Full Description

It has long been known that organic contaminants may permeate through plastic pipes andadversely affect the quality of drinking water in a distribution system (Vonk, 1985; Thompsonand Jenkins, 1987). The plastic pipe materials involved include polybutylene (PB), polyethylene(PE) and polyvinyl chloride (PVC) and the contaminants of interest include highly volatilehydrocarbons and chlorinated organic solvents (Holsen et al., 1991a). In this study, the permeation of petroleum-based aromatic compounds (BTEX) through PE pipewas investigated under simulated field conditions, including subsurface gasoline spills andgasoline-contaminated groundwater with varied levels of contamination. Most of the pipepermeation incidents reported were related to petroleum products, mainly gasoline spills or leaks(Holsen et al., 1991a). The effects of soil organic matter content on permeation were alsoexamined. The main purpose of this study was to develop empirical equations which can be usedto predict the permeation behavior of BTEX through PE pipe at contaminant levels typicallyfaced in the environment. Includes 8 references, table, figures.
