Topics Include:
Borehole Geophysics – Hager-Richter Geoscience
The methods to be presented are non-invasive borehole geophysical methods that provide in-situ subsurface conditions for (1) environmental investigations to characterize overburden, bedrock, and groundwater flow; (2) geotechnical investigations to characterize subsurface geology and man-made structures; (3) investigation for water resources; and (4) exploration investigations for minerals, oil, and gas.
Borehole geophysical logging methods can be used as part of a subsurface investigation program to supplement other methods (drilling, sampling/lab testing, surface geophysics) and provide high resolution in-situ results to characterize geologic/hydrogeologic conditions and conditions of man-made structures throughout many stages of a project lifecycle. This presentation will include information on how borehole geophysical logging results can be used as part of geologic/hydrogeologic and geo-engineering investigations, specific logging methods will be discussed along with limitations of the methods, logging deliverables will be presented, and a demonstration will be provided giving those attending the opportunity to see borehole geophysical logging equipment including the logging winch, control unit, and a multitude of individual logging probes.
Slug Testing – Gould Groundwater Geosciences and Ramboll
The method to be presented involves the displacement of a quantity of water in a well and measurement of the time it takes for the water level to return to static conditions. The relationship of displacement and recovery time is used to calculate hydraulic conductivity. Slug tests typically occur in pairs often referred to as falling head (slug) and rising head (bail) tests. The method or device used to displace water must be matched to the well specifications, aquifer conditions and concerns about groundwater contamination.
Well Design – Guy Swenson
Well design is critical for groundwater extraction wells and the principles of well design can be important for monitoring wells. Well design involves selecting appropriate well components to efficiently and cost effectively achieve the project objectives. The use of well design principles will provide an efficient production well for a public water supply or for remedial groundwater extraction. Often well design for monitoring wells is limited, which can compromise the ability to effectively monitor and test the aquifer.
This presentation provides an overview of the components and principles of well design and why well design is important for both extraction and monitoring wells. The issues to consider in order to design a well that meets project objective in a cost-effective manner are discussed. A better understanding of the value of well design will improve one’s ability to design and install more effective monitoring and extraction wells for groundwater supply and environmental monitoring and remediation programs.
UAS Site Reconnaissance – Ramboll
Since 2017, UAS or Unmanned Aerial Systems, aka drones, have been rapidly expanding in their use in multiple fields and applications. Drones provide us a with a safe and efficient platform to collect data from imagery to physical samples. Previously, this type of data was expensive and potentially risky to collect. Today, with relatively little training, almost anyone can obtain inexpensive drones and be able accomplish numerous tasks that may have been previously out of reach.
This presentation will focus on their use in geologic environmental remediation. We will discuss; what a UAS/UAV/Drone is and how it works, FAA PART 107 regulations regarding their use, a few best practices and methods, and finally we’ll discuss a few case studies using UAS.
Soil Logging and Classification – Ramboll
Consistent and clear soil logging methods are essential to the classification of unconsolidated materials during the course of environmental, geotechnical, and groundwater supply investigations. The logging of physical characteristics of soils and other unconsolidated materials is a fundamental component of well design, evaluation of transport mechanisms, hydrogeologic modelling, conceptual site model development, evaluation of remedial alternative feasibility, engineering design, and much more.
This presentation provides an overview of soil logging components and introduces how they are used within the Unified Soil Classification System (USCS). The presentation will include a soil logging demonstration of a split-spoon sample supported by an overview of selected tools and testing methods commonly used in a field setting.
Introduction to Geotechnical & Environmental Drilling – William Hackett & William Kappel
This presentation provides an overview of drill rig components and the purpose of geotechnical and environmental drilling. The demonstration will provide a real-world visualization of the topics discussed.
Air Monitoring – PID Basics – Ramboll
This presentation includes a review of basic PID characteristics and functionality.
MiHPT Direct Imaging – Parratt-Wolff and S2C2
This presentation will introduce the components and application of membrane interface and hydraulic profiling tooling (MiHPT). Participants will walk away with a basic understanding of tooling utilized for direct imaging for environmental investigations. A brief demonstration will provide a real-world visualization of the topics discussed.
Low Stress (Low Flow) Purging and Sampling Procedure for the Collection of Groundwater Samples (USEPA 2010) with Regards to PFAS – ERM
This presentation will focus on the low flow purging and sampling procedure, which includes recommended groundwater sampling equipment, stabilization criteria required to collect a groundwater sample, step-by-step instructions on when and how to collect a groundwater sample, how to handle samples after collection, chains of custody, and project analytical goals. Passive Diffusion Bag (PDB) sampling theory and procedures will also be discussed. PFAS considerations will also be reviewed regarding what not to use when collecting PFAS groundwater samples (equipment, supplies, etc.), the sample order for PFAS, and how to sample for PFAS.
