The review of available data on the concentrations of asbestos in U.S. water supplies suggests that the majority of water consumers are not exposed to asbestos concentrations over 1 million fibers per liter. A few populations, however, may be exposed to concentrations over 1 billion fibers per liter. Eight percent of the 538 water supplies for which waterborne asbestos data is available have concentrations of fibers over 10 million fibers per liter. The vast majority of asbestos fibers which are found in U.S. water supplies are under 5 micrometers in length.
