This study suggests that a more diverse bacterial community in beach sand and water may indicate a lower contamination site and better water quality. This study examined the sand and water bacteria of similar sites to compare recreational water quality, measured by the cultural fecal indicator bacteria (FIB). The study supported the growing body of evidence that community-based molecular tools can be used to identify the source and potential impact of fecal pollution in the environment. The researchers found that sand and water samples “hosted distinctly different overall bacterial communities.” Read more here: http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0090815
