Homeowners can have their well water tested for nitrates and other possible contaminants at the Wadena County Fair on both July 30 and 31.

Homeowners who rely on private wells for their drinking water supply should test for nitrates on a regular basis. Studies indicate that between five and 25 percent of the private wells have nitrate levels above the federal drinking water standard. Nitrates in drinking water have been shown to have serious health risks, especially for newborn infants.

Free nitrate testing clinics will be held at the fairgrounds from 2 to 6 p.m. on both Thursday July 30 and Friday July 31, 2009 in the New Ideas Building.

Samples are analyzed on the spot - the process usually takes less than five minutes - and results are given directly to the homeowner. In order to participate in the testing, homeowners must bring at least one-half cup of water in either a Whirl-Pak plastic bag or a Ziploc-type bag. In order to get a good sample, allow the water to run five to 10 minutes before filling the bag.
