Iron In Water can create major problems

The Cope Company Salt offers free iron testing to determine the level of iron in water you use everyday. If iron is present, we will add Morton’s Rust Raze™ to your system each time we deliver salt in order to deliver the highest quality of softened water to your facility.

Iron in any water can cause water to have a bad odor, cause reddish or brownish staining of appliances and also create a bad taste for drinking.  Usually there are no dangerous health affects associated to having iron in water, but it can be an inconvenience for facilities that employ large amounts of people.
