PFAS cleanup site — Restorical Research
Kingsley Field
Klamath County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a facility using PFAS-containing firefighting foam predating 1986. Historical insurance policies issued during operations at this property and through 1986 could help fund the ongoing and future cleanup under Oregon DEQ oversight.

Kingsley Field has operated as a military airfield since the late 1920s — serving as a U.S. Navy air station during WWII, a USAF base from 1957, and an Air National Guard installation from 1981 onward. Decades of aqueous film-forming foam (AFFF) use for fire training and suppression have produced PFAS contamination in groundwater at concentrations up to approximately 400,000 ppt, with potential offsite migration toward private wells. Oregon DEQ and the National Guard Bureau have identified 10 Areas of Interest requiring Remedial Investigation/Feasibility Study for PFAS, and a January 2025 Record of Decision selected soil excavation with offsite disposal for conventional contamination at two additional sites — work that has not yet been executed. 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 Oregon — 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.

AFFF fire training and suppression activities at this military airfield, which has operated since the late 1920s as a Navy air station, USAF base, and Air National Guard installation, began decades before 1986 and produced PFAS contamination in groundwater at concentrations up to approximately 400,000 ppt with potential offsite migration. The remedial investigation and feasibility study across 10 Areas of Interest for PFAS, the soil excavation and offsite disposal directed by the January 2025 Record of Decision, and the long-term groundwater monitoring this property will require are costs this site still faces that historical pre-1986 carriers may be obligated to fund going forward.

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.
