The main goal of this multi-part field and lab exercise is to introduce students to practical aspects of soil and water geochemistry. Some of the analyses for this lab are conducted in the field using field analytical instruments and rest of the analyses is conducted in a wet chemistry/geochemistry lab. There are several objectives: 1. Learn how to sample water and soil samples in a safe and effective manner 2. Collect basic aqueous chemical parameters in the field 3. Compare field collected data with that obtained using advanced instruments in the laboratory 4. Determine bulk physical and chemical properties of the soils in the lab 5. Determine trace and major element concentrations of the soils in the laboratory At the end of this exercise students will gain a better appreciation for how soil and water quality is assessed in multiple ways. They are also introduced to basic "tools-of-the-trade" in the environmental geochemistry and also using Excel to make simple and advanced calculations as well as for plotting data. During preparation of lab reports, they are introduced to basic elements of an effective data-based technical paper. Key words: urban watershed, soil chemistry, water chemistry, aqueous geochemistry, field analysis, analytical chemistry
