Soil testing reveals 2100 cubic yards of contaminated topsoil in Mount Norton project

The Cheshire Next Generation School Building Committee convened on April 25, 2025, to discuss the results of recent topsoil testing at the construction site, commonly referred to as "Mount Norton." The meeting focused on the classification and management of approximately 10,000 cubic yards of topsoil, which was analyzed for contamination.

The committee reviewed the findings from the testing agency, which categorized the soil into three classifications: clean, polluted, and contaminated. Clean soil can be removed from the site without additional costs, while polluted soil can be reused on-site if space allows. Contaminated soil, totaling about 2,100 cubic yards, must be disposed of properly according to EPA regulations.

The total cost for the soil testing amounted to $21,346.10, which included fees for sample collection and analysis. The committee noted that while clean soil was initially planned for removal, it was later determined that some of it exceeded acceptable levels of naturally occurring heavy metals. Consequently, the Connecticut Department of Energy and Environmental Protection (DEEP) must be notified before any clean soil can be moved off-site.

The committee discussed potential locations for the clean soil, including the North End, but found that they were not currently accepting additional fill. They are exploring other options within the town to find suitable sites for the clean soil.

Richard, a contractor involved in the project, is working on a plan to utilize as much of the polluted soil on-site as possible, particularly in non-structural areas. The committee aims to minimize the amount of contaminated soil that needs to be removed, thereby reducing costs and environmental impact.

In conclusion, the meeting highlighted the complexities of managing soil contamination at the construction site. The committee is actively collaborating with environmental agencies and contractors to ensure compliance with regulations while maximizing the reuse of materials on-site. Further discussions and planning will continue as they work towards resolving the soil management issues.
