Abstract

(RS)-MCPP is one of a group of chlorophenoxyalkanoic acids in widespread use as herbicides for broad-leaved weeds in cereal crops, grasslands and lawns (Harrison et al., 2003). It has been detected in municipal wastewater, surface water, landfill leachate and groundwater (Fletcher et al., 2004) and falls within List 1 of the Groundwater Regulation 1998 (Statutory Instrument 1998 No. 2746) needs to be treated before discharge, with measurable quantities of (RS)-MCPP being considered as a primary indicator of pollution. Alternative terminal electron acceptors, such as sulphate may be present at significant concentrations in the sources where (RS)-MCPP is frequently detected such as municipal wastewater, surface water, landfill leachate and groundwater (Bucheli et al., 1998; Petrovic & Larsson-Kovach, 1996; Zipper, et al., 1998; Fletcher et al., 2004). These will have a bearing on the redox conditions and affect the composition of the microbial populations in any reactor system treating these sources, both of which are likely to have an impact on the fate of (RS)-MCPP during treatment.
