Learn About Lead

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 enters drinking water primarily because of the corrosion of materials containing lead in the water distribution system and household plumbing. These materials include lead-based solder used to join copper pipe, brass and chrome-plated brass faucets, and, in some cases, pipes made of lead that connect a building to the water main (service lines). 

Lead can cause serious health problems, especially for pregnant women and young children. Lead in drinking water, although rarely the sole cause of lead poisoning, can significantly increase a person’s total lead exposure, particularly the exposure of infants who drink baby formulas and concentrated juices that are mixed with water. 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

  • 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.

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

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.

General Lead and Copper Info

In 1974, the Safe Drinking Water Act was passed by Congress. This law requires EPA to determine the level of contaminants in drinking water at which no adverse health effects are likely to occur with an adequate margin of safety. Since lead contamination of drinking water often results from corrosion of the plumbing materials belonging to consumers, the EPA establishes a Treatment Technique. The Treatment Technique regulation for lead requires water systems to control the corrosivity of water.

In 2016, Ohio Legislature amended Ohio Revised Code Chapter 6109, adopting new requirements related to lead and copper for public water systems and certified laboratories. On May 1, 2018 new rules became effective.

LCRR Effective Date Extension and Review

On March 12, 2021, U.S. EPA published two notices that impact the effective and compliance dates for the Lead and Copper Rule Revisions (LCRR). The first notice delays the effective date of the LCRR from March 16, 2021 to June 17, 2021. This notice does not change the rule provisions or the compliance date of Jan. 16, 2024. This delay in the effective date is consistent with Presidential directives issued on Jan. 20, 2021, directing the heads of Federal agencies to review certain regulations issued towards the end of the last Administration, including the LCRR. There is no public comment requested and this delay goes into effect as of March 12.

The second notice proposes to further delay the effective date of the LCRR until Dec. 16, 2021 and proposes to delay the compliance date from Jan. 16, 2024 to Sept. 16, 2024. U.S. EPA is asking for public comments on this proposal, which must be submitted by April 12, 2021. If the effective date is delayed until December, U.S. EPA intends to conduct stakeholder outreach throughout the review period to gain additional public input on the LCRR and potential changes to the rule, particularly from communities that are most at-risk of exposure to lead in drinking water. If U.S. EPA decides it is appropriate to propose revisions to the rule, it will consider whether to further extend compliance dates for those specific obligations. U.S. EPA intends to issue a final decision on this proposal prior to the June 17, 2021 effective date.


Lead Service Lines

Ohio EPA, in conjunction with ODH, developed a flushing guidance document for premise plumbing water service restoration. While this guidance was not written specifically for flushing related to potential lead particulate contamination in a house or building, it may be helpful if there is suspected lead particulate from service line or main work near a house or building.

H2Ohio Funding to Replace Lead Service Lines

In September, 2020, as part of Gov. Mike DeWine’s H2Ohio initiative, Ohio EPA awarded $725,000 to the City of Cincinnati for the removal and replacement of lead service lines and lead-containing fixtures at approximately 185 childcare facilities. The Ohio Department of Health also contributed funding for lead fixture testing through a federal award provided by U.S. EPA. read more....

Ohio EPA's Drinking Water Assistance Fund: Lead Service Line Replacement Funding

According to an American Water Works Association article published in 2016, approximately 6.1 million homes across the country receive drinking water through lead pipes, known as lead service lines (LSL). Since 2017, in response to concerns about lead in drinking water, Ohio EPA’s Drinking Water Assistance Fund (DWAF) program has provided no interest financing for LSL replacement. Eligible projects include public LSL replacement activities and costs to replace private lead service lines up to premise plumbing also are eligible. Projects with both public- and private-side lead service lines must include replacement of both lines. Figure 1 outlines the components eligible for funding (see bright green outline). More details are available in this fact sheet.

U.S. EPA's WIIN 2107: Lead Testing in School and Child Care Program Drinking Water

Authorized under the Water Infrastructure Improvements for the Nation Act, the Lead Testing in School and Child Care Program Drinking Water Grant creates a program to assist with voluntary testing for lead in drinking water at schools and child care programs. In the program’s inaugural launch in 2019, the grant included $43.7 million in funding. In it's second year, U.S. EPA will award approximately $26 million for the 2020 Lead Testing in School and Child Care Program Drinking Water Grant Program.
