In 1988 and 1989, Pacific Northwest Laboratory installed a multiport ground-water sampling system in well 699-43-42K drilled near the 216-B-3 Pond on the Hanford Site in southeastern Washington state. The multiport system will be used to evaluate methods for determining the vertical distribution of contaminants and hydraulic heads in ground water. This installation was in conjunction with a similar multiport installation near the 300 Area of the Hanford Site. Well 699-43-42K is adjacent to two Resource Conservation and Recovery Act (RCRA) ground-water monitoring wells, which will allow for a comparison of sampling intervals and head measurements between the multiport system and the RCRA monitoring wells. Eight sampling ports were installed in the upper unconfined aquifer by backfilling at depths of 161.1 ft, 174.1 ft, 187.1 ft, 201.17 ft, 217.2 ft, 230.2 ft, 243.2 ft, and 255.2 ft below land surface. However, because of damage to the casing during installation, only the top four ports should be used for pressure measurements and sampling until repairs occur. The locations of the sampling ports were determined by the hydrogeology of the area and the screened intervals of adjacent ground-water monitoring wells. 4 refs., 8 figs.
