Durham's 2025 Annual Drinking Water Quality Report identifies Lake Michie and Little River Reservoir as the city's surface-water sources. The system also purchased water from the Town of Cary during 2025. Durham operates the Williams and Brown water treatment plants before finished water enters the distribution system.
Have a private well instead of Durham municipal water? Well-water treatment starts with the conditions at your property. This North Carolina video explains how iron and sulfur are identified and why treatment order matters when more than one well-water problem is present.
How to Remove Iron or Sulfur From North Carolina Well Water
Read Transcript
How to remove sulfur or iron in North Carolina well water.
Guys, whether you're in Pasquotank County, across the Virginia line, Currituck County, we can keep going down the coast and come west. A lot of you are facing generally about the same thing in most well water. There are tannins and other things that you run into, and of course we could put out a long list.
This video is really targeting the sulfur and the iron, what to look for, and how to treat it. We'd always advise you, if you want a free consultation, give us a call. We can do a lot of things over the phone. Sometimes we do have to test in person to see whether this is oxidized iron, ferrous iron, or ferric iron.
Some of you guys, when you're moving into the home, they require you to have that well water test, and it's usually just a bacterial test. They don't care whether you can do a load of laundry or not. They just want to know if you have salmonella or E. coli. That's basically one of the main tests that you have to get done, even for refinances and things like that.
This video is just geared to point you in the right direction a little bit and to also give you a little bit of comfort that, as crazy as that water may seem, it may be coming out orange, all of it's treatable.
Water's water. It was at some point in a really nasty state whether you're on city water or well water. The city does a lot of the things that we're going to do here prior to them sending it through all the pipes and coming into people's homes.
With iron, there are two types: ferrous and ferric iron. You want to know whether or not this iron is oxidizing early or not, and then the level of iron. You can remove a little bit of iron, especially when you get into dissolved iron. Up to about two parts of iron is kind of a good number to be thinking about. I would stop trying to remove that with a water softener after that. It has to be dissolved iron.
We are the exclusive representative for over 25 to 27 Lowe's all the way down the coast, even getting west off the coast of North Carolina. We come behind people doing it themselves all the time. The associates, we love them in Lowe's and we love them in Home Depot and other places. They're doing their best with the knowledge they have, and sometimes they tell you, "Yeah, get this system here."
Especially for the sulfur, we were mainly talking about the iron to start off with, but that's a gas. You cannot take that out with a water softener. Yes, some things happen over the first two or three weeks, especially if you've got a carbon system or something. They'll help you for two or three weeks. Then you start to see those things get saturated, but that gas has to be oxidized out.
Back to the iron. If you're ever really over two parts of dissolved iron, I'd really be looking into an exclusive iron system. Behind me, you can see the Protector Series Iron Sulfur Breaker. It is a beast. It does oxidize and take out all of the iron, and we do a lifetime warranty on that equipment. It's a one-year labor warranty. Five years down the road, we couldn't stay in business if we couldn't get our labor covered if you had to have something done to it.
These machines will take out all the iron. Especially if you have any sulfur with that iron, we're straight going to that. It'll do both of those at the same time without using any salt.
It's not softening the water. That's a big difference. If we go back to taking out two parts or less of dissolved iron, you can do that with the water softener if it's not oxidized iron.
Again, we're only a phone call away. This doesn't have to be overwhelming, taking a bunch of crazy notes.
I will tell you, for the people that shop online and really go look at all the Chinese equipment on there that says Aqua this, H2O this, if their equipment was quality, they would have a dealer putting them in. As a water treatment company, I can just tell you, you can't stay in business if you're not using quality equipment because of the service costs when you have to honor those warranties and come back and come back and come back. Two or three calls and you took the profit out of your transaction already.
Using quality equipment is paramount when you're messing with iron. Iron ends up being like a tar or resin. It sticks to about everything it touches. Then it starts to accumulate on itself.
But ferric iron, if you have oxidized iron, let's just say that water's even slightly coming out orange, get water softener out of your vocabulary. You're going to have to go to an iron system that exclusively removes the iron before you ever run that into a water softener or anything else that you're going to try to filter out.
When you get into the iron, pH does need to be at least 6.0. One of the things, if you're chasing multiple problems, just know that you always have to take that iron out first. If you're chasing tannins, if you're chasing hardness, all of that equipment will be destroyed with iron if you don't remove it first.
In the spirit of trying to keep these videos short and sweet, we're going to close that out right there. Just keep in mind, with the sulfur, the Iron Sulfur Breaker here will take out all of that at one time. It doesn't use salt. In the most extreme circumstances, sometimes we have to upsize those.
We use these systems for irrigation as well. We'll go on these 20-foot irrigation wells in neighborhoods where they're staining their sidewalk, staining their house, and we'll use those systems to take that out as well.
Again, it's awesome because they don't use salt. I hope this video helps you guys out. Give us a call. Check out our videos. We have a ton of videos for all kinds of situations, especially with well water.
We try to make these videos educational, not blasting you with a product the entire time you're sitting here trying to learn something and having to close out screens and all that stuff.
Hope you enjoyed it. Any more questions, check us out or give us a call. Thanks.

What the 2025 Durham Water Report Shows
Durham reported 100% compliance with federal drinking-water standards in 2025 while routinely monitoring more than 150 contaminants. The same report also gives homeowners useful context about disinfectants, disinfection byproducts, lead and PFAS monitoring.
Chlorine & Chloramines
The 2025 report lists annual running averages of 0.63 ppm chlorine and 1.5 ppm chloramines, both reported without an MRDL violation.
- Chlorine range: 0.0–2.04 ppm
- Chloramine range: 0.01–3.0 ppm
- Used to control microbes in the distribution system
PFAS Were Detected in 2025
Durham's unregulated-contaminant table reports PFOA, PFOS, PFBS and PFBA in 2025 samples. The page dedicated to PFAS explains the results and treatment options in more detail.
- PFOA average: 3.8 ppt
- PFOS average: 5.6 ppt
- PFBS average: 5.9 ppt
Lead, TTHM & HAA5
The 2025 lead result was non-detect at the 90th percentile with zero sampled sites above the action level. TTHM and HAA5 were reported at 56 ppb and 49 ppb highest LRAA, respectively, with no MCL violations.
- Lead 90th percentile: non-detect
- TTHM MCL: 80 ppb
- HAA5 MCL: 60 ppb
Well Water Needs Property-Specific Testing
Durham's municipal Water Quality Report describes the public water system, not private wells. Well-water conditions can vary from one property to the next, so treatment should be based on the water actually entering that home.
Iron staining, rotten-egg sulfur odor, acidity, tannins, sediment and hardness are separate conditions and may require different treatment methods or treatment order.
Municipal results do not predict private-well water.
A citywide report can tell you about Durham's public system, but it cannot determine the chemistry, bacteria status or mineral content of an individual private well.

Durham Water Treatment Questions
Where does Durham drinking water come from?
Durham's 2025 Annual Drinking Water Quality Report identifies Lake Michie and Little River Reservoir as the city's surface-water sources. The system also purchased water from the Town of Cary during 2025.
Did Durham meet drinking-water standards in 2025?
Yes. Durham reported 100% compliance with federal drinking-water quality standards for 2025 and no violations covering the January 1 through December 31, 2025 reporting period.
Were PFAS detected in Durham water?
Yes. Durham's 2025 report lists PFOA, PFOS, PFBS and PFBA in its unregulated-contaminant monitoring results. Those detections should be considered separately from the report's regulated compliance tables.
Does Durham use chlorine or chloramines?
The 2025 report lists both chlorine and chloramines in its disinfectant residual summary, with annual running averages of 0.63 ppm chlorine and 1.5 ppm chloramines.
What does ECWQ's free water test check?
The in-home evaluation can check common household water characteristics such as hardness, disinfectant residual and pH. It is not a certified laboratory analysis for PFAS, lead, arsenic, bacteria or nitrate.
Do you treat private well water around Durham?
Yes. Private-well treatment should be based on property-specific conditions because municipal testing does not describe an individual well. Iron, sulfur odor, acidity, tannins, sediment and hardness can require different treatment approaches.
