Industrial & Manufacturing cleanup site — Restorical Research

Preliminary Site-Specific Analysis

This property has a documented history as an industrial and manufacturing facility going back to 1956. 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 developed for industrial use in 1956 and has hosted metal plating and electrical assembly manufacturing since at least 1958, with large quantities of trichloroethylene (TCE) used as a degreasing solvent and PCB-containing hydraulic oils used extensively in on-site buildings. A 1991 Phase II Environmental Site Assessment documented historical TCE solvent releases beneath the facility, and subsequent investigation has revealed an off-site groundwater plume migrating westward through the dolomite bedrock aquifer toward the Rock River and the Watertown municipal airport property. A sump water carbon filtration system has discharged more than 2.2 million gallons of treated water to the Watertown wastewater treatment plant since 2006, and off-site bedrock monitoring wells installed at the airport property in 2023 continue to detect chlorinated volatile organic compounds. The site remains an active Wisconsin DNR Environmental Remediation Program case with semiannual groundwater monitoring and remediation ongoing. 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.

Industrial operations involving TCE solvent use and PCB-containing hydraulic oils began at this property in the late 1950s and continued through the pre-1986 period, with PCBs banned outright in 1979 and TCE releases confirmed beneath the facility from decades of degreasing activity. The extensive ongoing remediation — including carbon filtration treatment, off-site groundwater plume monitoring across the bedrock aquifer, and additional investigation at the airport property — represents substantial future costs that those historical pre-1986 carriers 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.
