Textbook: Contaminant Hydrogeology, 2nd Edition, C. W. Fetter. Prentice Hall. We will also be using part of the "on-line" Chapter 23 of Fundamentals of Ground Water, Schwartz and Zhang, Wiley, 2003. This is listed as S&Z 23 in the syllabus below. Additional readings (some of which are listed in the syllabus below) and class notes will be posted on the Learn@UW site for the class. You must be registered for the class to access the Learn@UW site.

5/10 T Take home final due at 5 PM  

Grading and course policies: Grades will be based on two in-class midterms (15 % each), a take-home final (20%), problem sets and site characterization project (40%), and two writing assignments (5 % each). The two writing assignments will be related to material covered on the two in-class midterms. The in-class midterms will be open book exams. The writing assignments and the take-home final are to be completed independently, without consultation or editing assistance from other students. Students will work in pairs or small groups on the site characterization project. A penalty will be applied to late assignments that are not excused due to illness or other approved circumstance.
