Source Molecular Presents at Two Back-to-Back Ohio Conferences

Source Molecular Corporation gave presentations at 38th International Symposium of the North American Lake Management Society (NALMS) and the 47th Annual Water Management Association of Ohio (WMAO) Conference both held at the Duke Energy Convention Center in Cincinnati, Ohio.

The NALMS Symposium was held October 30 to November 2, 2018, and was hosted by the Ohio Lake Management and Indiana Lakes Management societies. Source Molecular’s Chief Executive Officer, Mauricio Larenas, discussed “Evidence-Based Guidelines for Microbial Source Tracking Projects.”

Held in conjunction with NALMS was the WMAO conference, which took place on October 31, 2018. Its theme was “Innovations in Water Resource Management.” Mr. Larenas explained how to leverage DNA technology to enhance water quality.

Both presentations focus on the advantages of microbial source tracking (MST) in bacteria impairment projects. MST is useful when bacteria sources are unknown. In order to craft effective remediation plans, water managers must determine what’s causing the bacteria levels to rise and where it is coming from.

Traditional methods use fecal indicator bacteria (FIB) in water quality monitoring. But water managers cannot effectively assess fecal contamination using FIB particularly in areas where multiple sources exist. MST complements FIB by providing more data about bacteria sources.

Unique DNA sequences of host-associated microorganisms or MST markers 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.

One of the projects that Mr. Larenas cited was the first ever effectiveness assessment of MS4 Illicit Discharge Detection and Elimination (IDDE) program that GeoSyntec Consultants did using DNA markers. GeoSyntec recommended new IDDE procedures for the Boston Water and Sewer Commission (BWSC) to implement. They include the continued use of DNA markers to measure program effectiveness. GeoSyntec believes this will greatly reduce bacteria at outfalls and take the City of Boston closer to compliance with their Total Maximum Daily Load (TMDL).
