Lead can cause serious health problems, especially for pregnant women and young children. Lead in drinking water is primarily from materials and components associated with service lines and home plumbing. Town of Lillington is responsible for providing high quality drinking water and removing lead pipes but cannot control the variety of materials used in plumbing components in your home. You share the responsibility for protecting yourself and your family from the lead in your home plumbing. You can take responsibility by identifying and removing lead materials within your home plumbing and taking steps to reduce your family's risk. Before drinking tap water, flush your pipes for several minutes by running your tap, taking a shower, doing laundry or a load of dishes. You can also use a filter certified by an American National Standards Institute accredited certifier to reduce lead in drinking water. If you are concerned about lead in your water and wish to have your water tested, contact Public Works Department at 910-893-0318. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available at http://www.epa.gov/safewater/lead
contaminant monitoring is to assist EPA in determining the occurrence of unregulated contaminants in drinking water and whether
future regulations are warranted.

The North Carolina Department of Environment Quality (DEQ), Public Water Supply (PWSS) Section, Source Water Assessment Program (SWAP) conducted assessments for all drinking water sources across North Carolina.
The purpose of the assessment was to determine the susceptibility of each drinking water source (well or surface water intake) to Potential Contaminant Sources (PCSs).
The relative susceptibility rating for Harnett Regional Water (HRW) was determined by combining the contaminant rating (number and locations of PCSs within the assessment area) and the inherent vulnerability rating (i.e., characteristics or existing conditions of watershed and its delineated assessment area.) The assessment findings are summarized in the table below:
Source Name | Susceptibility Rating | SWAP Report Date |
CAPE FEAR RIVER | Moderate | 9/10/2020 |
DUNN/CAPE FEAR RIVER | Higher | 9/10/2020 |
Help Protect Your Source Water
Protection of drinking water is everyone’s responsibility. You can help protect your community’s drinking water source(s) in several ways: (examples: dispose of chemicals properly; take used motor oil to a recycling center, volunteer in your community to participate in group efforts to protect your source, etc.)
Important Definitions
Not-Applicable (N/A) – Information not applicable/not required for that particular water system or for that particular rule.
Non-Detects (ND) - Laboratory analysis indicates that the contaminant is not present at the level of detection set for the particular methodology used.
Parts per million (ppm) or Milligrams per liter (mg/L) - One part per million corresponds to one minute in two years or a single penny in $10,000.
Variances and Exceptions – State or EPA permission not to meet an MCL or Treatment Technique under certain conditions.
Action Level (AL) - The concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow.
Treatment Technique (TT) - A required process intended to reduce the level of a contaminant in drinking water.
Maximum Residual Disinfection Level (MRDL) – The highest level of a disinfectant allowed in drinking water. There is convincing evidence that addition of a disinfectant is necessary for control of microbial contaminants.
Maximum Residual Disinfection Level Goal (MRDLG) – The level of a drinking water disinfectant below which there is no known or expected risk to health. MRDLGs do not reflect the benefits of the use of disinfectants to control microbial contaminants.
Locational Running Annual Average (LRAA) – The average of sample analytical results for samples taken at a particular monitoring location during the previous four calendar quarters under the Stage 2 Disinfectants and Disinfection Byproducts Rule.
Running Annual Average (RAA) – The average of sample analytical results for samples taken during the previous four calendar quarters.
Level 1 Assessment - A Level 1 assessment is a study of the water system to identify potential problems and determine (if possible) why total coliform bacteria have been found in our water system.
Level 2 Assessment - A Level 2 assessment is a very detailed study of the water system to identify potential problems and determine (if possible) why an E. coli MCL violation has occurred and/or why total coliform bacteria have been found in our water system on multiple occasions.
Maximum Contaminant Level (MCL) - The highest level of a contaminant that is allowed in drinking water. MCLs are set as close to the MCLGs as feasible using the best available treatment technology.
Maximum Contaminant Level Goal (MCLG) - The level of a contaminant in drinking water below which there is no known or expected risk to health. MCLGs allow for a margin of safety.

Harnett Regional Water is pleased to present the 2024 Annual Drinking Water Quality Report. This report is a snapshot of last year's water quality and includes information regarding where your water is coming from, what it contains, and how it compares to standards set by regulatory agencies. Our constant goal is to provide you with a safe and dependable source of drinking water. We want you to understand the efforts we make to continually improve the water treatment process and protect our water resources. We are committed to ensuring the quality of your water and to provide you with this information, because informed citizens are our best allies. If you have any questions about this report or your water supply, please contact Tracy Tant at (910-893-7575 ext. 3245). We want our valued customers to be informed about their water utility. If you want to learn more, please attend any of the regularly scheduled Harnett County Board of Commissioners meetings. They are held on the first and third Monday of each month at the Harnett County Resource Center and Library at 455 McKinney Parkway in Lillington, NC. The first meeting of the month is normally at 9:00 a.m. and the midmonth meeting normally begins at 6:00 p.m.
When You Turn on Your Tap, Consider the Source
The water that is used by this system comes from the Cape Fear River, which is formed by the confluence of the Deep, and Haw River along the border between Chatham and Lee counties. We are a surface water treatment plant located at 310 West Duncan St. in Lillington, N.C.
Source Water Assessment Program (SWAP) Results
The relative susceptibility rating for Harnett Regional Water (HRW) was determined by combining the contaminant rating (number and locations of PCSs within the assessment area) and the inherent vulnerability rating (i.e., characteristics or existing conditions of watershed and its delineated assessment area.) The assessment findings are summarized in the table below:
Source Name | Susceptibility Rating | SWAP Report Date |
CAPE FEAR RIVER | Moderate | 9/10/2020 |
DUNN/CAPE FEAR RIVER | Higher | 9/10/2020 |
The Complete SWAP Assessment report for Harnett Regional Water may be viewed on the website: https://www.ncwater.org/?page=600 . Note that because SWAP results and reports are periodically updated by the PWS section, the results may differ from the results on the CCR. To obtain a printed copy of this report, please mail a written request to: Source Water Assessment Program- Report Request. 1634 Mail Service Center, Raleigh NC 27699-1634, or email request to swap@deq.nc.gov. Please indicate System Name (Harnett Regional Water PWSID 03-43-045), and provide your name, mailing address, and phone number. If you have any questions about the SWAP report, please contact the Source Water Assessment Staff by phone at 919-707-9098.
It is important to understand that a susceptibility rating of "higher" does not imply poor water quality, only the systems' potential to become contaminated by PCS's in the assessment area.
Director's Corner
HRW experienced a very productive year in 2024. Harnett County continues to grow at an astounding pace with many new planned residential developments underway. HRW is very busy planning to accommodate this growth to ensure our ability to provide our customers with outstanding water and sewer service well into the future. All our existing residential and commercial water services now have new automated digital meters which do not require manual reading. All HRW customers have the ability to view and track water usage, receive notification of leaks, and learn tips to save money on their bills. This free service is part of our commitment to provide you with the bets tools to manage your water use and bill. We encourage you to get started today by logging in to the WaterSmart portal with your mobile device or web browser. You can log on at https://hrwnc.watersmart.com. There has been a lot of attention in the media lately concerning PFAS, which stands for per- and polyfluoroalkyl substances, which are a class of manmade chemicals present at low levels in most fresh water supplies, homes, offices, supermarkets-practically everywhere. These chemicals make consumer goods resistant to stains, grease, water, etc. and have been manufactured for use in our consumer goods for years. The problem lies in that they are impossible to avoid and are called "forever chemicals" because they are nearly indestructible. These chemicals have recently been found to pose risks to our health. The United States Environmental Protection Agency (EPA) in association with the North Carolina Department of Environmental Quality (NCDEQ) has tasked public water systems to develop ways to reduce those chemicals to a safe level. HRW has begun a pilot project to do just that and is working towards implementing additional methods to ensure that these chemicals will be safely removed from our water supply.
We are very proud of our record of environmental compliance as evidenced by this water quality report. We did not have any water quality violations and produced excellent water for our customers as always. Contact us by email or phone to get your water treatment questions answered. HRW is very fortunate to have such a fine group of water treatment professionals who strive daily to provide only the best drinking water to all of our citizens. HRW will continue to serve the citizens of Harnett County and the surrounding region by supplying only the best of the most important commodity in the world, water.
The Harnett County Regional Water Treatment Plant does voluntary quarterly monitoring of its source water for cryptosporidium. Cryptosporidium is a microbial parasite, which is found in surface water throughout the United States. Of the four quarterly tests, we only had a detect on the second quarter with 0.09 total (Oo)cysts/liter.
Additional Information
We routinely monitor for over 150 contaminants in your drinking water according to Federal and State laws. The following tables list the contaminants detected in the last round of sampling. The presence of contaminants does not necessarily indicate that water poses a health risk. Unless otherwise noted, the data presented in these tables are from testing done January 1 through December 31, 2024. The EPA and the State allow us to monitor for certain contaminants less than once per year because the concentrations of these contaminants are not expected to vary significantly from year to year. Some of the data, though representative of the water quality, is more than one year old. In these tables you will find many terms and abbreviations you may not be familiar with. To help you better understand these terms, we've provided the following definitions:
