Nutrient samples were collected from ten river stations and eight bay stations on August 7th. Edgewood Shoal was sampled at the surface and bottom; all other bay stations were sampled at the surface only. In the five days prior to sampling, there were 0.59 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) concentrations were observed at Blackstone River @ Stateline (TN = 1,250 ppb, TDN = 1,80 ppb, DIN = 970 ppb). The lowest TN was observed at Runnins River @ River Rd (743 ppb), while the lowest TDN and DIN were observed at Palmer River @ Rt 6 (TDN = 360 ppb, DIN = 13 ppb, average of duplicates).
Among the bay stations sampled, the highest surface total nitrogen (TN), total dissolved nitrogen (TDN), and dissolved inorganic nitrogen (DIN) were observed at Pawtuxet Cove (TN = 1,110 ppb, TDN = 944 ppb, DIN = 683 ppb, average of duplicates). The lowest surface TN was at Conimicut Point (549 ppb), while the lowest surface TDN and DIN concentrations were observed at Bullock Reach Buoy (TDN = 322 ppb, DIN = 132 ppb).
The next scheduled sampling date is September 4, 2024.
