Abstract

Dissolved oxygen-based metabolism was explored as a proxy of function and a potential indicator of nutrient attenuation in stormwater treating green infrastructure named the Anvil Way Compensation Basin (AWCB) in Perth, Western Australia. Dissolved oxygen was monitored at 10 min intervals at the inlet, middle and outlet of the system. Metabolism due to storm perturbation increased after some storm events in the green infrastructure. The post-event metabolism was usually higher in the system compared to that of pre-event metabolism. Metabolism under the pre-event conditions in the AWCB was correlated with increased solar exposure, water temperature and antecedent der days. After the events, the observed correlations disappeared as changes in constructed wetland volume, flow rate and hydraulic retention time re-set the system. The positive metabolism due to perturbation occurred when the post-event metabolism was higher than the pre-event metabolism, and the negative metabolism occurred when the scenario was opposite. It was assumed that nutrients could be attenuated or released in the constructed wetland due to autotrophic or heterotrophic processes. These processes use dissolved oxygen and provide a metabolic signature. The positive metabolism showed a linear link with attenuation of nutrients including ammonium, nitrate, total nitrogen, filterable reactive phosphorus, dissolved inorganic carbon and dissolved organic carbon. Autotrophic microbial processes likely consumed or converted nutrients to simpler compounds and positive metabolism took place. Therefore, data supported the concept that microbial processing of nutrients or constructed wetland function could be assessed using a proxy indicator of metabolism. It is envisioned that through a better understanding of the variability of constructed wetland function during storm events, this study will help support the design of improved urban water systems for the protection of the downstream water quality.
