Nutrient samples were collected from seven river stations and seven bay stations on October 2nd and 3rd. All bay stations were sampled at the surface and bottom. In the five days prior to sampling, there were 0.03 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 Woonasquatucket River @ Valley St. (TN = 1,530 ppb, TDN = 1,560 ppb, DIN = 1,390). The lowest TN, TDN, and DIN were observed at Pawtuxet River @ Broad St. (TN = 672 ppb, TDN = 491 ppb, DIN = 259 ppb).
Among the bay stations sampled, the highest surface total nitrogen (TN), total dissolved nitrogen (TDN), and dissolved inorganic nitrogen (DIN) were observed at Phillipsdale Landing (TN = 1,270 ppb, TDN = 905 ppb, DIN = 630 ppb). The lowest surface TN was observed at Conimicut Point (449 ppb), while the lowest surface TDN and DIN concentrations were observed at Bullock Reach Buoy (TDN = 215 ppb, DIN = 13 ppb, reflecting minimum detection limits).
The next scheduled sampling date is October 16, 2024.
