Nutrient samples were collected from 15 local river stations on January 25th. Bay sampling was cancelled due to a small craft advisory. In the five days prior to sampling, 1.48 inches 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) concentrations were observed at Ten Mile River @ Central Ave. (TN = 1,930 ppb, TDN = 1,980 ppb, DIN = 1,640 ppb). The lowest TN was observed at Palmer River @ Rt. 6 (TN = 624 ppb). The lowest TDN was measured in one of the duplicate samples from Coles River @ Milford Rd. (649 ppb), while the other duplicate was slightly higher at 657 ppb; TDN was similarly low at Palmer River @ Rt. 6 (652 ppb). The lowest DIN was observed at Coles River @ Milford Rd. (DIN = 221 ppb, average of duplicates).
Data from additional sampling dates (typically every two weeks) are pending analysis and writeup.
