Dr. William W. Burr, dr. December 7, 1977 Page 2 trust territory health officials should be informed of these preliminary results. More important, some purification system, easy to use, should be considered for the water systems. Something should be done about the existing cisterns and open wells and some thought might be given to the design of future cisterns planned for the residential housing on Enyu. I asked the district representative at Bikini if many of the people suffered from dysentery. He toid me that many people did and I recommended that he inform the population to boil the drinking water before use until a more rigorous inspection of the water supply could be made. Unfortunately we were both out of time and suitable sterilized containers to conduct more sampling. Roger Ray indicated he would inform Oscar DeBrum of our results and recommend to the health officials that a more detailed investigation of the microbiological contamination of the water supplies should be conducted in the immediate future.
