Table 2 Surface water standardized major axis regression results for flow way 1 (FW 1) and FW 3 within Stormwater Treatment Area-2 for inflow, mid, outflow, and entire FW (ALL) regions. Stoichiometric comparisons include dissolved organic carbon to total phosphorus (DOC:TP), dissolved organic carbon to total nitrogen (DOC:TN), and total nitrogen to total phosphorus (TN:TP)
