Provisional potable water standards, patterned after the 1962 USPHS Drinking Water Standards, were formulated for application to aerospace systems. In comparison with USPHS standards, the recommended maximal allowances have been raised relaxed at least 80, with the majority increased from two- to five-fold, for the following 16 out of 20 chemical constituents alkyl bensene sulfonate, arsenic, barium, cadmium, chloride, copper, cyanide, iron, lead, manganese, nitrate, phenols, selenium, silver, total dissolved solids, and zinc. Four constituents, carbon chloroform extract, chromium, fluoride and sulfate, remain relatively unchanged. The radiological requirements are the same as USPHS for radium226, strontium90 and gross beta emitters. The only change in the physical properties concerning turbidity, color, odor and taste in these standards as compared with USPHS is a fivefold increase in the turbidity level. For the microbiological quality of water, it has been recommended at this time that the potable water be free of all microorganisms to minimize potential health hazards to aerospace personnel. The importance of selection of materials for aerospace systems, improvement in analytical methods e.g., detection of organic contaminants, and resolution of problems needing attention to the development of permanent potable water standards is discussed.
