Hickory Water Quality Guide: City Water, Wells and Filters (2026)

Where does Hickory's water come from?

The City of Hickory's water treatment facility draws from the Catawba River. According to the city's Public Utilities facilities page, two Duke Power dams, Rhodhiss and Oxford, create a deep-water reservoir where the intake sits.

The same page says the plant has a rated capacity of 32 million gallons per day and runs around the clock. It serves customers in three counties. It also oversees three purchased water systems, covering areas from Icard to Claremont and from northern Alexander County to the Town of Catawba and Sherrills Ford. The towns of Maiden and Long View are supplied by Hickory as well.

That means your address matters. A home in Claremont or Sherrills Ford may be on Hickory-supplied water, a different municipal system, or a private well. Your water bill, or your utility's service map, is the quickest way to find out.

How is Hickory's water treated and disinfected?

The city describes its plant as a conventional surface water treatment facility. In general, that means the water goes through coagulation, settling and filtration before disinfection. The city page does not name the disinfectant or say whether fluoride is added, so check the annual report for those details instead of assuming.

The plant has been recognized by the state. The North Carolina Division of Water Resources gave it an Area Wide Optimization Program award for 2023, which the city's announcement says reflects strong turbidity removal. Turbidity is cloudiness from suspended particles, and keeping it low helps disinfection work.

Chlorine-based disinfectants are standard for surface water systems and can cause a pool-like smell or taste. If that bothers you, a carbon filter certified to NSF/ANSI 42 is the usual fix. If your utility uses chloramine, the approach is different, so confirm which disinfectant applies to you before buying anything.

How do I read Hickory's annual water quality report?

Every community water system must give customers an annual Consumer Confidence Report (CCR). Hickory posts its reports on the city's Public Utilities annual reports page. That page also lists a wastewater report, which is not the one you want, so make sure you open the drinking water report.

1. Open the report and find the source water section. It should name the Catawba River and may include a state source water assessment rating.
2. Go to the detected contaminants table. Compare each "level detected" against the "MCL" (the legal limit). Anything under the MCL meets the standard.
3. Look for disinfectant and disinfection byproduct rows (chlorine or chloramine, TTHM, HAA5). These tell you what the utility adds and what forms as a result.
4. Check the lead and copper rows. These come from samples at customer taps, not from the plant.
5. Look for a PFAS section or rows. EPA's rule requires utilities to complete initial PFAS monitoring by 2027, so some reports may not carry results yet.
6. Look for hardness or mineral rows. Some reports list them and some do not. If yours does not, call the utility at (828) 323-7400 and ask.

Not sure which number matters? You can also request a free local water report to go with the city's data.

Why do some Hickory homeowners still filter their water?

Meeting the legal standard does not mean the water suits every household. Common reasons people add treatment in the Hickory area:

• Taste and odor. Disinfectant taste, and seasonal earthy or musty notes that can occur in any river-fed supply.
• Older plumbing. Lead and copper come from pipes and fixtures inside or at the home, not from the plant.
• PFAS concerns. EPA has set limits for certain PFAS, and many households want an extra layer while the rules phase in.
• Infants or immune concerns. Parents sometimes want a certified point-of-use filter for formula and drinking water.
• Private wells. Here treatment is often needed for iron, manganese or other natural minerals, covered below.

For help deciding between systems, see our guide on whether you need a whole-house water filter.

What about PFAS in Hickory-area water?

PFAS are a family of man-made chemicals. In April 2024 EPA set enforceable limits for six PFAS, including 4.0 parts per trillion each for PFOA and PFOS. According to EPA's PFAS page, updated May 18, 2026, EPA has proposed extending the PFOA and PFOS compliance date and rescinding the limits for the other PFAS. Neither proposal is final.

We did not find a Hickory-specific PFAS result we could verify, so we are not stating one. Look for PFAS rows in the city's current report, or ask the utility directly. Catawba County also links PFAS testing and filtration instructions for well owners from its wells page.

For background, read our overview of PFAS in drinking water. It is written for Charlotte, but the science and filter standards apply here too.

Does older plumbing change the picture?

It can. According to EPA, lead is more likely in homes built before 1986, and lead service lines are usually the biggest source where they exist. Without a lead line, brass fixtures and lead solder are the usual suspects.

We did not find a published count of lead service lines for Hickory, so we do not cite one. To find out about your own home, ask the utility, or have a licensed plumber look at the pipe where it enters the house.

• Use cold water for drinking, cooking and baby formula. Boiling does not remove lead.
• Run the tap before use if water has been sitting for hours.
• Clean faucet aerators regularly.
• If you filter for lead, choose a product certified for lead removal and replace cartridges on schedule.

What is in Catawba County well water?

Many homes outside city and town limits in Catawba County, and across the foothills, rely on private wells. The state's Catawba County well data table summarizes private well samples. The table does not give collection dates or explain how wells were selected, so treat it as a general picture, not a promise about any one well.

Secondary standards cover taste, odor, color and staining, not health limits. Iron and manganese cause orange or black staining and a metallic taste. Lead and arsenic have enforceable limits, and even a small share of wells above them is a reason to test.

The county notes that drilled wells may have high iron, manganese, magnesium or calcium, which can be removed only by filtration. Our well water filtration guide walks through typical equipment, and the filter versus softener comparison explains which one handles hardness.

Should well owners test for radon and bacteria?

Yes, they are the two tests most often skipped. The state's radionuclides fact sheet says radionuclides occur naturally in rock and soil and can move into groundwater. It suggests starting with gross alpha, gross beta, uranium and radon, and adding radium if concerns persist. It also says the NC Radiation Protection Section recommends testing all homes for radon in air, well or not.

The state data table we cite above does not include radon or bacteria figures, so we are not giving local percentages for either.

Bacteria cannot be seen, tasted or smelled. Catawba County Environmental Health collects well samples Monday through Thursday through its ePermitting system and says bacteriological results take 4 to 5 days, with chemical results taking 3 to 4 weeks. Its page says not to use a well that has been flooded or submerged. After a storm, follow the guidance from NC DHHS and your health department.

Which Hickory-area situation sounds like yours?

Use this list to find a starting point. It is general guidance, not a diagnosis.

• If you are on Hickory city water and just dislike the taste, start with a carbon filter certified to NSF/ANSI 42 at one tap.
• If you are on city water and your home was built before 1986, ask about the service line and test for lead at the tap.
• If you are on city water and worried about PFAS, check the current report, then consider a point-of-use filter certified to NSF/ANSI 53 or 58 for PFOA/PFOS (look for a PFAS reduction claim on the certification listing).
• If you have a private well, test for bacteria, iron, manganese, lead, arsenic and radon first, then pick equipment to match the results.
• If your well water stains fixtures orange or black, get a mineral test before buying a system, since the right choice depends on the form of iron and your pH.
• If you are in Claremont, Catawba, Sherrills Ford, Maiden or Long View, confirm who your water supplier is before reading a report.
• If your well was flooded, stop drinking from it until it is disinfected and retested.

What about Newton, Conover, Morganton and Lenoir?

Water suppliers differ across the metro area, so a report for one town may not describe yours. We could not verify supplier details for Newton, Conover or Lenoir from primary sources, so check your own bill and your supplier's current report.

Morganton's water plant draws from the Catawba River and averages 8.8 million gallons of potable water per day, according to the city's Water Resources page. Its reports are posted on the Morganton water quality reports page.

Homes just outside any town service area often fall back to wells, so the Catawba County data above may apply to you even with a Hickory mailing address.

When should I test my water?

• You have a private well and have never tested it, or it has been several years.
• After flooding, a nearby construction project, or well or pump repairs.
• Water changes in color, taste, odor or clarity.
• You are buying a home, or a baby or pregnancy is in the household.
• You have older plumbing or know you have a lead service line.
• Before buying any treatment equipment.

Use a lab certified by the NC State Laboratory of Public Health, or Catawba County Environmental Health. A certified lab report beats a home test strip for any decision involving money or health.

Which treatment fits which concern?

For ballpark pricing, see our whole-house filter cost guide. The state's radionuclide fact sheet puts installed treatment for radionuclides at roughly $1,000 to $15,000, depending on the contaminant and system.

What should I ask a water treatment installer?

1. Which lab test will you base the recommendation on, and can I see the report?
2. Which NSF/ANSI standard is the product certified to, and for which contaminant claims?
3. What does yearly maintenance cost, and how often do filters or media change?
4. How much water does it waste, and does it need a drain or electricity?
5. Is the quote for the specific problem in my test results, not a standard package?
6. What is the warranty, and who services it?
7. Will you retest after installation to confirm it works?
