§ Mr. Barker
To ask the Secretary of State for Environment, Food and Rural Affairs what the cost of removing pesticide and fertiliser contamination from water in water catchment and other areas that affect drinking water supplies was in(a) areas of standard farming procedures and (b) areas where farming is carried out to Soil Association organic standards in the last year for which figures are available. 
§ Mr. Meacher
The Environment Agency, which is responsible for monitoring ground and surface waters for pesticides, does not distinguish between compounds used in conventional and organic farming. Similarly, the costs to water companies of treatment to remove traces of pesticides before water can be put into supply are not quantified and apportioned according to the different farming methods, which may vary within any single water catchment area.
