Burlington NC Water Problems, Contaminants & Treatment Options
See what Burlington's 2025 drinking-water report and EWG data show, understand how PFAS, disinfection byproducts, hardness and household plumbing fit together, and compare treatment options for the concern you want to address at home.
What Should Burlington Homeowners Know About Their Tap Water?
Burlington's 2025 Consumer Confidence Report provides the city's current regulatory picture for its public water system. It also shows measurable PFAS in both finished-water plants, disinfection byproducts, a December 2025 monitoring violation, and low reported hardness. EWG uses a different set of non-enforceable health guidelines and lists 14 contaminants above those benchmarks.
For drinking and cooking water: reverse osmosis is often the first system category to compare when the goal is broad reduction of dissolved contaminants at a dedicated faucet.
For whole-home disinfectant taste or odor: compare a conditioner or carbon-based whole-home system configured for Burlington's chloramine-treated municipal water.
For PFAS or lead concerns: compare targeted PFAS/lead filtration with reverse osmosis and confirm performance for the exact model selected.
For a private well: do not use Burlington's municipal-water numbers to choose treatment. Well water requires property-specific testing for iron, sulfur, pH, tannins, sediment and other conditions.
Not Sure What These Water Results Mean for Your Home?
City and EWG data describe the public water system, but your plumbing, water source and treatment goals are specific to your home. Schedule a thorough in-home water evaluation and have a local technician test your household water sources, explain the findings and recommend next steps.
The in-home evaluation is not an extensive certified laboratory analysis. PFAS, lead, arsenic, nitrate, bacteria and similar contaminants require appropriate laboratory testing.
Start With Where You Want the Water Treated
The most useful first decision is whether you want highly filtered water at the kitchen sink, treatment throughout the home, targeted PFAS and lead filtration, or a property-specific private-well solution.
Drinking and Cooking Water
Choose reverse osmosis when the main goal is reducing a broad range of dissolved contaminants at a dedicated faucet and, where practical, a refrigerator line.
Explore Burlington Reverse Osmosis →Whole-Home Conditioning and Carbon Treatment
Choose whole-home treatment when the main concerns are chlorine or chloramine, taste and odor, or when property-specific testing and household goals support softening or conditioning.
Explore Burlington Water Conditioners →Targeted PFAS and Lead Filtration
Choose the PFAS / Lead category when the goal is specialized whole-home treatment for specified PFAS and lead concerns, often paired with RO drinking water.
Explore Burlington PFAS Filters →Private-Well Conditions
Choose well-water treatment for iron, sulfur odor, low pH, tannins, sediment or other property-specific conditions identified through appropriate testing.
Explore Burlington Well Water Treatment →What Is Reported in Burlington Drinking Water?
Burlington's 2025 Annual Drinking Water Quality Report covers calendar-year 2025 monitoring for a surface-water system supplied by Lake Mackintosh and Stoney Creek Reservoir. The city treats that water at the J.D. Mackintosh, Jr. and Ed Thomas water treatment plants. EWG separately summarizes utility data from 2014–2023 and applies independent health-based benchmarks.
Regulatory Standards
Burlington's official report lists maximum contaminant levels, action levels, treatment techniques and monitoring requirements used for regulatory compliance.
Health Guidelines
EWG health guidelines are non-enforceable benchmarks. A substance can be within a federal legal limit while still appearing above an EWG guideline.
Your Home
City-wide monitoring cannot describe every service line, fixture or plumbing condition. It also does not describe private-well water outside the municipal system.
Legal standards and EWG guidelines are different measurements of risk.
Use Burlington's official report for regulatory compliance information. EWG's values provide separate health-guideline context and can use different sampling periods, so the two datasets should not be treated as if they were the same test.
Contaminants Shown Above EWG Health Guidelines
EWG's City of Burlington utility page lists 14 contaminants above its health guidelines and 25 total contaminants. Its utility data covers 2014–2023, while some PFAS comparison values use monitoring through 2024. These EWG benchmarks are not federal drinking-water compliance limits.
For PFOS and PFOA, the 4 ppt federal MCLs have been finalized; Burlington's 2025 city report states that public water systems must comply with the PFAS MCLs beginning in April 2029. The EWG utility figures above come from EWG's own reporting periods and should not be substituted for Burlington's 2025 plant-specific PFAS results.
Other Contaminants Detected in Burlington Water
EWG also lists 11 other detected contaminants for Burlington that are not in its “above health guidelines” group. The values below preserve EWG's utility averages and the guideline or legal-limit context shown on its Burlington utility page.
Contaminants and Water Characteristics in Burlington's Official Report
Burlington's 2025 Annual Drinking Water Quality Report summarizes monitoring from calendar year 2025, with older sampling dates identified where required. The report's compliance tables and the EWG database use different datasets and should be read separately.
| Substance or Measure | Official Report Result | Standard or Context | Why Homeowners May Care |
|---|---|---|---|
| Disinfection and byproducts | |||
| Chlorine | 1.51 ppm running annual average; range 0.34–2.3 ppm | MRDL 4.0 ppm; no violation reported | Burlington uses disinfectant residuals to control microbes. |
| Chloramine | 2.31 ppm running annual average; range 1.0–3.98 ppm | MRDL 4.0 ppm; no violation reported | Burlington uses chloramine as a secondary disinfectant in the distribution system. |
| Total trihalomethanes (TTHM) | 51 ppb LRAA shown at B05; range 27–62 ppb | MCL 80 ppb; no violation reported | Disinfection byproducts; treatment choice depends on whether the goal is drinking-water or whole-home reduction. |
| Haloacetic acids (HAA5) | 48 ppb LRAA shown at B05; range 16–46 ppb | MCL 60 ppb; no violation reported | Disinfection byproducts formed during treatment. |
| Inorganic compounds and household characteristics | |||
| Barium | <0.4 mg/L at both plants | MCL 2 mg/L; no violation reported | A dissolved inorganic contaminant included in routine monitoring. |
| Fluoride | 0.73 mg/L at JDMWTP; 0.65 mg/L at ETWTP | MCL 4 mg/L; no violation reported | Some homeowners compare RO when they want lower fluoride in drinking water. |
| Nitrate | <1.0 mg/L at both plants | MCL 10 mg/L; no violation reported | Nitrate requires appropriate laboratory testing when a property-specific result is needed. |
| Hardness | 28.5 mg/L (1.67 gpg) JDMWTP; 27.4 mg/L (1.60 gpg) ETWTP | Informational, not a health-based MCL | The city report shows low finished-water hardness, so Burlington should not be presented as having severe municipal hard water. |
| pH | 8.0 at both plants | System-average operational information | Useful context when evaluating the water entering the distribution system. |
| Lead, copper and monitoring | |||
| Lead | 90th percentile <3 ppb; 1 site above the action level | Action level 15 ppb | Lead can vary with service-line and household plumbing conditions. |
| Copper | 90th percentile 0.125 mg/L; 0 sites above the action level | Action level 1.3 mg/L | Copper can also be influenced by plumbing corrosion. |
| December 2025 monitoring | 67 of 70 required Total Coliform and Disinfection Residual samples collected | Monitoring violation reported | The city says three additional samples were recommended for January 2026 to address the missed samples. |
Use Burlington's official Consumer Confidence Report for compliance information. EWG's health-guideline figures use separate data and reporting periods.
Why Can Burlington Water Taste or Smell Different From Home to Home?
Burlington's report describes the public supply, but what you notice at the faucet can also be affected by chloramine, plumbing materials, water age inside a building and any treatment already installed at the property.
Chloramine and Disinfectant Taste
Burlington has used chloramine as its secondary distribution-system disinfectant since 2011. Homeowners who want whole-home reduction of disinfectant taste or odor can compare treatment configured specifically for chloramine.
Low Reported Hardness
The 2025 report lists finished-water hardness of 1.67 grains per gallon at J.D. Mackintosh and 1.60 grains per gallon at Ed Thomas. That is useful context before assuming a softener is needed for Burlington city water.
Household Plumbing
Service lines, fixtures and internal plumbing can affect the water at an individual faucet. A city-wide report cannot determine every property-specific condition.
Burlington's Latest Report Gives These Concerns Different Context
Burlington's 2025 report includes plant-specific PFAS monitoring and lead/copper sampling, but PFAS in finished municipal water and lead associated with service lines or household plumbing are not the same problem.
PFAS Monitoring in Burlington
In three 2025 rounds, the city reports average PFOA of 3.3 ppt at J.D. Mackintosh and 5.1 ppt at Ed Thomas. Average PFOS was 4.3 ppt and 4.2 ppt, respectively. The report lists 4.0 ppt MCLs for PFOA and PFOS and states that public-water-system compliance begins in April 2029.
The same table reports PFHxS averages of 1.1 and 0.6 ppt, PFNA averages of 0.1 and 0.0 ppt, and GenX at 0.0 ppt at both plants.
Lead Can Be Property-Specific
The city's 2024 lead sampling, reported in the 2025 CCR, shows a 90th-percentile result below 3 ppb and one sampled site above the 15 ppb action level.
Burlington's service-line inventory separately lists 0 lead service lines, 84 galvanized lines requiring replacement, 24,418 non-lead lines and 612 unknown lines. Plumbing inside the home can still affect a faucet-level result.
Use certified laboratory testing when you need a contaminant-specific answer.
ECWQ's in-home evaluation is useful for common household water conditions and treatment planning. PFAS, lead, arsenic, nitrate, bacteria and many other specific contaminants require appropriate laboratory testing.
Which Burlington Water Treatment System Addresses Which Problem?
No single system is the best choice for every water concern. The correct treatment depends on the substance, whether you want to treat one drinking-water faucet or the whole home, and the exact performance claims of the selected model.
Read this matrix as a treatment guide—not a blanket removal guarantee.
Actual reduction depends on system configuration, media, membrane performance, flow rate, maintenance, water chemistry and certification. Confirm performance against the exact product specifications for the system you are considering.

Not sure which page matches your concern?
Start with whether the problem affects only drinking water, every fixture in the home, a specific contaminant such as PFAS or lead, or a private-well condition. ECWQ can then help determine which system category deserves a closer look.
Use the Right Test for the Right Water Problem
A home water evaluation can identify common aesthetic conditions, but many health-related contaminants require specialized laboratory testing and careful sample collection.
Free In-Home Water Test
A thorough technician-led in-home evaluation that compares household water sources, explains the results in plain English and helps determine which treatment category may fit the home. It is not an extensive certified laboratory contaminant analysis.
Certified Laboratory Testing
PFAS, lead, arsenic, nitrate, bacteria and other specific contaminants may require certified laboratory testing using the correct sampling method.
Private-Well Testing
Well-water treatment should be based on the conditions at the property. Iron, sulfur, pH, tannins, sediment and bacteria can vary significantly from one well to another.

Burlington NC Water Problems FAQs
Where does Burlington's city water come from?
Burlington uses two surface-water supplies. Lake Mackintosh supplies the J.D. Mackintosh, Jr. Water Treatment Plant, and Stoney Creek Reservoir supplies the Ed Thomas Water Treatment Plant.
Does Burlington use chloramine?
Yes. Burlington has used chloramine as its secondary disinfectant in the distribution system since July 2011. The 2025 report lists a chloramine running annual average of 2.31 ppm and no disinfectant-residual violation in that table.
Is Burlington city water hard?
The 2025 report lists 28.5 mg/L, or 1.67 grains per gallon, at the J.D. Mackintosh plant and 27.4 mg/L, or 1.60 grains per gallon, at the Ed Thomas plant. Those figures do not support describing Burlington municipal water as severely hard.
What does EWG show above its health guidelines in Burlington?
EWG lists 14 contaminants above its health guidelines, including several disinfection byproducts, hexavalent chromium and multiple PFAS. EWG health guidelines are not enforceable federal drinking-water standards and use reporting periods that differ from Burlington's 2025 city report.
Were PFAS reported in Burlington's 2025 drinking-water data?
Yes. Burlington's 2025 additional monitoring reports measurable PFOA, PFOS and PFHxS at both treatment plants, with PFNA also reported at J.D. Mackintosh. GenX is reported at 0.0 ppt at both plants in that table.
Did Burlington have a drinking-water violation in 2025?
The city reports a December 2025 monitoring violation because 67 of 70 required Total Coliform and Disinfection Residual samples were collected. The report says three additional samples were recommended in January 2026 to address the missed monitoring.
Can lead vary from one Burlington home to another?
Yes. Burlington's report explains that lead in drinking water is primarily associated with service lines and household plumbing components. System-wide monitoring cannot determine the lead concentration at every individual faucet.
Would reverse osmosis help with Burlington water concerns?
Reverse osmosis is commonly considered for point-of-use drinking-water goals involving dissolved contaminants. The appropriate system depends on the target contaminant and the documented performance of the exact model.
Do I need a water conditioner on Burlington city water?
The city's reported hardness is low, so a conditioner should not be recommended simply by assuming severe hardness. A whole-home system may still be considered for a specific chloramine, taste, odor or household conditioning goal when the equipment is configured for that purpose.
Do Burlington city-water results apply to a private well?
No. The municipal report describes Burlington's public surface-water system. Private wells can have different iron, sulfur, pH, tannin, sediment, bacteria and hardness conditions and should be evaluated using property-specific testing.
