Summary:
Two non-intrusive, passive multilayer groundwater sampling devices are described which collect data simultaneously at small vertical intervals in the same well, without disturbing the geohydrological environment. One system uses membranes, the other uses remotely operated stainless steel cylinders connected in tandem. When used in several wells sufficient information is collected to allow a three dimensional characterization of contaminants and flow in the aquifer. The systems were used during field trials at Savannah River Laboratory in November 1991 and June 1992, and collected water quality and flow data over a 3 meter interval below the water table in each of two wells. Data from 1991 indicate weak vertical profiles in temperature, dissolved oxygen, and pH over the 3 m sampling interval. Other measurements indicated a relatively uniform horizontal specific discharge of about 6 cm/year over the same sampling interval. No statistically significant vertical structure was evident for discharge. This presentation will compare this information with data obtained from field trials in June 1992.
