Groundwater in Carver County contains iron, sulfate, and arsenic. Iron and sulfate exceed EPA health standards in this county, while arsenic is present but at levels that warrant monitoring.
These contaminants come from the rock layers beneath the county. Iron and sulfate dissolve naturally from minerals in the bedrock as water moves through the ground. Arsenic can also occur naturally in certain rock types in this region.
Groundwater in this county is very hard, driven mainly by calcium and magnesium dissolved from the rock below. The moderate iron content adds to the mineral character of the water. Very hard water is common across wells throughout Carver County.
Wells in Carver County contain iron and sulfate at levels that exceed EPA health standards. Iron can cause problems with how your body processes oxygen and can affect children's development. Sulfate in drinking water can upset your stomach and cause diarrhea, especially in infants and people with digestive issues.
The very hard water in this county's wells leaves stains on sinks, showers, and laundry that are hard to remove. You may see orange or brown streaks from iron buildup. Hard water also creates scale buildup inside pipes and appliances like water heaters and dishwashers, which can shorten how long they last and cost more to run.
We recommend testing your well water with a comprehensive panel since multiple contaminants are a concern in this county. Every well is different, and your water could have higher or lower levels than what is common here. Testing is the only way to know what is actually in your well so you can treat it properly. A comprehensive metals and minerals panel usually costs between two hundred and four hundred dollars. Treatment options like iron filters or water softeners can help address these concerns.
