Soil Safety Program

Arsenic and lead in play-area soil can pose a risk to children. We provide free soil sampling and soil safety actions for play areas within the program service area (see map for boundary). We sample public and private schools, licensed childcares, parks, camps, and multi-family public housing.

Are you starting a new childcare facility?

Under WAC 110-300-0400, the Department of Children, Youth and Families (DCYF) requires childcare facilities located in Ecology’s Soil Safety Program Service Area to sign up for arsenic and lead soil evaluation as part of the licensing process. 

The Soil Safety Program Service Area is limited to Vashon-Maury Island in King County and western Pierce County. Ecology does not evaluate childcares in mainland King County, nor in Thurston County. A map of the current Soil Safety Program Service Area can be found below.

If you are opening a childcare, you can use this interactive map to find out if you are in the program service area. Follow the instructions below to learn what you need to do to satisfy the lead and arsenic evaluation agreement requirement:

  1. Enter your address into the address bar in the upper left of the map.

  2. Review the message box in the lower left of the map.

    • If your property is located within the Soil Safety Program Service Area, please contact for further assistance. 

    • If your property is not located within the Soil Safety Program Service Area, save a screenshot of the page, including the message box, and share with your DCYF licensing agent.
