Department of Defense Activities Related to PFASs

In the webinar, DOD explained that their first priority at any site is to cut off the exposure as quickly as possible.  That means providing bottled water when there is contamination of the water supply.   Once exposure has been limited, then DOD can follow the normal clean up process under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), commonly known as Superfund.  This involves an initial assessment, prioritization, followed by an evaluation of feasible options, and finally a plan for remediation that is then carried out.  This is often a very lengthy process.  To assist them in their response, the DOD is conducting research on the fate and transport of these and related compounds, the biological impact, as well as treatment and remediation technology.   Some of the specific research activities were covered in the webinar.

Over $200 million has been spent already on these sites and final clean up costs could be $2 billion.  So far, the Department has been carrying out activities in response to these contamination incidents using existing funds borrowed from funding committed to other environmental projects.  Funding specifically authorized for addressing these contaminants will not be available until the FY19 budget, which has yet to be proposed or considered by Congress.

In near term  action in Congress, the National Defense Authorization Act currently under consideration in the Senate, includes a provision requiring the Centers for Disease Control and Prevention (CDC) to study the health impacts of the PFAS chemicals.
