“…Although the potential for oxic degradation of DOC was described in previous column studies (e.g., [11,19]) and field studies [2], only minor DOC removal is observed in this study. Since the local tap water used as influent originates from the bank filtration site after more than 50 days of subsurface treatment, the DOC concentrations of 4-5 mg/L are already low and no further oxic conversion is expected within the comparably short residence time in the cores.…”

“…Heterogeneous behaviors have been reported for benzotriazole, with removals ranging from 75%-90% in bank filtration [6], and only poor removals in column experiments with lake sediments [11]. In the present study, no remarkable eliminations of benzotriazole were observed in the different cores.…”

“…Although a degradation of carbamazepine was observed in the presence of high POC contents [31] and iron reducing conditions [5], carbamazepine was often found to be persistent [11,32,33]. Accordingly, carbamazepine was proposed as an indicator compound for anthropogenic influences in the water cycles [30].…”

“…Sulfamethoxazole was found in field studies to be better degraded under anoxic conditions (absence of oxygen) [2,4]. Diclofenac and formylaminoantipyrine were reported to be better degraded under oxic conditions [5,11]. The specific redox conditions are mainly determined by microbial processes [3].…”

Bank filtration (BF) and soil aquifer treatment (SAT) are efficient natural technologies in potable water reuse systems. The removal of many organic micro-pollutants (OMPs) depends on redox-conditions in the subsoil, especially on the availability of molecular oxygen. Due to microbial transformation of particulate and dissolved organic constituents, oxygen can be consumed within short flow distances and induce anoxic and anaerobic conditions. The effect of accumulated particulate organic carbon (POC) on the fate of OMPs in BF and SAT systems is not fully understood. Long-term column experiments with natural sediment cores from the bank of Lake Tegel and from a SAT basin were conducted to investigate the impact of accumulated POC on dissolved organic carbon (DOC) release, on oxygen consumption, on mobilization of iron and manganese, and on the elimination of the organic indicator OMPs. The cores were fed with aerated tap water spiked with OMPs to exclude external POC inputs. Complete oxygen consumption within the first infiltration decimeter in lake sediments caused mobilization of iron, manganese, and DOC. Redox-sensitive OMPs like diclofenac, sulfamethoxazole, formylaminoantipyrine, and gabapentin were eliminated by more than 50% in all sediment cores, but slightly higher residual concentrations were measured in effluents from lake sediments, indicating a negative impact of a high oxygen consumption on OMP removal.

“…This is especially important with regard to substances like carbamazepine, benzotriazole, and diclofenac. These substances are known for their low degradability in the environment and are, therefore, very persistent in riverine sediments (Burke et al 2014;Kunkel and Radke 2012;Lahti and Oikari 2011;Löffler et al 2005) where they can accumulate. Triebskorn et al (2007) have already shown that environmentally relevant concentrations of metoprolol, diclofenac, and carbamazepine can lead to severe tissue lesions in rainbow trout.…”

In order to evaluate surface water and the sediment quality of rivers connected to wastewater treatment plants (WWTPs) with different treatment technologies, fish embryo tests (FET) with Danio rerio were conducted using native water and sediment samples collected upstream and downstream of four WWTPs in Southern Germany. Two of these WWTPs are connected to the Schussen River, a tributary of Lake Constance, and use a sand filter with final water purification by flocculation. The two others are located on the rivers Schmiecha and Eyach in the area of the Swabian Alb and were equipped with a powdered activated carbon stage 20 years ago, which was originally aimed at reducing the release of stains from the textile industry. Several endpoints of embryo toxicity including mortality, malformations, reduced hatching rate, and heart rate were investigated at defined time points of embryonic development. Higher embryotoxic potentials were found in water and sediments collected downstream of the WWTPs equipped with sand filtration than in the sample obtained downstream of both WWTPs upgraded with a powdered activated carbon stage.

Managed aquifer recharge of aerobic water into deep aquifers often induces the oxidation of pyrite, which can lead to groundwater acidification and metal mobilization. As circumneutral pH is often maintained by the dissolution of sedimentary calcite or high injectant alkalinity little attention is generally paid to potential alternative pH buffering processes. In contrast, this study analyzed water quality evolution from a 2 year long groundwater replenishment trial in an anaerobic, mostly carbonate free aquifer. While injection of aerobic, very low salinity water triggered pyrite oxidation, the comprehensive field data showed that in many aquifer zones pH was buffered without substantial release of inorganic carbon. A numerical analysis was performed to test and evaluate different conceptual models and suggested that either proton buffering or the dissolution of aluminosilicates, or a combination thereof, can explain the observed, rapid buffering at locations where carbonates were absent. In contrast to many previous managed aquifer recharge [MAR) studies, the oxidation of sedimentary pyrite by nitrate was found to be of minor importance or negligible. The study also highlights that the depositional history of the aquifer, and the associated differences in mineralogy and geochemistry, need to be considered when estimating groundwater quality evolution during the injection of various water types for aquifer replenishment or other management purposes. ] describe sequential buffering during ongoing pyrite oxidation in a carbonate-bearing mine waste. After the initial consumption of primary and secondary carbonates (calcite and siderite), they observed the dissolution of previously precipitated gibbsite at pH 4.9-5.2, and subsequent ferrihydrite dissolution at pH < 4.5. Salmon and Malmstr€ om [2004] found that the pH of 4.9 in the groundwater of a carbonate-free mine waste deposit could largely be explained by a balance of acid generation by pyrite oxidation and acid consumption by chlorite and ferrihydrite dissolution.
