Two weeks ago, the girls and I checked out Colegate Park, a fantastic space-themed playground out in University Place. I came home all jazzed up to write about it, only to find this article from the Washington State Department of Ecology, dated 2003.
Here's the part we're concerned with: "At four parks, the average arsenic for a play area was above the state cleanup level of 20 parts per million. The highest average arsenic for a play area was 46 parts per million at both Curran Apple Orchard and Colgate Park in University Place. (Average of 6 to 10 samples within each play area). "
