The Environmental Protection Agency has developed a list of materials defined as hazardous substances based on their aquatic toxicity. In addition, certain materials have been designated as 'priority pollutants.' Often, a spill of toxic materials into a moving water stream can occur without the spiller being aware, or without the spiller notifying authorities. Accordingly, a system was needed to detect the presence of hazardous toxic materials in streams and rivers. This need has been filled by providing a spill alarm system, which was designed, fabricated, and tested prior to delivery. It consists of nonselective detection components which together serve to detect all the materials on the designated hazardous materials list, and the priority pollutants. The system was mounted on an automotive trailer and delivered to the Oil and Hazardous Materials Spills Branch in Edison, New Jersey.
