Water-quality data from the Providence Water Supply Board for tributary streams to the Scituate Reservoir (ver. 4.0, December 2025)
Water-quality data were collected by Providence Water, formerly referred to as Providence Water Supply Board (PWSB), from tributaries in the Scituate Reservoir drainage area, October 1, 2017 through September 30, 2024 (water years 2018 through 2024). Water-quality samples were collected by the PWSB either monthly or quarterly at fixed stations on 38 tributaries in the Scituate Reservoir drainage area, Rhode Island. These data were used to calculate instantaneous loads and yields of constituents in reports by the U.S. Geological Survey. Water-quality samples were collected following a strict sampling schedule so that water-quality samples would be representative of various weather conditions. Samples were analyzed at the PWSB water-quality laboratory at the P.J. Holton Water Purification Plant in Scituate, Rhode Island. Water-quality properties and constituent concentrations were measured by using unfiltered water samples. These water-quality properties included pH, alkalinity, color, turbidity, and concentrations of chloride, nitrite, nitrate, orthophosphate, and bacteria (Escherichia coli [E. coli] and total coliform). This data release will be updated to append additional water-quality data collected by the PWSB.
