the earlier Avast! treatment. Typically algae is a problem later in the summer so expect another Copper Sulfate treatment in August.

If you have any questions about Copper Sulfate or would like to read the Material Safety Data Sheet, see the Downloads section of this website.
