Water Testing and Data Analysis

Basically, the water testing teams job is to monitor the water quality of Rose Bay. The water quality of Rose Bay became a mess when they built the bridge at Rose Bay. The state of Florida is currently building a new bridge in hopes that it will fix the water quality of Rose Bay. The water testing team is documenting the water quality at Rose Bay before, during, and after the reconstruction of the bridge to see if the quality of the water improves due the new bridge.

A sample of the types of data being collected are displayed below. Three sites are used:

Randolyn Roberts, while in 10th grade, took water samples from the Rose Bay bridge. She went to the Halifax hospital and grew the samples on two petri dishes, Blood and Macconkey, by using the 1,000 loop for the growth number. She kept the plates in an incubator for 48 hours. Most of the bacteria that developed on the plates were e-coli and bacillus. She also began to take gram stains of some the growths (the most interesting ones). She came the conclusion that during the rainiest seasons there seemed to be more bacteria than there was during the dry seasons. A sample of her data is shown below.
