Lead Action Level FAQs
What is an action level?
Action level is a term used by water utilities to describe the effectiveness of a system’s corrosion control treatment to reduce lead in drinking water. Utilities routinely collect and analyze samples from their system to check if corrosion control is working. Utilities compare the sample results to the EPA standard of 0.015 mg/L (15 ppb). When 10% of samples exceed the EPA action level, water utilities must complete actions which include adjusting water treatments, public education, and service line replacement.
Did the City sample water in my home or building for lead?
The City collected 100 samples between January and June 2025. If the City sampled your home or building during this time, you will receive sample results.
Does an action level exceedance (ALE) mean my drinking water contains lead?
No. The ALE does not mean that all drinking water in our system contains lead. However, it requires that the entire community be notified.
What is the City doing to reduce lead exposure?
The City is completing the following actions in response to the ALE:
• Ongoing sampling to monitor lead occurrence and levels throughout the water distribution system
• Public education to assist homeowners with actions they can take individually to reduce exposure to lead
• Ongoing removal of lead service lines throughout the City
• Evaluation of corrosion control methods. The City is studying ways to reduce the amount of lead that pipes and plumbing fixtures release in the drinking water
