Project Accomplishments in 2016

In 2016, NMED and the Air Force closed data gaps in the northwestern extent of the EDB plume, drilled and installed a fourth groundwater extraction well, conducted laboratory and field studies to identify technologies to remediate the source area, and made optimization to monitoring program for groundwater and soil vapor.

The 2017 Strategic Plan outlines strategies for remediation of this site.

(See the project HOME page and OUTREACH page for the most recent accomplishments)

Site Monitoring and Wellhead Protection (Strategy 1)

  • Drilled 2 new, nested groundwater monitoring wells to address a remaining data gap at the northwestern extent of the EDB plume.
  • Monthly testing of drinking water wells continued to show no detectable fuel contaminants.
  • Optimization of quarterly sampling for groundwater and soil vapor.
  • Completed a comprehensive surveying of all monitoring wells across KAFB to improve well coordinate survey data accuracy.
  • Conducted a validation study to evaluate the application of passive diffusion samplers in order to optimize sampling costs and waste management.

Source Area Remediation (Strategy 2)

  • Continued the soil vapor rebound and biorespiration testing.
  • Submitted a work plan for an In Situ Bioremediation Pilot Test to evaluate effectiveness of enhanced biodegradation of EDB.

Groundwater Remediation (Strategy 3)

  • Continued extraction and treatment of EDB-impacted groundwater as part of the EDB plume collapse interim measure. 
  • Submitted a work plan for the drilling of a 4th extraction well and expansion of the groundwater treatment system (GWTS).
  • Drilled a 4th extraction well for expansion of the EDB plume collapse IM.
  • Expanded the treatment capacity of the GWTS.
  • Treated water used for irrigation at the KAFB Golf Course.
  • Completed a gravity-fed injection pilot test at KAFB-7.
  • Draft Discharge Permit (DP)-1839 posted for public review and comment for gravity-fed injection at KAFB-7 and up to 4 additional injection wells for discharge of treated water.
  • Conducted field and laboratory sampling to troubleshoot fouling issues at the GWTS and extraction well KAFB-106233.

Public Outreach and Participation (Strategy 4)

  • Creation of an animation of the BFF project site and conceptual model.
  • NMED and KAFB held 3 joint public meetings in April, July, and November.
  • Participation in 12 presentations to Neighborhood Associations, university seminars, and professional societies.
  • Presented site information and data to Highland High School Advance Placement Chemistry and Environmental Science students.
  • Conducted a public field trip in April.
  • Hosted a booth at the International District Fair in September to allow direct access to NMED and Air Force experts.
  • KAFB completed public surveys and interviews to gauge interest in a possible a Restoration Advisory Board.
  • Hosted a technical workshop in November for the public, providing access to NMED and Air Force experts for detailed discussions of data and technical topics.
  • Development of gardening fact sheet and risk dashboard.

Project Accomplishments in 2015

In 2015, NMED and the Air Force closed data gaps in the northeastern extent of the EDB plume, began collapsing the EDB plume, and conducted laboratory and field studies to identify technologies to remediate the source area.

Site Monitoring and Wellhead Protection (Strategy 1)

  • Drilled and sampled 19 new groundwater monitoring wells and closed the northeastern extent of the EDB plume and defined the bottom of the plume.
  • Monthly testing of drinking water wells continued to show no detectable fuel contaminants.
  • Optimization of quarterly sampling and reporting.
  • Completed a synoptic water level measurement event across Kirtland AFB, the first of its kind.
  • Created a revised, stand-alone Executive Summary document for the quarterly monitoring reports.

Source Area Remediation (Strategy 2)

  • Completed the soil vapor rebound and biorespiration testing.
  • Developed a list of potentially suitable technologies for LNAPL interim measure.
  • Continued soil vapor extraction, removing approximately 770,000 gallons of fuel.

Groundwater Remediation (Strategy 3)

  • Installed first extraction well and began collapsing the EDB plume on June 6, 2015.
  • A temporary treatment system was constructed and produces water with no detectable EDB.
  • Treated water used for irrigation at the Kirtland AFB Golf Course.
  • Performed aquifer testing and computer modeling.
  • Two additional groundwater extraction wells and construction of a full-scale treatment system is on schedule for completion by December 31, 2015.
  • Evaluated multiple beneficial use options for treated groundwater, including aquifer recharge by infiltration galleries and injection well.
  • Created an independent panel of experts to review potential remediation technologies for LNAPL.
  • Completed microcosm laboratory testing of biodegradation of EDB and benzene.

Public Outreach and Participation (Strategy 4):

  • NMED and Kirtland AFB held 3 joint public meetings in March, July, and November.
  • Conducted two public field trips in April and October.
  • Participation in 10 presentations to Neighborhood Associations, university seminars, and professional societies.
  • Hosted a booth at the International District Fair in September to allow direct access to NMED and Air Force experts.
  • Kirtland AFB Initiated public surveys and interviews for updates to the community relations plan and to gauge interest in a possible a Restoration Advisory Board.
  • A Self-Guided Geologic Field Trip Guidebook will be published by December 2015.

 

Project Accomplishments in 2014

In 2014, NMED and the technical working groups made progress to identify and fill data gaps, and increase the robustness of interim corrective measures. The following progress was accomplished in 2014:

On-Site Activities

  • The soil vapor extraction system, which has already removed more than 500,000 gallons of fuel from the subsurface, was upgraded.
  • An air sparging pilot test well was drilled and put into operation.

Work Plans and Other Documents Submitted

  • A work plan to drill an additional 16 monitoring wells to fill data gaps in the horizontal and vertical plume definition was approved, and drilling commenced in early December 2014.
  • A work plan to drill the first groundwater extraction well and treatment system, which will begin to collapse the dissolved phase contamination plume and pull it away from the City of Albuquerque’s water supply wells, was recently approved.

Technical Work Groups:

  • Multidisciplinary working groups were established during the summer of 2014 to provide detailed review and analysis of highly technical issues pertaining to the investigation and cleanup of the Kirtland Air Force Base fuel spill. These working groups are comprised of experts from the entities with regulatory and public resource oversight for the project.

Public Outreach and Participation:

  • An e-mail Listserv to keep the public better informed of site developments and opportunities for involvement was created.
    Quarterly public meetings were modified to include poster sessions that allow members of the public to speak directly with NMED and Air Force technical experts.
  • A geological field trip was held to discuss the hydrogeology and geochemistry of the site with members of the public.
