Understanding Lead Risk in Oklahoma City’s Drinking Water
Lead is a toxic metal that poses serious health risks — particularly to children and pregnant women. In Oklahoma City, the risk of lead in drinking water isn’t from the water source itself, but rather from the service lines and plumbing in homes and businesses. OKC’s Lead-Safe OKC program, managed by the Utilities Department, is actively working to identify those risks and inform utilities customers.
How does lead get into drinking water?
Lead enters drinking water primarily through the corrosion of lead service lines and older household plumbing materials, including lead solder, brass fixtures, and galvanized pipes that can release accumulated lead particles. Factors such as acidic or low-mineral water, hot water, stagnant water, or ineffective corrosion control can increase lead leaching. Disturbances from water main work, plumbing renovations, or partial pipe replacements can also cause temporary spikes in lead levels, while changes in water chemistry—such as switching water sources—may strip protective pipe coatings and increase corrosion. Although less common, private wells may contain lead if pumps or plumbing components include lead or if acidic groundwater dissolves metals. Understanding these sources is essential for reducing lead exposure and ensuring safer drinking water.
What the EPA’s Lead & Copper Rule Means for OKC
Water systems are required by the EPA to create a service line inventory, classifying lines as lead, galvanized requiring replacement, non-lead, or unknown. Additionally, utilities were required to notify customers of the type of service line material for both the public side (utility-owned) and private side (owner-owned) by November 2024. When lead levels exceed thresholds, utilities must issue Tier 1 Public Notices within 24 hours to alert affected residents.
How OKC Is Responding — Lead-Safe OKC Efforts
The city launched a Lead-Safe Community Database, where residents can look up their property to see if their service lines are made of lead, galvanized steel, or other materials. As of October 2024, 173 public service lines in OKC have been confirmed as lead — a very small fraction (just 0.07%) of the city’s ~254,000 service accounts. OKC is using physical inspections, historical records, and self-reporting from residents to verify the materials of unverified lines. Ongoing effort is being made to identify unverified lines.
What You Can Do as an OKC Resident
- Check Your Service Line: Use the Lead-Safe Community Database to see what your service line is made of.
- Install a Certified Filter: Use a water filter that is certified to reduce lead such as a whole house water filtration systems or reverse osmosis system from Culligan and follow maintenance instructions.
- Consider Testing Your Tap: If you’re concerned, you can have your tap water tested for lead by Culligan.
- Report Service Line Info: If you know your private service line’s material, you can self-report it to help OKC’s inventory.
