“…The low removal efficiency of this compound in the HF wetland (25 ± 45%) suggests that fully aerobic conditions might be important for its degradation, in agreement with previous studies [8,25]. The sweetener sucralose, which has been shown to be highly recalcitrant during biological treatments [22,36,37], was not degraded in any of the CWs. Finally, the FWS wetland exhibited limited removal of all the investigated PPCPs with the highest one observed for caffeine and sulfamethoxazole (about 25%), being in agreement with earlier sampling campaigns [27].…”

The elimination of organic carbon, nitrogen, five emerging organic contaminants (EOCs) and fluorescence signature was evaluated in two treatment lines comprising different constructed wetland (CW) configurations: (i) partially saturated vertical subsurface flow (SVF) wetland (treatment line 1) and (ii) unsaturated vertical subsurface flow (UVF), horizontal subsurface flow (HF) and free water surface (FWS) wetlands in series (treatment line 2). Results showed important differences between the different CW configurations. The highest removal of BOD5 (81%), COD (67%), TOC (72%) and fluorescing organic matter were observed in the UVF wetland, whereas the HF and FWS wetlands were the most efficient units for total nitrogen removal (60 and 69%, respectively).The SVF wetland showed a greater performance in the reduction of total nitrogen than the UVF bed (52 vs 35%). In addition, the SVF wetland exhibited a higher removal of the EOCs caffeine (95 vs 90%), trimethoprim (99 vs 87%) and sulfamethoxazole (64 vs 4%), as opposed to DEET (34 vs 63%), whose removal was superior in the UVF unit. Sucralose was negligibly removed in all the CWs. PARAFAC analysis of fluorescence measurements revealed that the proteinaceous tryptophan-like fluorescent component was the most highly removed one in all the investigated CWs (>28%) and, particularly, in the UVF wetland (66%), whereas humic and fulvic-like components resulted recalcitrant to decomposition. Increases of fluorescence intensities were often observed for fulvic-like substances in CWs operating with saturation of the bed, and these were particularly relevant in the SVF unit. Finally, important correlations (r>0.7) between the tryptophanlike fluorescent component and the water quality parameters COD and BOD5 suggest fluorescence spectroscopy as an useful monitoring tool for water treatment efficiency in CW systems.

“…The efficient elimination of sulfamethoxazole is in accordance with other studies that reported sulfamethoxazole to be degraded under both oxic and anoxic conditions [29]. Accordingly, Jekel et al [30] selected sulfamethoxazole as a process indicator that is well removed in subsurface treatments. The results of this study show that even very short distances and residence times are sufficient for the elimination of sulfamethoxazole.…”

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.

“…The number of pathogens found in the environment can be connected to the number of infected patients but it does not have a linear relation with either the number of patients or wastewater content (WWC) in the receiving waters. Some pharmaceuticals and personal care products (PPCPs) have been proposed as ideal markers because of their relatively constant consumption and ubiquitous occurrence in the environment 3,5 , while not occurring naturally.…”

“…Molecular markers have been widely used as qualitative indicators of faecal pollution of surface and ground waters 3,5 and as indicators of combined sewer overflow in a coastal area 6 . However, molecular markers have rarely been used in a quantitative way, although carbamazepine (CBZ) concentrations were used to estimate leakage of sewage from pipes by comparing concentrations in an aquifer with those in sewage 7 .…”
