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.
