PROMOTE SUCCESSFUL RESTORATION <br />■ Stable DO can promote coupled nitrification -denitrification (i.e., <br />removal of nitrogen from the system). <br />■ Expanding areas of hypoxia inhibit nitrification, an essential yet <br />often limiting step in biological nitrogen removal. <br />■ Expanding areas of hypoxia decrease sorption capacity of <br />sediments leading to higher concentrations of dissolved <br />phosphorus. <br />January 18, 2022 Item S.D. <br />MEASURABLE DECREASE IN HYPDXIA & NUTRIENT FLUXES? <br />Dredging _8k -Capping: <br />Decrease N and P fluxes + SOD <br />Sediment oxygen demand_: <br />Sandy sediments: 100 mg/m2/hr <br />Muddy sediments: >300 mg/.-n2/hr <br />Tracking DO is an effiaent way to <br />evaluate performance and quantify <br />success. <br />
