Several residents had bores drilled, but over half (1000) relied on tank water. A 2½ in. bore behind the Harbour View Hotel had /day rising to about below the surface, though rather hard and tinged with iron. Of its the first 50 ft. was in clay, 4 ft. in hard blue shingle tightly packed with a minimum of sandy matrix and 106 ft in papa. The deep, 3 in. bore for the dairy factory, 70 ft. above sea-level in Rose St, was polluted with ammoniacal nitrogen and chlorides too were high.
