Advanced undergraduate/graduate course that explores the chemical transformations of elements of the periodic table. Thermodynamic, kinetic, and mechanistic tools needed to address the multiple chemical species and interfaces that are present in natural waters and water-based technological processes are emphasized. Ligand exchange, metal ion exchange, adsorption/desorption, precipitation/dissolution, electron and group transfer reactions, and other concepts from coordination chemistry will be covered. Applications include elemental sources and sinks in ocean waters, reactive transport in porous media, weathering and soil genesis, nutrient and toxic element uptake by organisms, water treatment chemistry, and rational design of synthetic chemicals. Co-listed with EN.570.641

The best aspect of this course was the problems that were broken down into understandable segments for the benefit of the students. The course covered basic processes regarding wastewater treatment and gave students a comprehensive understanding of the operation procedure in a wastewater treatment plant. Some students felt the assignments were purposeful y excessive and too difficult to complete. One suggestion included shortening the study guides. Another suggestion was not making the final exam 135 cumulative. Prospective students should know that background knowledge in physiochemical treatment methods is beneficial.

The best aspects of this course were the well organized and interesting lectures, the knowledgeable and enthusiastic instructor, and the emphasis on homework. Many students thought the material itself was interesting and intellectually rewarding. The worst aspects of the course included the lack of feedback on homework leaving many students to wonder how they were doing in the course and the difficulty of the course for those without a strong chemistry background. Suggested improvements to the course include giving a brief review at the start of the semester and providing feedback on the work. Prospective students should have a fairly strong background in chemistry, and be prepared to learn a few computer programs independently.

Students enjoyed the interesting readings and intimate class size which facilitated relevant group discussion. Students appreciated gaining perspective from other students from diverse majors. Students felt that the readings were difficult and time consuming. Suggestions for improvement included having shorter class periods, assigned readings with a clearer perspective, and writing assignments due the day before so students are able to read classmates’ perspectives. Prospective students are encouraged to prepare for class discussion by thoroughly reading the assigned articles and taking notes on questions and ideas surrounding course topics.
