“…From the Ganges River Basin in India to the surface water in Milan, contaminants such as pharmaceuticals and personal care products have been detected. [1][2][3][4][5][6][7][8][9] These contaminants are difficult to remove and can cause harm not only to humans but to wildlife and local ecosystems as well. Pharmaceuticals, personal care products, persistent organic pollutants, methanesulfonic acids, artificial sweeteners, transformation products, and engineered nanomaterials have all been identified as current contaminants of emerging concern (CECs).…”

Increasing human activity, including commercial and noncommercial use of pharmaceuticals, personal care products, and agricultural products, has introduced new contaminants that can be challenging to remove with currently available technologies. Pharmaceuticals, in particular, can be especially challenging to remove from the water supply and can pose great harm to people and local ecosystems. Their highly stable nature makes their degradation with conventional water treatment techniques difficult, and studies have shown that even advanced treatment of water is unable to remove some compounds. As such, decontamination of water from pharmaceuticals requires the development of advanced technologies capable of being used in indirect and direct potable water reuse. In this review, we discuss pharmaceutical removal in indirect potable water treatment and how recent advancements in adsorption and photocatalysis technologies can be used for the decontamination of pharmaceutical-based emerging contaminants. For instance, new materials that incorporate graphene-based nanomaterials have been developed and shown to have increased adsorptive capabilities toward pharmaceuticals when compared with unmodified graphene. In addition, adsorbents have been incorporated in membrane technologies, and photocatalysts have been combined with magnetic material and coated on optical fibers improving their usability in water treatment. Advancements in photocatalytic material research have enabled the development of highly effective materials capable of degradation of a variety of pharmaceutical compounds and the development of visible-light photocatalysts. To understand how adsorbents and photocatalysts can be utilized in water treatment, we address the benefits and limitations associated with these technologies and their potential applicability in indirect potable water reuse plants.

“…NP belongs to category 1 (clear evidence of endocrine disrupting effects in an intact organism) of the endocrine disrupter priority list (Wang et al, 2016). The occurrence of NP has been reported in different environmental compartments worldwide, as well as within humans and other biota (Fairbairn et al, 2016;Staniszewska et al, 2016;Wang et al, 2016;Diao et al, 2017;Lin et al, 2017;Peng et al, 2017). According to a study conducted in the Zumbro River watershed of United States, the concentration of NP was up to 10 4 ng/L (Fairbairn et al, 2016).…”

“…In the dry season, runoff from the Minjiang River is small and the density of NH 3 -N is high -in contrast to the rainy season [35]. Also, in main stream of the Zhujiang River, higher total contaminant concentrations were observed in samples collected in the dry season compared to those in the wet season [36]. Anna [37] seemingly found the reason why few flood events are responsible for nearly 60% of the total annual N load: because when most of the basin is covered by vegetation, soils are generally wet, and runoff generation is mainly due to "saturation excess" in wet season.…”
