Source Molecular Corporation shared insights on measuring effectiveness of best management practices (BMPs) and discussed how the Host Fecal Source works at the Great Lakes Beach & Water Safety Conference held at the Doubletree By Hilton in Cleveland, Ohio, from October 23 to 25, 2018.
Source Molecular’s Chief Executive Officer Mauricio Larenas was one of the speakers of the conference session titled, Molecular Methods for Water Quality Testing, chaired by Dr. Orin Shanks, a geneticist at the U.S. Environmental Protection Agency (EPA) in the Office of Research and Development. Mr. Larenas’ presentation was about “Demonstrating BMP Effectiveness with Microbial Source Tracking & Host Fecal Score.”
Mr. Larenas pointed out that MST markers, being specific to their targeted fecal sources, can specifically demonstrate if a particular source (e.g. human fecal source or cow fecal source) has been mitigated by best management practice (BMP) even if FIB levels show little change. He also elaborated about the human fecal score (HFS), which was developed by a team of researchers, from the U.S. Environmental Protection Agency, Southern California Coastal Water Research Project (SCCWRP), and Stanford University. The HFS objectively assesses the extent of human fecal contamination at a site using a standardized mathematically defined approach and can be applied to other hosts as well.

Other presentations in the same session were “Fecal Non-Point Pollution Source Characterization at Chicago-Area Lake Michigan Recreational Beaches,” by Abhilasha Shrestha of University of Illinois at Chicago; “Evaluation of USEPA qPCR Methods for Beach Monitoring in Michigan,” by Rich Haugland of U.S. EPA and Shannon Briggs of the Michigan Department of Environmental Quality (DEQ); and “Improvements in Mitigating Interference in qPCR for Microbial Water Quality Monitoring,” by Kaedra Jones of ICF International.
The conference was hosted by the Great Lakes Beach Association (GLBA) and the Great Lakes Water Safety Consortium (GLWSC).
