The above graphic shows the decreasing EDB, or ethylene dibromide, concentrations in the Kirtland/Ridgecrest plume. The evidence of plume collapse and its decrease in mass is only within the pump and treat area for the past four years.

Modeling, before the pump and treat method, showed the projected collapse of the plume. The plume capture model currently confirms the collapse by pump and treat, as seen here.

• The next public meeting is scheduled for July 27, 2023, 5 - 7 p.m. This meeting will be held on Kirtland AFB at the BFF Water Treatment Facility. Attendees should access the base through the Ridgecrest Gate, located near the intersection Ridgecrest Dr. SE and Louisiana Blvd SE, which is just south of Gibson & Louisiana Blvd intersection.

The public meetings are an opportunity to learn about the work being performed to address and remove groundwater contamination caused by a historical leak at the old Base Bulk Fuels Facility. Air Force environmental experts explain clean-up activities and answer questions.
