Topic: Sampling Event Documentation
Document… document… document! Paperwork is the part of a sampling event that sampling teams hate the most! This module explains in detail the various mechanisms available for documenting field activities, taken from the approach of ensuring that mechanisms are in place to make certain that your field documentation is both traceable and defensible. The three key options for field recordkeeping - written records, electronic records and audio-visual records - are discussed in detail in this module. This module is appropriate not only for sampling team members but also for regulatory personnel who may be involved in enforcement cases that require the collection of evidence for court cases.

Topic: Planning and Executing a Successful Ground-Water Sampling Event
The ground-water monitoring wells are installed and developed and you are finally ready to sample! Or are you? This module discusses in great detail all of the issues that need to be considered and documents that need to be in place prior to setting out to collect ground-water samples. Learn why it is critical to prepare and follow a written, site-specific Sampling and Analysis Plan. If you are an emergency response team member or regulatory enforcement staff, learn what alternative approach you would need to take to conduct a sampling event. Learn why you need to understand the terms accuracy, precision, bias and defensibility. Field videos are included within this module to explain well inspection and good housekeeping practices that should be employed during a ground-water sampling event.

Topic: Field Equipment Decontamination Procedures
It is a common practice to use a variety of field equipment that travels from well to well during a ground-water sampling event. Portable equipment such as water-level gauges, flow cells, analytical instruments and multi-parameter sondes are examples of some equipment that is used in each monitoring well, even in situations where dedicated pumps are used. And, of course, where portable pumps are used, the pump (and, in many cases, the discharge tubing) will also travel from well to well. To avoid the potentially very serious and costly problem of monitoring well cross-contamination, it is critical to implement thorough and effective field equipment cleaning protocols. This module discusses in detail field equipment cleaning protocols that apply to drilling, soil sampling and ground-water sampling field equipment. Learn why a few of the “detergents” commonly used for field equipment cleaning should be avoided for some field applications because they may contain phosphates, and why others may introduce trace amounts of semi-volatile compounds if not diluted sufficiently. Field videos are included within this module to explain the practices and procedures used in decontamination of field equipment used in ground-water sampling events.

Topic: Field Quality Assurance/Quality Control Practices
You think your sampling team does a good job in the field, but how can you be sure, and have the confidence that the results they produce are valid and defensible? Learn how to ensure that your sampling practices are technically and legally defensible and how to prove to outside groups and auditors that the data being generated during a sampling event can be validated. In the real world, a lot of attention is placed on ensuring that laboratory data are defensible and can be validated, but the same is not always true for field work. The only way to have confidence in your ability to validate results of a sampling event is to have a strong field Quality Assurance/Quality Control program in place. This module explains in detail how to implement an effective field QA/QC program, exactly what elements should be included in field QA/QC programs, and the importance of collecting a variety of field QC samples. Field videos are included within this module to explain how to properly collect field QC samples during a ground-water sampling event.

Topic: The Science Behind Ground-Water Sampling
Have you ever wondered if there is a better method than you are currently using for collecting more representative water-level data and ground-water samples from your wells? Ever thought about all of the various sources of bias and error in water-level measurement and sample collection procedures and wondered how each could affect the data in your sampling program? This series of 2 modules provides an in-depth discussion of how water-level measurement and ground-water sampling protocols have evolved over the years and how, through decades of research, modern sampling methods (when implemented properly) can yield vastly improved field data and more representative ground-water samples. Learn how to anticipate and avoid the many potential sources of bias and error that may occur in water-level measurement and ground-water sampling programs, and what factors can affect the representative nature of the samples you collect. Field videos are included within the first module to explain how to collect ground-water level measurements using several different methods. While you may opt to take just one of these modules, it is strongly recommended that you take both modules in the prescribed order if you want comprehensive coverage of the subject.

Topic: Selection and Operation of Ground-Water Purging & Sampling Devices
There are a lot more useful and appropriate purging and sampling device options available than the bailer! Learn what types of sampling devices are appropriate for a variety of analytical parameters, and which devices should never be used for some parameters. This series of 2 modules provides a detailed discussion of a wide range of devices available for purging and sampling ground-water monitoring wells, including their principles of operation, operational characteristics, materials of construction, and limitations. The discussion will provide a framework for evaluating any device to determine its suitability and appropriateness for site-specific and individual well-specific applications. Field videos are included within each module to explain the operation and use of a variety of sampling devices. While you may opt to take just one of these modules, it is strongly recommended that you take both modules in the prescribed order if you want comprehensive coverage of the subject.

Topic: Conventional Purging and Sampling Practices
Since regulatory programs mandating ground-water monitoring and sampling at a variety of sites first started in the 1970s, a number of different approaches for collecting ground-water samples from monitoring wells have been implemented. Some of the “conventional” purging and sampling practices first used in the 1970s (like well-volume purging and sampling and purging a well to dryness) continue to be implemented today, even though it has been repeatedly demonstrated through decades of research that these methods are rarely, if ever, capable of producing representative samples. This module discusses how these practices are implemented, and how these and other practices are applied to both high-yield wells and low-yield wells that tend to go dry during purging. Discussions are provided to document the limitations that research has found with these purging and sampling practices. If you are still purging 3 to 5 well volumes as a purging strategy or if you are still purging wells to dryness then returning in 24 hours to sample (or if you are overseeing projects where these techniques are being used), then this is a module you should not miss! Field videos are included within this module to explain the practices and procedures used in conventional purging and sampling.

Conventional Purging and Sampling Practices for High-Yield and Low-Yield Wells
Total CEUs for Module GWM-22: 1.0 CEU
Topic: Low-Flow Purging and Sampling and No-Purge Sampling
Traditional ground-water sample collection methods, including well-volume purging and sampling and purging a well to dryness, are subject to significant sources of bias and error that commonly result in either over- or under-estimation of actual sample concentrations and poor precision and accuracy. It is thus exceedingly important to use more up-to-date methods, like low-flow purging and sampling and no-purge sampling, that have been demonstrated by many field research studies to produce higher quality samples so all stakeholders can have much higher confidence in sample analytical results. This series of two modules comprehensively covers the topics of low-flow purging and sampling and the newer methodology referred to as no-purge sampling, and explains why and how low-flow purging and sampling and no-purge sampling always produce dramatically improved and more consistent sampling results and significant cost savings. Field videos are included within these modules to help explain the practices and procedures required to implement low-flow purging and sampling and no-purge sampling. While you may opt to take just one of these modules, it is strongly recommended that you take both modules in the prescribed order if you want comprehensive coverage of the subject.

Topic: Field Parameter Measurement During Well Purging
Measurement of field water-quality indicator parameters is a fundamental component of most conventional purging and all low-flow purging and sampling approaches to collecting ground-water samples from monitoring wells. This module explains how to correctly measure the most common water-quality indicator parameters (including pH, specific conductance, dissolved oxygen and redox potential) and physical parameters (temperature and turbidity) used in conjunction with purging wells to ensure the collection of accurate data. You will learn which parameters to measure to achieve sampling program objectives and how to identify when field data do not make sense, and what the cause(s) may be. Field videos are included in this module to explain the practices and procedures used for field parameter measurement.

Topic: Ground-Water Sample Pretreatment – Filtration and Preservation
Ground-water sample chemistry, by nature, will change within seconds as samples are brought from in-situ conditions (within the ground-water system, where it is at higher pressure and stable pH and temperature relative to atmospheric conditions) to the surface. When these changes occur, the representative nature of the sample is compromised. This series of 2 modules discusses in detail the sample pretreatment methods, including sample filtration and preservation, that must be implemented in the field at the time of sample collection (not later, in the laboratory) to protect the physical and chemical integrity of the samples from the time the sample container is filled to the time it is extracted or analyzed in the laboratory. Upon completing these modules, you will know how to recognize and avoid several significant but common sources of error associated with field filtration and preservation of ground-water samples. Field videos are included within each module to explain the practices and procedures used in filtration and preservation of ground-water samples. While you may opt to take just one of these modules, it is strongly recommended that you take both modules in the prescribed order if you want comprehensive coverage of the subject.

Topic: Ground-Water Sample Handling and Shipment
Samples are collected and now you are ready to get them to the laboratory so they can be analyzed. You have a vested interest in ensuring that the samples arrive at the laboratory on-time and in one piece. As a sampling team member, if you are the one presenting the samples to an outside group for delivery to the lab, you are referred to as the sample “shipper” and, as such, you are taking on the responsibility of ensuring that samples are delivered in compliance with applicable shipping laws. That is a critical fact that many samplers are unaware of. This module discusses issues associated with delivery and shipment of both uncontaminated and hazardous samples from the field to the laboratory. While this module will not certify you to ship hazardous substances, it will give you an awareness of regulatory requirements, which include training. Field videos are included within this module to explain proper practices and procedures for ground-water sample handling and shipment.
