About This Item
ASTM D6029/D6029M is a technical standard for analytical procedures used to determine hydraulic properties of a confined aquifer and a leaky confining bed with negligible storage by the Hantush-Jacob method. It provides a consistent framework for interpreting aquifer test data when groundwater flow conditions involve a confined system and a confining layer that can transmit some water. This makes the standard useful for evaluating hydraulic behavior with greater consistency in planning, analysis, and reporting.
What is ASTM D6029/D6029M?
This standard practice defines analytical procedures for estimating hydraulic properties from aquifer-test data using the Hantush-Jacob method. In practical terms, ASTM D6029/D6029M is used when analyzing a confined aquifer system that includes a leaky confining bed with negligible storage. The document helps users apply a recognized approach to interpret drawdown behavior and derive hydraulic characteristics in a controlled, repeatable way. It is primarily a technical reference for groundwater testing and analysis.
Where is ASTM D6029/D6029M used?
ASTM D6029/D6029M is commonly used in hydrogeologic investigations where groundwater conditions need to be evaluated from test data. It is relevant for projects involving confined aquifers, leaky confining beds, and related pumping-test or analytical workflows. Engineers, geoscience professionals, and environmental specialists may use it when assessing subsurface water movement, supporting well and aquifer evaluations, or documenting hydraulic properties for design and review. The standard supports consistent analysis in technical work tied to groundwater systems.
Why is ASTM D6029/D6029M important?
This standard matters because it helps users apply a recognized analytical method with greater consistency when interpreting groundwater test results. ASTM D6029/D6029M supports more reliable comparison of hydraulic-property estimates, which can improve technical confidence in reporting and decision-making. For procurement, compliance, and project documentation, it provides a clear reference for the method used. That can help reduce ambiguity, improve repeatability, and support better quality control in groundwater analysis.
