HC Deb 22 July 1958 vol 592 c17W
24. Mrs. Castle

asked the Minister of Housing and Local Government and Minister for Welsh Affairs how many local authorities are making arrangements to test their water supply regularly for radioactivity.

Mr. Bevins

Local authorities and other statutory water undertakers do not need my right hon. Friend's permission to test their water for radioactivity. To my knowledge, however, at least eight of them have made, or contemplate making, such arrangements.
