Contaminant Exposure and Transport from Three Potential Reuse Waters within a Single Watershed

Environmental Science & Technology, Год журнала: 2023, Номер 57(3), С. 1353 - 1365

Global demand for safe and sustainable water supplies necessitates a better understanding of contaminant exposures in potential reuse waters. In this study, we compared load contributions to surface from the discharge three waters (wastewater effluent, urban stormwater, agricultural runoff). Results document substantial varying organic-chemical contribution effluent discharges (e.g., disinfection byproducts [DBP], prescription pharmaceuticals, industrial/household chemicals), stormwater polycyclic aromatic hydrocarbons, pesticides, nonprescription pharmaceuticals), runoff pesticides). Excluding DBPs, episodic storm-event organic concentrations loads were comparable often exceeded those daily wastewater-effluent discharges. We also assessed if irrigation corn resulted measurable effects on rain-induced harvested feedstock. Overall, target-organic 491 g study field during 2019 growing season did not produce dissolved organic-contaminant subsequent events. Out 140 detected organics source irrigation, only imidacloprid estrone had that observable differences between effluent-irrigated nonirrigated fields. Analyses pharmaceuticals per-/polyfluoroalkyl substances at-harvest corn-plant samples two antibiotics, norfloxacin ciprofloxacin, at 36 70 ng/g, respectively, samples; no contaminants noneffluent irrigated samples.

Occurrence, Concentration, and Distribution of 35 PFASs and Their Precursors Retained in 20 Stormwater Biofilters

Current knowledge about the fate and transport behaviors of per- polyfluoroalkyl substances (PFASs) in urban stormwater biofilter facilities is very limited. C5–14,16 perfluoroalkyl carboxylic acids [perfluorinated (PFCAs)], C4,8,10 perfluoroalkanesulfonic (PFSAs), methyl-perfluorooctane sulfonamide acetic acid (MeFOSAA, a PFSA precursor), unknown C6–8 PFCA perfluorooctanesulfonic precursors were frequently found bioretention media forebay sediments at Σ35PFAS concentrations <0.03–19 0.064–16 μg/kg-DW, respectively. Unknown precursor up to ten times higher than corresponding PFCAs, especially forebays biofilters' top layer. No significant trend could be attributed PFAS versus depth filter media, though 2–3 upper layers on average (significant difference between (0–5 cm) deepest (35–50 layer). PFASs had similar spatial concentration distribution each (no clear short- long-chain PFASs). Commercial land use organic matter important factors explaining variations among biofilters sampling depths, Given comparable accumulations deeper superficial possible increased mobility after biotransformation, designing shallow-depth, nonamended sand or maintaining only layer may insufficient for management.

Treatment of polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs) in stormwater using polishing columns with biochar and granular activated carbon

Chemosphere, Год журнала: 2025, Номер 372, С. 144107 - 144107

Опубликована: Янв. 24, 2025

Polycyclic Aromatic Hydrocarbons (PAHs) and Polychlorinated Biphenyls (PCBs) are recalcitrant organic pollutants often detected in stormwater. Various stormwater control measures (SCMs) can remove PAHs PCBs by filtration, adsorption, biodegradation. However, dissolved remain present the treated outflow of SCMs. To provide further treatment, two types biochar (biochar A B), a granular activated carbon (GAC), regenerated GAC (RAC) were tested column study with synthetic containing low concentrations. Results showed that PAH concentrations reduced 98.2-99.8% (range: 62% accumulated at first third due to adsorption onto black material thus providing information for management. difference treatment performances different may be caused molecular structure contaminants. Lifetime calculations indicated had lifetimes >36-51 years, RAC longer than 147 206 respectively, based on predicted precipitation scaled up designs. results carbons efficient adsorbents polishing treatment. With consideration efficiency, sustainability cost, is recommended PCBs.
