“…Hence, oxypurinol was more efficiently attenuated under strongly reducing (sulfidic) conditions. By investigating its degradation during managed aquifer recharge, Hellauer et al [71] found oxypurinol to be persistent during two meters of infiltration under oxic conditions.…”

The process of bank filtration acts as a barrier against many anthropogenic micropollutants, such as pharmaceuticals and industrial products, leading to a substantial improvement of groundwater quality. The performance of this barrier is, however, affected by seasonal influences and subject to significant temporal changes, which have already been described in the literature. Much less is known about spatial differences when considering one field site. In order to investigate this issue, two undisturbed cores from a well-investigated bank filtration field site were sampled and operated in the course of a column study. The ultimate aim was the identification and quantification of heterogeneities with regard to the biodegradation of 14 wastewater derived micropollutants, amongst others acesulfame, gabapentin, metoprolol, oxypurinol, candesartan, and olmesartan. While six of the compounds entirely persisted, eight compounds were prone to degradation. For those compounds that were subject to degradation, degradation rate constants ranged between 0.2 day−1 (gabapentin) and 31 day−1 (valsartan acid). Further, the rate constants consistently diverged between the distinct cores. In case of the gabapentin metabolite gabapentin-lactam, observed removal rate constants differed by a factor of six between the cores. Experimental data were compared to values calculated according to two structure based prediction models.

“…Using aquifers for water storage offers several advantages including avoiding evaporative losses, minimizing the footprint of storage, replenishing depleted aquifers, protecting against land subsidence, and creating hydraulic barriers to protect against saline intrusion (Bekele et al, 2019; Dillon et al, 2018). However, the aquifer storage zone is not inert; therefore, MAR can result in improvements (e.g., inactivation of pathogens and degradation of trace organic chemicals) or deteriorations on the quality of the groundwater (e.g., Hellauer et al, 2018; Pavelic et al, 2007; Prommer et al, 2019; Sharma et al, 2012). Depending on the combination of (i) the injectant composition and (ii) the sediment composition and reactivity, the recharged water can induce a geochemical disequilibrium within the receiving aquifer matrix.…”

Reuse of wastewater through a combination of advanced wastewater treatment (AWT) and managed aquifer recharge (MAR) is an important water management option. As an integral part of any AWT-MAR system, the geochemical compatibility of the recharged water with the targeted aquifer must be assessed to avoid groundwater quality deterioration. Although short-term field experiments may uncover potentially concerning sediment-water disequilibria, an advanced analysis is often required to understand the long-term geochemical impacts of large-scale MAR. Here, we develop and apply a pragmatic approach to upscale and verify the previously derived local-scale geochemical understanding to the spatial and temporal scale required for assessing and managing large-scale and long-term impacts resulting from the recharge of AWT-processed water. We use Australia's largest MAR scheme, in which aerobic, purified water is injected into deep, anaerobic, pyritic aquifers as an illustrative example. In this case, the local-scale understanding was derived from a comprehensive field trial and the interpretation of the data through a trial-scale high-resolution reactive transport model (RTM). Based on (i) the trial-scale RTM, (ii) new data from the early phase of the full-scale MAR, and (iii) downscaling of an existing, regional-scale flow model, we developed an upscaled RTM to assess two critical issues for the large-scale groundwater replenishment of Perth deep aquifers, that is, the sustainability of native pH buffering processes and the dynamics of fluoride release and attenuation. In a final step we illustrate how the upscaled RTM can be applied to assess how changes in the AWT affect long-term groundwater pH changes.

“…In other cases, such as losartan (LOS), transformation products arising from chemical oxidative treatments are deemed to be more toxic than the precursor drug (Carpinteiro et al, 2019). In addition to their stability during oxidative treatments, olmesartan (OLM) and candesartan (CAN) are not removed during soil infiltration of treated wastewaters (Hellauer et al, 2018), which is usually employed to recharge groundwater aquifers. Thus, the presence of sartan residues in tap water has been predicted and confirmed in samples obtained from different European countries, such as Germany and Poland (Giebułtowicz et al, 2016;Stankiewicz et al, 2015).…”

Selective determination of sartan drugs in environmental water samples by mixed-mode solid-phase extraction and liquid chromatography tandem mass spectrometry

et al. 2019

Herein, a method for the simultaneous determination of the currently prescribed sartan drugs (eprosartan, EPR; olmesartan, OLM; losartan, LOS; candesartan, CAN; telmisartan, TEL; irbesartan, IRB; and valsartan, VAL), and the biodegradation product valsartan acid (VALA), in water samples (raw and treated wastewater, river and tap water) was developed. Solid-phase extraction (SPE) and ultra-performance liquid chromatography (UPLC) tandem mass spectrometry (MS/MS) were employed as concentration and determination techniques, respectively. Different sorbents and elution solvents were tested for sample preparation. Under optimized conditions, samples at neutral pH (6 to 8 units) were concentrated using mixed-mode (reversed-phase and anionic exchange) cartridges. Thereafter, the sorbent was washed with 5 mL of a methanol: water (1:1) solution, dried under a nitrogen stream and compounds were eluted with 2 mL of methanol: NH3 (98:2). The accuracy of the method (accounting for SPE efficiency and matrix effects during electrospray ionization) was investigated using solvent-based calibration standards. Global recoveries, obtained for different water matrices (tap, river, treated and raw wastewater), ranged from 82% to 134%, with standard deviations between 2 and 18%. LOQs varied from 2 to 50 ng L -1 . Analysis of un-spiked samples confirmed: (1) the incomplete removal of sartans at sewage treatment plants (STPs), (2) the formation of VALA during municipal water treatment, and (3) the presence of VALA in the processed tap water samples. Additional findings of the current study are the detection of hydroxylated derivatives of the sartan drugs IRB and LOS in wastewater, and the E-Z isomerization of EPR in environmental water samples.
