The 14-acre Wisconsin Public Service Corp. site is located in Green Bay, Wis. Currently, the site is used as WPSC corporate offices and as an employee parking lot. It is on the south bank of the East River near the confluence of the Fox River.
WPSC owned and operated the gas plant from the 1871 to 1947 in an area that was historically industrial. Processes included coal carbonization and carbureted water gas. WPSC still owns the site today, except for a small portion owned by a nearby hotel.

Contractors for site owner Integrys will be sampling for polycyclic aromatic hydrocarbons, or PAHs, along the Lower Fox River near the WPSC building in spring 2015. This will involve taking sediment samples from the river, surface-water samples from various locations on the river, soil samples using a machine that pulls up a “core” of soil, and groundwater samples from existing monitoring wells. In addition, some new temporary monitoring wells will be installed and vapors near corporate buildings will be sampled through small holes drilled in the ground up to 10 feet deep.
WPSC corporate employees, other nearby workers and river trail users may notice increased traffic, two or three contractors taking samples and some light equipment such as a pontoon boat, drill, and vapor sampling equipment the size of a football. EPA and Integrys will use the information collected to develop a document called a remedial investigation report, expected in 2017, which will describe PAH contamination in the area if any is found.
Under Wisconsin Department of Natural Resources oversight, various investigations have taken place since the 1984. In 2003, a cleanup occurred which included excavation, thermal treatment, and removal of about 26,000 tons of highly contaminated soil. Routine groundwater monitoring occurs semi-annually. Annual inspection of the cleaned-up area (the parking lot) shows that the site remains safe for employees and visitors to the WPSC office building.
