“…There may be many other native species that are imperiled but remain understudied and have not yet received the attention or momentum necessary to begin the listing process. We also acknowledge that effluent may contain contaminants, in particular endocrine disruptors, antibiotics, and other pharmaceuticals, that escape treatment and result in concentrations that exceed safety thresholds (Ankley et al., 2007; Kamanmalek et al., 2022; Rice & Westerhoff, 2017). There is scant understanding of the prevalence, duration, and effects of these pollutants on at‐risk species which create trade‐offs on the quantity and quality of flow in effluent in streams.…”

A changing climate and often unregulated water extractions have exposed over 2 billion people to water stress worldwide. While water managers have explored a portfolio of options to reduce this stress, supply augmentation through reuse of treated municipal wastewater is becoming increasingly attractive. Wastewater treatment plants protect water quality and prevent sewage from contaminating waterways. Increasingly, this resource is utilized for numerous human (e.g., irrigation, drinking water, groundwater recharge) and conservation (e.g., stream and river recharge) needs in water stressed regions. To understand the role treated municipal wastewater plays in impacting conservation objectives we identified the intersection of wastewater treatment plant locations and occurrences of threatened and endangered (T&E) species in California and compared the permitted contribution of effluent to baseflow quantities of the receiving waterbody to assess the degree to which changes in effluent could affect instream waterbodies. We found a positive correlation between the presence of treatment plants and T&E species in California watersheds—a quarter of species have 100% of their range in watersheds with at least one treatment plant. This correlation is greatest for species associated with terraces and riparian habitat, followed by aquatic habitat and aquatic emergent vegetation. One‐third of watersheds in our analysis can receive most of their cumulative watershed baseflow from effluent and are characterized by dense urbanization or agriculture. Our analysis demonstrates that the fates of T&E species and effluent are interconnected in ways important for water policy, suggesting that species conservation goals should be considered when making decisions about effluent reuse.

Increasing contamination of water bodies with antibiotics has necessitated the development of novel mitigation methods. Many studies have applied adsorption and photocatalytic processes using different nanoparticles, metal‐organic frameworks, etc., as sorbents and photocatalysts for antibiotics removal. Among these materials, the development of molecular imprinted polymers (MIPs) is desirable owing to their low cost, structural predictability, detection at deficient concentrations, and versatile applicability. These attributes further encouraged researchers to fabricate hybrid MIP‐based materials to abate antibiotic contamination in wastewater. This review summarizes recent studies that deal with conventional and hybrid MIPs such as MIPs‐hybrid carbon nanomaterials, magnetic nanomaterials, advanced MIP‐based sensors, and photocatalytic materials MIPs for synergic adsorption/separation of antibiotic residuals from wastewater. Economic perspectives of the emerging hybrid materials are also discussed. Some limitations, research gaps, and future potentials for further advancement and efficient remediation results are outlined.

“…A recent study of AR in US streams affected by WWTP discharges under varying instream flow conditions found that under low instream flow conditions, 26% of the streams did not meet the AR safety threshold for ciprofloxacin (CIP) and erythromycin (ERY) [ 7 ]. It is important to note that 5% of the dose of ERY is excreted in the active form in the urine and that ERY is recalcitrant to different treatments in WWTPs, with wastewater from WWTPs, pharmaceutical facilities, and hospitals being the main contributors to the spread of ERY [ 8 ].…”

Water recycling and reuse are cornerstones of water management, which can be compromised by the presence of pollutants. Among these, pharmaceuticals can overcome standard water treatments and require sophisticated approaches to remove them. Sorption is an economically viable alternative limited by the need for sorbents with a sorption coefficient (Kd) higher than 500 L/kg. The cross-linking of dextrin (Dx) with divinyl sulfone (DVS) in the presence of 1 mmol or 5 mmol of ibuprofen (IBU) yields the insoluble polymers pDx1 and pDx5 with improved affinity for IBU and high selectivity towards erythromycin (ERY) and ERY Kd higher than 4 × 103 L/kg, when tested against a cocktail of six drugs. Characterization of the polymers shows that both pDx1 and pDx5 have similar properties, fast sorption kinetics, and ERY Kd of 13.3 × 103 for pDx1 and 6.4 × 103 for pDx5, representing 26.6 and 12.0 times the 500 L/kg threshold. The fact that new affinities and improvements in Kd can be achieved by cross-linking Dx in the presence of other molecules that promote pre-organization expands the applications of DVS cross-linked polysaccharides as sustainable, scalable, and environmentally friendly sorbents with a potential application in wastewater treatment plants (WTPs).
