About This Item
ASTM D5270/D5270M is the ASTM standard that covers analytical procedures for determining transmissivity and storage coefficient of bounded, nonleaky, confined aquifers. It is used when groundwater professionals need a structured approach for evaluating aquifer response in controlled conditions. By defining a common practice for analysis, this standard helps support more consistent interpretation of test data, better comparisons between projects, and more reliable engineering decisions in hydrogeologic work.
What is ASTM D5270/D5270M?
ASTM D5270/D5270M is a standard practice focused on analytical procedures for confined aquifers that are bounded and nonleaky. Its purpose is to guide the calculation or estimation of transmissivity and storage coefficient from suitable field or test data. As a technical document, it helps users apply a recognized method when analyzing aquifer behavior, reducing variability in how results are interpreted. The practice is especially relevant when a consistent framework is needed for groundwater assessment and reporting.
Where is ASTM D5270/D5270M used?
This standard is commonly used in hydrogeology and groundwater testing work involving confined aquifers. It may be applied during aquifer tests, data analysis, and technical evaluations where transmissivity and storage characteristics must be determined for a bounded, nonleaky system. ASTM D5270/D5270M is also useful in consulting, environmental assessment, and water-resources projects where documented analytical procedures are needed to support defensible conclusions and project comparisons.
Why is ASTM D5270/D5270M important?
ASTM D5270/D5270M matters because it helps bring consistency to the analysis of aquifer test data. Using a recognized ASTM standard can support compliance efforts, improve confidence in technical findings, and reduce uncertainty in groundwater evaluations. For procurement, reporting, and quality control, it offers a common reference for how transmissivity and storage coefficient are determined. That can make results easier to review, compare, and apply in engineering or resource-management decisions.
