The Palmer River, which flows across the Massachusetts (MA) and Rhode Island (RI) state border, is a major second order tributary in the Narragansett Bay watershed. The upper freshwater reaches of the Palmer River begin in Rehoboth, MA with the east and west branches of the river extending into Seekonk and Swansea, MA. Head of tide for the Palmer River is at the outlet of the Shad Factory Pond Dam, downstream of which the Palmer River joins with the Barrington River at Tyler Point in RI to form the Warren River before emptying into the Narragansett Bay. While still dominated by forest, the Palmer River watershed contains significant agriculture and development and faces increasing development pressure. Moreover, multiple studies by both states since 1992 have repeatedly documented continuing impairments in the Palmer River due to elevated levels of fecal indicator bacteria as well as total suspended solids (TSS) and nutrients (nitrogen and phosphorus (RIDEM, 2002 (PDF) (103 pp, 3.7 MB); ESS Group Inc, 2004 (PDF) (54 pp, 1.8 MB)).

These studies led to the inclusion of the Palmer River watershed in the National Water Quality Initiative (NWQI), a joint effort between EPA/state nonpoint source programs and the U.S. Department of Agriculture to abate fecal contamination through the installation of agricultural conservation practices or best management practices (BMPs). Water quality sampling since 2012 by the Massachusetts Department of Environmental Protection (Mass DEP), the Rhode Island Department of Environmental Management (RIDEM), and US EPA Region 1 has been correlated with the installation of agricultural BMPs to enable these agencies to monitor the effectiveness of remediation efforts. However, until this project, much of the water quality data collected have yet to be evaluated for trends, and the current status of water quality and the effectiveness of agricultural BMP implementation work in the watershed were unknown. To address this gap, beginning in 2017, samples were collected for ribonucleic acid (RNA) microarray analysis using PhyloChip and are awaiting analysis. The PhyloChip is a cutting-edge analytical tool that uses specific genetic markers to determine the relative contribution to fecal contamination by different sources (i.e. human, cow, bird, etc.).

The purpose of the project was to assist US EPA Region 1 with: (1) developing recommendations for use of the PhyloChip to maximize the ability to identify fecal contamination sources with limited resources; (2) analyzing water quality trends in the Palmer River watershed using existing water quality data, geospatial information, and summary papers; and (3) assessing the impact that changing land use is expected to have in the Palmer River watershed and providing recommendations for reducing the impacts of land development on water quality.

Results will be used by US EPA Region 1, state agencies, and local municipalities to 1) revise the current water quality monitoring program, including site selection and parameters (e.g., use of PhyloChip), 2) apply water quality monitoring strategies for use of PhyloChip as a source tracking method in other regional watersheds in the Southeast New England Program (SNEP), 3) determine the water quality status of the Palmer River (e.g., improving, degrading) and its relationship to agricultural BMPs on the landscape, 4) better inform future effectiveness and placement of agricultural BMP work in the watershed, and 5) review local land use regulations and their impacts on water quality.
