Broadband toxicity sensing for rapid surveys of drinking water storage facilities

Nekton Research has developed a novel, broad-band water toxicity detector and sampler for use on the Nekton Ranger AUV. This system can quickly survey drinking water reservoirs, in 3D, and provide early warning of toxic contamination. The novel element of the detector is an array of live clams that function as "canaries in a coal mine". When these highly sensitive filter feeders encounter water they deem toxic, they snap their shells shut and close down their feeding activities - a rapid reaction that can be utilized to trigger AUV response. Initial field trials and sensor characterization will be described as well as homeland security applications
