Description:

This hybrid course includes an overview/refresher of key chemistry concepts associated with environmental contamination, provides a foundation for understanding contaminant transport, fate and remediation, and delivers an overview of key concepts essential for understanding soil & groundwater contamination and the selection of appropriate remediation approaches.

The fundamental environmental chemistry overview/refresher takes place on the first day of the course, and is followed by a review of chemical naming rules (e.g., understanding what 1,1,1-TCA is, etc.) and how to use chemical structure to predict molecular geometry and environmental behavior.

On the second day, the material covered expands into the overview of key concepts essential for understanding soil and groundwater contamination and the selection of appropriate remediation approaches. In the second half of Day 2, participants will use spreadsheet models to predict behavior of chemical using simplified examples. Major uncertainties and limitations of modeling approaches will also be discussed. This subject matter is useful for non-modelers who would like to better understand modeling results and the uncertainties associated with them, as well as for individuals who are well versed in modeling but could use a further background in chemistry to improve their skills in interpreting modeling results.

The course material will greatly enhance on-the-job training and is also recommended for project managers seeking a more thorough understanding of contaminant behavior.

"I liked that the course started out with a basic overview of Chem, then built on more complex concepts.  The course had very good, general information about contamination and was very useful." H. Zrucky, April 2013

"Good progression from chemistry overview into the various environmental chemistry concepts.  Instructor was knowledgeable and enthusiastic." P. Sartz, April 2013

"The way we were "eased" back into the organic chemistry was very helpful.  I had some pre-course anxiety about that." R. Duncan, April 2013

"[Pam Schultz is an] Excellent speaker, very intense knowledge and a passion for the subject material. Great job!" J. Collins April 2013

Course Topics

Day I: The goal for the first day of the course is to provide a refresher of chemistry concepts that are needed to assess contaminant fate and transport. Participants will understand the structure of major contaminants and an gain an understanding of the chemical properties that can be used to predict chemical behavior. The course will also cover sources of chemical property data and approaches to assessing data quality.

Specific topics covered:
• Elements, Compounds and Chemical Mixtures
• Isotopes, Ions, and Chemical Bonds
• Predicting Molecular Geometry and Behavior
• Empirical, Chemical, and Structural Formulas
• Organic Molecules and IUPAC Nomenclature
• Overview of Physical and Chemical Properties: Molecular Weight, Melting point, Boiling point, Solubility, Vapor pressure
• Mass-Based and Molar-Based Concentrations
• Chemical reactions: precipitation, oxidation-reduction , acid-base
• Stoichiometry (balancing reactions)
• Chemical Equilibrium and Limiting Reactants
• Major contaminant groups (e.g., BTEX, PAHs, PCBs, dioxins, halogenated compounds, pesticides)
• Contaminant partitioning and mass transfer
• Non-aqueous phase liquids (NAPLs)
• Contaminant mixtures (e.g., gasoline, coal tars)
• Properties of fluids: Density, Viscosity, and Interfacial tension

Day 2: The goal of the second day is to build upon the material from Day 1 to be able to understand the movement of contaminants in environmental systems. A key goal of Day 2 is to give participants more familiarity with modeling concepts and to be able to use simple models to make predictions of contaminant behavior.
• Hydrogeology Review
• Groundwater Transport
• Retardation and Solute Velocity Calculations
• Contaminant Transport

  • Advection, Mechanical Dispersion, Diffusion (Chemical Dispersion)
  • Adsorption and Absorption (Kd, Koc, foc)
  • Advection-Dispersion-Reaction Equations
  • Impact of heterogeneity

• NAPLs - Residual Saturation Calculation
• Vapor Transport
• Overview of Natural Attenuation Processes
• Biodegradation Pathways for Common Contaminants
• Case studies of contamination (e.g., gasoline, manufactured gas plants, dry cleaning solvents, metals)
• Overview of risk-based screening levels

 



 

About the Instructor

Pamela Schultz, PhD

Pamela Schultz, PhD

Dr. Pamela Schultz is an environmental chemist and engineer with over 20 years of experience working in government, industry, and consulting.  She obtained her undergraduate degree in chemistry from Providence College in 1992 and her master’s degree in Environmental Systems Engineering from Clemson University in 1996.  She worked as a senior environmental engineer at Merck & Co., Inc., conducting contaminant fate and transport modeling and human health risk assessments for air permitting and remediation projects. She later joined RTI International as a research environmental engineer, conducting multimedia fate and transport modeling to support U.S. EPA decision-making. In 2011, she received her PhD in Environmental Sciences and Engineering at the University of North Carolina, studying the behavior of dense non-aqueous liquids in soil and groundwater.
