We Exist Because
Austin's Water
Deserves Honesty.
AustinWaterGuide is an independent, editorially rigorous resource built by a WQA-certified water treatment specialist who got tired of seeing Austin homeowners pay too much for systems they didn't need — or too little for ones that didn't work.
John Rodriguez,
Water Treatment Specialist
John Rodriguez grew up in a Central Texas household that relied on a private well. A childhood of hard-water scale, iron staining, and the occasional "rotten egg" smell gave him an intuitive sense that most people didn't have the tools to understand — or fight back against — what was coming out of their taps.
After earning his certification through the Water Quality Association (WQA) — the industry's gold-standard professional body — John spent nearly a decade working alongside licensed plumbers and water treatment installers across Travis, Williamson, and Hays counties. He has personally assessed water quality reports for homes in Tarrytown, South Lamar, Cedar Park, Bee Cave, Dripping Springs, and rural Wimberley. He has seen first-hand the difference a correctly specified whole-house catalytic carbon filter makes for a family dealing with chloramine byproducts, and equally, the frustration of a homeowner sold a $4,000 system that solved a problem they didn't have.
That frustration — watching people get misled by dealer sales tactics and SEO-optimized affiliate mills — is what drove him to build AustinWaterGuide in 2018.
"My job is to tell you exactly what's in Austin's water, exactly what technology removes it, and exactly which product gives you the best outcome for your budget. Not the product with the best affiliate commission rate."
— John Rodriguez, Founder, AustinWaterGuideJohn holds a current Water Quality Association Certified Water Specialist (CWS) designation and has maintained continuing education hours through WQA's annual conference and online curriculum. He cross-references all product performance claims against NSF/ANSI Standard 42, 44, 53, 58, and 61 certification data and personally reads Austin Water's Consumer Confidence Report each year upon release, tracking year-over-year shifts in disinfection by-product levels, turbidity spikes, and seasonal hardness variance.
He lives in Austin with his family and, yes, has a SpringWell CF1 and SS1 installed in his own home — systems he recommends because he uses them, not merely because they pay a commission.

Eight Years Tracking
Every Drop Out of
Austin's Taps.
AustinWaterGuide launched the year Austin Water's Consumer Confidence Report revealed TTHM levels at 34.8 ppb — levels 232 times higher than EWG's health guideline. Most residents had never heard of trihalomethanes. Most had no idea their municipal water was disinfected with chloramines, not chlorine, and that the distinction matters enormously when selecting a carbon filter.
The gap between what Austin homeowners were being told and what the data actually showed was too large to ignore. This site exists to close that gap.
2018
AustinWaterGuide Launches
John publishes Austin's first homeowner-focused deep-dive into the city's chloramine disinfection switch and its implications for carbon filter selection.
2019
EWG Contaminant Database Integration
We cross-reference Austin's annual CCR against EWG's health guidelines — not just EPA MCLs — for the first time, revealing the 42-contaminant gap that defines our editorial frism.
2021
Well Water Coverage Expands
Growing inquiries from Dripping Springs, Wimberley, and Bee Cave prompt a dedicated well water section, covering iron, H₂S, hardness, and bacterial contamination.
2023
PFAS Coverage Adds Urgency
EPA's PFAS Maximum Contaminant Level proposals reach final rule status. We publish Austin's first homeowner guide to PFAS treatment options and RO system selection for PFOA/PFOS removal.
2026 — Today
Comprehensive Multi-System Guidance
Full coverage of whole-house filtration, water softening, reverse osmosis, salt-free conditioning, and combination systems — all calibrated specifically to Austin's water chemistry.
Our Research
Methodology
Every recommendation on this site follows a documented process. We do not publish product opinions — we publish product analyses grounded in chemistry, independent testing data, and Austin-specific water conditions.
Step 01
Water Quality Data Analysis
We read Austin Water's CCR in full upon annual release, log detected contaminant levels in a maintained database, and benchmark every figure against both EPA MCLs and EWG's more protective health guidelines.
Step 02
NSF Certification Verification
Before any product is reviewed, we verify its NSF certification status directly at nsf.org. We confirm the specific contaminants each certification covers and cross-reference with Austin's detected contaminants to assess actual relevance.
Step 03
Technology Selection Logic
We map each Austin contaminant concern to its correct removal technology: catalytic carbon for chloramines, ion exchange for hardness, RO membranes for TDS/PFAS, UV for biological threats. This governs all recommendations.
Step 04
Hands-On Product Evaluation
Where possible, John evaluates products in the field — reviewing installation documentation, filter media quality, flow rate specifications, and maintenance burden. Priority products are cross-checked with third-party lab test reports.
Step 05
Cost of Ownership Modelling
Every recommendation includes a 5-year total cost of ownership projection: hardware, installation, filter replacements, salt (where applicable), and water waste (for RO). We factor Austin-specific plumber labour rates.
Step 06
Annual Review Cycle
We review every product recommendation annually. When Austin Water's data shifts, when NSF certifications are updated, or when better products enter the market, we revise our recommendations — regardless of affiliate impact.
How We Maintain
Independence.
Affiliate income funds this site. That is a fact we disclose prominently and without apology. But it does not govern this site.
The distinction matters. Many water filter websites are built backwards — they identify the products with the best commission rates and write content to justify those recommendations. We work in the opposite direction: we identify the best products for Austin's specific water chemistry and then disclose if an affiliate relationship exists.
"If a product earns zero commission but is genuinely the best solution for a reader's problem, we recommend it. That has happened, and it will happen again."

Content Dating & Freshness
All pages display a "Last Updated" date. Key water quality data is refreshed each year when Austin Water releases its annual Consumer Confidence Report.
Primary Sources Only
Water quality claims cite Austin Water CCRs, EPA databases, EWG's Tap Water Database, NSF International, or peer-reviewed research — never aggregator blogs.
We Read the Primary Sources.
So You Don't Have To.
Where we cite third-party data, we link directly to the primary source. We do not aggregate from other water filter review sites or republish secondary sources without independent verification.
Austin's Water
Is Unlike
Anyone Else's.
Austin's hardness is classified as "very hard" — the top tier. Most national water filter guides don't account for this.
A generic water filter guide written for a national audience is almost useless for an Austin homeowner. Here is why:
- Chloramines, not chlorine: Austin Water uses chloramines as its primary disinfectant. Standard activated carbon — recommended everywhere online — does not effectively remove chloramines. You need catalytic carbon. Most national guides don't mention this distinction.
- Extreme hardness: At 10–16 GPG, Austin's water is among the hardest in any major US city. A filter guide that doesn't prominently feature water softening is incomplete for this market.
- Highland Lakes source variability: Austin draws from Lake Travis and Lake Austin. Drought years compress the watershed, raising TDS and hardness. Wet years see algae bloom events that produce geosmin and MIB taste compounds. Seasonal guidance matters.
- PFAS now in the conversation: EPA's 2024 PFAS MCL final rule directly impacts how Austin residents should evaluate their RO system choices. This is live, evolving guidance — not something a 2021 article covers.
- Rural well water surrounds the city: The Hill Country belt — Bee Cave, Dripping Springs, Wimberley, Marble Falls — relies on private wells with entirely different chemistry profiles: iron bacteria, hydrogen sulfide, and variability that municipal water never presents.
AustinWaterGuide exists because all of this requires someone who is here, who reads the local data, and who has walked into Austin homes and seen the scale deposits firsthand. National guides are a starting point. We are the answer.
