Lead & Copper Monitoring

The City of Newark Water Treatment Plant performs lead and copper testing as required by the EPA. To monitor compliance with the regulation the City must sample water from individual homes.  Sampling locations are selected based on the potential for lead components in the home plumbing system.  Per EPA requirements, the City monitors 30 homes every 3 years.  Residents in homes where samples are taken are notified of the results of those tests.  If lead concentrations exceed an action level of 15 ug/L or copper concentrations exceed an action level of 1.3 mg/L in more than 10% of customer taps sampled, the system must undertake a number of additional actions to control corrosion.

If the action level for lead is exceeded, the system must inform the public about steps they should take to protect their health and take actions to control the lead levels.

The City of Newark’s levels of lead and copper are well below the action level.  Each year this information along with other important information is published in the Consumer Confidence Report (CCR). This report can be found on the City’s website. Click here to view the current CCR.


Testing Your Homes Drinking Water

Testing your home's drinking water is the only way to confirm if lead is present. Most water systems test for lead at a certain number of homes as a regular part of water monitoring. These tests give a system-wide picture of whether or not corrosion is being controlled but do not reflect conditions at each home served by that water system. Since each home has different plumbing pipes and materials, test results are likely to be different for each home.
You may want to test your water if:

  • your home has lead pipes (lead is a dull gray metal that is soft enough to be easily scratched with a house key), or
  • your non-plastic plumbing was installed before 1986.

You can buy lead testing kits in home improvement stores to collect samples to then send to a laboratory for analysis. EPA recommends sending samples to a certified laboratory for analysis; lists are available from the Ohio EPA. Your water supplier may also have useful information, including whether the service line connecting your home to the water main is made of lead.
Find local contact information for testing your water for lead by calling EPA's Safe Drinking Water Hotline at 800-426-4791.

If Your Home Tests Positive for Lead:

  • Flush your pipes before drinking, and only use cold water for cooking and drinking.  Anytime the water in a particular faucet has not been used for six hours or longer, flush your cold-water pipes by running the water until it becomes cold. Contact your water utility to verify flushing times for your area.
  • Consider replacing lead-containing plumbing fixtures. If you are considering this, keep in mind that the Safe Drinking Water Act (SDWA) requires that only lead-free pipe, solder, or flux may be used in the installation or repair of a public water system, or any plumbing in residential or non-residential facility providing water for human consumption. "Lead-free" under the SDWA means that solders and flux may not contain more than 0.2 percent lead, and pipe, pipe fittings, and well pumps may not contain more than 8.0 percent lead. Beginning January 2014, changes to the Safe Drinking Water Act will further reduce the maximum allowable lead content of pipes, pipe fittings, plumbing fittings, and fixtures to 0.25 percent.

SDWA also requires plumbing fittings and fixtures intended to dispense water for human consumption (e.g., kitchen and bathroom faucets) meet a lead leaching standard. Those fittings and fixtures should be certified according to NSF/ANSI Standard 61 for lead reduction.

  • Consider alternative sources or treatment of water. If you discover that you have high levels of lead in your home, you should consider using bottled water or a water filter. There are many home water filters that are certified for effective lead reduction, but devices that are not designed to remove lead will not work. Verify the claims of manufacturers by checking with independent certifying organizations. NSF International and the Water Quality Association provide lists of treatment devices they have certified. Underwriters Laboratories is also a good resource for certified devices. Be sure to maintain and replace a filter device in accordance with the manufacturer's instructions to protect water quality.

Refer to the manufacturer's instructions for maintenance procedures. If not maintained properly, some treatment devices may increase lead and other contaminant levels.
