Plastic pipes, organic coatings and membranes, and epoxy relining products are progressively replacing existing traditional metallic or cementitious materials. Despite existing controls, and for different reasons, additives, solvents, or monomers can be leached into the drinking water. Until ten years ago, such problems frequently occurred. French regulations now oblige the manufacturers to obtain approvals for their products for contact with drinking water, and such problems now occur less and less. The objectives of this research were to investigate the causes of odor and flavor problems generated in distribution systems, water towers, and lined systems. Four case studies and an experimental study of taste and odor deterioration of water quality are presented to identify the responsible substances related to materials. In each case study, organic components which characterized the cause of the problems were measured experimentally. Components (e.g., styrene and chlorinated by-products) resulting in a high TON/TFN were identified as the chemicals responsible for the cause of odor and flavor problems.
