“…Other research has shown that a riparian buffer zone can lead to pollution swapping. McKergow et al, (2003) and Stevens and Quinton (2009) showed post riparian buffer zone establishment there can be a substitution effect in the dominant P form from total phosphorus to filterable reactive phosphorus thereby limiting the effectiveness of riparian buffers for reducing P exports.…”

In the European Union, mitigation measures to abate diffuse pollution from agricultural land are implemented under the direction of the EU Nitrates and Water Framework Directives. As these measures are implemented in national policies, a review process will look at the efficacy of the measures with a view to recommending further measures as necessary and following scientific and stakeholder consultation. Riparian buffer zones, beyond those zones used as mandatory set back distances for fertiliser and organic manure spreading, have been used as filters in some countries to attenuate nutrient rich runoff and may be proposed as supplementary measures elsewhere. Notwithstanding the ongoing research on the physio-chemical efficiency of riparian buffer zones, this study examined the willingness of farmers to adopt such features on agricultural land. The sample size was 247 farmers in 12 catchments (approximately 4-12km 2 ) in the Republic of Ireland. The survey was based on a proposal to install a 10 metre deep riparian buffer zone on a five year scheme and the analysis was based on principal components analysis, contingent valuation methodology and a Generalized Tobit Interval model. Results from this analysis indicated that famers' willingness to supply a riparian buffer zone depended on a mix of economic, attitudinal and farm structural factors. A total of 53% of the sample indicated a negative preference for provision. Principle constraints to adoption include interference with production, nuisance effects and loss of production in small field systems. Of those willing to engage with supply, the mean willingness to accept based cost of provision for a 10 metre riparian buffer zone was estimated to be €1513 ha -1 per annum equivalent to €1.51 per linear metre of riparian area.

“…heavy-metals, BTEX and TCE) (Kober et al, 2002). Besides the incapability of such barriers to treating multicontaminants, research has been going on to deal with the problem of pollutant mixing, which is the headless generation of new potentially hazardous contaminants while removing other contaminants (Stevens and Quinton, 2009;Healy et al, 2012). However, in the path of increased global environmental concern and use of sustainability approach for remediation, pollutant swapping has become a major concern.…”

It is an indisputable fact that any environmental clean-up technology generating certain kind of effective result would be easily supported. One of them includes Permeable reactive bio-barrier which is an innovative technology started from 90's to treat a variety of contaminants along the natural gradient flow of groundwater through immobilization or transformation of pollutants into less toxic and harmful form. Despite of any broad acknowledgement, there are lesser known knowledge about use of microorganisms in permeable reactive barriers, mingling of microorganisms with other reactive media and their effect on each other's reactivity. The current review deals with an overview of the types of reactive media used in Permeable Reactive Barriers (PRBs) as well as different bio-barriers (PRBBs) utilized for the treatment of various contaminants, long-term performance of permeable reactive barrier and combination of microorganism and reactive media to look forward for their symbiotic relationship in permeable reactive barrier for environmental remediation.

“…water companies) (Whitehead et al, 2013). Modelling can highlight any potential problems such as changes in nutrient form, known as pollution swapping (Stephens and Quinton, 2009). In essence, the model shows how catchment management decisions impact nutrient concentrations and fluxes at the scale of assessment.…”

Abstract.A model for simulating runoff pathways and water quality fluxes has been developed using the minimum information requirement (MIR) approach. The model, the Catchment Runoff Attenuation Flux Tool (CRAFT), is applicable to mesoscale catchments and focusses primarily on hydrological pathways that mobilise nutrients. Hence CRAFT can be used to investigate the impact of flow pathway management intervention strategies designed to reduce the loads of nutrients into receiving watercourses. The model can help policy makers meet water quality targets and consider methods to obtain "good" ecological status.A case study of the 414 km 2 Frome catchment, Dorset, UK, has been described here as an application of CRAFT in order to highlight the above issues at the mesoscale. The model was primarily calibrated on 10-year records of weekly data to reproduce the observed flows and nutrient (nitrate nitrogen -N; phosphorus -P) concentrations. Data from 2 years with sub-daily monitoring at the same site were also analysed. These data highlighted some additional signals in the nutrient flux, particularly of soluble reactive phosphorus, which were not observable in the weekly data. This analysis has prompted the choice of using a daily time step as the minimum information requirement to simulate the processes observed at the mesoscale, including the impact of uncertainty. A management intervention scenario was also run to demonstrate how the model can support catchment managers investigating how reducing the concentrations of N and P in the various flow pathways. This mesoscale modelling tool can help policy makers consider a range of strategies to meet the European Union (EU) water quality targets for this type of catchment.
