Superfund Sites

CD1

Discuss the details of a particular Superfund site near your home.

There are many Superfund sites in the U.S. and some of you may be surprised to learn that there is probably a Superfund site located very close to where you live and you are not even aware of it.

There are several superfund sites here in Oklahoma. One particular site I’ve been looking at is the Tinker Air Force Base. Tinker AFB covers over 5000 acres & has close to 500 buildings on it. The contaminants of concern at the Site are chlorinated solvents and hexavalent chromium. Their main concerns were contamination of ground water & the removal of underground storage tanks. They have been cooperating with Oklahoma officials in ensuring the groundwater remains safe to the environment.

• The principal pollutants at the NPL Site are chlorinated solvents and hexavalent chromium.

• The shallow groundwater layers are contaminated with solvents and metals from past industrial activities.

• A Groundwater Treatment Plant (GWTP) that extracts contaminated groundwater from the Building 3001

Operable Unit has been in continuous operation since 1994.
