ASTM D8571

ASTM D8571 is the standard practice for detecting hydrocarbon liquids in soils by fluorescence with an optical imaging profiler using direct push methods. It provides a technical approach for identifying potential hydrocarbon impacts in subsurface soil by measuring fluorescence response in situ or during direct push investigation work. This matters because it supports more consistent field screening, helps target follow-up sampling, and can improve decision-making when evaluating suspected contamination sites.

ASTM D8571 standard overview

ASTM D8571 addresses a practical field method that combines fluorescence detection, optical imaging, and direct push tools to locate hydrocarbon liquids in soil. As a standard practice, it is best understood as a procedure for investigation and screening rather than a prescriptive treatment or remediation document. The title indicates a focus on soils, hydrocarbon liquids, and profiler-based imaging, which suggests use in site characterization workflows where rapid subsurface assessment is needed. ASTM D8571 helps define a repeatable framework for those measurements.

Where is ASTM D8571 used?

This standard is commonly used in subsurface investigation programs where hydrocarbon liquids may be present in soil and direct push methods are appropriate. It is relevant to field teams using optical imaging profilers and related direct push equipment to gather screening data during site assessment, environmental investigation, or verification work. ASTM D8571 is especially useful when practitioners need a faster way to identify likely zones of impact before deciding on confirmatory sampling or additional analysis.

Practical importance of ASTM D8571

ASTM D8571 matters because it can improve consistency in how hydrocarbon-related soil conditions are detected and documented. By providing a recognized practice, it supports quality control, procurement decisions, and compliance-oriented workflows where a common technical basis is important. It may also help reduce uncertainty during field screening by making the use of fluorescence and optical imaging more repeatable across projects. For teams evaluating potential contamination, that consistency can support better risk management and more efficient follow-up actions.
