§ Mr. RedmondTo ask the Secretary of State for the Environment if he will investigate the extent to which water in the aquifers of the Doncaster area geological syncline could be used in greater volumes, either in the public water supply or other purposes; what is the current cost of obtaining potable water from this source; what capital and revenue cost would be incurred in using sufficient water for these uses so as to stabilise the height of the local water table; and if he will make a statement. [39035]
§ Mr. ClappisonThe National Rivers Authority has a duty to conserve and secure the proper use of water resources in England and Wales. I understand that the Sherwood sandstone aquifer in the Doncaster area is already fully utilised for public water supply. It is possible that some groundwater could be made available from the carboniferous stratum, but the quantities are expected to be small and the water quality poor. The cost of obtaining a potable water supply or stabilising the local water table have not been investigated.
