Question 12 (Essay Worth 5 points)
Sandy completed pH and fecal coliform tests on water samples from the pond in her backyard. She reported the results in the following charts. Two graphs showing water-quality indicators for Sandy's pond over one year. The graph labeled 'pH' shows that the pond's pH fluctuated between approximately 6.5 and 7.5. The graph labeled 'Fecal Coliform' shows that for most of the year there were approximately 10 colonies per liter of water in the pond. The exception was June, in which there were more than 100 colonies per liter of pond water. © 2010 FLVS What can you conclude about the water quality of Sandy's pond over the past year? Explain.
