Nutrient samples were collected from thirteen river stations on May 1st. In the five days prior to sampling, there were 0.13 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 Ten Mile River @ Central Ave (TN = 1,340 ppb, TDN = 1,260 ppb, DIN = 946.2 ppb). The lowest TN and TDN were observed at Moshassuck River @ Higginson (TN = 530 ppb, TDN = 436 ppb, each being duplicate samples taken at the site). The lowest DIN were observed at Coles River @ Milford Rd. (DIN = 58 ppb).
Among the bay stations sampled, the highest surface TN, TDN, and DIN were observed at Phillipsdale Landing (TN = 1,000 ppb, TDN = 836 ppb, DIN = 663 ppb). The lowest surface TN were observed at Conimicut Point (TN = 544 ppb), while lowest surface TDN and DIN were observed at Edgewood Shoal (TDN = 124 ppb, DIN = 17 ppb). Chlorophyll a concentrations at the surface bay stations averaged 19.62 μg/L overall with a maximum of 35.12 μg/L at the Bullock Reach Buoy.
The next scheduled sampling date is May 14, 2024.
