In situ detection of sewage pollution and its sources in aquatic ecosystems

Abstract

Sewage discharges pose a threat to human, animal, and ecosystem health, and disrupt recreational pursuits like fishing and beachgoing. Environmental Canine Services, LLC selects, trains and fields dog-handler teams to source track sewage from leaking sewer lines, faulty septic systems, and illicit pipe connections. The teams cost-effectively locate or isolate sewage discharge sources far more quickly than standard methods (e.g., in hours/days). Information about the origins of this application, the types of dogs sought and used, elements of handler training and testing, and types of stakeholders partnered with to date is also provided. Recommendations are made for further research into the scent components of this target, and to better assess individual dog performances, with an aim of promoting greater use of this effective but still underutilized application.
