Nutrient samples were collected from seven river stations and seven bay stations on June 11th. All bay stations were sampled at the surface and bottom. In the five days prior to sampling, there were 0.85 inches of precipitation 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 at Broad St. (TN = 1,090 ppb, TDN = 1,200 ppb, DIN = 863.7). The lowest TN and DIN were observed at Woonasquatucket River at Manton Ave. Bridge (TN = 638 ppb, DIN = 406.4 ppb, average of duplicates). The lowest TDN was observed Moshassuck River @ Footbridge at Mill St. (660 ppb).
Among the bay stations sampled, the highest surface TN was observed at Phillipsdale Landing (1,080 ppb). The highest TDN and DIN were observed at Pawtuxet Cove (TDN = 963 ppb, DIN = 654.7 ppb). The lowest surface TN, TDN, and DIN were observed at Edgewood Shoal (TN = 597 ppb, TDN = 176 ppb, DIN = 13 ppb, reflecting minimum detection limits for DIN)
The next scheduled sampling date is June 25th, 2025.
