“…Simulated groundwater inflows were checked by Hunt et al (1996) using temperature profiles and isotopic mass balances. In other studies, tracers were used to investigate runoff generation processes (Soulsby et al 1998;Jarvie et al 2001), infiltration andEnviron Chem Lett (2009) 7:205-231 223 solute transport mechanisms (Parsons et al 2004) or hydraulic parameters (Maloszewski et al 2006). For an accurate modeling of pesticide mitigation in artificial wetlands, many different processes have to be considered in great spatial and temporal detail.…”

Mitigation of agricultural nonpoint-source pesticide pollution in artificial wetland ecosystems

et al. 2008

International audienceContamination caused by pesticides in agriculture is a source of environmental poor water quality in some of the European Union countries. Without treatment or targeted mitigation, this pollution is diffused in the environment. Pesticides and some metabolites are of increasing concern because of their potential impacts on the environment, wildlife and human health. Within the context of the European Union (EU) water framework directive context to promote low pesticide-input farming and best management practices, the EU LIFE project ArtWET assessed the efficiency of ecological bioengineering methods using different artificial wetland (AW) prototypes throughout Europe. We optimized physical and biological processes to mitigate agricultural nonpoint-source pesticide pollution in artificial wetland ecosystems. Mitigation solutions were implemented at full-scale demonstration and experimental sites. We tested various bioremediation methods at seven experimental sites. These sites involved (1) experimental prototypes, such as vegetated ditches, a forest microcosm and 12 wetland mesocosms, and (2) demonstration prototypes: vegetated ditches, three detention ponds enhanced with technology of constructed wetlands, an outdoor bioreactor and a biomassbed. This set up provides a variety of hydrologic conditions, with some systems permanently flooded and others temporarily flooded. It also allowed to study the processes both in field and controlled conditions. In order to compare the efficiency of the wetlands, mass balances at the inlet and outlet of the artificial wetland will be used, taking into account the partition of the studied compound in water, sediments, plants, and suspended solids. The literature background necessary to harmonize the interdisciplinary work is reviewed here and the theoretical framework regarding pesticide removal mechanisms in artificial wetland is discussed. The development and the implementation of innovative approaches concerning various water quality sampling strategies for pesticide load estimates during flood, specific biological endpoints, innovative bioprocess applied to herbicide and copper mitigation to enhance the pesticide retention time within the artificial wetland, fate and transport using a 2D mixed hybrid finite element model are introduced. These future results will be useful to optimize hydraulic functioning, e.g., pesticide resident time, and biogeochemical conditions, e.g., dissipation, inside the artificial wetlands. Hydraulic retention times are generally too low to allow an optimized adsorption on sediment and organic materials accumulated in artificial wetlands. Absorption by plants is not either effective. The control of the hydraulic design and the use of adsorbing materials can be useful to increase the pesticides residence time and the contact between pesticides and biocatalyzers. Pesticide fluxes can be reduced by 50-80% when hydraulic pathways in artificial wetlands are optimized by increasing ten times the retention time, by recirculation of w...

“…since 2000), the proportion of the publications concerning pesticides' fate in the artificial wetlands increased (Schulz, 2004) and reached 8% of the publications devoted to the artificial wetlands and natural wetlands. The configurations, the localizations and the uses of these kind of zones are numerous and translated into a wide range of vocabulary: vegetated pond system (Revitt et al, 2004), wet ponds or detention pond (Lundberg et al, 1999), constructed vegetative treatment system (Hares and Ward, 2004), created wetland (Kohler et al, 2004), constructed wetlands mesocosm (Hares and Ward, 2004;Sherrard et al, 2004), surface flow constructed wetland (Tanner et al, 2005), constructed freshwater wetland (Cronk and Mitsch, 1994a), vegetated biofilters (Ellis et al, 1994), dry detention pond and wet bioinfiltration pond (Hares and Ward, 1999) and heterogeneous gravel beds constructed wetland (Maloszewski et al, 2006).

Contamination caused by pesticides in agriculture is a source of poor environmental water quality in some of the European Union countries. Without treatment or targeted mitigation, this pollution is diffused in the environment. Pesticides and their metabolites are of increasing concern because of their potential impacts on the environment, wildlife and human health. Within the context of the European Union (EU) Water Framework Directive and to promote low-pesticide-input farming and best management practices, the EU LIFE project ArtWET assessed the efficiency of ecological bioengineering methods using different artificial wetland (AW) prototypes throughout Europe. We optimized physical and biological processes to mitigate agricultural nonpoint-source pesticide pollution in AW ecosystems. Mitigation solutions were implemented at full-scale demonstration and experimental sites. We tested various bioremediation methods at seven experimental sites. These sites involved (1) experimental prototypes, such as vegetated ditches, a forest microcosm and 12 wetland mesocosms, and (2) demonstration prototypes, such as vegetated ditches, three detention ponds enhanced with technology of constructed wetlands, an outdoor bioreactor and a biomassbed. This set-up provides a variety of hydrologic conditions, with some systems permanently flooded and others temporarily flooded. It also allowed to study processes both in field and controlled conditions. In order to compare the efficiency of the wetlands, mass balances at the inlet and outlet of the AW will be used, taking into account the partitioning of the studied compound in water, sediments, plants and suspended solids. The literature background necessary to harmonize the interdisciplinary work is reviewed here and the theoretical framework regarding pesticide removal mechanisms in AWs is discussed. The development and the implementation of innovative approaches concerning various water quality sampling strategies for pesticide load estimates during flood, specific biological endpoints, innovative bioprocesses applied to herbicide and copper mitigation to enhance the pesticide retention time within the AW, modelling the transport and the fate of pesticides using a 2D mixed hybrid finite element model are introduced. These future results will be useful to optimize hydraulic functioning, e.g. pesticide resident time, and biogeochemical conditions, e.g. dissipation, inside the AWs. Hydraulic retention times are generally too low to allow an optimized adsorption on sediment and organic materials accumulated in AWs. Absorption by plants is also not effective (VanBeinum et al., 2006). The control of the hydraulic design and the use of adsorbing materials can be useful to increase the pesticide's residence time and the contact between pesticides and biocatalyzers. Pesticide fluxes can be reduced by 50-80% when hydraulic pathways in AWs are optimized by increasing ten times the retention time, by recirculation of water, and by deceleration of the flow. Thus, using a bioremediat...
