During 1960, of 257 samples of the water pumped to su pply 254 were entirely satisfactory. 160 samples of the water prior to chlorination were examined of which 157 were entirely satisfactory. Of 313 samples of the chlorinated Blithe water 308 were entirely satisfactory. Regular monthly tap samples were examined within the Borough from:— The Company’s Depot, Coleshill Road, Sutton Coldfield, Sutton Coldfield Golf Club, Streetly, and 50 Four Oaks Road, Four Oaks. Twelve samples from the Company’s Depot and eleven each from Streetly and Four Oaks were all entirely satisfactory.
