Full Description

In this discussion of Alan R. Berens' article on "Prediction of Organic Permeation Through PVC Pipe" (Journal AWWA, November 1985), Crum and Carns state that field experience at East Bay Municipal Utility District confirms Berens' conclusion that PVC pipe is an effective barrier against chemical pollutants, but they point out that more work is needed to verify this conclusion by using actual PVC pipe sections and gasket materials exposed to organic chemicals with activities in the range of 0.25 to 1.0 where Fickian transport assumptions no longer apply.
