Here is my deep dive into water quality for Johns Creek, which is in Fulton County, GA. It is Fulton County who provides the public water.
I can't stand the smell of the Fulton County water coming out of our faucet, most especially in the morning. I try my best to stay away from it, at least drinking it. I am financially conservative and economical, so we've been considering other options to avoid the purchase of bottled water and improve the water quality in our hose.
My wife and I have been drinking "around" this problem for years. She has been an avid consumer and drinker of Evian Water, which she got me hooked on. It does taste great. However, our projected consumption and cost of Evian
1 case of 12-bottles of Evian = $20.99 (or less at times)
3 cases ordered and delivered per week = $62.97 per week
Multipied by 50 weeks in a year (assuming we are gone for at least 2-weeks) = $3,148.50 per year
That is alot of money spent trying to "be healthy", but again... we are still drinking it (via coffee), showering or bathing in it (seeps into our pores), and cooking with it (though boiling gets rid of bacteria), but not other things like chemicals, heavy metals, etc... So, I question just exactly what the quality is and how much of the bad stuff is getting into our bodies one way or another.
So, she asked me to investigate this with our plumber, but he's not an expert in water quality. He controls what water comes in and goes out only. I considering finding a lab to test the water, which is not a bad idea.
However, I decided on using A.I. instead and in my case, ChatGPT. I have my ChatGPT customized to "me"... and I like verifiable deep-dive data that can be proved and cited by source. Often, I still need to check it but it does a lot of the leg work that I'd do anyway... and quicker.
So, here are my queries or instructions to ChatGPT in red. If you know A.I., the secret sauce or part of it is in the instructions you give it, which those are in red (as our my comments.) It's findings are in black.
Do a deep dive into water purifications systems for residential use. We live in Johns Creek, GA 30022 (Fulton County, GA) and we'd like a system that addresses our water needs particularly to our area. Among likely other things, we find the water to be heavy chlorinated - at least by smell, but we'd like to address and improve our water quality in this area.
Got it. Let’s tailor a home system for Johns Creek (30022, Fulton County)—no fluff.
What you’re actually drinking (locally)
Source: Chattahoochee River, treated at the Tom Lowe Atlanta–Fulton County Water Treatment Plant in Johns Creek.
Disinfectant: Free chlorine (that is what we smell heavily in the morning) (it is not chloramine). The 2024 monitoring shows a chlorine residual up to ~2.19 ppmin the distribution system (range 0.01–2.19 ppm). If you smell it, you’re not imagining things.
Disinfection byproducts:
TTHMs (trihalomethanes) highest locational running annual average: 67.4 ppb (MCL = 80 ppb). Range 23.7–83.1 ppb.
HAA5 (haloacetic acids) highest locational running annual average: 36.3 ppb (MCL = 60 ppb). Range 21.0–42.0 ppb.
Lead/Copper at taps: 2024 sampling cycle—0 of 50 sites above action levels; 90th-percentile lead 1.6 µg/L, copper 130 µg/L (both well below action levels). Still can vary house-to-house with plumbing.
PFAS: New EPA MCLs (e.g., 4 ppt PFOA/PFOS). Systems have until 2027 for initial monitoring; GA EPD is coordinating statewide. Treatability at home: RO, GAC, or ion-exchange can reduce PFAS when properly maintained. (Environmental Protection Division, US EPA)
What that means for treatment goals
(Johns Creek–specific)
Knock down chlorine taste/odor throughout the house.
Reduce TTHMs/HAA5 (chlorine byproducts).
Point-of-use “polish” for drinking/cooking: catch PFAS, trace metals, and misc. organics.
Keep maintenance sane. ROI matters.
The setup I’d install in your shoes
Whole-home (Point-of-Entry, POE)
Sediment prefilter (5–20 μm) – protects the carbon bed, cheap to maintain (6–12 mo).
Backwashing catalytic carbon tank (not a tiny cartridge):
Why: Catalytic/activated carbon is proven to reduce chlorine (NSF/ANSI 42) and can significantly reduce TTHMs/HAA5 when sized correctly (empty-bed contact time, bed depth). (NSF, SimpleLab Tap Score)
What to look for:
POE tank (e.g., 10×54" or 12×52"), 1.0–2.0 ft³ of catalytic carbon, automatic backwash valve, service flow matched to your home’s peak GPM (showers + appliances).
Certifications: NSF/ANSI 42 for chlorine/taste/odor. If the vendor claims DBP reduction, ask for data at your flow rate. (NSF)
(Optional) KDF-55 media blend in the POE to help with chlorine and extend carbon life (nice-to-have, not mandatory).
Why not a softener by default? Fulton’s CCR doesn’t publish hardness, and Chattahoochee water is usually not very hard. Softener = salt, drain, maintenance—only add it after a hardness test confirms scaling. (We can test first.)
Drinking water (Point-of-Use, POU)
Under-sink Reverse Osmosis (RO) with remineralization at the kitchen sink (and fridge if you like):
Why: RO + carbon is the most practical way to reduce PFAS, plus many dissolved inorganics and trace contaminants; it also improves taste. Look for NSF/ANSI 58 (RO performance), 53 (health contaminants), and 401 (emerging contaminants) claims as applicable. (US EPA, NSF)
Reality check: RO wastes some water; modern units are better (2:1 to 1:1). Worth it for the drinking line.
Showerheads? If chlorine smell bugs you in the shower, a POE carbon tank will already help. If not doing POE, use an NSF 42 shower filter (replace often).
UV? Not for you.
You’re on a well-run municipal plant; UV is overkill unless you have special medical concerns or recurrent boil-water notices (you don’t). POE carbon + POU RO is plenty here. (Chlorine residual already handles microbes.)
Sizing, upkeep, and ballpark costs (so no one oversells you)
POE sediment filter: $30–$60/yr in cartridges; swap 6–12 mo.
POE backwashing catalytic carbon: $1,500–$3,000 DIY tank; $3,000–$5,000 installed; media life ~5–7 yrsdepending on water use and DBP/chlorine load. Backwash every 4–7 days.
POU RO (under-sink): $300–$800 DIY; $700–$1,500 installed. Prefilters/postfilters 6–12 mo, membrane 2–5 yrs.
Annual operating: commonly $150–$350 for filters + a media top-off every few years (plan on $400–$800 when due). (Your usage will swing this.)
How we know this addresses your local issues
Chlorine odor/taste → NSF 42 carbon at POE. Your residuals can hit ~2.19 ppm—carbon knocks that down. (NSF)
TTHMs/HAA5 near mid-to-upper ranges (but within MCL) → Properly sized catalytic GAC at POE reduces precursors/byproducts; RO at POU further reduces what remains at the tap. (SimpleLab Tap Score)
PFAS risk posture → EPA confirms GAC/IX/RO at POU can greatly reduce PFAS; new 2024 NPDWR limits are strict (4 ppt). RO + carbon is the practical home combo. (US EPA, Environmental Protection Division)
What to buy (spec, not brand)
When you shop, insist on:
POE carbon tank: catalytic GAC, automatic backwash valve, spec sheet showing EBCT ≥ 5–10 minutes at your peak flow (installer can size; most 4–5-person homes land around a 10×54 or 12×52 tank).
Certifications:
NSF/ANSI 42 (chlorine) for the POE unit,
NSF/ANSI 58 (for RO), and—if claimed—53/401 for specific contaminants. (NSF)
Optional pre-purchase testing (targeted, not a science fair)
You’re on a regulated system, so you don’t need a thousand-dollar panel. But to fine-tune and validate:
At-tap free chlorine (cheap field kit).
Hardness, alkalinity, pH, TDS (guides softener decision).
Lead (first-draw) if the home predates 1986 fixtures/solder. Use a GA-certified lab. (US EPA, Environmental Protection Division)
PFAS screen (one time) via a GA-certified PFAS lab (EPA Methods 533/537.1). (Environmental Protection Division)
If you want, I’ll give you a minimalist test shortlist with exact lab names in metro Atlanta (so you’re not paying tourist prices).
Implementation plan (clean + fast)
Confirm peak flow (number of simultaneous showers/appliances).
Install POE sediment + backwashing catalytic carbon sized for your flow.
Install POU RO at kitchen (optional line to fridge).
Set calendar: sediment 6–12 mo; RO filters 6–12 mo; RO membrane 2–5 yrs; carbon media 5–7 yrs; backwash schedule locked in.
Post-install check: retest chlorine at tap and (optionally) PFAS via a certified lab to document ROI. (Environmental Protection Division, US EPA)
Local references & reading

If you want me to spec exact tank size and EBCT, tell me: number of bathrooms, max simultaneous showers, and whether you’re feeding irrigation from the same line. I’ll turn that into a parts list and a pro-level install diagram you can hand to a plumber—or install yourself if you’re feeling spicy.
We'd like that system to address the entire incoming water supply into this house. We have a 5-bedroom house with 5 bathrooms. With typically only 3 bathroom showers that can run at the same time.
Perfect—that helps size this system properly. For a 5-bedroom, 5-bath house in Johns Creek with up to 3 showers running simultaneously, here’s how to design a whole-house purification setup that won’t choke your water pressure:
1. Flow Rate & Sizing Basics
A typical shower = 2.0–2.5 GPM.
Three showers = ~6–7.5 GPM.
Add a buffer for toilets/dishwasher/washing machine = ~10 GPM peak demand.
So your whole-house (POE) filtration needs to reliably handle 10 GPM service flow without pressure drop.
2. Recommended System Design
Stage 1 – Sediment Pre-Filter
20" Big Blue sediment cartridge (5–10 micron).
Protects carbon tank from clogging with silt, rust, or sand.
Swap cartridge every 6–12 months.
Stage 2 – Backwashing Catalytic Carbon Tank
Media: Catalytic GAC (Granular Activated Carbon).
Tank Size: At least 2.0 cubic feet (e.g., 12×52" tank with Fleck or Clack automatic backwash valve).
Capacity: Service flow up to ~10–12 GPM → matches your household demand.
Function: Removes chlorine smell/taste, reduces disinfection byproducts (TTHMs/HAA5), improves overall water quality.
Maintenance: Backwash every 3–4 days; carbon replaced every 5–7 years.
Optional: Add KDF-55 media (extends carbon life, helps with chlorine and heavy metals).
Stage 3 – Drinking Water Polish (Point-of-Use)
At the kitchen sink (and optional fridge line):
Reverse Osmosis (RO) System
Reduces PFAS, trace metals, fluoride, nitrates, and anything carbon misses.
NSF/ANSI 58 certified.
Add remineralization filter so water isn’t flat/acidic.
Filters: pre/post every 6–12 months, membrane every 2–5 years.
Optional – Water Softener
Fulton County water isn’t particularly hard, but test first.
If hardness > 7 gpg, consider a salt-based softener AFTER the carbon tank (or use a template-assist anti-scale device if you want no-salt).
Benefits: protects fixtures, reduces soap usage, extends appliance life.
3. Maintenance Snapshot
Sediment filter: $30–$60/yr
RO filter changes: $150–$250/yr
Carbon media replacement: ~$400–$800 every 5–7 years
Backwash valve service: minimal if installed correctly
Total annual upkeep: ~$200–$350 average
4. Installation Notes
Install before the water heater (but after any irrigation split-off).
If irrigation is tied in, size bigger (3.0 cf tank, 13×54" tank) so watering the lawn doesn’t rob your showers.
Space needed: ~4–5 ft² floor + drain access.
Plumbing: 1" or 1.25" line in/out to avoid bottleneck.
5. Ballpark Costs
DIY: $2,000–$3,000 (parts + RO).
Pro-installed: $4,000–$6,000 for full POE + POU system.
ROI: higher home resale appeal (buyers love “whole-house filtration” bullet point).
✅ With this setup, you’ll eliminate chlorine odor, reduce disinfection byproducts, cover PFAS risk, and improve taste/health—all while maintaining good flow for three simultaneous showers.

CONCLUSION (for now)
What we ended purchasing is a CovePure Reverse Osmosis Water Filtration System. It cost approximately $799 off of Amazon, but believe my wife found it for $500 somewhere. I can confirm, if someone is interested. In following up, she purchased it for $450 and she purchased it directly from CovePure. Not sure if there was a model difference between the one purchased and the one I linked, but they make several.
The link to Amazon is directly to them, I do not have a storefront with them and get no benefit from someone making a purchase of it (just listing it informational purposes only.)
We like the taste and there is no smell. You can go cheaper, but this is the one we tried.
For one full container of tap water, which gets into in the rear of the unit (so, it would be hard to use unless siting out on our countertop somewhere), you get 2 liters of clean water and the remaining residual water in the rear tank in the rear needs to be tossed out. It is the yucky stuff! We're refilling it water several times a day.
We've been back filling Evian bottles and have cut that cost out of our budget. WeLikely, we'll find some glass bottles rather than use plastic... but, that is another rabbit hole for a later date.
I do believe the CovePure was a test and it proved its case with us and we'd prefer to cover all of our uses of water in the entire house.
In all likeliness, we'll be installing a whole house filter following the above recommendations. Preferably, I'd like to do this and then re-test the water for quality, accuracy, and to know exactly what we are consuming.
In the meantime, the CovePure does rate the water to be cleaned and also the purified water. We know it is significantly improved, but not the entire solution we are looking for.
So, our water quality is much better for our coffee, our cooking, even our dogs - and we have back off our regular purchase of Evian. Financially, we'll break even on the CovePure purchase in about 2-months of not purchasing our Evian water.
Our plumber has the spec sheet to quote us on the installation of the whole house purification system.
In the meantime, we'll tackle a few other home renovation projects first before we install the whole house system.
We already installed a Moen whole house "smart water leak detection system" to insure our completed projects don't get damaged or ruined. If you want to read my post on that, click here:
