Resident urges soil and groundwater testing at DTG site after PFAS exceedances in Redmond supply wells
Summary
David Morton told the council Supply Wells 1 and 2 exceed the EPA PFOS limit (4 ppt), cited a 2013 fire at the DTG Recycle site as a plausible source, and asked staff to require soil and groundwater testing at the DTG site before the Evans Creek relocation project-disturbing soil in 2027—stressing that monitoring wells alone may not reveal contamination at the source.
At the May 5 City Council meeting, resident David Morton urged staff and council to require soil and groundwater testing at the DTG Recycle site (formerly Allwood Recycling) before the Evans Creek relocation project begins construction in 2027.
Morton said Supply Wells 1 and 2 are currently above the EPA maximum contaminant level of 4 parts per trillion for PFOS and identified the 2013 fire at the DTG site — where firefighting foam containing PFOS may have been discharged onto soil — as a plausible source because groundwater flows toward the city's supply wells. He said the DTG site itself has never been tested for PFAS.
Morton noted that the Committee of the Whole recently approved a $300,000 amendment to a Landau Associates contract to expand the groundwater aquifer monitoring network and that new monitoring wells (including Monitoring Well 25) will be sampled in summer 2026, but he said those samples alone will not determine whether soil at the DTG site is contaminated. He asked the council to direct staff to require direct testing at the DTG site prior to the Evans Creek relocation, arguing that relocation work could disturb contaminated soil.
What the meeting records show: Morton provided a detailed account tying elevated PFOS in supply wells to the DTG site and to a large 2013 firefighting foam use; he cited the $300,000 contract amendment for additional monitoring wells and requested staff-ordered testing at the DTG site. The transcript does not record a staff commitment to require such testing on May 5.
Next steps: Morton asked for a staff directive to require testing at the DTG site before construction; council action or staff response is not recorded in the meeting transcript.
