Efficient chlorination should yield water entirely free from such organisms in quantities of 100 m.l., and such results as those 1 above, in the opinion of the expert advisers to the Ministry of Health, should at once occasion misgivings as to the adequacy of the chlorinatiojl process. SWIMMING BATH. This open air pool holds 75>000 gallons of water and is filled and drained at fortnightly intervals. It has been customary to add 3 pints I of a concentrated hypochlorite solution to the bath water daily since the average load of bathers per day is about 150. The surround drains mainly to the bath and pre-cleansing facilities such as footbaths or ■ showers are not provided. A separate v/ater closet is available for each 1 sex plus a urinal. * • It is admitted that since the pool is open to the atmosphere, sunshine acts as a potent germicidal medium but the bath is lacking in facilities now regarded as essentials. Until a continuous chlorination and filtration plant can be installed I recommend that the water be changed more frequently and that footbaths and showers be provided in such positions that they must be used by bdthers before entering the bath* The chlorination should be controlled according to the bathing load so as to maintain a minimum of 0.2 parts per million cnlorine residual at all times and a record kept of tests performed to ensure this standard is observed. Optimum conditions will only be obtained by the installation of continuous' filtration and chlorination plant. /•](https://iiif.wellcomecollection.org/image/b30234360_0014.jp2/full/800%2C/0/default.jpg)
