Nutrient samples were collected from seven river stations and seven bay stations on March 18th. In the five days prior to sampling, 1.75” 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 Blackstone River @ Slater Mill (TN = 902 ppb, TDN = 1,210 ppb, DIN = 559 ppb). The lowest TN, TDN and DIN were observed at Pawtuxet River @ Broad St. (TN = 759 ppb, TDN = 657 ppb DIN = 461 ppb).
Among the bay stations sampled, the lowest TN, TDN and DIN were observed Phillipsdale Landing Surface (TN = 999 ppb, TDN = 981 ppb, DIN = 693 ppb). The lowest TN, TDN and DIN were observed at Bullock’s Reach Bottom (TN = 429 ppb, TDN = < 100 ppb DIN = 8.75 ppb).
The next scheduled sampling date is April 1st, 2026.
