Where Wilmington’s CFPUA Water Comes From

The CFPUA-Wilmington Water System uses both surface water and groundwater. The Sweeney Water Treatment Plant draws from the Cape Fear River, while the Richardson Water Treatment Plant uses groundwater from the Castle Hayne and PeeDee aquifers. The 2025 report also includes groundwater sources that were integrated from the former Monterey Heights system.

What the 2025 Report Shows

Wilmington Water Has a Mixed Surface-Water and Groundwater Profile

CFPUA reported that its drinking water met federal and North Carolina regulatory standards in 2025. For the CFPUA-Wilmington system, hardness averaged 50 ppm and ranged from 39 to 62 ppm. Reported pH ranged from 7.3 to 7.5.

The report also lists chlorine as the distribution disinfectant, with a 2025 running annual average of 1.16 ppm. TTHM and HAA5 results were reported below their federal maximum contaminant levels. Separate 2025 monitoring also reported a number of PFAS compounds, with results varying by compound and source.

EWG guidelines are not the same as legal drinking-water limits.

EWG currently lists 22 contaminants above its health guidelines for the CFPUA-Wilmington utility, while also noting that the utility was in compliance with federal health-based drinking-water standards for the latest EPA quarter shown in its database. The two benchmarks should be read separately.

Private Well Water

Iron and Sulfur Need a Different Treatment Approach

Private-well water is separate from CFPUA municipal water and should be evaluated at the property. This North Carolina well-water video explains the difference between dissolved and oxidized iron, why sulfur odor needs oxidation, and why iron treatment may need to come before other equipment.

How to remove sulfur or iron in North Carolina well water

How to remove my sulfur or my iron in my 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.

Frequently Asked Questions

Wilmington Water Treatment Questions

Where does Wilmington, NC municipal water come from?

The CFPUA-Wilmington Water System uses water from the Cape Fear River and groundwater sources. Sweeney Water Treatment Plant treats Cape Fear River water, while Richardson Water Treatment Plant treats groundwater from the Castle Hayne and PeeDee aquifers.

How hard is Wilmington municipal water?

CFPUA’s 2025 report lists hardness for the Wilmington system at an average of 50 ppm, with a range of 39 to 62 ppm. That is roughly 2.3 to 3.6 grains per gallon across the reported range.

Were PFAS detected in Wilmington water in 2025?

Yes. CFPUA’s 2025 report lists detections for multiple PFAS compounds in samples associated with the Sweeney and Richardson treatment plants and former Monterey Heights wells, with averages and ranges reported separately by compound. The detailed water-quality page explains those results without treating every PFAS value as the same type of benchmark.

Does CFPUA use chlorine?

Yes. The 2025 report lists chlorine with a running annual average of 1.16 ppm for the CFPUA-Wilmington system. CFPUA also describes UV and ozone as part of treatment at Sweeney before water enters distribution.

Is private well water the same as Wilmington city water?

No. A private well is not represented by CFPUA’s municipal Water Quality Report. Well-water conditions can vary by property, so iron, sulfur, pH, tannins, hardness and other concerns should be evaluated for the individual well.

What does ECWQ’s free in-home water test check?

The in-home evaluation can check common water conditions such as hardness, chlorine and pH and compare household water sources. It is not a certified laboratory analysis for contaminants such as PFAS, lead, bacteria or nitrate.
