About Source Molecular Corporation

  Source Molecular Laboratory  
Source Molecular Corporation is a private commercial laboratory founded in 2002 with a mission to fill the void between source identification research and real-world implementation of the technology. The laboratory is dedicated to offering innovative technology for solving pathogenic water pollution problems through microbial source tracking genetic and molecular techniques. Throughout the years, the Source Molecular microbiology laboratory has analyzed samples for hundreds of industrial plants, watershed management groups, state/federal government agencies, universities and engineering firms making it the leader in the Microbial Source Tracking (MST) industry. By providing commercial MST testing services, Source Molecular assists clients with recreational water quality monitoring and supports Total Maximum Daily Load (TMDL) development and implementation.

Driven by its zeal to provide the highest quality of service, Source Molecular secured a license from the U.S. Environmental Protection Agency (EPA) allowing it to use the MST technology the EPA developed and patented. The laboratory also has an onsite collection of reference fecal samples obtained from throughout the North America, as well as a network of partners with additional fecal samples, which allows it to better validate the performance of the fecal markers. Source Molecular's laboratory has created a database of thousands of internal and external validation tests performed on its suite of existing markers. This dataset allows the laboratory to better select which tests are appropriate for a project based on local concentrations of the markers.

In addition to operating as a commercial laboratory, Source Molecular is devoted to contributing to MST Research and Development and its scientists are co-authors in several major peer-reviewed research publications. Source Molecular has exhibited a history of unprecedented commitment to the commercialization of microbial source tracking services compared to other commercial laboratories in the industry. Source Molecular has begun the process of becoming the only ISO/IEC 17025:2005 accredited MST laboratory in the world.


Services Available

At present, Source Molecular offers tests that can identify and quantify fecal contamination from 13 host sources -- Human, Cattle, Swine, Gull, Goose, Chicken, Dog, Deer, Elk, Horse, Bird, Beaver and Ruminant (see below). 

Clients wishing to identify fecal pollution sources will receive unlimited assistance in crafting appropriate sampling and MST plans.  Shipping kits, including sterile sample bottles, are available so that clients are prepared to sample contaminated waters as soon as the opportunity arises, such as after a rain event.  The Source Molecular shipping kit is also recommended for quality assurance and quality control purposes.  Please see our detailed packing instructions for more information.

Upon sample arrival and analysis, Source Molecular delivers the results of MST tests in 5-10 working days, one of the fastest turnaround times in the industry.  Clients may opt for presence/absence testing or quantification testing to determine the concentration of the host-associated genetic markers in the water samples.  See our sample presence/absence report and our sample quantification report.  Source Molecular recommends conducting two or more tests per water sample in order to strengthen the validity of the results, particularly negative results.  In addition, Source Molecular suggests sampling during both dry and wet events. 

To discuss project pricing and design, please email or call Source Molecular at (786) 220-0379.

Quality Control and Accreditation

Quality control is maintained with the latest scientific laboratory equipment and highly trained, degreed personnel. Source Molecular uses scientifically rigorous (i.e. published and peer-reviewed) molecular analytical methods that enable it to identify with high confidence any contamination, to avoid false positives. The possibility of qPCR inhibition, a common cause of false negative results, is also monitored.

Source Molecular is on its way to becoming ISO/IEC 17025:2005 accredited. It received its pending accreditation notice from the American Association for Laboratory Accreditation (A2LA) indicating that the accreditation process is set to be finalized later this year. Upon completion, Source Molecular will be provided a Certificate and Scope of Accreditation detailing the tests for which the company has been judged competent to perform. This will make Source Molecular the only dedicated Microbial Source Tracking laboratory in the country to be ISO/IEC 17025:2005 accredited and serves as a recognition of its laboratory's quality and high standards.

Reports

The following are examples of reports describing projects that Source Molecular was involved in:
  1. The Gallatin Local Water Quality District (GLWQD) in Montana collected 60 water samples in 2013 from four Bozeman Creek monitoring stations for E. coli bacteria. During September sampling, additional samples were collected and sent to Source Molecular for MST analysis for human and dog. The GLWQD wanted to understand the source(s) of elevated E. coli bacteria in Bozeman Creek. Each sample was analyzed for one dog fecal biomarker and three human fecal biomarkers. MST results suggest human sources are major contributors of fecal pollution to Bozeman Creek, but additional data is needed. The GLWQD noted that the MST results from one sampling event are not conclusive and therefore further MST monitoring is needed in order to craft an appropriate remedy to the problem.

  1. We also helped the San Juan Watershed Group with their Microbial Source Tracking project. They collected weekly water samples from 5 sites on the Animas and San Juan Rivers from April to October in 2013 and 2014. They wanted the water samples to be tested for Human, Cow, Ruminant (deer, elk, cows, sheep), and Bird bacteria sources. In 2014, they sampled the rivers for E.coli and the presence/absence of 5 bacteria source groups. In their final MST report, they concluded that Human and ruminant fecal contamination was found at all 5 sites tested and that human source bacteria is a bigger problem on the San Juan than on the Animas.SJWG February 2015 Meeting Summary
  1. Atkins, the consultant for Charlotte County in Florida, sent us samples from the combined monitoring they were doing on Sunshine Lake/Sunrise Waterway. Specifically, they sent us storm water samples in July and August 2014. We found traces of dog and human bacteroidetes in the August storm water samples. The study is still ongoing. Atkins has recommended that Charlotte County perform an additional assessment to determine what other sources are responsible for the high levels of bacteria in the waterway. Tasks Atkins has performed related to the Sunshine Lake/Sunrise Waterway Study as of October 23, 2014 and Atkins? Revised Interim Report dated August 21, 2014.
  1. The Red Lake Watershed District in Minnesota reported having high E. coli concentrations at some of its long-term monitoring sites. In June 2014, the District tapped us to help them identify if humans or animals were the source of the fecal pollution. At both sampling events, traces of bird fecal matter were consistently detected at the Mud River and Red Lake River sites. The District noted that it made sense at the Red Lake River monitoring sites because of the large numbers of cliff swallows that live under the bridge near Voyageur?s View Campground. Also, high E. coli concentrations seem to occur most frequently when the birds are present, especially during the month of June. Monitoring continues as well as collecting samples for MST analysis.

  1. Upon the recommendation of one of our regular clients, the City of Manhattan Beach sought our help in March 2014 in analyzing the bacteria they found in Well 11A located in Redondo Beach, California. They wanted to know if the bacteria were a product of human fecal contamination. The samples they sent us tested negative in all five tests for human-associated bacteria. This prompted the City of Manhattan to move on and they later determined that the bacteria are likely a product of environmental factors in the groundwater aquifer. Because the City of Manhattan was able to properly eliminate their suspects, they were able to craft a plan that calls for chemical treatment and mechanical well head rehabilitation services to get rid of the bacteria.
  1. Geosyntec Consultants conducted the San Diego River Dry Weather Microbial Source Tracking Study to, among others, identify fecal sources in County MS4 outfalls. The laboratory of the City of San Diego, which performed membrane filtration, sent us samples in April and June 2014. Geosyntec wanted the samples to be analyzed for human, dog, horse, ruminant, cow and pig bio-markers. Some samples tested positive for humans and dogs. Geosyntec noted that the human markers were observed in networks that had homeless encampments. Geosyntec recommends additional monitoring to further confirm the results.
