Drilling Fundamentals for Hydrogeologists and Engineers (short course #373)
Date: December 2, 2019
This one-day course is designed to acquaint — or reacquaint — you with:
- Various drilling methods
- Well design concepts
- Design calculations
- Troubleshooting techniques.
In addition to the nuts and bolts, health and safety considerations will be addressed, as well as building rapport with other groundwater professionals at the drill site and on the project.
PFAS in Groundwater Workshop: The Professional's Challenge (#139)
Date: December 5, 2019
Designed to be highly participative, this NGWA workshop will address and sharpen the thought processes of practitioners regarding how to apply scientific and legal considerations to sites contaminated with per- and polyfluoroalkyl substances (PFAS), a unique class of emerging contaminants widespread in groundwater and surface water, which, due to their toxicological characteristics, are increasingly the focus of environmental protection agencies worldwide.
PFAS include several thousand individual chemical compounds, each with at least one carbon-fluorine (C-F) bond and most of which are soluble in groundwater. The C-F bond is one of the strongest chemical bonds in nature. While useful in a wide variety of applications, the unique C-F chemistry of PFAS also creates significant challenges in water treatment and remediation. The fate, transport, and chemical transformations of most PFAS in the environment are still unknown and are areas of active scientific research.
Those who complete the workshop will receive the PFAS Site Assessment and Remediation Certificate.
Software Support for Decision Support Modeling: An Overview (short course #333)
Date: December 5, 2019
Discover how decision-making may be improved with the use of groundwater modeling value-added software in this one-day short course, which describes how model-partner software codes — particularly those that are available through the public domain PEST and PEST++ suites — can be of help.
This course provides a high-level description of how these codes work with models, and of the algorithms that they employ for model calibration, uncertainty analysis, sensitivity analysis, and management optimization. Examples of their deployment in real-world modeling contexts, and the impact that they can have on the decision-making process, are also presented.
Applications of Groundwater Geochemistry (short course #485)
Dates: December 5-6, 2019
Instructor: Bill Deutsch
This two-day course will provide you with the knowledge you need to evaluate contaminant migration and design remediation systems based upon the geochemical parameters of your site.
While a basic understanding of geochemical concepts is a good start, knowing how contaminants will behave in a variety of geochemical settings is vital in conducting site assessments or designing an effective remediation project.
Conditions resulting from groundwater and aquifer/soil interactions will be discussed and the effects of introducing a variety of contaminants will be examined. Case studies will be used to explain data collection requirements, laboratory analytical methods, and interpretation of data. Class exercises, including ones on characterization and aquifer remediation, will be used to reinforce concepts presented in the lectures.
GW/SW Interactions: Field/Mathematical Approaches to Evaluating GW Seepage/Attenuation (course #242)
Dates: December 5-6, 2019
Gain refined understanding of the processes used to evaluate groundwater/surface water interactions, an increasingly timely topic, during this two-day NGWA short course.
Groundwater and surface water are an interconnected water resource. In particular, groundwater and surface water interactions are complex, being controlled by numerous variables that may change spatially and temporally. As interest in groundwater and surface water interactions is increasing in response to limited water resources, sediment combination, and climate change, refined understanding of the processes at the groundwater/surface water interface is critical.
The objectives of this short course are to present scientific methods and regulatory conditions associated with the groundwater/surface water interface. This interface is dynamic in nature, reflecting both groundwater discharge and recharge conditions. Methods to measure and mathematically describe the conditions and processes at the interface will be presented.
The course will entail two days of study. The first day will present and implement field methods. The field work will apply piezometers, permeameters, and seepage meters to measure the flux in the groundwater/surface water interface. Other field methods will be discussed and implemented to characterize the water quality conditions at the interface.
Data from the first day will be utilized in the second day, which will focus on application of mathematical methods to quantitatively characterize the groundwater/surface water interface. The initial section of the session will include a description of commonly used analytical and numerical approaches to assess groundwater flux and hydraulic movement between surface water and groundwater. The second portion of the session will discuss methods to evaluate the attenuation capacity in the zone of surface water/groundwater interaction.
