Update on Water Authority Activities and the Independent Conceptual Model and Plume Containment for the Kirtland Air Force Base (KAFB) Bulk Fuels Facility (BFF) Site
b
Water Authority staff continue to monitor corrective action activities at the KAFB BFF Site in conjunction with INTERA, Inc., as the Water Authority's independent contractor. In addition, the Water Authority continues to work with the U.S. Air Force Civil Engineering Center in San Antonio on a mutually acceptable contingency plan to implement in the event Water Authority production wells become imminently threatened. It is anticipated that a public review draft should be available by the end of June.
In January of this year, Water Authority staff tasked INTERA Inc. to develop a conceptual site model (CSM) using data collected by KAFB's contractor during the investigation of the contamination at the KAFB BFF Site. INTERA has identified data gaps that are critical to understand the full nature and extent of the contamination, which will be important in developing interim measures and ultimately a final remedy to clean up this site.
INTERA was also asked to develop a conceptual remediation plan to address the groundwater contamination at this site in response to inquiries from the public and public officials about the Water Authority's concept for preventing further migration of the plume and to protect the Ridgecrest wells. INTERA is working on a few conceptual remedies, but has prepared a simplified model showing that the downgradient dissolved phase ethylene dibromide (EDB) plume can be contained by extraction wells that will produce an amount of water that can be handled by the Water Authority's Southside Reuse System on a year round basis.
