“Analyzing for Asbestos in Drinking Water”

News of the Environmental Research in Cincinnati, January 16, 1976.


Detecting, identifying, and counting asbestos fibers in drinking water supplies have been the concern for some time of scientists at the Water Supply Research Division (WSRD), a part of the newly formed Municipal Environmental Research Laboratory (MERL) in Cincinnati. During the past year and a half, they have subjected drinking water samples from over 70 cities throughout the United States to this type of analysis. In addition, they have examined samples collected at pilot plants where techniques for removing asbestos from drinking water are being applied. Currently, several water systems that use asbestos-cement distribution lines are being monitored on a bimonthly basis to determine how much, if any, asbestos is released into the drinking water. In conjunction with this study, a 100-foot recirculating asbestos-cement pipeloop was constructed at the laboratory to study the influence that pH, hardness, and alkalinity have on the release of the fibers.
