Overview of Currently Used Database of Vadose Zone Hydraulic Properties
• CP-63883 provides the latest available internally consistent database of VZ hydraulic properties.
• Compilation based on laboratory measurements of hydraulic properties over past three decades.
• Not all laboratory data sets used due to perceived quality issues.
• The relative amounts of gravel, sand, and mud (silt and clay) impact the hydraulic property of a bulk sediment sample in a fundamental manner.
• Natural variability exists in gravel, sand, and mud content. It is therefore important to understand and quantify this spatial variability and uncertainty in VZ parameters for each HSU.

Assessment of Hydraulic Properties Data at WMA C and WMA A/AX
• Based on the sampling plans described in the current SAPs for boreholes around WMA C and A/AX, we will be analyzing about 27 to 30 samples for hydraulic properties from various depths.
• This is deemed adequate towards development of representative data set for this area.
• Will be able to estimate the variability and fit probability distribution function for uncertainty analyses.

• 6 boreholes planned at wells at 216-B-63
Recommendation:• Target 5 boreholes near B-
Farm (1 for B/BX/BY Tank Farm + 4 nearby planned boreholes for 216-B-63)
• Collect samples at high vertical resolution
• ~40 samples
