Environmental Soil Chemistry. 2nd Ed. Academic Press Stumm, W. and J.J. Morgan. 1996. 3rd ed. Aquatic Chemistry. Wiley</p><p>Course Objectives: </p><p>1. Develop an understanding of the fundamental chemical processes that control material cycles within and among the atmosphere, hydrosphere, and geosphere. </p><p>2. Build a foundation of chemical principles for understanding the behavior of chemical constituents in soil and water systems.</p><p>3. Gain experience in applying these principles to biogeochemical cycling, environmental problems, and land management issues. </p><p>Recitation Objectives:</p><p>1. Gain an appreciation for routine and advanced quantitative analysis of soils, geomaterials and natural waters. </p><p>2. Develop experience in chemical equilibria to understand problems in bioremediation ience in geochemical processes such as solubility, speciation, and fate and transport. </p><p>3. Utilize case study assignments to understand chemical principles and processes important in current global, national and or regional issues. </p><p>Grading:</p><p>Quizzes-Mix 100 pts. Final Exam 100 pts. Problem Sets 100 pts. Recitation Assignments 200 pts. Group Project/Abstracts 50 pts.</p><p>TOTAL 550 pts</p><p>Notes: No make-ups on exams, unless there is an emergency.
