The Environmental Protection Agency (EPA) finalized the Lead and Copper Rules Revisions (LCRR) with an effective date of Dec. 16, 2021. Scottsdale Water has been in compliance with the original Lead and Copper Rule (LCR) since 1991 and will
continue to work with the Arizona Department of Environmental Quality to implement the new requirements of the LCRR. The LCRR requires all community water systems to complete a material inventory of all public (city owned) and private (customer
owned) service lines no later than Oct. 16, 2024. This will be the first time the city is required to identify the material for the entire length of the service line to a customer’s home.
Background
Sources of lead are not typically found in groundwater or surface water supplies. Sources of lead in water are most often from household plumbing fixtures/pipes or service lines. The use of lead in pipes and plumbing materials was banned in the
1986 Safe Drinking Water Amendments with an effective date of June 1988. Therefore, homes built after 1989 should not have plumbing materials containing lead. The LCRR requires all lead and galvanized service lines to be identified in the
inventory. Scottsdale has been actively removing public galvanized lines for several years.
Goal
The goal is to complete the EPA required inventory of all service lines by the compliance date of Oct. 16, 2024, and identify any public and private service lines that could be possible sources of lead. Scottsdale Water does not anticipate finding
any lead service lines and will continue the removal of all public galvanized lines.
Process
Scottsdale Water is working with a contractor to identify the material of public and private service lines installed prior to 1989. There are over 45,000 service lines that will need to be surveyed over the next two and half years. The contractor
will make visual observations on both sides of the water meter and at the line entering the home located at the hose bib attached to the house as shown in figure below. Scottsdale Water will work with the contractor to prioritize homes with a
higher risk of possible lead sources. If you have concerns about lead in your home, please call 480-312-8732 or email.
There are only a few options available to perform this inventory and the decision was made by the City to use the least disruptive method. Scottsdale has hired contractors, Hydra Contractor and MSI (badge logos shown below), to document and
photograph the visible pipe materials on both sides of the water meter and at the hose bib at individual homes. The photographs are necessary to prove inventory performance. The inventory must be complete and submitted to the Arizona Department of
Environmental Quality no later than October 2024.
City contractors wear badges with their company's logo.

Results
All results will be made available to the public once the inventory is complete. More information can be found at epa.gov/lead
