Recently, there has been both state and national attention to lead in drinking water. If present, elevated levels of lead can cause health problems, especially for pregnant women and young children. Lead typically enters the drinking water due to the corroding of materials and components beyond the City's delivery point, which includes private service lines and internal plumbing of homes and buildings. The City of Chandler is committed to providing safe, high-quality drinking water to its citizens, but cannot control the variety of materials used in home or commercial plumbing components.
To help ensure lead safety, the City of Chandler adheres to the EPA's Lead and Copper Rule by meeting all sampling and reporting requirements. Results from those samples show that Chandler continues to remain well below the EPA action levels for lead and copper.
More information on lead in drinking water is available on the EPA's website.
Chromium-6 can be naturally occurring, or the result of certain industrial activities such as metal plating. The U. S. Environmental Protection Agency (EPA) limits Chromium-6 as part of total chromium limits. The current limit for total chromium is 100 parts per billion (ppb). Chandler's total chromium levels are well below the EPA standard, averaging 5.32 ppb (nearly 95 percent below the current allowable limit set by the EPA). For more information on Chromium-6 in drinking water, visit the information on Chromium in Drinking Water on the EPA's website.
