The Neponset River Watershed Association monitors water quality around the Neponset River Watershed in order to catch any water pollution problems and start the process of cleaning them.

NepRWA runs the Citizen Water Monitoring Network program ("CWMN" - pronounced "swimmin"), and also a hot-spot sampling program. 

NepRWA trains CWMN Volunteers to monitor water quality around the Neponset River Watershed, in streams, ponds, lakes and the River. CWMN data help NepRWA to pin-point water quality problem areas for follow-up. 

NepRWA Environmental Scientist Bill Guenther chooses particular problem sites identified through the CWMN program, for further testing. At these "hot spot" sites, Bill tests for the presence of "optical brighteners". Optical brighteners indicate that untreated wastewater is entering these water bodies.
