MAKAH RESERVATION WARMHOUSE BEACH DUMP

WA | EPA ID WAN001002857

Human exposure is NOT currently under control

About this site’s exposure pathways: As of June 2023, the Makah Reservation Warmhouse Beach Dump Superfund site is considered "Human Exposure Not Under Control (HENC)". The draft Remedial Investigation (RI) Report is nearly complete and will go to the Makah Tribe for 30-day review period on 6/9/23. Region 10 expects the RI Report to be completed by the end of July or August (depending on whether the Makah request an extension). The RI Report concludes that sufficient data has been collected to make a “not under control” determination for the Makah Reservation Warmhouse Beach Dump Superfund site. Unacceptable risk was identified for receptor populations in both the human health and ecological risk assessments and an evaluation will be completed in the FS and a Proposed Plan to identify and select a remedial alternative.

Data limitations: Proximity to a Superfund site boundary does not mean your property is contaminated. EPA site boundaries show the area designated for cleanup, not the full extent of contamination. Groundwater plumes can extend beyond site boundaries. This tool shows publicly available EPA federal data.
