Nutrient samples were collected from six river stations and seven bay stations on August 19th. All bay stations were sampled at the surface and bottom. In the five days prior to sampling, 0.13” of precipitation were recorded at T.F. Green.
Among the river stations sampled, the highest total nitrogen (TN), total dissolved nitrogen (TDN), and dissolved inorganic nitrogen (DIN) were observed at Pawtuxet River @ Broad St. (TN = 1,600 ppb, TDN = 1,240 ppb, DIN = 956.2 ppb). The lowest TN was observed at Moshassuck River @ Footbridge at Mill St. (749 ppb). The lowest TDN and DIN were observed at Moshassuck River @ Higginson Ave (TDN = 685 ppb, DIN = 547.0 ppb).
Among the bay stations sampled, the highest surface total nitrogen (TN) was observed at Phillipsdale Landing (2690 ppb). The highest surface total dissolved nitrogen (TDN) and dissolved inorganic nitrogen (DIN) were observed at Pawtuxet Cove (TDN = 885 ppb, DIN = 535.8 ppb). The lowest surface TN was observed at Bullock Reach (523 ppb). The lowest surface TDN was observed at Edgewood Yacht Club (186 ppb). The lowest DIN was observed at Phillipsdale Landing (38.0 ppb).
The next scheduled sampling date is September 2nd, 2026.
