A study was undertaken to determine the extent of residual vinyl chloride monomer (VCM) migration from PVC pipe into water. Methods were developed to analyze VCM in water at low levels. Test samples of PVC pipe were exposed to water under static and flowing conditions for varying time intervals. The results indicate that the level of VCM extracted into water is directly proportional to the level of residual monomer in the pipe. Pipe containing <1.0 mg/kg(<1.0 ppm) residual VCM showed no VCM extracted into water with a test sensitive to 0.002 mg/kg (2 ppb).
