§ Mr. Onslowasked the Secretary of State for the Environment what is the estimated cost, in each regional water authority area in England and Wales, of implementation of Part II of the Control of Pollution Act.
§ Mr. Denis HowellNo such estimates can be made, since costs would depend on the standards set by the water authorities, but any major overall improvements in the quality of rivers and tidal waters would involve very substantial capital expenditure by both water authorities and industry.
