Lab Schedule

Lab assignments are due at 23:59:59 on Sunday unless otherwise specified. The best place to keep track of due dates is Canvas. In general, the lab is highly flexible and it is up to you and your lab partner(s) to plan and making continual progress.

This schedule is subject to change as needed.

During the project lab, students will complete the water analyses listed here independently / in groups. Students must learn to use chemical instrumentation available in WCU's instrumentation facility and use it to accurately analyze their samples.

Analysis methods for 2024:

  1. ICP-MS (major cations and trace metals)

  2. Ion Chromatography (major anions)

  3. Alkalinity/ANC Titration

Other analyses are possible if your group is interested โ€“ just ask your instructor.

Students should analyze their sample with these methods and complete a charge balance and analysis of geochemical facies. You will very likely fail your first several tries at analyzing your samples โ€“ this is why so much time is devoted to the project! The goal is to turn in results that are both highly accurate and very precise at the end of the semester, and you should have enough data to strongly indicate high levels of precision and accuracy. Again, you likely will not meet this bar after your first try at analyzing your samples, so anticipate redoing it until you get it right!
