This image showed evidence of water contamination marked by fluorescent dye in Crater Lake National Park, Oregon. Fluorescent dye that had been added to a toilet, was shown to be spilling out of the sewer manhole, which contaminated the drinking water supply, and found to be the source of an outbreak of gastrointestinal (GI) illness caused by toxigenic E. coli.
