§ 64. Mr. Arthur Jonesasked the Secretary of State for the Environment what studies and research are being undertaken to ensure adequate standards for the effluent which can be discharged into rivers from which water undertakings are drawing supplies.
§ Mr. Peter WalkerRiver authorities are responsible for fixing appropriate standards and some are undertaking studies in that context: my Steering Committee on Water Quality is responsible for promoting general studies. Most of the research on the degree to which effluents need to be purified to prevent interference with the uses to which a river may be put is being undertaken by the Water Pollution Research Laboratory of my Department.
