Potentially Hazardous Substances
The use and handling of potentially hazardous substances at the Titan II Missile Sites was
investigated during the PA primarily through review of records on file at the McConnell AFB
Bioenvironmental Engineering (BEE) office. These records cover the period from 1975 to 1987
and consist of shop folders for each of the 18 deactivated Titan II Missile Sites, shop folders for
missile group support shops located at McConnell AFB, and a deactivation file. Substances
associated with the Titan II Missile Sites include PCBs (Aroclor 1254), hydrazine, UDMH,
N-nitrosodimethylamine (NDMA), N2O4, hydraulic fluid, diesel fuel, trifluoroacetic acid,
trichlorotrifluoroethane (Freon 113), carbon tetrachloride, Stoddard solvent, methylene chloride,
Perchloroethylene ( PCE is a metal degreaser), methyl ethyl ketone, lead, and toluene (ES,1994).

7.2.4 Site 5 Groundwater
Concentrations of TCE, arsenic, iron and manganese were detected in groundwater above PRGs
or RSK values at Site 5 and were evaluated in the HHRA. Several additional compounds were
carried through the HHRA as a result of the MDL being three orders of magnitude greater than
the screening value. Benzo(a)pyrene and dibenzo(a,h)anthracene are examples of compounds
that were carried through the HHRA as a result of the elevated MDL.
