Oversight committee says Knox Trail annual treatment report requires no formal comment

The 222 Main Street Oversight Committee reviewed the 2025 Knox Trail annual treatment-system report and an accompanying groundwater monitoring summary and found no immediate changes to recommend to EPA. Pam (committee member) told the committee the contractors and EPA appeared responsive to new data and that the report will be available publicly shortly.

The committee’s community-group representative said recent monitoring prompted questions about whether the plume model needs modification and whether an additional northern well may be required to pump-and-treat a newly observed flow path. "We have to take into account this new data that's showing up and maybe change our model a little bit," the representative said. The committee agreed not to submit formal comments on the annual treatment report this round but noted it will re-review the next annual submission.
