  2. Confirm your prediction by sampling and counting enterococci.
  3. Identify the factors that affect water quality at each site.

 

Think carefully about where sources of contamination might be coming from, the amount of impervious surface, and the size of the stream. When you make your prediction, check it in the applet below.
