Source Molecular Attends 12th SESWA Conference in Kentucky

The Kentucky Division of Water shared their statewide approach to Pathogen Total Maximum Daily Loads at the 12th Annual Regional Stormwater Conference of the Southeast Stormwater Association (SESWA) held in Louisville from October 11 to 13, 2017.

Source Molecular Corporation had an exhibit booth at the SESWA Conference, which focused on stormwater solutions in Region 4. Attendees had access to a wide array of technologies and strategies to address challenges in stormwater management across the southeast.

Lauren McDonald, environmental scientist at the Kentucky Division of Water, noted that there are 331 Kentucky waters listed for pathogen impairment. Given the division’s limited staff, she said, it could take decades to complete watershed TMDLs. That is why they are switching from a watershed basis to a “segment” basis. This will reduce the development of bacteria TMDLs to approximately six years.

MST Can Help With TMDLs

Source Molecular, which provides microbial source tracking (MST) services, has been involved in TMDL projects. MST helps water managers identify the sources of fecal bacteria in a waterbody. MST can also tell them which of the sources are likely the most dominant in the watershed of interest. Therefore, MST can help water managers plan for a more effective remediation and reduce bacteria levels in a watershed.

Bacteria in the watersheds can come from a variety of sources. Source Molecular can identify 12 sources — Human, Cattle, Swine, Gull, Goose, Chicken, Dog, Elk, Horse, Bird, Beaver and Ruminant. Its representative met with government administrators, regulators, environmental engineers and consultants to explain the advantages of MST in TMDL development.

Source Molecular also shared its Pathogen Detection service, which targets DNA and RNA of bacteria and viruses that actually cause illness in humans. Pathogen Detection provides further analysis of fecal indicator bacteria to determine if they pose a threat to human health.

The SESWA Conference also included a discussion by Dr. Doug Durbin, Chief Scientist at Brown and Caldwell, on “The Long and Winding Road of Nutrient Criteria Development”. Source Molecular offers Nutrient Source Tracking (NST), which tells water managers who’s responsible for the nutrient pollution.
