The influence of an educational fact sheet on small system water supplier attitudes toward the lead and copper rule.
In May 1991, the EPA established the lead and copper rule (1). The purpose of this new environmental regulation is to reduce lead and copper in drinking water and to inhibit corrosion of water distribution pipes. This new rule requirement is due to the findings of several studies regarding the widespread and adverse health impact that ingested lead and copper can have on children and adults.
Lead is widely used in drinking water distribution systems and in household plumbing systems. Nationally, there are approximately 4 million lead service line pipes in use (2) and Detroit has approximately 100,000 lead service lines in use which constitutes one-third of the service lines (3). Lead pipes were used because they are very corrosion resistant due to the lead carbonate film that forms on pipe surfaces. Unfortunately, the water used can result in increased solubility of the lead carbonate and increased leaching (extraction and dissolution) of lea...See the full content of this document
