Arsenic in Private Wells

Long-term exposure to arsenic, even at low levels, is associated with adverse health effects, including cancer of the bladder, lungs, skin, kidney, nasal passages, liver, and prostate. Other possible health effects include cardiovascular disease, developmental and reproductive effects, diabetes, and skin changes. The risks from exposure to arsenic depend on many factors, including the type of arsenic, the duration and level of exposure, and individual susceptibility, which can depend on things like age and genetics. These data are limited to new private wells constructed and tested August 2008 to December 2020. Therefore, these data are not representative of all private wells in Minnesota.
