Testing soil, water & waste can be difficult and complex. DNR approved labs provide more reliable results. At least once every year DNR approved labs must pass tests from an independent company. The labs are given samples to analyze and report how much and what kind of substances are in them. Below is the percentage of acceptable results from DNR approved labs.
