ASTM D5472/D5472M

ASTM D5472/D5472M is the ASTM standard for determining specific capacity and estimating transmissivity at the control well, making it a focused reference for well performance evaluation. It is commonly used when a project needs a consistent, technical way to interpret pumping or aquifer-response data from a control well. By supporting clearer comparison and more reliable field assessment, this standard helps users document hydraulic behavior with greater confidence.

Overview of ASTM D5472/D5472M

ASTM D5472/D5472M, Standard Practice for Determining Specific Capacity and Estimating Transmissivity at the Control Well, provides a structured practice for evaluating well data in a controlled setting. The standard is centered on two related measures: specific capacity and transmissivity estimation at the control well. That makes it relevant for technical review, field interpretation, and standardized reporting where consistent methodology is important. As an ASTM standard, it supports more uniform engineering decisions and data comparison.

Common use cases of ASTM D5472/D5472M

This standard is commonly used in hydrogeologic and water-well testing workflows where control-well measurements are needed to characterize performance. It may be applied during pumping tests, field investigations, or other site assessments that rely on well response data. ASTM D5472/D5472M is especially useful when engineers or test operators need a repeatable basis for estimating transmissivity from observed control-well conditions. It supports documentation for evaluation, planning, and technical review of well behavior.

Benefits of using ASTM D5472/D5472M

Using ASTM D5472/D5472M can improve consistency in how specific capacity and transmissivity estimates are derived from control-well data. That helps reduce ambiguity in testing, supports better quality control, and makes results easier to compare across projects or crews. For procurement and compliance purposes, the standard provides a recognized technical reference that can strengthen reporting and reduce the risk of inconsistent interpretation. It is a practical tool for organizations that need dependable, standard-based well assessment.
