First Paragraph

The purpose of this activity is for students to investigate water quality, and the factors that affect it, at a local beach. This is accomplished by (1) measuring concentrations of Escherichia coli and Enterococcus, two types of bacteria commonly used as fecal indicators, in water and sand samples from a local beach; (2) interpreting the collected data with graphs, tables, and statistical tests; and (3) investigating the relationship between concentrations of fecal indicator bacteria (FIB) and other factors such as sampling location, distance from the shoreline, and grain size of sand.
