Lead is a heavy metal, with the chemical symbol of Pb. Lead rose in popularity due to its attributes such as high density, high malleability and low cost. It was used in the production of many consumer products like paint, plumbing materials and ammunition until lead was found to be harmful to human health if ingested or inhaled. Lead is a toxin that accumulates in the body over time and can cause severe damage to the brain, kidneys and nervous system.

Lead in Drinking Water

Lead can enter drinking water through the corrosion of your home's plumbing materials and water lines connecting your home to a water main. Lead solder was banned in the U.S. in 1988. The Lead in Drinking Water fact sheet provides more detailed information.

Ohio law includes requirements related to lead and copper for public water systems and certified laboratories. Ohio EPA reviews standards for lead and copper monitoring, requires timely public notification of monitoring results and ensuring public water systems optimize corrosion control treatment. For details, see the Lead and Copper in Public Water Systems webpage.

Ways to reduce lead exposure to drinking water

Test your water for lead

  • Ohio EPA Certified Labs for Lead and Copper 
  • Contact your utility to see if you are eligible to participate in their compliance sampling.
  • Contact a professional plumber to determining whether your home’s plumbing may contain lead.
  • Consider replacing your home's plumbing with non-lead materials where possible

see if your home has a lead service line connecting to the water main

  • Work with community and water utility officials if your home has a lead service line. It's important to replace these lines in their entirety.
  • Flush the water before drinking.
    • If you have lead water fixtures, lead plumbing materials or a lead service line, flush any time the water has been motionless for four hours or more.
    • If you have a lead service line, flush your water until the line is cleared — about 30 seconds to three minutes.
    • If you have lead fixtures but no lead service line, flush the tap for approximately 30 seconds to three minutes.
  • Clean faucet aerators regularly.
  • Use cold water for cooking and preparing baby formula.
  • Do not cook with or drink water from the hot water tap; lead dissolves more easily in hot water.
  • Do not boil water to remove lead. Boiling water can increase the concentration.
  • Consider a water filter.

Contact Your Water Supplier for Information About Your Drinking Water

Public water systems are required to monitor their water regularly for contaminants. When a system doesn't meet a standard, consumers are notified. Water systems are also required to provide customers with a Consumer Confidence Report each year. Details about these reports, along with details about monitoring and reporting requirements may be found on the Public Water Systems webpage.

In addition, many communities provide information about lead and drinking water to customers online. Contact your water supplier to find out what information they have available. Here are a few examples.
