About This Item
ASTM D7929 is the ASTM standard guide for selecting passive techniques for sampling groundwater monitoring wells. It helps users evaluate which passive sampling approach may be appropriate for a given monitoring objective, supporting more consistent field decisions and clearer method selection. By focusing on selection rather than a single device or procedure, the guide is useful for environmental professionals who need a practical reference when planning groundwater monitoring activities and aligning sampling choices with site conditions.
Purpose of ASTM D7929
The purpose of this guide is to provide a structured basis for choosing passive techniques for groundwater monitoring wells. ASTM D7929 is intended to help users compare passive sampling options in a way that is relevant to field application, monitoring goals, and well conditions. As a technical reference, it supports more informed selection of sampling methods and can reduce uncertainty when deciding how to collect groundwater samples in a monitoring program.
Common use cases of ASTM D7929
This standard is commonly used when planning groundwater monitoring at environmental sites where passive sampling techniques are being considered. It is relevant to consultants, site managers, and laboratory or field teams that need to decide whether a passive approach fits a monitoring well and the intended sampling objective. ASTM D7929 may also be used during method selection for routine monitoring, site investigations, and comparative evaluation of sampling approaches before field deployment.
Why ASTM D7929 matters
ASTM D7929 matters because sampling method selection can affect data consistency, comparability, and confidence in groundwater monitoring results. A clear guide helps reduce the risk of choosing a technique that does not match the well conditions or monitoring purpose. For procurement, project planning, and quality control, this standard provides a common technical reference that can support compliance-minded decisions and more defensible field practices.
