ABSTRACT This guide covers what and how information should be recorded in the field when sampling a ground-water monitoring well. This guide is limited to written documentation of a ground-water sampling event. When sampling ground-water monitoring wells, it is very important to thoroughly document all field activities. It is important to record procedures used and measurements immediately after they have been accomplished and are fresh in the memory. The format of the documentation is discretionary, but should be consistent from well to well and in accordance with regulatory requirements. SIGNIFICANCE AND USE 4.1 When sampling groundwater monitoring wells, it is very important to thoroughly document all field activities. Sufficient field data should be retained to allow one to reconstruct the procedures and conditions that may have affected the integrity of a sample. The field data generated are vital to the interpretation of the chemical data obtained from laboratory analyses of samples. Field data and observations may also be useful to analytical laboratory personnel. 4.2 Due to the changing nature of regulations and other information, users are advised to thoroughly research requirements related to packaging and shipping prior to initiating a sampling event. Note 1: The sampling of an individual groundwater monitoring well should be repeated as closely as possible each time the monitoring well is sampled. This reduces the variability of the chemical parameters due to sampling variability which is the desired result. The intent is to detect the change in chemistry by repeating the sampling protocol at each individual well. This does not mean that all the wells are sampled the same way, nor does it prohibit changes in the sampling protocol, provided they are planned and documented. Note 2: The quality of the results produced by this standard is dependent on the competence of personnel performing it, and the suitability of the equipment and facilities used. Agencies that meet the criteria of Practice D3740 are generally considered capable of competent and objective testing/sampling/inspection/etc. Users of this standard are cautioned that compliance with Practice D3740 does not in itself assure reliable results. Reliable results depend on many factors; Practice D3740 provides a means of evaluating some of those factors. SCOPE 1.1 This guide covers what and how information should be recorded in the field when sampling a groundwater monitoring well. Following these recommendations will provide adequate documentation in most monitoring programs. In some situations, it may be necessary to record additional or different information, or both, to thoroughly document the sampling event. In other cases, it may not be necessary to record all of the information recommended in this guide. The level of documentation will be based on site-specific conditions and regulatory requirements. 1.2 This guide is limited to written documentation of a groundwater sampling event. Other methods of documentation (that is, electronic and audiovisual) can be used but are not addressed in this guide. The specific activities addressed in this guide include documentation of static water level measurement, monitoring well purging, monitoring well sampling, field measurements, groundwater sample preparation, and groundwater sample shipment. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 This guide offers an organized collection of information or a series of options and does not recommend a specific course of action. This document cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this guide may be appli...
Abstract
Overview
ASTM D6089-19(2023), titled Standard Guide for Documenting a Groundwater Sampling Event, is a comprehensive standard developed by ASTM International. The guide outlines essential recommendations for written field documentation during the sampling of groundwater monitoring wells. Thorough and consistent recordkeeping as described in this standard is critical to maintaining data integrity, supporting regulatory compliance, and ensuring reliable evaluation of groundwater quality.
This guide applies specifically to written documentation of field activities, procedures, and measurements performed during groundwater sampling. While electronic or audiovisual documentation is not addressed, written records remain the foundation for most regulatory and programmatic needs. The standard places emphasis on clear, immediate, and consistent reporting, accommodating site-specific and regulatory variations.
Key Topics
Essential Field Documentation
- General Site Details: Record facility and site name, well identification, weather conditions, sampling team members, and calibration details for instruments.
- Static Water Level Measurement: Document the depth to water from a designated reference point, measurement units, method and equipment used, and date and time.
- Well Purging Operations: Accurately record purging method, calculated purge volume, volume removed, pumping rate, equipment used, purging duration, water appearance before and after purging, and water management practices.
- Well Sampling Procedures: List types of analytes, order of sample collection, container details, collection equipment, sampling date and time, and any field observations or issues encountered.
- Field Measurements: Capture all field metrics, instrument calibration details, and timing of readings.
Chain of Custody and Sample Integrity
- Maintain robust chain of custody records for all samples, explicitly documenting every transfer and handling step.
- Label all samples with critical information such as identification number, collector’s name, date/time, site details, and applicable preservation methods.
Sample Preparation, Labeling, and Shipping
- Provide full details on sample preparation methods, chemical preservatives used, and storage/shipment conditions.
- Follow regulatory and shipping requirements to ensure sample integrity and transport safety.
- Attach analytical request forms, shipping documentation, and other supporting paperwork as mandated.
Consistency and Variability Management
- Repeat sampling protocols at individual monitoring wells as closely as possible for each event, reducing analytical variability.
- Document deviations from the sampling plan and note any changes in field conditions or procedures.
Applications
The ASTM D6089-19(2023) standard is utilized across multiple sectors engaged in groundwater monitoring and environmental site assessment, including:
- Environmental consulting firms documenting groundwater sampling events for regulatory compliance and data validation.
- Industrial and municipal site operators responsible for ongoing groundwater monitoring programs.
- Analytical laboratories using field records to interpret laboratory results and ensure validity.
- Government agencies overseeing site remediation, hazardous waste monitoring, and permitting processes.
By following this guide, organizations can:
- Enhance the reliability and reproducibility of groundwater quality data.
- Facilitate regulatory reporting and audits.
- Support robust data interpretation and defensibility in scientific and legal settings.
