Abstract

Develops highly sensitive methods for quantification of vinyl chloride (VC) and organotins (OTs). Determines VC and OT leaching rates and equilibrium concentrations in tap water contacting unplasticized poly-vinyl chloride (PVC) pipe. Investigates effects of pipe type (PVC and chlorinated PVC [cPVC]), incubation temperature, biofilm coverage, pipe age, and flow regime on VC and OT levels measured in tap water. Determines VC and OT levels in tap water from houses equipped with PVC and cPVC lines of varying ages, types, diameters, and lengths and with different water sources. Published in 2009.
