Addressing the jet fuel leak at Kirtland Air Force Base
The Water Authority works in cooperation with the United States Air Force, the New Mexico Environment Department (NMED), and our partner agencies (City of Albuquerque and Bernalillo County) to monitor the decades-old jet fuel leak that has contaminated groundwater beneath Kirtland Air Force Base and nearby neighborhoods. The leak site is a source-water protection priority for the Water Authority because of its proximity to drinking water supply wells. Fortunately, no drinking water wells have yet been affected by the leak.
The Water Authority voluntarily monitors groundwater near the leak site for several contaminants, including ethylene dibromide (EDB). The utility and its contractors also conduct regular reviews of publicly available NMED and Air Force records to monitor any migration of contamination toward down-gradient supply wells. This data is also used in developing conceptual models of the site by both the Water Authority and the Air Force. Such models integrate information on what contamination is present, where it can be found, and how it may (or may not) migrate through soil and water.
The fuel leak cleanup project is regulated by NMED under the federal Resource Conservation and Recovery Act (RCRA), which specifies a step-by-step Corrective Action Process for remediation of the spill by the Air Force (see graphic below).
The Water Authority’s Data Gap Groundwater Monitoring Well Project
UPDATE, APRIL 19, 2022–We are happy to announce that the installation of the Water Authority’s Data Gap Groundwater Monitoring Well is now complete. As of April 14, 2022, the drilling site located near Indiana St. and Kathryn Ave. has been cleared of all equipment and debris, leaving only the new well and its manhole cover in the street (see picture). We greatly appreciate the patience and cooperation of the neighborhood residents during the drilling process.
Water Authority staff and contractor reviews of the Air Force’s site characterization reports have identified a persistent data gap, or blind spot, regarding the extent of EDB migration toward Water Authority well fields to the north/northeast of the spill site (particularly at depth, well below the top of the water table). Because the Air Force has declined to install a monitoring well capable of filling this data gap, the Water Authority sought and received State capital outlay funds to do so on its own. Once completed, this project will significantly increase the utility’s ability to ensure the safety of nearby drinking water supply wells.

Samples Collected During Drilling
Push-ahead groundwater sampling will be conducted during drilling process at up to five depths, and an additional groundwater sample will be collected at the water table using a bailer. The purpose of this sampling is to obtain information about concentrations of EDB in groundwater during the drilling process within the “data gap” interval. The samples will be analyzed with results reported to the Water Authority within approximately 24 hours from when the lab receives the sample for the presence of EDB and the results used to inform the selection of the final well screened interval.

Ongoing Monitoring of Completed Data Gap Well
The Data Gap Well is sampled using two methods: (1) passive sampling using passive diffusion bag (PDB) samplers (for volatile organic compound [VOC] constituents) and dual membrane passive diffusion samplers (DMS) (for non-VOC constituents), and (2) a combination of low-flow sampling and purging three saturated well-casing volumes using a dedicated Bennett Pump.
|Date of Sample||Depth of Sample (feet below ground surface)||Sampling Method||Analytical Method (see Table 2 of the Work Plan)||Analyte||Result (Water Authority) (µg/L)||Result (KAFB Split Sample) (µg/L)|
|5/24/2022||572-592||PDB/DMB||8260B||2-Butanone (MEK)||0.47 J||<1.0|

PDB/DMB – passive diffusion bag/dual membrane bag
J – indicates that the analyte concentration is estimated and was detected between the method detection limit and reporting limit
NM – not measured
< – indicates that the analyte was not detected above the reporting limit
Analytes not detected above the method detection limit are not reported in this table, with the exception of EDB
