Food, Water, & Air

Olmsted County's Environmental Health staff provides residents with a range of services to protect the public's health. We work with:

  • Business owners to identify and address health risks in public facilities. These include food service (restaurants, cafeterias, special event food stands, and others), lodging, public swimming pools, manufactured home parks, and campgrounds. Staff review plans for new facilities before construction.
  • Members of the public by examining foodborne illness reports, responding to complaints about public facilities and public health nuisance conditions, consulting on indoor air & vector-borne disease prevention, including Lyme Disease, and cleaning up former methamphetamine labs.
  • We offer testing services for drinking water and radon.

Radon Testing

Radon is the second leading cause of lung cancer in the US, and about half of Olmsted County homes have radon levels that exceed the EPA Action Level.

Olmsted County can loan you a radon testing kit.

You are borrowing the kit from Olmsted County. You are responsible to keep the kit away from moisture and electric or static shock. If the test kit or its components become damaged while the kit is in your possession, you will pay the cost of fixing the kit.

If you do not return the kit you will pay for the cost of the kit.
