The microbiology program in the Ohio District has been steadily growing over the past ten years. Projects have evolved from monitoring of fecal-indicator bacteria in surface waters to studies that investigate the processes and factors that affect bacteria, viral, and protozoan pathogens and indicators in the environment.
Analyses for fecal-indicator bacteria are done by field personnel and guidance on
these methods can be provided by the Ohio District. In addition, the Ohio
District Microbiology Laboratory has the capability of analyzing samples for
coliphage, enteric viruses, Clostridium perfringens,
Cryptosporidium and Giardia. Escherichia Coli in the Swash Zone at Four Ohio Bathing Beaches,
