AB  - Pipes constructed with high-density polyethylene (HDPE) or chlorinated polyvinyl 
      chloride (cPVC) are commonly used in drinking water distribution systems and 
      premise plumbing. In this comprehensive investigation, the effects on odor, 
      organic chemical release, trihalomethane (THM) formation, free chlorine demand 
      and monochloramine demand were determined for water exposed to HDPE and cPVC 
      pipes. The study was conducted in accordance with the Utility Quick Test (UQT), a 
      migration/leaching protocol for analysis of materials in contact with drinking 
      water. The sensory panel consistently attributed a weak to moderate intensity of 
      a "waxy/plastic/citrus" odor to the water from the HDPE pipes but not the 
      cPVC-contacted water samples. The odor intensity generated by the HDPE pipe 
      remained relatively constant for multiple water flushes, and the odor descriptors 
      were affected by disinfectant type. Water samples stored in both types of pipe 
      showed a significant increase in the leaching of organic compounds when compared 
      to glass controls, with HDPE producing 0.14 microgTOC/cm(2) pipe surface, which 
      was significantly greater than the TOC release from cPVC. Water stored in both 
      types of pipe showed disinfectant demands of 0.1-0.9 microg disinfectant/cm(2) 
      pipe surface, with HDPE exerting more demand than cPVC. No THMs were detected in 
      chlorinated water exposed to the pipes. The results demonstrate the impact that 
      synthetic plumbing materials can have on sensory and chemical water quality, as 
      well as the significant variations in drinking water quality generated from 
      different materials.
