Water Quality


The Saugatucket River, with its long history of use in industry and urban setting, unfortunately has impaired water quality. Stormwater runoff from impervious surfaces near the river (parking lots, roofs, sidewalks, etc.) carries with it bacteria from pet and other animal waste, fertilizers, pesticides/herbicides, oils from vehicles, road salt, and many other pollutants.

Richard Youngken measures Secchi depth, an indicator of water clarity, in Saugatucket Pond.

The Saugatucket River at the dock next to the public parking lot off Main St. has been monitored for water quality by volunteers with the University of Rhode Island Watershed Watch (URI WW) program and Salt Ponds Coalition for many years. Other sites in the river were also monitored years ago, but haven’t been for some time. FOS has restarted monitoring on two of these dormant sites: Saugatucket Pond and the Saugatucket River at Saugatucket Rd.

The data from all of this monitoring can be accessed through the Google Map below, which also shows the locations of water quality testing sites of the Wood-Pawcatuck Watershed Association (blue placemarks), Salt Ponds Coalition (green placemarks), Save the Bay (pink placemarks), and in the Coastal watershed (yellow placemarks). Click on a placemark to access information pages (PDF format) with links to analytical data for each site (except perhaps the most recent year if it has not yet been received/processed). All samples were analyzed and data were provided by URI WW. Friends of the Saugatucket hopes to resume monitoring of additional dormant sites as funding allows.
