This property sits on a former landfill that received household and industrial waste beginning in the 1930s or earlier, following quarrying operations in the 1920s. Trichloroethylene (TCE) has been identified in sporadic pockets within the landfill material, and groundwater sampling in 2025 confirmed exceedances of Wisconsin NR 140 standards for multiple contaminants — including vinyl chloride at more than seventeen times the enforcement standard, along with benzene, naphthalene, arsenic, and barium above preventive action limits. Vapor intrusion impacts have also migrated to adjacent properties, and an active site investigation is underway under Wisconsin DNR Environmental Remediation Program oversight with multiple monitoring wells in place. That history could support an insurance coverage claim against the carriers who issued policies more than 40 years ago — coverage that could help fund the cleanup ahead.
Pre-1986 Commercial General Liability (CGL) policies were occurrence-based and did not contain an effective pollution exclusion in Wisconsin — and those policies may provide coverage that remains enforceable today. If contamination occurred while those policies were active, those historical insurance carriers may still have a legal obligation to fund the cleanup costs, even if the business closed or the property changed hands.
Landfilling operations at this property accepted household and industrial waste — including materials containing chlorinated solvents such as trichloroethylene — from the 1930s or earlier through subsequent decades, all well before 1986. The ongoing site investigation under Wisconsin DNR Environmental Remediation Program oversight, groundwater remediation needed to address vinyl chloride, benzene, naphthalene, arsenic, and barium exceedances of NR 140 standards across multiple monitoring wells, and vapor intrusion assessment extending to adjacent properties represent substantial future costs that Commercial General Liability carriers insuring the businesses that operated here before 1986 may be obligated to fund.
