研究了几种用于润滑油井泵的油，以评估它们对地下水中可同化有机碳（AOC）的相对贡献。这项研究的目的是确定使用油润滑的井泵系统是否会导致配水系统中的细菌生长。在添加各种类型的泵润滑油之前和之后，使用改进的van der Kooij程序测试无菌自来水样品中的AOC浓度。结果表明，某些润滑油可以向水中释放大量的细菌营养素（AOC）。润滑油的选择可能与某些系统中的细菌生长问题有关。包括4个参考文献、表格。

Several types of oil for lubricating well pumps were examined to assess their relative contribution to assimilable organic carbon (AOC) in groundwater. The objective of the study was to determine whether the use of an oil-lubricated well-pump system could contribute to the growth of bacteria in water distribution systems. A modified van der Kooij procedure was used to test the AOC concentration in sterile tap-water samples before and after the addition of various types of pump-lubricating oil. The results showed that certain lubricating oils could release substantial levels of bacterial nutrients (AOC) into the water. The choice of lubricating oil could be related to bacterial growth problems in some systems. Includes 4 references, tables.
