Both EOWC and AW test for lead and copper and neither organization has exceeded the EPA thresholds for compliance with the federal Lead and Copper Rule. It should be noted that the most common source of lead in tap water comes from the corrosion of piping on the customer side of the service connection (i.e. the outdoor service line or the internal plumbing). American Water takes steps to minimize the corrosiveness of its water through improvements in corrosion control. Nevertheless, if you are concerned about the possible presence of lead or copper in your home’s water or for more information on reducing lead exposure around your home, visit the EPA’s Web site at www.epa.gov/lead, call the National Lead Information Center at 800-424-LEAD, or contact your health care provider.
