Summary
Council member Thompson reported that the RAB has installed soil‑vapor extraction wells near Main Street, plans to inject a long‑lasting activated carbon product (described in meeting as 'plume stop'), and provided program spending and indoor air‑quality participation figures; council was told additional funds will likely be needed.
Sunset — Council member Thompson told the City Council on Feb. 3 that the Restoration Advisory Board (RAB) has moved from an aeration‑curtain remedy to soil‑vapor extraction wells on Main Street and is preparing to inject a long‑lasting liquid activated carbon product described during the meeting as "plume stop" into the subsurface to reduce contamination.
Thompson outlined program spending for two remediation areas and indoor air‑quality outreach results. During the discussion she cited large cumulative spending figures for the two areas (reported in the meeting as $41,000,911 in one instance and later as $41,911,178 in another). Thompson said the program’s remaining funds for one site are about $136,000 and for the other roughly $500,000 (as reported in the meeting), and that the RAB will need to solicit additional funds to continue work.
On indoor air quality, Thompson reported spending of $757,590 for the area and said outreach efforts using mailers and door hangers produced about a 77% participation/retention rate, with 193 residences allowing sampling; roughly 130 households either declined or had not replied.
Why it matters: The remediation work involves long‑term environmental cleanup and multi‑million‑dollar program expenditures; the council was alerted that available funds may be insufficient and further solicitation will be required. Thompson said the new in‑ground approach is intended to provide a longer‑term remedy for the plume.
Council members asked about visibility of the work, sampling results and next funding steps. Thompson said the RAB plans public comment opportunities on the injection plan and will seek further funding to sustain remediation and outreach.
