Description:The key objective of this Phase I project is to develop a novel dual-wavelength radiometric fluorescence method and sensor for the detection of coliform bacteria in water samples. The radiometric technology will be rapid, robust, and suitable for the development of online sensors for monitoring the effluents of urban stormwater and sewage treatment plants. This novel approach, unlike previous single-wavelength intensity-based methods, will be highly immune to light source and detector instabilities, temperature effects, optical density, and turbidity variability in the sample, spurious quenching, and photobleaching. In contrast to current methods that take 24 hours or more to generate results, the proposed technology will provide reliable results in minutes to hours, depending on bacterial concentration.
The overall potential market for coliform testing of water encompasses several segments: drinking water, municipal sewage, coastal fisheries, shellfish aquaculture, and beach and recreational waters. Products will include a portable instrument, reagent kits, and online sensors.
