We all know that dogs can help humans by using their amazing scenting abilities, such as finding missing persons and detecting bombs, narcotics, and arson materials. How they do it and how accurate they are, however, has been difficult to study scientifically. ECS has been fortunate to attract the attention of the scientific community to study our canines and their abilities to locate and source track human sewage.
The first study was funded and published by the Water Environment Research Foundataion (WERF) and conducted by the City of Santa Barbara Creeks Division and the University of California, Santa Barbara in 2010. Side-by-side lab testing for bacterial, chemical, and human DNA markers was done for the locations investigated by the canines. The final research report found:

A follow up to the original WERF study was published in Water Environment Research in June 2014. That publication found:
Many ECS clients are now conducting side-by-side sample collection and lab testing for bacterial, chemical, and/or human DNA indicators at key sites where sewage presence was detected by the ECS canines. The combined results can provide confirmation of sewage presence and its health risk potential based on amount of fecal indicator bacteria and other measures. The results can also be a powerful tool for locating illicit discharge sources that are "invisible", such as leaking underground pipes and faulty septic system leaching, and providing more comprehensive information for decision making.

The uniqueness of what ECS does and the sight of our talented and adorable canines often attracts the media to observe and report on our activities. Here are a few of our more recent news articles and videos.
Since its founding in 2009, ECS has completed nearly 100 sewage detection/source tracking projects in 16 different states plus Washington D.C. and several hundred Ship and Sniff samples from 13 different states.
Here is a list of the states we have worked in or done Ship and Sniff sample scenting for over the past 10 years. We have provided services to small, medium, and large municipalities, state environmental quality agencies, environmental and water quality organizations, Riverkeepers, Native American tribes, environmental consulting companies, and lake associations.
