13. ABSTRACT (Maximum 200 words)
These studies are the second part of a two-year project that examines decontaminating groundwater sampling
devices. In the first year, the efficiency of various decontamination protocols was tested using small test pieces
of materials that are commonly used in groundwater sampling devices. Those tests showed that a hot detergent
wash and rinse followed by hot air drying (105C) was the most effective decontamination protocol. In these
studies, two groundwater sampling devices, a bailer and a bladder pump, were used to sample groundwater
that was contaminated with either trichloroethylene (TCE), munitions, or pesticides. These studies showed that
a hot detergent wash and hot water rinse followed by hot air drying is an effective method for decontaminating
these sampling devices.
