Three Federal Way parks have arsenic and lead soil contamination from the former Asarco smelter in north Tacoma. This fall, we are cleaning up the worst of the contamination and putting up signs in places we can't do cleanup.
healthy actions to limit their exposure.
Adelaide and Heritage Woods ParksAt both parks, only one sample out of many had elevated arsenic and it was outside of the play area. We won't remove any soils, but we will use signs to let people know about how to limit exposure.
Contamination has been in the soil for decades--why put up signs now?In the summer of 2010, with new funding from a settlement with Asarco, we were able to include parks in the Soil Safety Program. Until then, we only had funding to work on school and childcare play areas.
We spend the next year doing soil sampling for arsenic and lead at park play areas throughout the Soil Safety Program service area. Once we got the results, we began working with park districts to plan cleanup work. The results also helped us figure out where parks should post signs.
What about other parks in Federal Way?Most parks in Federal Way have arsenic and lead below state cleanup levels and do not need cleanup.
Open house events this summerWe are holding open houses at each of the three parks to provide more information about soil contamination and what we're doing about it. All events are on Wednesday evenings from 6:30 - 7:30 p.m.
