Free Lead Testing

Most lead services were installed in homes built prior to 1926. There were also a small percentage of homes built between 1942 and 1947 that have lead service lines. These homes are at higher risk of lead leaching from the pipes. We offer free lead testing for these customers and help them to interpret the results of their tests. Eliminating these lead service lines is the best long-term solution to the problem of lead in drinking water.

Lead testing kits are available for customers at the customer service desk at:

1900 Rice St
Saint Paul MN, 55113
Monday - Friday from 8:00 am - 4:30 pm

For more information contact customer service at 651-266-6350.

If you live outside our service area, you can have your household water tested by a private laboratory. Contact the Minnesota Department of Health for a list of certified laboratories.
