Missed connections identification app and tool

The use of optical brighteners has been previously established as a low cost way to diagnose missed connections. Use of UV light to identify the presence of these optical brighteners in watercourses in combination with a mobile device and mapping application and GIS data can help locate missed connections and remedy them. Using a simple UV filter attachment for a smart phone and citizen-science volunteers, indicator signals for missed connections can be easily recorded and combined with existing geospatial data to locate the source of missed connections. This approach could also e used to map other sources of similar pollution such as the locations of septic tanks.
