This simulation has been taught for many years in this course by Professor Bower using paper, note cards, and a simple data storage program. This digital version of simulation was developed using Macromedia Director with data created by the mapping program Surfer. Data can be collected at ten foot intervals anywhere on the site map. Data is collected from one or more of 39 data maps, which are color-coded to correspond to values for each data type. For example, one layer contains all the information about the depth to the bedrock under the surface. Other layers contain information about certain types of contamination at various depths.
