Landfill cleanup site — Restorical Research
City Of Marshfield Historic Fill Site
Marshfield, Wood County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a landfill going back to 1922. 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 served as a municipal dump from approximately 1922 through the 1940s, with historic newspaper records and aerial photographs from 1937–1938 confirming decades of waste disposal operations including domestic refuse collection, community cleanup events, and periodic burning. Groundwater sampling has revealed exceedances of Wisconsin NR 140 Enforcement Standards for vinyl chloride, dissolved arsenic, and multiple polycyclic aromatic hydrocarbons, and historic fill material has been confirmed extending beyond the property boundary onto an adjacent parcel. The Wisconsin DNR designated this a Historical Waste Site in 2023, and a Site Investigation Report submitted in March 2025 recommends additional groundwater monitoring before closure can be pursued. 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.

Waste disposal operations at this property — including domestic refuse collection, community cleanup events, and periodic burning — took place from approximately 1922 through the 1940s, placing all contaminating activities decades before 1986. The additional groundwater monitoring needed to track vinyl chloride, dissolved arsenic, and polycyclic aromatic hydrocarbon exceedances, further investigation of historic fill migration beyond the property boundary, and the remediation work required to achieve Wisconsin DNR closure under the site's Historical Waste Site designation represent future costs that carriers who insured the businesses operating here before 1986 may be obligated to fund.

Restorical's role is to locate viable historical policies, determine whether a successful coverage claim is possible, and assist our clients and their legal counsel to obtain insurance coverage.

The Restorical Proven Process

Task 1 — Research and Analysis
Restorical searches for viable historical insurance policies, researches the site history, analyzes the contamination impacts, and underwrites potential coverage — including a proprietary trigger analysis. At the end of Task 1, we provide a clear yes or no on whether viable insurance coverage exists to fund the cleanup, along with a strategy and recommendation specific to your situation, even if you are not the policyholder.
Task 2 — Coverage and Funding
When Task 1 confirms viable coverage, Restorical works with your legal counsel to tender the claim, negotiate and secure insurance coverage. Restorical will manage the ongoing claim process, including accounting to ensure the insurance companies are funding your remediation in a timely manner.
