§ Mr. Adleyasked the Secretary of State for Social Services if, in view of health hazards caused by the water strike, he will immediately investigate the properties of hypochlorite to assess its suitability as a sterilising agent for purifying water.
§ Mr. Geoffrey FinsbergThe properties of hypo-chlorite are known. Under controlled conditions hypochlorite is an effective method of making water safe and is commonly used in water treatment plants. However, problems may occur if too much or too little is used to treat water for consumption and the average household does not have the means of estimating the correct amount to use. In present circumstances, where it is necessary and possible, boiling the water vigorously for one minute is recommended as being simple and wholly effective.
