Recent European environmental legislation (the Water Framework Directive, the Environmental Liability Directive, and the REACH Regulation) should provide better protection of terrestrial water bodies but their focus is on the more conspicuous pollutants, as opposed to the large number of xenobiotic micro-pollutants that are increasingly being detected in the urban water cycle. The development of Drinking Water Safety Plans (DWSPs), as promoted by the World Health Organization, utilises a proactive risk assessment--risk management approach that necessarily should include micro-pollutants, although currently in the UK micro-pollutants have largely been ignored. The generic assessment of the risks posed by micro-pollutants is proposed and will require a consensus on analytical screening methods, sampling points and frequencies, and a method for prioritising concern, and would enable DWSPs to take fuller account of the risks posed.
