Free Product Recovery and Removal

In cases where free product (also known as light, non-aqueous phase product) is present on the groundwater surface, FREY will immediately implement a free product recovery and removal program. The objective of the program is to reduce the potential for further impacts to groundwater, and to reduce the potential for further lateral and vertical migration of contaminants in groundwater.

Typically, the free product recovery and removal program consists of manual bailing of wells containing free product at a maximum frequency of once a month. In some cases, the mass of free product beneath a site is extensive enough to warrant installation of an automatic free product recovery system, which continually purges free product from wells. In either case, the collected free product is collected in DOT-approved 55-gallon drums or an appropriate aboveground tank, then profiled, manifested, transported and disposed of as a hazardous waste.
