Special_Topics : RainFallpH (20 Variations) The rainfall in central Wisconsin has a pH of 4.8 (National Atmospheric Deposition Program). Take a look at the EPA webpage Effects of Acid Rain: Lakes & Streams. This site has a chart of the pH at which several aquatic species begin to suffer. Determine which of the following species will be most affected by rainfall of this acidity if the lakes and streams in central Wisconsin aren't buffered enough to neutralize some of the acid. (There may be more than one correct answer.)
Geographical Information Systems (GIS) Mapping of Environmental Samples across College CampusesKathleen L. Purvis-Roberts, Harriet P. Moeur, and Andrew Zanella In this laboratory experiment, students take environmental samples (concentrations of nitrogen dioxide) and geospatial coordinates with a global position systems unit at various locations around campus, map their data on a geo-referenced map with geographical information systems software, and compare their results to those observed by governmental agencies.
