Monitoring lead in water is nothing new and at the same time vitally important. In 1991, the Environmental Protection Agency (EPA) implemented a Lead and Copper Rule (LCR), which included tap-water monitoring, water quality regulations, and industry trends to protect the public from consuming lead and high levels of copper.
While these regulations apply to new plumbing installation and repairs, they historically did not address existing water service lines installed or repaired before 1986, when the Safe Drinking Water Act prohibited using any pipe, plumbing fitting or fixture, solder, or flux in public water systems that are more likely to have some lead plumbing.
In 2021, the EPA revised the LCR, creating the Lead and Copper Rule Revision (LCRR), which addressed existing water pipes installed before 1986. The LCRR directed all public utilities in the US to inventory water service lines extending from water mains to each customer’s home or business. This better protects communities from exposure to lead in drinking water and ensures lead is not found in the country's water-service lines.
In 2023, the EPA improved the LCRR by developing the Lead and Copper Rule Improvement (LCRI). These improvements outline lead pipe identification and replacement with public utilities and improved sampling requirements.

Lead and Copper Rule Revision Timeline
| Lead and Copper Rule (LCR) | Lead and Copper Rule Revision (LCRR) | Lead and Copper Rule Improvement (LCRI) |
| Passed in 1991 | Passed in 2021 | Proposed in 2023 |
|
Required public water systems to: Reduce levels of lead and copper in drinking water. Establish lead monitoring goals, such as a Maximum Contaminant Level Goal of zero for lead. Established a treatment technique, such as corrosion control, to prevent lead from entering water. Required public education about the risks of lead in drinking water. |
Requires public water systems to: Provide an Initial Service Line Inventory (ISLI) to the state by October 16, 2024. Make an ISLI Dashboard publicly available and searchable online. Notify all customers with service lines classified as lead, galvanized requiring replacement, or unknown no more than 30 days after the ISLI is submitted. Notify all customers within 24 hours if 90th percentile lead level exceeds the lead action level of 15 μg/L. |
The LCRI takes effect effect in January 2028 and requires public water systems to: Regularly update its service line inventory and identify the materials of all service lines of unknown material within 10 years. Replace all lead service lines within 10 years. Complete sampling and testing for all school and childcare facilities within five years. Take specific actions when the lead action level (AL) is at least 10 μg/L. |
Note: No Lead Drinking Water Test have tested positive for lead, nor have any lead service lines been identified during the City’s field investigations.
For years, the City's water testing has shown the water is safe and meets or surpasses all state and federal water quality standards. This includes testing for lead to ensure water is safe to drink. The City's underground water mains under do not contain lead, and the City has no known lead service lines leading from mains to meters. The City's water distribution system is in full compliance with EPA's current regulations.

Lead water pipes may still exist in the City's system, particularly on private property with older homes and businesses. Of the City's approximately 112,000 water service lines, 30,000 lines were installed in the 1980s after North Carolina banned lead in service lines.

|
| 1st quarter 2026 |
City will contact customers to schedule a field investigation using vacuum excavation to visually confirm GRR.
|
|
4th quarter of 2026 |
City will replace all verified GRR, with the oldest buildings replaced first.

To verify if and where lead service lines exist on private property, the Water Resources Department has launched a voluntary online Lead & Copper Program Survey (En español) with easy-to-follow instructions to identify your service line material. Follow the steps provided and report your findings. If you discover lead or potential lead, follow these steps. (En español).
Questions? Check out our FAQs.
Have your water tested.
Note: No buildings have tested positive for Lead for during the City’s field investigations.
In 1986, new regulations prohibited the use of any lead pipe, plumbing fitting or fixture, solder, or flux in public water systems. However, existing water service lines installed or repaired before 1986 have the potential for some or all of the service line be made of lead or galvanized pipe previously connected to lead.
If your building existed before 1986 and you have not replaced your service line and would like to request a lead test kit complete the online Lead (Pb) and Copper (Cu) Drinking Water Test Request Form. Questions? Email us or call the laboratory at 336-373-7527.
Alternatively, you may contact a certified laboratory to have your water tested for lead. Note, a water sample may not adequately capture or represent all sources of lead present.

As part of the Lead and Copper compliance program, the City conducted randomly selected private sites for field investigations. The City used the vacuum excavation method to physically verify a subset of unknown water service line material. These customers in the Greensboro service area received the Vacuum Excavation Letter with the City's Right-of-Entry QR code (ROE). This letter asked customers to allow a City contractor to perform a test to identify the private service pipe material. The City completed the vacuum excavations in February 2025, all customers can see their water service line classification in the Service Line Inventory dashboard.
The City is fully committed to complying with the Environmental Protection Agency (EPA) regulations and will cover the replacement cost of all galvanized requiring replacement (GRR) water service lines from the water meter to the customer’s building.
Once the ROE is signed, the respective utility companies will mark yards with spray paint or flags to indicate the location of utilities. Shortly after that, the City's contractor arrives to start the test, which will confirm both the customer's and City's water pipe material.
The excavation begins with a small hole dug about five feet from a customer's water meter on their property. Another hole will be dug in the City’s right-of-way. This test is the least-invasive method for identifying pipe material. Contractors will restore the dig site to its previous condition as much as possible (example below).
Your participation is a crucial component of our Lead and Copper Compliance Program. Knowing what materials water service lines are made of helps Water Resources inventory those lines and identify potential risks of lead exposure.
Vacuum Excavation Explained Video
Predictive Model Explained The selection of water service lines for vacuum excavation or physical verification is random. In other words, all unknown service lines within the system should have an equal chance of selection for verification. The subset of service lines selected meets the North Carolina Department of Environmental Quality (NCDEQ) requirement for using statistical methods and predictive modeling to develop service line inventory.
The subset of service lines selected were based on the following:
- Year of construction
- Parcel information
- Nearest water main or hydrant data
- Meter data from the customer or one nearby
- Historic replacement or other work order records
- Census data
