Abstract Techniques are available to minimize the concentration of asbestos fibers in drinking water. Granular media filtration can remove over 99% of the asbestos fibers found in source waters when the raw water is coagulated properly and effluent turbidity is 0.10 ntu or lower. Asbestos cement pipes can be protected by modifying low pH, low alkalinity waters so they are not aggressive; by coating the pipe wall with a chemical precipitate; or by applying a cement mortar lining to the pipe wall. Modification of distribution system practices related to main flushing and pipe tapping can also reduce the fiber count in tap water.
