Dry Cleaner cleanup site — Restorical Research

Preliminary Site-Specific Analysis

This property has a documented history as a dry cleaning facility going back to 1900. 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 has been in commercial laundry and dry-cleaning use since as early as 1900, with over a century of operations documented through Phase I and Phase II Environmental Site Assessments. Chlorinated solvents — including tetrachloroethylene (PCE), trichloroethylene (TCE), cis-1,2-dichloroethylene, and vinyl chloride — have been confirmed in groundwater at concentrations far exceeding Wisconsin DNR Enforcement Standards, with PCE detected at more than 300 times and vinyl chloride at more than 1,000 times their respective standards. The site is an active Wisconsin DNR Environmental Remediation Program case, with a responsible party designation issued in late 2025 and investigation work underway. 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.

Dry-cleaning and commercial laundry operations at this property began as early as 1900, placing over eight decades of chlorinated-solvent use in the years before 1986. The ongoing Wisconsin DNR Environmental Remediation Program investigation — along with the remediation, long-term groundwater monitoring, and NR 700 compliance work still ahead at a site where multiple compounds exceed enforcement standards by orders of magnitude — represents substantial future costs that insurance carriers from those pre-1986 operating years 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.
