Untreated waters from ten farm ponds located in central, north central, southeastern, and southwestern Ohio were examined for numbers of coliforms, enterococci, thermodurics, thermophiles, and psychrophiles. The median population densities per 100 ml water for all ponds were: coliforms, 23; enterococci, 3.6; thermodurics, 6,000; thermophiles, 450; psychrophiles, 1,000. The results indicate that these farm pond waters were only lightly polluted and suggest that farm ponds, properly maintained, are a source of raw water of high bacteriological quality, requiring a minimum of treatment to be made suitable for domestic and livestock purposes.
对位于俄亥俄州中部、中北部、东南部和西南部的10个农场池塘的未经处理的水进行了大肠菌群、肠球菌、耐热菌、嗜热菌和嗜冷菌数量的检测。所有池塘每100毫升水中的中位数种群密度为：大肠菌群23；肠球菌3.6；耐热菌6000；嗜热菌450；嗜冷菌1000。结果表明，这些农场池塘水仅受到轻度污染，并表明适当维护的农场池塘是细菌学质量高的原水来源，只需进行最少的处理就适合家庭和牲畜使用。
