ROCKTON (WREX) — The Illinois EPA found elevated metals in groundwater monitoring wells at the former Beloit Corporation Superfund Site in Rockton, next to Chemtool.

If you live in the Blackhawk neighborhood and use a private well, the Winnebago County Health Department and the Illinois Department of Public Health recommend you don't drink your water for drinking or cooking.

The groundwater monitoring wells aren't used as drinking water for the public and no metals found in the municipal water supply for the Village of Rockton which was tested on June 21, 2021.

The Illinois Department of Public Health expects that a majority of residents are not using their private well water as drinking water.

During the Beloit Corp Superfund Site Remedial Investigation, Illinois EPA funded the installation and maintenance of carbon filter treatment units for residences in the Blackhawk Acres Subdivision to ensure residents are not exposed to drinking water which may pose health risks.

A majority of those residences connected to the Village of Rockton community water supply and should no longer be using their private well water for drinking water. However, IDPH and WCHD will provide Illinois EPA with technical support and local information on private wells still being used by residents.

Of the 20 monitoring wells sampled, elevated levels of metals were identified in 16 wells. The detected metals included antimony, cadmium, chromium and nickel in groundwater monitoring wells.

While some metals are essential nutrients, exposure to high levels can cause a variety of health concerns depending on the metal. Health interpretation of results collected on private property will be provided by the Illinois Department of Public Health directly to property owners.

Illinois EPA has posted the final groundwater monitoring well sample data on the Agency’s website on both the Beloit Corporation and the Chemtool page.
