Offsite migration studies were conducted to characterize the hydraulic properties and groundwater chemistry of confined aquifer systems within the Hanford Site. These studies support the recommendations in ERDA-1538 to provide input for hydrologic modeling of groundwater flow within the Hanford Site, to afford information concerning possible contamination of underlying confined aquifer systems and to make the results available to the public. This report presents analytical results and aquifer test procedures used in characterizing the Rattlesnake Ridge interbed at well 699-25-80. The overall close association in groundwater chemistries and presence of elevated nitrate levels suggest that the Rattlesnake Ridge interbed may be locally in communication with the overlying unconfined aquifer system. Other physical evidence which indicates a potential local communication with the unconfined aquifer system includes: favorable stratigraphic position; absence of the confining Elephant Mountain basalt in surrounding areas; and intersection of a recharge boundary during aquifer tests of well 699-25-80.
