Herbicide in Newton Lake for algae control

Originally from the Courier Post

COLLINGSWOOD — Camden County has turned to chemical warfare in its battle to clean up Newton Lake.

The county is using the herbicide Captain, a copper sulfate solution, in an effort to curb the growth of algae in the lake, said county spokesman Dan Keashen. A website for the product said water treated with the herbicide has “no drinking-water or fish-consumption restrictions.”

“The main reason we turned to that is (that) the algae is coming back at a fairly aggressive rate,” Keashen said Friday. “We have confidence that A, it’s safe, and B, that it will work.”

Previous cleanup efforts included installing five aerators to improve water flow and using a machine to skim mats of algae from the lake’s surface.
