Preliminary Site-Specific Analysis

This property has a documented history as an industrial and manufacturing 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 at the intersection of West National Avenue and South 6th Street in Milwaukee has a layered industrial history dating to at least 1900, with documented pre-1986 uses including chemical research and wholesale chemical production, photo-finishing operations with chemical tanks, and vehicle repair services spanning more than fifty years. Contamination from multiple sources has been confirmed: tetrachloroethylene (PCE) and trichloroethylene (TCE) in groundwater originating from an adjacent dry-cleaning facility that operated from 1952 to 1975, plus polycyclic aromatic hydrocarbons (PAHs), arsenic, and metals in historic fill material across the site. Sub-slab vapor sampling detected PCE at 1,160 µg/m³ — approaching the residential screening level — and the April 2025 hazardous substance discharge notification confirms both soil and groundwater contamination. The site is an active Wisconsin DNR Environmental Remediation Program case with semi-annual reporting underway and substantial investigation and remediation work ahead. 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 and commercial operations at this property — including chemical research, wholesale chemical production, photo-finishing with chemical tanks, and vehicle repair — date to at least 1900, and the adjacent dry-cleaning operation confirmed as a source of chlorinated solvent contamination ran from 1952 through 1975, meaning decades of contaminant releases occurred well before 1986. The ongoing groundwater investigation, vapor intrusion assessment, historic fill remediation, semi-annual monitoring, and additional work required to satisfy Wisconsin DNR Environmental Remediation Program closure standards represent substantial forward-looking cost obligations that 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.
