The new Problem-Check testing package analyzes water for the 20 most common nuisance contaminants. This testing package was developed for people who are experiencing problems with iron. The water is analyzed for both total and dissolved iron as well as iron bacteria. Additionally, we look at other contaminants that cause aesthetic problems such as odor, taste and discoloration. These would include manganese, calcium, magnesium, sulfate, tannins and potassium in addition to other contaminants important to determining treatment options.
