Groundwater contamination at the Broadway Street Corridor Superfund site was first identified in 1992. The project was added to the National Priorities List in 2018. Then, a few months ago, the EPA signed on to a four year contract to carry out a cleanup. Currently, it's identifying what contaminants are there and developing the best method of cleanup. Clara Copps is the remedial project manager for the EPA.

She says the current investigation phase is a lengthy process, but it's integral to making sure the contaminants can be removed.

We want to have, you know, really solid data and a good idea of what we're dealing with here. And part of that includes several rounds of monitoring and everything to be able to have a good data set.

Vertical aquifer tests involve drilling holes in the groundwater, extracting soil and water samples, and testing them for contaminants known as volatile organic compounds. This round of testing will continue until mid-September. Copps says the agency will test again in summer 2026 to look for seasonal trends or changes. Copps says it's expected to cost $4 million for the investigation. For the cleanup, the EPA would attempt to find the contamination responsible party and build them.

If one is not found, the EPA will cover the cost. The EPA has no suspected responsible parties at this time. Thomas Ouellette IPR news.
