Chemical reactions in the atmosphere, the land surface and in the groundwater determine the distribution of both beneficial and toxic materials on earth that may affect resource distribution and human health. Chemistry of Natural Waters examines the elements and reactions that govern the mobility, stability and distribution of nutrients, salts and toxins in freshwater, marine, atmospheric and groundwater systems. Chemical analysis techniques, field methods, computer applications and problem solving are important components of the course. Prerequisites: General Chemistry I (CHEM-101, -103, or -111) or General Chemistry II (CHEM-102, -104 or -112). 4 SH. 3 lecture hours, 3 laboratory/field hours. CC: Oral Intensive.
