Spring is an important time of year for people who rely on a private well for their drinking water supply. The groundwater which supplies your well starts as precipitation in the form of melting snow and spring rains. In the spring, precipitation recharges the groundwater supply.
You should test your well water any time you notice a sudden change in color, odor or taste. There are a number of contaminants for which well owners should consider testing. Some of these include human-related contaminants such as nitrate and pesticides or naturally occurring contaminants such as arsenic.
The Washburn County Extension Office has water test kits available for sale. The kits can be purchased Monday through Friday between the hours of 8:00 a.m. and 4:30 p.m.
