Industrial & Manufacturing cleanup site — Restorical Research
Stangler Property
Watertown, Dodge County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as an industrial and manufacturing facility predating 1986. 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 was used for vehicle salvage and scrapyard operations, with leaded and unleaded gasoline contamination confirmed by a Phase II Environmental Site Assessment. The presence of leaded gasoline — phased out nationally in the mid-1980s — and weathered petroleum compounds establish that contaminating activity predates 1986. Groundwater sampling revealed concentrations of benzene, toluene, ethylbenzene, xylenes, and trimethylbenzenes far exceeding Wisconsin NR 140 Enforcement Standards, with toluene measured at 12,000 µg/L and total xylenes at 11,030 µg/L at one boring location. The site is an active Wisconsin DNR Environmental Remediation Program case, and a November 2025 determination that the Site Investigation Report was not approved confirms that additional work is required to define the full degree and extent of contamination. 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.

Vehicle salvage and scrapyard operations at this property handled petroleum products — including leaded gasoline, which was phased out nationally by the mid-1980s — and the presence of weathered petroleum compounds in soil and groundwater confirms that contaminating activity occurred before 1986. The additional site investigation required by the Wisconsin DNR Environmental Remediation Program to define the full degree and extent of contamination, the remediation necessary to address groundwater exceedances of NR 140 Enforcement Standards, and long-term compliance monitoring represent future costs that the historical pre-1986 carriers for the businesses that operated here 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. Restorical then manages the claim, including accounting, to ensure the cleanup is funded in a timely manner.

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.
