Well Water in Washburn County: What to Test and Why

Groundwater in Washburn County contains manganese, arsenic, and chloride. Manganese is present at levels that exceed EPA health standards, while arsenic and chloride are detected but at lower concentrations that do not exceed those standards.

These contaminants come from the local rock underneath the county. Manganese and arsenic dissolve naturally into groundwater as water moves slowly through the mixed rock layers. Chloride can enter from road salt and other surface sources, but concentrations here remain modest.

Groundwater in this county is moderately hard, driven by calcium and magnesium from the surrounding rock. The mixed rock composition that makes up the local geology contributes these dissolved minerals as water passes through. This moderate hardness is common across wells throughout the county, and iron is also present at moderate levels from the same geological source.

Manganese shows up at levels above EPA health standards in wells across Washburn County. Exposure to manganese over time can affect how your nervous system works. Arsenic is also present in county groundwater at lower levels, and long-term exposure to arsenic raises health concerns. Testing your well is the only way to know what you are actually drinking.

The water in Washburn County is moderately hard, which means you may notice some white or chalky buildup on faucets and fixtures. Iron at moderate levels can cause reddish or brown staining on laundry, sinks, and shower walls. Hard water can also shorten the lifespan of water heaters and dishwashers over time. The good news is that sodium and sulfate are both very low, so you won't have salty-tasting water or other related concerns.

We recommend testing your well for manganese, arsenic, and bacteria. A comprehensive metals panel typically costs $200 to $400 and is the best way to find out exactly what is in your water. Every well is different, and your water could have higher or lower levels than what is common in the county. Water softeners or activated carbon filters can help treat the minerals and contaminants found in your specific well.
