Why is Copper Sulfate a Problem?-Water and Wastewater Treatment

It's only about 25% active, but of that, only 1/10 of it is biologically active. When you do the math, 0.6% of it is biologically active, and the rest of it is a heavy metal contaminant. Most of us don't want that in our soil; nor do we want it in our water plants and that's why copper sulfate is not being used nearly as much as it once was.
