Source Molecular Attends Colorado Stormwater Council Meeting

Source Molecular Corporation gave a presentation on microbial source tracking (MST) at the general membership meeting of the Colorado Stormwater Council in January 2018.

Source Molecular’s CEO Mauricio Larenas attended the meeting along with local governments in Colorado who hold permits under the National Pollutant Discharge Elimination System (NPDES).  With the municipalities’ storm drainage systems discharging to state waters, the Council expressed an interest in learning more about the technology that will allow them to identify bacteria sources.

Colorado has its share of problems when it comes to water quality. The Council acts as a forum for municipalities and municipal permit holders. They regularly hold meetings wherein they welcome educational presentations.

Mr. Larenas explained to the council members Source Molecular’s laboratory capabilities. He noted that Source Molecular is the world’s only ISO 17025-accredited MST laboratory. It can perform Digital PCR, Pathogen Detection, Nutrient Source Tracking and calculate Host Fecal Score™.

Mr. Larenas explained that MST answers three major questions relating to fecal pollution in water:

* Where is the pollution coming from?

* Who is responsible?

* How to evaluate BMP effectiveness?

He also walked the Colorado stormwater managers through the formulation of a sampling and testing plan – how sampling sites are selected, when sampling should be conducted, and how many tests should be conducted per sample. The answers depend on historic and current monitoring data. MST does not replace fecal indicator bacteria (FIB) monitoring. It is an additional step to take to clearly identify bacteria sources.  

To better explain the applications of MST, Mr. Larenas cited three projects in Florida, Massachusetts and California. Martin County in Florida used MST to prioritize and rank sites that would have the most effect in lowering human fecal pollution. Geosyntec conducted a project for the Boston Water and Sewer Commission in which they used DNA markers to assess the effectiveness of BWSC’s MS4 IDDE program. Santa Barbara in California used MST to identify pollution sources at their beaches and to measure the impact of their best management practices (BMP).
