    WATER SAMPLING. The water samples submitted for examination during the year 1947 were as follows :— Public Supplies : Chemical Bacteriological. Stourbridge and District Water Board High Level Supply . . . — Low Level Supply . 4 Bore Holes. 3 South Staffordshire Water Supply. 1 Private Supplies : Chawn Hill Cottage . 1 Pedmore Hall 2 High Trees, Iverley . 1 6a Hungary Hill . 1 13 PUBLIC SUPPLIES. Without exception the reports on the public supplies, both from the Stourbridge and District Water Board and the South Staffordshire supply, were excellent. Bacteriological counts were very low, whilst chemical examinations have been constant. The supplies were equally satisfactory as to quantity. They are not liable to plumbo solvency but samples are examined periodically for lead contamination. The approximate number of dwelling houses supplied from the Mains direct to the houses was 10576 and by means of standpipes, external to the houses, 90 (approximately). The following are results of the chemical examination of five repre¬ sentative samples of the Town's Water Supply, taken during the year :— Low Level. 20thFeb. 1947 21s/ ]uly, 1947.
