PFAS in Groundwater Workshop: The Professional’s Challenge

PFAS in Groundwater Workshop: The Professional’s Challenge (#139)

Date: December 6

CEUs: 0.65


Overview

 

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.


This one-day workshop will include an opening presentation followed by three group work sessions and discussions, all designed to improve analytical and problem-solving skills.used analytical and numerical approaches to assess groundwater flux and attenuation in the hyporheic zone. These approaches will be presented relative to existing regulatory science.

 Member price:

  • On/before Nov 2 — $295
  • Starting Nov 3 — $395

Nonmember price:

  • On/before Nov 2 — $445

Groundwater/Surface Water Interactions

Groundwater/Surface Water Interactions: Field and Mathematical Approaches to Evaluating Groundwater

 

Date: December 6-7, 2018

Instructors:   


Course overview

 Learn about the tools and techniques used to characterize groundwater/surface water interactions, an increasingly timely topic as interest in this topic grows, during this two-day NGWA short course.


Groundwater and surface water are interconnected water resources. Their 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.


You will learn about the tools and techniques used to characterize these interactions to be able to evaluate the environmental risk they pose at contaminated waterways. You will also gain insight on the evolving regulatory perspectives relative to resource management, environmental investigations, and remedial actions.


Scientific methods, processes, and regulatory conditions associated with the groundwater/surface water interface — which is dynamic in nature, reflecting both groundwater discharge and recharge — will be presented. 

 Member price:

  • On/before Nov 2 — $925 
  • Starting Nov 3 — $1,025

Nonmember price:

  • On/before Nov 2 — $1,125 
  • Starting Nov 3 — $1,225

Introduction to Groundwater Geochemistry Reaction Modeling

Introduction to Groundwater Geochemistry Reaction Modeling (#292)

 

Date: December 6-7, 2018

Instructor: Bill Deutsch 

CEUs: 1.5


Course overview

This two-day short course will provide you an introduction to the important geochemical processes that affect groundwater composition and methods for developing reasonable conceptual models using site-specific data. Conceptual models will also be combined with an equilibrium modeling code to produce a geochemical model of a site.


The geochemical processes that affect rviewthe composition of natural groundwater and the movement of groundwater contaminants include a wide variety of solid phase/water and gas interactions in the subsurface. It is oftentimes impossible to predict the impact of these interactions on groundwater composition without a realistic conceptual geochemical model of the system and a means to calculate the interdependent chemical reactions.


This course will strengthen your understanding of the fate and transport of groundwater contaminants, and provide you with techniques and software for using site data to develop geochemical models for a given site. In addition to site understanding, geochemical models can be used in a predictive mode for evaluating natural attenuation of contaminants and designing in situ and ex situ remediation methods.


You will receive an introduction to groundwater geochemistry and chemical reaction modeling using PHREEQCI (free, widely used USGS code) for natural and contaminated systems. Emphasis will be placed on inorganic reaction modeling involving major ions and trace metals. Each session will include a discussion of an important geochemical process (such as mineral dissolution/precipitation, oxidation/reduction, or adsorption/desorption) and a demonstration of modeling the process with PHREEQCI. Practice sessions will integrate examples presented in lectures into realistic problems to provide valuable experience in modeling at specific sites.
