The map shows status and trends at four stations in the Lower
Patuxent River for nitrite (NO2-) and nitrite plus nitrate (NO2-
+ NO3-) fluxes (observed data).
Nitrite plus Nitrate (NO2- + NO3-)
The current status (average of 1996-1998 data) of nitrite plus nitrate fluxes at the four
SONE stations in the Patuxent River is indicated above. Ideally, we want to see high
NO2- + NO3- fluxes for two reasons: (1) High
fluxes mean that NH4+ continues to evolve and (2) DO is required for
this process to occur, therefore there must be plenty of DO present. Among the four SONE
stations in the Patuxent River, St. Leonard Creek (STLC) was considered good. Buena Vista
(BUVA), Broomes Island (BRIS) and Marsh Point (MRPT) were found to be poor. Nitrite plus
Nitrate is part of the nitrification process that helps
restore estuarine systems.
