AB - VARIATION WITHIN THE COLON-AEROGENES GROUP AS FOUND IN BACTERIOLOGIC ANALYSIS OF WATER FROl\1 CONTAMINATED PUMPS LELAND W. PARR WASHINGTON, D. C. AND ELFREDA L. CALDWELL ANDALUSIA, ALA. Since 1929 this laboratory has studied the effect on the potability of shallow ground waters of the introduction of fecal material into that water through "bored hole" latrines. Samples of water for this study have been obtained from concrete-set driven pipe wells reaching to depths of from 13 to 24 feet (4 to 7.3 meters). These wells are located at varying distances and in varying directions from a latrine receiving routine addition of feces. Plots with wells but no latrine serve as controls. Water is drawn through Myer's force pumps pro­ vided with cut-off faucets, torch-sterilized before each sampling. Of more than 29,000 samples of water from the wells located in the experimental plots, a certain number have yielded positive colon­ aerogenes findings not consonant with the results of the epidemiologic survey and biochemical analysis. These samples have been found to come from pumps drawing ground water free from colon-aerogenes organisms but delivering water heavily contaminated therewith. This contamination was introduced into the water as it passed through the pump and originated
