Report
Summary
TAMS is comprised of 18 groundwater and soil vapor monitoring wells, 10 shallow soil vapor monitoring wells, and 11 air sparge wells. A Honeywell fuel release was discovered in 1999. In 2007, the City learned that the fuel release had extended near Taxiway C north of Terminal 3. In 2008, the City and Honeywell entered into a remediation agreement. The City was advised that future migration of the fuel release could create methane and fuel vapor, which would affect existing or future infrastructure and building safety. The City designed and installed TAMS wells between 2009 and 2011, and began monitoring the wells in 2012. In 2012, Honeywell began operating a biologically-enhanced soil vapor extraction remediation system in the area. The TAMS monitoring project will be used to test for fuel plume movement and a portable air sparge system may be used as an interim remedial measure if movement of the fuel plume is observed. Geosyntec will be responsible for monitoring the wells and providing expert data interpretation.
