Evaluation of emerging contaminants of concern at the South District Wastewater Treatment Plant based on seasonal sampling events, Miami-Dade County, Florida, 2004

Sources of nutrients impacting surface waters in Florida: A review

“…The most commonly detected chemicals are lipid-regulating drugs, analgesics, plasticizers, anionic surfactant metabolites, herbicides, a nicotine metabolite, caffeine and its metabolites, animal steroids, antibiotics, industrial dyes, fecal steroids, plant steroids, antiepileptics and mood stabilizers, polycyclic musks, disinfection byproducts, antiasthmatics, fire retardants, wood binders, an insect repellent and chelating agents (Kolpin et al, 2002;Drewes et al, 2003Drewes et al, , 2008Snyder et al, 2003Snyder et al, , 2004Masters et al, 2004; Leenhouts et al, 1998;Vengosh et al, 1994;Bassett et al, 1995;Komor, 1997;Seiler, 2005 Nitrogen & Oxygen Sufficient contrast between the isotopic ratio of fertilizer-driven U and natural U may be required Zielinski et al, 2000;Osmund and Cowart, 1976;Osmund, 1992 Soliman et al, 2007;Lietz and Meyer, 2006;Singh, 2006;Helgeson and McNeal, 2009;Dickenson et al, 2009;USEPA, 2010). A large number of these trace compounds were found in Florida wastewater treatment plant effluents and receiving waterbodies.…”

Occurrence and potential transport of selected pharmaceuticals and other organic wastewater compounds from wastewater-treatment plant influent and effluent to groundwater and canal systems in Miami-Dade County, Florida

“…There were also four occasions when PR values could not be calculated for codeine. In a similar treatment study using the same analytical method, Lietz and Meyer (2006) reported higher concentrations of codeine, diltiazem, and diphenhydramine in effluent samples compared to influent samples, and attributed the higher concentrations in effluent samples to solubility changes caused by matrix conditions and (or) issues with matrix interferences using the LC/MS method. Percent reduction values for ibuprofen were high (greater than 76.9 percent) during treatment for all but one sample occasion (NDWWTP, dry season).…”

“…Sando and others (2005) measured 50-60 pharmaceuticals and other organic wastewater compounds in treated wastewater effluent in South Dakota. Lietz and Meyer (2006) reported that 30-35 pharmaceuticals and other organic wastewater compounds were present in treated effluent from Miami-Dade County, Florida. These compounds also have been detected in surface waters that receive wastewater discharges and some of these compounds could be sufficiently mobile to be transported to the groundwater.…”

“…All equipment was decontaminated and the laboratory area was cleaned and lined with aluminum foil prior to processing, following previous methods (Lietz and Meyer, 2006). The initial step in the decontamination procedure involved cleaning the equipment with a dilute phosphate-free detergent.…”

Microcontaminant Sorption and Biodegradation in Wastewater Modeled as a Two-Phase System

“…As the research on the origination of these microcontaminants has progressed, it has become more apparent that wastewater treatment plants play a critical role (Lietz and Meyer 2004, Glassmeyer et al 2005, Vanderford and Snyder 2006, Yu et al 2006. These facilities are located at the nexus connecting the anthropogenic with the ecological and, as such, have become a focal point for environmental research, especially in regards to the fate, transport, and occurrence of emerging contaminants.…”
