High Concentrations of Arsenic In Minnesota Counties

Since 2008, the Minnesota Department of Health (MDH) has detected higher concentrations of arsenic in many of the state’s municipal water sources. The Wisconsin Department of Natural Resources has also reported significant arsenic levels in wells across the state. 

What Is Arsenic?

Arsenic, a chemical that naturally occurs in rocks and soil, dissolves into the groundwater, which then leaches into nearby well water sources—thereby entering a home’s drinking water supply.

This substance is commonly used in certain pesticides, wood treatments, and tobacco manufacturing. Industries like mining, for example, can also release more arsenic into the environment, which may end up in the water we drink, as well as the air we breathe.

Unlike other common contaminants found in Minnesota drinking water, such as manganese or chlorine that you can see or smell, arsenic is odorless and colorless. This makes it much more difficult to spot when it comes out of your tap. And because arsenic levels may vary between wells, your water may contain a higher level of arsenic than your neighbor or vice versa—even if you reside in a small area.

What Are Safe Levels of Arsenic in Water?

According to the Environmental Protection Agency (EPA), the maximum concentration of arsenic allowed in community water systems is 10 micrograms per liter (µg/L). However, the MDH reports that over 10% of private wells have higher levels of arsenic, with some reaching as high as 350 µg/L, and the average falling slightly below 50 µg/L. 

Regular testing is being conducted to detect higher amounts of arsenic. To find out the arsenic levels in your area, view the Minnesota private well map for current testing results.

Effects of Arsenic in Water

In its inorganic form, arsenic is toxic and may increase your risk of developing cancer, diabetes, or heart disease. Even if your water supply contains less, or equal to, the recommended EPA standard, experts suggest that consuming arsenic over an extended period of time may still put you at risk of serious health issues.
