“…Focazio et al, 2008), and are therefore an important source and pathway of EOC pollution of groundwater bodies as a result of both natural (Lapworth et al, 2009) and engineered GW-SW exchange processes (Drewes, 2009). 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 .…”

“…It is a particularly useful management tool in semi-arid regions where water resources are scarce (Gale and Dillon, 2005;Drewes, 2009;Lev et al, 2011). It is used to replenish aquifers, use them as natural temporary storage systems, and in some cases manage river flow (Bouwer, 2002;Daher et al, 2011).…”

“…More arid environments have been shown to be particularly susceptible to groundwater contamination by EOCs due to intentional and unintentional recharge of waste water sources (Drewes et al, 2003;Drewes, 2009;Gasser et al, 2010;Cabeza et al, 2011). The ratio between natural recharge and artificial recharge is such that there is less potential for dilution and natural attenuation.…”

“…As a result the impact on groundwater quality from these activities is greater and perhaps less sustainable over long time periods. This is a very real challenge as artificial recharge remains an important water resource management option in arid, water scarce areas of the world (Drewes, 2009;Fram and Belitz, 2011).…”

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...

“…Surface waters contain higher concentrations, and a larger range of ECs than groundwaters reflecting the direct input from wastewater sources, short residence times and the limited dilution capacity of surface water compared to groundwater [101][102]. ECs have been used to great effect to trace SW-GW exchange processes and as markers of wastewater sources [59,[103][104][105]. SW-GW exchange is particularly important in aquifers below and adjacent to water courses, for example in shallow alluvial aquifers, which are important sources of drinking water in many parts of the world.…”

Emerging Organic Contaminants in Groundwater

Emerging organic contaminants (ECs) are compounds now being found in groundwater from agricultural, urban sources that were previously not detectable, or thought to be significant. ECs include pesticides and degradates, pharmaceuticals, industrial compounds, personal care products, fragrances, water treatment byproducts, flame retardants and surfactants, as well as 'life-style' compounds such as caffeine and nicotine. ECs may have adverse effects on aquatic ecosystems and human health.Frequently detected ECs include the anti-epileptic drug carbamazepine, the antibiotic sulfamethoxazole, the anti-inflammatories ibuprofen and diclofenac, and caffeine, as well as pesticide degradates. This means there will be challenges in the future in order to address these ECs and to minimise their impact on drinking water and ecosystems. In the coming decades, more ECs are likely to have environmental standards defined, and therefore a better understanding of environmental behaviour remains a priority.

Heat and mass transport during a groundwater replenishment trial in a highly heterogeneous aquifer

Changes in subsurface temperature distribution resulting from the injection of fluids into aquifers may impact physiochemical and microbial processes as well as basin resource management strategies. We have completed a 2 year field trial in a hydrogeologically and geochemically heterogeneous aquifer below Perth, Western Australia in which highly treated wastewater was injected for large-scale groundwater replenishment. During the trial, chloride and temperature data were collected from conventional monitoring wells and by time-lapse temperature logging. We used a joint inversion of these solute tracer and temperature data to parameterize a numerical flow and multispecies transport model and to analyze the solute and heat propagation characteristics that prevailed during the trial. The simulation results illustrate that while solute transport is largely confined to the most permeable lithological units, heat transport was also affected by heat exchange with lithological units that have a much lower hydraulic conductivity. Heat transfer by heat conduction was found to significantly influence the complex temporal and spatial temperature distribution, especially with growing radial distance and in aquifer sequences with a heterogeneous hydraulic conductivity distribution. We attempted to estimate spatially varying thermal transport parameters during the data inversion to illustrate the anticipated correlations of these parameters with lithological heterogeneities, but estimates could not be uniquely determined on the basis of the collected data.
