The University of Arizona Cooperative Extension, Yavapai County is selling two types of water testing kits. They are: a Simple Five Parameter (pH, total alkalinity, total hardness, nitrite and nitrate) Test Strip Kit for $9.00 and an Arsenic Kit for $32.00 (both prices include shipping and handling). Both kits are self administered and require about 30 minutes of your time. The results are not "certified" but are reliable and will alert you the need for further testing.
