The use of plastic materials was identified as a substitute for metal pipe and components that
release lead into drinking water, but concerns were expressed with regard to the leaching of
organic contaminants such as endocrine disrupting chemicals (EDCs) at drinking water fountains
in Seattle Public Schools. This paper summarizes current information pertaining to potential
risks associated with leaching of organic contaminants from plastic piping materials used in
premise plumbing and storage containers for potable water supplies. Current knowledge
regarding EDCs, chemical additives in plastics (e.g., phthalates, phenolics, and organotins),
environmental exposure, and other emerging contaminants in drinking water are discussed. In
addition, safeguards that are currently in place for protecting human health (NSF/ANSI
Standards for drinking water and food equipment) are considered. Results from this study were
used by Seattle Public Schools to help understand the relative risk of using plastic materials in
place of old end-use plumbing. This paper provides information to utilities that serve
communities with old school buildings. This paper also provides information to individuals who
are curious about current research and developments pertaining to the occurrence and impact of
endocrine disruptors in drinking water systems. Includes 58 references, table.
