With so many houses equipped with automatic clothes and dishwashers, plus the American penchant for frequent bathing, by far the greater volume of sewage entering septic systems is “gray sewage.” Septic tanks left to handle “night soil” only should be able to handle the job indefinitely.

THE NEW INDUSTRY STANDARD FOR AIR POLLUTION MONITORING

Daniel P. Dash 113 Killarney Rd. Knoxville. Tenn. 37919 DEARSIR: Unfortunately, your sincerity and enthusiasm are matched by your naivete on the subject of “strong-smeliing cheinical toilets.” If you have traveled on any commercial jet airliner in the past ten years, the toilet facility was undoubtedly a recirculating chemical toilet. Yet, I am sure that it was certainly not offensive to any of your senses. Most such modern toilets use only an initial charge of four gallons of water and an effective deodorant. The rest of the fluid used to flush with is a diluted, filtered urine solution.

Nathan J. Krotinger, president Zevel Corp. La Mirada, Calif. 90638 Several makers and users of chemical toilets have sent us favorable comments on use of these units-Ed. DEARSIR: In order to determine whether research funds might have been available to study the concept raised in Mr. Leich’s Viewpoint, I contacted two federal agencies in September 1970. Their responses were negative. One stated that “it has been suggested many times” and emphasized that handling, hauling, and final disposal were the unsolved problems in this area. The other’s response was that “limited research funds and program priorities” prevented their consideration of the concept. Perhaps a coordinated approach to environmental research by EPA will include further studies on elimination of problems as well as treatment of problems.
