Nutrient samples were collected from seven river stations and eight bay stations on September 3rd. All bay stations were sampled at the surface. In the five days prior to sampling, no precipitation was recorded at T.F. Green.
Among the river stations sampled, the highest total nitrogen (TN) was observed at Pawtuxet River @Broad Str. (TN = 1,450 ppb). The highest total dissolved nitrogen (TDN) and dissolved inorganic nitrogen (DIN) were observed at Blackstone River @ Stateline (TDN = 1,940 ppb, DIN = 1,467.7 ppb). The lowest TN, TDN, and DIN were observed at Moshassuck River @ Higginson Ave (TN = 598 ppb, TDN = 703 ppb, DIN = 454.4 ppb).
Among the bay stations sampled, the highest surface TN was observed at Phillipsdale Landing (1,220 ppb). The highest TDN and DIN were observed at Pawtuxet Cove (TDN = 969 ppb, DIN = 729.3). The lowest surface TN and TDN were observed at Bullock Reach (TN = 453 ppb, TDN = 162 ppb). The lowest surface DIN was observed at five of the eight bay stations (13 ppb, reflecting minimum detection limits for DIN).
The next scheduled sampling date is September 17th, 2025
