ASTM D5787

ASTM D5787 is the ASTM standard for monitoring well protection at or near land surface, helping define how a wellhead or protective assembly should be managed where the well is exposed to surface conditions. It is relevant to preserving access, reducing damage, and supporting the long-term reliability of monitoring wells. For projects that depend on groundwater data, this standard provides a practical technical reference for consistent protection practices and better field management.

What is ASTM D5787?

ASTM D5787, titled Standard Practice for Monitoring Well Protection At or Near Land Surface, addresses the protection of monitoring wells in the area where they meet or extend above ground level. Its purpose is to support practices that help safeguard the well from physical damage, contamination pathways, and unintended interference. As an ASTM standard, it is generally used as a technical reference for planning, installing, or maintaining surface-level well protection in a consistent and defensible way.

Where is ASTM D5787 used?

This standard is commonly used in groundwater monitoring programs where wells must remain accessible and protected at the surface. It may apply to environmental site monitoring, remediation projects, and field locations where monitoring wells are installed near land surface and need ongoing protection from traffic, equipment, weather exposure, or tampering. ASTM D5787 is also useful during inspection and maintenance activities when wellhead protection practices need to be evaluated against a recognized ASTM reference.

Why is ASTM D5787 important?

ASTM D5787 helps organizations apply a consistent approach to protecting monitoring wells, which can support data integrity and reduce avoidable damage. In practice, this can matter for compliance, quality control, and procurement decisions when surface protection measures must be selected or reviewed. Using a recognized standard may also reduce risk by helping ensure the well remains usable, identifiable, and less vulnerable to disturbance over time. ASTM D5787 supports clearer expectations for field performance and maintenance.
