This property has a documented history as a landfill going back to 1930. Historical insurance policies issued during those prior operations and through 1986 could help fund the multi-phase investigation and remediation work ahead under Wisconsin DNR oversight.
This property operated as a municipal solid waste landfill from the 1930s through 1982, receiving approximately 130,000 cubic yards of waste before being closed and capped in 1983. Annual groundwater monitoring in 2024 confirmed exceedances of Wisconsin DNR standards for benzene, vinyl chloride, and 1,2-dichloropropane in multiple monitoring wells and piezometers, with the groundwater plume migrating south toward Otter Creek. Methane migration to adjacent residential properties has also been documented, prompting installation of monitoring sensors and alarms in nearby residences and a landfill gas system designed to limit VOC and methane migration to neighboring properties and underlying groundwater. 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.
Why Historical Insurance Policies May Be Accessible
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.
Landfill operations at this site spanned roughly five decades before 1986, from the 1930s through closure in 1982, placing the entirety of waste disposal activity in the pre-1986 window. The ongoing groundwater monitoring, landfill gas management, methane mitigation at neighboring residences, and any future remediation required to address contaminant migration toward Otter Creek represent costs that those historical carriers may be obligated to fund.
