§ Miss Maynardasked the Secretary of State for the Environment if he will indicate the geographical area of the five water supplies in Lincolnshire in respect of which action has had to be taken to reduce the concentration of nitrates and if he will make a statement on the progress made to date by the Anglian water authority to comply with the relevant European Community directives.
§ Mr. John PattenThe geographical areas are as follows
two areas in and around Sleaford;the Potterhanworth supply area;the Waneham Bridge-Saltersford supply area;the Horbling supply area in South Kesteven.Action has been taken by the Anglian water authority to reduce the nitrates content of water supplies to these areas below 80mg per litre on a three-monthly average. This is considered by our medical advisers to be an acceptable level. A small supply in Norfolk was taken out of use recently because the nitrate level was unacceptable.
§ Miss Maynardasked the Secretary of State for the Environment if he will furnish details of the geographical areas covered by those water supplies in respect of which applications for derogations from the maximum admissible concentrations have been made by the Anglian water authority and the Yorkshire water authority; and if he will indicate which of these applications for derogations were refused.
§ Mr. John PattenDetails of the relevant areas are attached. No applications have been refused but a number have been modified or withdrawn as a result of discussions with the Department. Applications have also been approved subject to conditions. Programmes of improvement have accompanied many of the applications including all those relating to the microbiological parameters.
