Illinois State Water Survey: Day 2
Water Chemistry
Champaign, IL
UMS WaterWorks students visited the Illinois State Water Survey in a multi day field in September 2005. In day 2 of the two day trip, students learned about water chemistry from a number of ISWS chemists and employees including Mary LaFaivre, Mark Brooks, Mike Machesky, RuthAnn Nichols, Lauren Sievers, Kaye Surratt, Dan Webb, Jennifer Tester, Kathy Konan, and Brian Kaiser. Students learned about water quality testing the in the Public Service Laboratory and they learned about measuring the chemistry of precipitation in the labs of the National Atmospheric Deposition Program. In addition, students received individual instruction in completing labs focused on testing of the chemistry of tap water, surface tension, filtration, acid rain, pH indicators, and dissolving of solutes.
