Why is Copper Sulfate a Problem?

Randy McIff:
My name is Randy McIff and I’m the Director of Water and Waste Water Treatment with ATS. I’ve been a water treater for over 30 years
and I’ve worked in the industrial and municipal sides of business both pre- and post-treatment. Why is copper sulfate a problem? Copper sulfate’s a problem because it’s very
inactive. It’s only about 25% active but of that 1/10
of it is biologically active and so when you do the math, .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 near
as much as it once was, and the plants that have used it in the past are actually being
visited by environmental organizations and asking them to clean things up. There are much better alternatives to just
plain old copper sulfate. Give us a call. We can tell you what some of those are.


  1. Yeah right, copper is bad and fluoride is good. The real problem is that copper cuts into the profits of these chlorine suppliers.

  2. Well, for swimming pools, copper sulphate at low concentrations is an effective and very cheap anti-algae treatment. But be careful, you really need to calculate the amount carefully, otherwise your hair will go green!
