Lead in TVWD’s Water: What You Need to Know
Many water systems, including TVWD, have been in the news lately concerning lead in drinking water. The crisis in Flint, MI has resulted in reporters researching lead levels in water systems across the nation. The good news is that TVWD has been in compliance with the Lead and Copper Rule since the inception of the rule nearly 20 years ago. In addition, the TVWD water distribution system does not contain lead service lines, which were a big part of the problem in Flint, MI. TVWD takes water quality, including lead testing, very seriously and supports increasing public awareness and understanding of lead in water.
TVWD's compliance with the Lead and Copper Rule is evaluated every six months based, in part, on water samples collected as part of the regional Joint Monitoring Program. The Joint Monitoring Program is a collaborative effort by water systems in the Portland-metropolitan region to test homes known to have plumbing with lead solder, the most common source of elevated lead in drinking water in our community. The Joint Monitoring Program was approved by the Oregon Health Authority, the regulatory agency which oversees drinking water.
TVWD is a member of the Joint Monitoring Program because a portion of the water delivered to TVWD customers is purchased from the Portland Water Bureau. Participating in the Joint Monitoring Program provides many benefits, including shared costs of lead monitoring and community education. As part of the Joint Monitoring Program, lead test results are aggregated with all the participating water agencies and reported to the state as a single, combined set of data. Therefore, elevated results from one water supplier count against everyone participating in the Joint Monitoring Program. Since 1999, individual results from homes in the TVWD service area that are sampled as part of the Joint Monitoring Program have been well below the Environmental Protection Agency action level for lead. In contrast, the aggregated lead results from throughout the region have occasionally been at or slightly above the action level.
TVWD continues to evaluate options for the best approach to monitoring for lead in water that is representative of the water served in the District's service area, while still deriving all of the benefits of the Joint Monitoring Program. For more information about TVWD's water quality, including actions you can take to help reduce your exposure to lead, visit our Water Quality web page or call 503-848-3000.
