Erin A Stelzer
Erin received her Bachelor of Science degree in Microbiology from The Ohio State University. She started her career at the USGS in 2006 at the Ohio Water Science Center. Currently, Erin is working on a variety of molecular microbiological topics including: cyanobacterial toxin genes, taste and odor genes, enteric viruses, and eDNA.

Using host-associated genetic markers to investigate sources of fecal contamination in two Vermont streams Using host-associated genetic markers to investigate sources of fecal contamination in two Vermont streams
The use of host-associated Bacteroidales-based 16S ribosomal ribonucleic acid genetic markers was investigated as a tool for providing information to managers on sources of bacterial impairment in Vermont streams. The study was conducted during 2009 in two watersheds on the U.S. Environmental Protection Agency's 303(d) List of Impaired Waters, the Huntington and the Mettawee Rivers...

Quantifying viruses and bacteria in wastewater—Results, interpretation methods, and quality control Quantifying viruses and bacteria in wastewater—Results, interpretation methods, and quality control
Membrane bioreactors (MBR), used for wastewater treatment in Ohio and elsewhere in the United States, have pore sizes small enough to theoretically reduce concentrations of protozoa and bacteria, but not viruses. Sampling for viruses in wastewater is seldom done and not required. Instead, the bacterial indicators Escherichia coli (E. coli) and fecal coliforms are the required microbial...

Semi-quantitative evaluation of fecal contamination potential by human and ruminant sources using multiple lines of evidence Semi-quantitative evaluation of fecal contamination potential by human and ruminant sources using multiple lines of evidence
Protocols for microbial source tracking of fecal contamination generally are able to identify when a source of contamination is present, but thus far have been unable to evaluate what portion of fecal-indicator bacteria (FIB) came from various sources. A mathematical approach to estimate relative amounts of FIB, such as Escherichia coli, from various sources based on the concentration...

Results From a Microbial Source-Tracking Study at Villa Angela Beach, Cleveland, Ohio, 2007 Results From a Microbial Source-Tracking Study at Villa Angela Beach, Cleveland, Ohio, 2007
During the 2007 recreational season at Villa Angela Beach in Cleveland, Ohio, scientists with the U.S. Geological Survey (USGS) and the Northeast Ohio Regional Sewer District (NEORSD) found high Escherichia coli (E. coli) concentrations that were not easily explained by results obtained to date in ongoing investigations of recreational water quality at the beach. To help understand the...
