“…The results compared well with the findings of Barnes et al (2008) and Focazio et al (2008) for the USA in terms of frequency for selected compounds. In a reconnaissance survey for streams Kolpin et al (2002) found the detection frequency for the same analytical suite as used by Barnes et al (2008) for groundwater to be greater by a factor of 2.4.…”

The more frequent occurrence of EOCs in surface waters reflects the direct input from waste water sources, short residence times and the limited dilution and attenuation capacity of surface water compared to groundwater .…”

Emerging organic contaminants (EOCs) detected in groundwater may have adverse effects on human health and aquatic ecosystems. This paper reviews the existing occurrence data in groundwater for a range of EOCs including pharmaceutical, personal care, 'life-style' and selected industrial compounds. The main sources and pathways for organic EOCs in groundwater are reviewed, with occurrence data for EOCs in groundwater included from both targeted studies and broad reconnaissance surveys. Nanogram-microgram per litre concentrations are present in groundwater for a large range of EOCs as well as metabolites and transformation products and under certain conditions may pose a threat to freshwater bodies for decades due to relatively long groundwater residence times. In the coming decades, more of these EOCs are likely to have drinking water standards, environmental quality standards and/or groundwater threshold values defined, and therefore a better understanding of the spatial and temporal variation remains a priority.Keywords: emerging contaminants; review; groundwater; pharmaceuticals; occurrence Capsule: A large range of emerging organic contaminants are now being detected in groundwater as a result of recent and historical anthropogenic activities. IntroductionA diverse array of synthetic organic compounds are used by society in vast quantities for a range of purposes including the production and preservation of food, industrial manufacturing processes, as well as for human and animal healthcare. In the last few decades there has been a growing interest in the occurrence of these, so called, 'micro-organic contaminants' in the terrestrial and aquatic environment, their environmental fate and their potential toxicity (Stan and Linkerhagner, 1992;Stan et al., 1994;Halling-Sørensen et al., 1998;Daughton and Ternes, 1999;Schwarzenbach et al., 2006;Kümmerer, 2009). The contamination of groundwater resources by micro-organics is a growing concern and relatively poorly understood compared to other freshwater resources. Groundwater provides the most reliable perennial source of freshwater on Earth. It maintains flows and levels in rivers and lakes, is essential for the health of groundwater-dependant ecosystems, and in many parts of the world is the most important source of drinking water.Of particular concern are 'emerging organic contaminants' (EOCs). This term is used to cover not only newly developed compounds but also compounds newly discovered in the environment -often due to analytical developments (Lindsey et al., 2001;Petrovic and Barceló, 2006;Richardson and Ternes, 2011) and compounds that have only recently been categorised as contaminants. EOCs include a wide array of different compounds (as well as metabolites and transformation products-collectively referred to here as degradates)including; pharmaceuticals and personal care products (PPCPs), pesticides, veterinary products, industrial compounds/by-products, food additives as well as engineered nanomaterials. Because of the vast array of possible comp...

“…Various antibiotics have been frequently detected in groundwater Batt et al, 2006a), drinking water (Focazio et al, 2008), surface water (Hirsch et al, 1999;Yang et al, 2011), sediment (Zhou et al, 2011) and agricultual lands (Hu et al, 2010;Karci and Balcioglu, 2009). Wide occurrence of antibiotics in the environment could affect aquatic and terrestrial organisms (Costanzo et al, 2005;Kotzerke et al, 2008;Liu et al, 2009), alter microbial activity and community composition (Underwood et al, 2011), and lead to prevalence of bacterial resistance to antibiotics (LaPara et al, 2011;Su et al, 2012;Tao et al, 2010).…”

“…Due to the improper and untreated disposal of sulfonamides in feed, sulfonamides and their metabolites are widespread in the environments and have frequently resulted in the contamination of water or soil (Halling et al 1998;Fent et al 2006;Ye et al 2007;Barnes et al 2008;Focazio et al 2008). Sulfonamides are now widely recognized as environmental contaminants (Sukul and Spiteller 2006).…”

“…Biodegradation of sulfonamides present in wastewater treatment plants (WWTPs), surface water, manure and soils was summarized by Jesús García-Galán et al (2008). Sulfonamides appeares to resist natural biodegradation rather strongly, which is reflected in the high frequency of their detection in streams and rivers (Kim et al 2007;Vieno et al 2007;Barnes et al 2008;Focazio et al 2008). Kuhn and Suflita (1989) reported the anaerobic biodegradation of para-toluenesulfonamide and benzenesulfonamide in aquifer slurries from a sulphate-reducing and methanogenic site.…”

With the intensive application of sulfonamides in aquaculture and animal husbandry and the increase of sulfonamides discharged into the environments, there is an increasing need to find a way to remediate sulfonamidecontaminated environments. Two bacterial strains capable of degrading sulfonamides, HS21 and HS51, were isolated from marine environments. HS21 and HS51 were identified as members of Escherichia sp. and Acinetobacter sp., respectively, based on 16S rRNA gene sequencing. Degradation of each sulfonamide by Escherichia sp. HS21 and Acinetobacter sp. HS51 was characterized using capillary electrophoresis. About 66 or 72% of sulfapyridine and 45 or 67% of sulfathiazole contained in the media was degraded by Escherichia sp. HS21 or Acinetobacter sp. HS51, respectively, after incubation for 2 days. The supernatant from culture of Escherichia sp. HS21 or Acinetobacter sp. HS51 grown in sulfapyridine or sulfathiazole contained media had much attenuated cytotoxicity against HeLa cells. These results suggest that Escherichia sp. HS21 and Acinetobacter sp. HS51 are new bacterial resources for biodegrading sulfonamides and indicate the potential of isolated strains for the bioremediation of sulfonamide-polluted environments.
