Down on the Farm with PFAS: DOD Notifies Additional Agricultural Operations -- Total Nearing 4,000

Since 2021, the US Department of Defense (DOD) has notified nearly 4,000 agricultural operations of the potential for PFAS contamination in aquifers associated with military installations, adding nearly 400 new notifications in its most recent update.  DOD has been issuing such notifications since Congress included the requirement in section 335 of the FY21 National Defense Authorization Act (NDAA).  DOD must notify agricultural operations within one mile down gradient of military installations where PFAS associated with the bases has been detected in groundwater above advisory levels and “has been hydrologically linked to a local agricultural or drinking water source.”  The obligation applies to three PFAS compounds -- perfluorooctanoic acid (PFOA), perfluorooctane sulfonate (PFOS) and  perfluorobutanesulfonic acid (PFBS).  The advisory levels used to trigger the notices are 70 ppt individual or combined for PFOA and PFOS and 40 ppb for PFBS.

Many of the new notifications were issued in South Carolina, California, Washington and Nevada. 

"shall provide a any agricultural operation located within one mile down gradient of a military installation or National Guard facility where covered PFAS (1) has been detected in groundwater; (2) has been hydrologically linked to a local agricultural or drinking water source, including a water well; and (3) is suspected to be, or known to be, the result of the use of PFAS at an installation of the Department of Defense located in the United States or State-owned facility of the National Guard.
