Free water testing clinics will be available in early June. Washington County, in partnership with the Washington Conservation District and the Minnesota Department of Agriculture, will offer a free nitrate water-testing clinic 4-7 p.m., Tuesday, June 5 at Scandia City Hall. Nitrates are the most common contaminants in Minnesota’s groundwater. Experts recommend that private well owners who get their drinking water from wells should test their water regularly. To participate in the testing, collect at least one-half cup of water in a clean plastic or glass container. Run the water for 5-10 minutes before filling the container. Do this within 24 hours of the clinic and keep it refrigerated. Homeowners with water treatment equipment (other than a softener) should take two water samples – one before and one after the treatment process. This will determine if the system is working. Label the container with name, phone number, if the sample is before or after a treatment system, and a well identification number if more than one well is sampled. Samples will be analyzed on the spot – the process usually takes less than five minutes – and results will be given directly to the homeowner. For questions about the clinic or how to take a water sample, contact Wendy Griffin at 651-275-1136, Ext. 24.
