Industrial & Manufacturing cleanup site — Restorical Research
South Water Street Properties
Milwaukee, Milwaukee County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as an industrial and manufacturing facility going back to 1935. 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 industrial use since the late 1880s, with a succession of machine shop operations documented continuously from at least 1935 through 1982. Soil sampling at all four investigation locations exceeds Wisconsin NR 720 groundwater protection standards for metals including lead, arsenic, selenium, and mercury, while additional exceedances for benzene, tetrachloroethylene (PCE), PCBs, and multiple PAHs — including benzo(a)pyrene above non-industrial direct contact values — confirm widespread contamination consistent with decades of cutting oils, solvents, and hydraulic fluids. Groundwater was encountered at six to eight feet below ground surface, well within the zone of contaminated fill soils, and the property is directly adjacent to the Kinnickinnic River. Wisconsin DNR has designated a responsible party, approved a completed Site Investigation, and the case remains open under the Environmental Remediation Program with groundwater monitoring 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.

Machine shop operations at this property ran continuously from at least 1935 through 1982, introducing cutting oils, chlorinated solvents, PCBs, and heavy metals into the soil and shallow groundwater throughout a nearly century-long span of pre-1986 industrial activity. The future work required under the Wisconsin DNR's Environmental Remediation Program — including groundwater monitoring and remediation, cleanup of soils exceeding NR 720 standards for lead, arsenic, PCE, and PAHs, and protection of the adjacent Kinnickinnic River — represents substantial ongoing obligations that historical pre-1986 carriers may be required 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.
