Soil moisture studies based on wells at 32-49 coordinates

Estimation of natural ground water recharge for the performance assessment of a low-level waste disposal facility at the Hanford Site

“…Neutron probe data were also collected after the well casing was installed to measure volumetric water contents. These data were reported by Brownell (1971) and Routsen and Fecht (1979).…”

“…The volumetric water contents from well 32-49A and the 3H data from wells 32-49B, 32-49D, and 19-47B are plotted in Figure B.2. The 3H profiles were considered to be classic examples of vertical 3H distributions in undisturbed areas of the vadose zone at Hanford (Brownell 1971). The high surface values of 3H were thought to be influenced by the 3H concentration in recent precipitation that occurred prior to sampling.…”

“…The purpose of the closed-bottom lysimeter was "to demonstrate beyond all doubt whether or not meteoric water is percolating to the underground water from the surface at the 32-49 Hanford coordinates" (Brownell et al 1975). Isaacson et al (1974) and Brownell et al (1975) described the facility and its instrumentation, and presented data for the 1971-1972, 1972-1974water years. Last et al (1976 presented water content profiles based on neutron logs for the 1974-1975water years.…”

“…-The fourth well, number 32-49D, was drilled in June 1970, approximately 16.8 m south-southeast of well number 32-49A(Brownell 1971). This well was drilled from the ground surface to the water table, located approximately 95 m below the soil surface(Hsieh et al 1973).…”

“…The instruments were installed to measure temperature and matric potential gradients in the field. Well 32-49C was hand-augered and instrumented to a depth of approximately 4.4 m (Brownell 1971;Enfield and Hsieh 1971). Well 32-49D was drilled to the water table at 95 m and instrumented at intervals along the entire depth of the borehole ).…”
