ASTM D5092/D5092M–16R24 Standard Practice for Design and Installation of Groundwater Monitoring Wells

The ASTM D5092/D5092M-16R24 Standard Practice for Design and Installation of Groundwater Monitoring Wells provides detailed guidance on the technical and procedural aspects of constructing groundwater monitoring wells that yield reliable, representative data. This standard covers the entire process, starting with site selection and well design tailored to specific hydrogeologic conditions and monitoring objectives. It specifies suitable materials for well casing, screens, and seals to prevent contamination and ensure structural integrity. The practice addresses drilling techniques and installation methods that minimize disturbance to the aquifer and surrounding formations. It also includes recommendations for well development to remove drilling fluids and fine particles, promoting accurate groundwater sampling and measurement. Emphasis is placed on preventing cross-contamination between aquifers and ensuring long-term well performance. The standard is intended for use by environmental professionals, engineers, and contractors involved in groundwater monitoring for regulatory compliance, site characterization, and remediation. By following ASTM D5092/D5092M-16R24, practitioners can establish monitoring wells that provide consistent, defensible groundwater data over the life of a project.

Key aspects:

Well Design

• Guidance on selecting well type, screen length, slot size, casing materials, and sealing to suit site-specific hydrogeologic conditions.

Site Selection

• Criteria for locating wells to effectively monitor groundwater flow, quality, and contamination plumes.

Drilling and Installation Techniques

• Recommended methods to minimize formation disturbance and prevent contamination during drilling and well construction.

Well Materials

• Specifications for durable, inert materials (e.g., PVC, stainless steel) to avoid chemical interactions with groundwater.

Well Development

• Procedures for removing drilling fluids and fine particles to improve water flow and sample representativeness.

Prevention of Cross-Contamination

• Techniques for sealing annular space to isolate aquifers and prevent vertical contaminant migration.

Documentation and Quality Assurance

• Importance of detailed records for well construction, materials used, and installation conditions for future reference and regulatory compliance.

Highlights:

• Provides a comprehensive framework for constructing reliable, long-lasting groundwater monitoring wells.
• Emphasizes minimizing aquifer disturbance and maintaining sample integrity.
• Supports regulatory compliance with environmental laws and guidance (e.g., EPA).
• Serves as a critical reference for environmental consultants, engineers, and contractors.
• Helps ensure monitoring wells deliver consistent, representative groundwater data essential for site characterization and remediation efforts.
