PROBLEM AND RESEARCH OBJECTIVES Many substances used in domestic households are persistent and pass through conventional wastewater treatment. Among these, chemicals of emerging concern (CECs), including endocrine disrupting compounds (EDCs), are of particular interest. In a 2002 nationwide survey, the USGS measured some of the highest in-stream concentrations of EDCs in the effluentdependent lower Santa Cruz River (SCR) near Tucson. Targeted testing by the City of Tucson during 2009 and 2010 under their Microconstituent Sentinel Program detected the compounds perfluorooctane sulfonate (PFOS), carbamazepine, and sulfamethoxazole in three groundwater production wells located along the lower SCR (15-20 mi downstream from wastewater effluent outfalls), suggesting that extracted ground water may include a component of effluent origin. Clearly, concern is warranted regarding the presence and fate of CECs in the Lower SCR watershed.

Red dots: major water reclamation facilities; black stars: sampling sites in the 2011 campaign (river water and groundwater wells); green dots: river water sampling sites in the 2012-13 campaigns. Relative distances for all sampling points are reported in Tables B-4 and B-5. In February 2014, the Roger Road Wastewater Treatment Plant (RRWTP) was replaced by the Agua Nueva Water Reclamation Facility (WRF); and the Ina Road Water Reclamation Facility (IRWRF) was similarly upgraded and renamed Tres Rios WRF. Except during periods of widespread rain, the SCR only flows along the northwest direction from the RRWTP, and the tributaries seen in the figure are completely dry.

The fate of dissolved organic matter (DOM) during subsurface wetland treatment of wastewater effl... more The fate of dissolved organic matter (DOM) during subsurface wetland treatment of wastewater effluent in a hot, semi-arid environment was examined. The study objectives were to (1) discern changes in the character of dissolved organics as consequence of wetland treatment (2) establish the nature of wetland-derived organic matter, and (3) investigate the impact of wetland treatment on the formation potential of trihalomethanes (THMs). Subsurface wetland treatment produced little change in DOM polarity (hydrophobic-hydrophilic) distribution. Biodegradation of labile effluent organic matter (EfOM) and internal loading of wetland-derived natural organic matter (NOM) together produced only minor changes in the distribution of carbon moieties in hydrophobic acid (HPO-A) and transphilic acid (TPI-A) isolates of wetland effluent. Aliphatic carbon decreased as a percentage of total carbon during wetland treatment. The ratio of atomic C:N in wetland-derived NOM suggests that its character is determined by microbial activity. Formation of THMs upon chlorination of HPO-A and TPI-A isolates increased as a consequence of wetland treatment. Wetland-derived NOM was more reactive in forming THMs and less biodegradable than EfOM. For both HPO-A and TPI-A fractions, relationships between biodegradability and THM formation potential were similar among EfOM and NOM isolates; the less biodegradable isolates exhibited greater THM formation potential.

NOM is of concern because it serves as an organic precursor for production of halogenated disinfection byproducts (DBPs) during drinking water treatment. This paper reviews previous research on SAT with wastewater effluent, provides an overview of results from riverbank filtration studies in Europe and in the United States, and finally, provides some thoughts regarding the application of SAT as part of a treatment process for Colorado River water. Results from a multi-year field and laboratory-based investigation performed by researchers involved with the project "An Investigation of Soil-Aquifer Treatment for Sustainable Water Reuse" indicate that SAT is a sustainable process for significantly reducing the concentration of dissolved organic carbon (DOC) in wastewater effluent. Intensive monitoring at ...

We examined the fate of organics during wetland treatment of secondary effluent and groundwater (... more We examined the fate of organics during wetland treatment of secondary effluent and groundwater (control) flows in parallel, research-scale, subsurface-flow (SSF) wetland raceways at the Constructed Ecosystem Research Facility (CERF) located in Tucson, Arizona. The CERF facility enabled us to distinguish experimentally among effects on effluent quality due to season-dependent processes of evapotranspiration (ET) and wetlands-derived production of organics. Organics of wastewater and wetlands origin were compared in terms of their contributions to dissolved organic carbon (DOC) in wetland effluent. Elevated temperatures and associated biochemical activities increased DOC levels in wetland effluents during summer. In other words, DOC removal efficiency was negatively correlated to temperature. The contributions of ET and wetland-derived organics to elevation of DOC in wetland effluents during summer were roughly comparable. The elevation of organic carbon concentration during wetland ...

Fractions were isolated using XAD resin adsorption chromatography from samples obtained along the vadose zone flowpath at a full-scale basin recharge facility in Tucson, Arizona. Changes in isolate character during SAT were established via biodegradability (batch test), specific ultraviolet light absorbance (SUVA), trihalomethane formation potential (THMFP), and Ames mutagenicity assays. The dissolved organic carbon (DOC) concentration decreased by >90% during SAT. A significant fraction (up to 20%) of isolated post-SAT HPO-A was biodegradable. The (apparent) refractory nature of DOM that survives SAT may be a consequence of low DOC concentration in groundwater as well as the nature of the compounds themselves. Specific THMFP (microg THM per mg DOC) of HPO-A and TPI-A varie...
