WHICH WATER QUALITY TESTS DO I NEED?
There are many possible contaminants of water. Tests vary in price from a few dollars to several hundred dollars. Therefore, test only for likely contaminants - based on sensory clues and location hazards - and indicators of contamination.

The frequency of testing varies with each contaminant. Bacteria and nitrate tests should be performed yearly. These materials indicate that a larger problem may exist. Test should also be done any time a change in water color, odor or taste are noticed, when plumbing has been changed, if flooding has occurred near the well, or there has been reoccurring human or livestock disease that could be waterborne.
