Water UK metaldehyde briefing paper
The water industry, along with farmers and producers, has demonstrated a successful voluntary approach to reducing the concentrations of metaldehyde in rivers, reservoirs and drinking water over the past few years. However, 2012 was an exceptional year, with the combination of a dry start followed by a very wet summer and autumn. This increased both the presence of slugs and snails and also the tendency for rapid run-off of water from treated land.
The resulting increases in metaldehyde in drinking water resulted in breaches of UK and EU standards. To ensure that the reductions seen in previous years are sustainable, water companies are assessing where high-risk areas or hotspots exist and, working with stakeholders, considering a range of extra options in these areas to reduce the risk from metaldehyde...
