“…(2)) assigns a larger weight to smaller concentrations and might result in more conservative DT 50 values (Beulke and Brown, 2001), this approach was chosen to allow for the determination of outliers in the dataset. Removal rate constants were indicated as b 0.001 if compounds showed no decrease in concentration over the duration of the experiment (also reflected by a poor coefficient of determination R 2 ) or if λ turned negative (Burke et al, 2014). The firstorder equation was considered acceptable for R 2 values above 0.63.…”

“…Though several field studies from MAR sites investigated redox-dependent attenuation of certain TOrC (Drewes et al, 2003;Heberer et al, 2008;Massmann et al, 2006;Schmidt et al, 2004;Wiese et al, 2011), only limited knowledge is available from controlled laboratory-scale studies that systematically investigated and compared the influence of different redox conditions on biotransformation of TOrC in the subsurface (Baumgarten et al, 2011;Burke et al, 2014;Suarez et al, 2010). Burke et al (2014) compiled the redox dependent degradation behavior of 27 wastewater-derived TOrC in groundwater based on several studies using tank aeration experiments with no soil present.…”

This study developed relationships between the attenuation of emerging trace organic chemicals (TOrC) during managed aquifer recharge (MAR) as a function of retention time, system characteristics, and operating conditions using controlled laboratory-scale soil column experiments simulating MAR. The results revealed that MAR performance in terms of TOrC attenuation is primarily determined by key environmental parameters (i.e., redox, primary substrate). Soil columns with suboxic and anoxic conditions performed poorly (i.e., less than 30% attenuation of moderately degradable TOrC) in comparison to oxic conditions (on average between 70-100% attenuation for the same compounds) within a residence time of three days. Given this dependency on redox conditions, it was investigated if key parameter-dependent rate constants are more suitable for contaminant transport modeling to properly capture the dynamic TOrC attenuation under field-scale conditions. Laboratory-derived first-order removal kinetics were determined for 19 TOrC under three different redox conditions and rate constants were applied to MAR field data. Our findings suggest that simplified first-order rate constants will most likely not provide any meaningful results if the target compounds exhibit redox dependent biotransformation behavior or if the intention is to exactly capture the decline in concentration over time and distance at field-scale MAR. However, if the intention is to calculate the percent removal after an extended time period and subsurface travel distance, simplified first-order rate constants seem to be sufficient to provide a first estimate on TOrC attenuation during MAR.

“…The estimated degradation rate constants of primidone also show a high variation coefficient (C V = 0.82). Since primidone was found to be persistent in all previous studies Hass et al, 2012;Burke et al, 2014a;Henzler et al, 2014), we refrain from linking its degradation behavior to the potentially prevailing redox conditions below the pond. For most of the degrading compounds the estimated rate constants of this study were considerably higher than reported in previous studies, even though prolonged aerobic conditions, which generally lead to higher degradation rates for many organic compounds (Stuyfzand et al, 2007;Kunkel and Radke, 2008;Xu et al, 2009;Wiese et al, 2011;Fang et al, 2012;Hoppe-Jones et al, 2012), were presumably not present.…”

“…For example, the biochemical and chemical oxidation demands of substrates were, respectively, lower than 15 and 25 mg/L (Akbarzadeh et al 2015). However, the inhibitory effects of exotic compounds responsible for inhibiting aeration are neglected (Burke et al 2014). The aeration coefficients were calculated with respect to the completely mixed condition using the first-order kinetic reactions.…”

Enhancement of surface water quality using trading discharge permits and artificial aeration

Water quality trading (WQT) is a strategy for surface water quality management. This study focused on finding the optimal waste load allocation by WQT framework based on the concentrations of BOD and dissolved oxygen (DO) in Sefidrud River. It also assessed the consequences of using artificial aeration on trading discharge permits. For these purposes, river was simulated by Qual2kw. Two checkpoints were considered for monitoring the upstream (Sangar) and downstream (Caspian). Sensitivity analysis was carried out to find the impact factors of each emission sources. The required total maximum daily loads (TMDLs) were determined through simulation results. It predicted that the concentrations of ultimate BOD in both Sangar and Caspian stations may decrease from 3.6 and 8.1 mg/L, respectively, to 2.1 mg/L. Conversely, DO may increase from 5.8 and 0.9 mg/L to 7 and 3.7 mg/L, respectively. This could solely save 7 % of total treatment costs in comparison with the conventional command and control (C&C) policy. WQT may increase the revenues to 21 %. However, this could not provide enough flexibility and robustness in regard to the permit pricing and profits attained by stakeholders. Artificial aeration was considered as an improvement solution in the second scenario. The experimental results of hydroponic systems and hydraulic river simulation by CCHE2D showed that 0.25 day -1 can be added to the aeration coefficients. This modified TMDLs and impact factors thoroughly. Results verified that this approach may increase the revenues of TMDLs and discharge permit market, respectively, to 17 and 30 %. Permits can also be sold with higher prices and stakeholders may attain considerable profits. Consequently, the integration of artificial aeration with WQT was recommended for surface water quality enhancement.
