Testing Biodegradability of Aqueous Film Forming Foam Formulations in an Aerobic Environment

Abstract

A test program was designed to assess aerobic biodegradability of seven aqueous film forming (AFFF) formulations in an aerobic environment. Six of the formulations were fluorine free and one was a fluorine-containing reference formulation (Buckeye). Of the fluorine free formulations, four were commercial foams and two were experimental foams supported by SERDP. Following the test plan outlined below, chemical oxygen demand (COD) present in the aerobic testing reactors was monitored after three hours of incubation and every seven days thereafter. Testing was complete in 28 days. Oxygen uptake volume and rate were monitored using an aerobic respirometer.
