Water Testing

The City of North St. Paul tests residential water for lead and copper every three years. Results of the water testing from 2022 show that the 90th percentiles for both lead and copper are below the action limits. North St. Paul will continue with its current monitoring schedule, with its next round occurring in June-September of 2025 where the system will be required to collect 30 samples.

The Minnesota Department of Health encourages all public water supplies to actively provide educational material about reducing exposure to lead and/or copper in drinking water. Here is some helpful information from the Minnesota Department of Health

Copper in Drinking Water

Copper is a metal that occurs naturally and is used to make products, including parts for plumbing systems. Copper can get into your drinking water as the water passes through your household plumbing system. Your body needs some copper to stay healthy, but too much is harmful. Learn more here:

Lead in Drinking Water

Lead is a poisonous metal that can cause long-term health and behavioral problems. The main way to come in contact with lead in Minnesota is through lead-based paint in homes built before 1978. There are also many other ways to come in contact with lead, including through drinking water. Learn more here.
