NMED News:
 
The New Mexico Environment Department issued a few of the recent project activities on the Kirtland Air Force Base clean up of a decades-old jet fuel spill:
  • Drilling of 16 new groundwater monitoring wells was completed in early June. The analytical results from the new wells show that ethylene dibromide (EDB) in the shallow and intermediate zones is not migrating toward the Kirtland-3 and Ridgecrest-3 drinking water wells. The new monitoring wells are also defining the vertical extent of EDB contamination in the aquifer.  
  • The first extraction well designed to remove contaminated water and collapse the EDB plume was completed June 4. So far, it has extracted more than 60,000 gallons of groundwater that will be treated and used for irrigation at the Kirtland Air Force Base (KAFB) golf course.
  • Soil vapor rebound and bio-respiration testing began in April and will be completed in early July. Test results identified hotspots on base near the spill area that need further soil vapor extraction, as well as areas with significant microbiological activity that may be suitable for bio-venting that enhances biodegradation of the hydrocarbon contaminants.  
  • Laboratory treatability studies for the light, non-aqueous phase liquid (LNAPL) are complete. Options to scale up treatability studies to a pilot field test level are being evaluated.
 
Next public meeting: Thursday, July 23

  • Poster session starts at 5:30 p.m.
  • Presentation scheduled for 6 p.m., with questions/answers 6:30-8 p.m.
