Abstract
 Color Infrared Survey for Identification of Failing On-Site Treatment Systems Track: Water Resources Author(s): William Roper, Alfonso Blanco Color infrared (CIR) photography was used to identify failure of these on-site wastewater treatment systems within a large geographical area without depending on field surveys, which require time, personnel, and money. Once the CIR photos are obtained by flying a small commercial plane with a recording device, experienced analysts using the remotely sensed data, GPS and GIS can identify and georeference the failed systems. Investigations show that this approach reduces time, labor, and materials for identifying septic system failures.
