13. ABSTRACT (Maximum 200 words)
Water samples from 44 monitoring wells at three military installations were analyzed for the high explosives TNT
and RDX using immunoassay test kits. The accuracy and precision of the kit determinations were compared with
results obtained using the RP-HPLC, EPA Method 8330. Most of the kits achieved a 50% relative percent differ-
ence criterion over 85% of the time. One of the kits failed this test over half the time. Careful consideration must
be given to interferences that may be present and unique for each application.
