Course Reviews (4.6/5):

Overview: This course provides a practical review of key chemistry principles essential for understanding contaminant behavior in soil, air, and water. The course begins with a review of atomic structure and the environmental applications of the periodic chart. The course then progresses through topics such as chemical bonds, chemical reactions, inorganic chemistry, and organic chemistry. Environmental professionals working in water quality, stormwater management, contaminated site assessment, and remediation will benefit from attending.

This course is followed by the Principles of Contaminant Transport and Fate in Soil and Groundwater training, November 17 - 18, 2026, which is recommended for those working on contaminated soil and groundwater sites.

Course Topics:

Physical and Chemical Properties of Contaminants (S, Kd, Koc, Kow, Kh, Tb, Tm)

Environmental Applications of the Periodic Table

Oxidizers, Reducers, and Oxidation States

Mass-Based and Molar-Based Concentrations

Covalent versus Ionic Bonding

Empirical, Chemical, and Structural Formulas

Lewis Dot Notation

Predicting Molecular Geometry

Solubility Rules, Precipitation, and Sedimentation

Chemical Reactions, Kinetics, and Thermodynamics

Stoichiometry

Chemical Equilibrium and Limiting Reactants

Redox Potential and pH

Microbes and Terminal Electron Acceptors

Polyatomic Oxoanions (nitrate, phosphate, perchlorate, etc.)

Organic Molecules and IUPAC Nomenclature

Common Soil and Water Quality Monitoring Parameters

Predicting Contaminant Behavior

Intended Audience: Environmental professionals seeking an improved understanding of environmental chemistry. The course is especially helpful for those working with chemical data who have not had a chemistry refresher course in over ten years.

Education Level: Introductory/refresher to intermediate.

Course Materials: 2026 updated course proceedings (124 color pages - PDF).

Credit: 7.5 PDHs or 0.75 CEUs for completing 7.5 hours of instruction.

Registration: $395, $295 per person for small groups of 2 to 9 people, $250 per person when registering a large group of 10 or more on the same registration. Each registrant will receive their own link to join the training and may participate from any location with internet access. Register online or by calling us at (800) 385-0783.

Location: Your home or office - anywhere you can get comfortable and online.

About the Instructor: Erick McWayne has over thirty years of professional experience in environmental quality management and teaching related courses. As a consultant, he managed contaminated surface water, soil, and groundwater projects for the Department of Defense and other clients. He currently provides consulting support to environmental projects and teaches courses in contaminant chemistry, transport and fate, geochemistry, hydrogeology, and remediation with the University of California Davis and the National Environmental Management Academy (NEMA).
