MyRWA is collaborating with the Massachusetts Department of Environmental Protection (MA-DEP), United States Environmental Protection Agency (US-EPA), Massachusetts Water Resources Authority (MWRA) and the United States Geologic Survey (USGS) to develop a stronger understanding of flow conditions and nutrient loads in the Mystic River watershed. This autosampler is capturing samples as triggered by the flow measured at the USGS stream gauge on the Aberjona River. At every 86,400 cubic feet of flow, the machine takes a sip of 100 ml of river that is added to a large composite sample. MyRWA expects to have 5 autosamplers running throughout the watershed in 2016.
