Calhoun's PFAS Notice: What It Actually Means for Your Kitchen Tap

Start with the source, not a summary

In 2026, the City of Calhoun's utilities department posted an update regarding a drinking water health advisory level exceedance for PFOA and PFOS, compounds commonly called forever chemicals. That notice is posted directly on the city's own site, and it's worth reading in full there rather than relying on any secondhand summary, including this one. We're a plumbing and filtration company, not a water quality regulator, and we'd rather point you to the primary source than tell you how to feel about it.

What the notice does and doesn't mean, practically

A health advisory level exceedance means measured levels of PFOA and/or PFOS in the water supply exceeded the EPA's health advisory threshold, a specific regulatory benchmark. It doesn't, by itself, tell you what level was measured, how it compares to your specific health situation, or what action is right for your household; that judgment call is yours to make with your own research and, if you want it, a conversation with a healthcare provider, not ours to make for you.

What actually addresses PFAS, versus what doesn't

Not every filter marketed for general water quality is certified to reduce PFAS specifically. The detail that matters is an NSF/ANSI 53 or NSF/ANSI 58 certification listing PFOA and PFOS by name among the reduced contaminants, printed on the packaging or documented on the manufacturer's certification page. A basic activated-carbon pitcher filter, a whole-house sediment filter, or a filter that only claims to improve taste and odor is not automatically doing anything for PFAS, regardless of how the marketing reads.

A reverse osmosis system certified under NSF/ANSI 58 for PFOA/PFOS reduction, installed at the kitchen cold tap used for drinking and cooking, is the more targeted response if PFAS reduction specifically is your goal. It's a different system, and usually a different investment, than a whole-house carbon filter aimed at chlorine taste and general sediment.

If you're on a private well instead

The city's notice concerns the municipal water system specifically and doesn't apply to a private well. Well water quality depends entirely on the specific aquifer and location, which varies property to property in southern Gordon County and around Adairsville in particular, where private wells are common outside the incorporated areas. If you're on a well, an independent water test is the right first step, not an assumption based on what the city's system is reporting.

A mistake worth avoiding with water filtration systems

Buying a filter based on marketing language like removes contaminants without checking for a specific NSF/ANSI certification number and a list of exactly which contaminants were tested is the most common way people end up with a system that doesn't actually do what they bought it for. The certification details are usually printed in small text on the box or documented on the manufacturer's site; they're worth the extra minute to check before purchasing.

The other mistake is assuming a whole-house filter and an under-sink drinking water filter serve the same purpose. A whole-house system generally targets chlorine taste and sediment across every tap; a certified reverse osmosis system at one tap is what's typically needed for PFAS-specific reduction, and conflating the two leads to disappointment when the wrong system doesn't address the actual concern.

Where to actually go to read more

The City of Calhoun's own utilities pages are the right place for anything specific to the municipal water supply's current status, updates, and testing results, and the EPA's WaterSense and drinking water program pages provide general, non-commercial background on filtration standards and certifications. Neither of those sources is trying to sell you a filter, which makes them a more reliable starting point than a filtration company's own marketing material, ours included.

A practical step before buying anything

Requesting your household's specific water quality data, either from Calhoun Utilities' published water quality report if you're on city water, or from an independent lab test if you're on a well, gives you actual numbers to match against a filtration system's certified capabilities, rather than shopping based on general concern alone. That data also gives you something concrete to reference if you ever want a second opinion on which system genuinely fits your situation.

Filtration companies, including us, are generally happy to walk through a water quality report with you and explain what it does and doesn't indicate, which is a more useful starting conversation than jumping straight to a product recommendation before anyone has looked at your actual water.

A maintenance detail people forget after installation

Every filtration system, whether a whole-house carbon filter or an under-sink reverse osmosis unit, has filter cartridges that need periodic replacement on a schedule specified by the manufacturer, typically every six to twelve months depending on the system and household water use. A system running on an expired filter isn't necessarily doing nothing, but it's performing well below its certified capability, which defeats the purpose of having chosen a certified system in the first place.

Setting a calendar reminder for filter changes at installation time is a simple habit that keeps a system performing at the level it was actually chosen and paid for, rather than gradually declining unnoticed over months or years.

A word on where the system actually gets installed

A whole-house system installs at the point where the main water line enters the house, treating everything downstream, while an under-sink system installs specifically at one fixture, typically the kitchen cold line, and leaves every other tap in the house untreated. Knowing which of these matches your actual goal, whole-house taste improvement versus targeted drinking-water treatment, prevents installing the wrong type and being surprised that other taps in the house are unaffected.

It's also worth asking how a system's certified capacity is affected as it approaches the end of a filter's service life, since some systems maintain fairly consistent performance until the filter needs replacement while others degrade more gradually, which affects how strictly you need to stick to the replacement schedule.

A system's flow rate, measured in gallons per minute, also matters for a whole-house installation specifically, since an undersized system can noticeably reduce water pressure throughout the house, a tradeoff worth discussing before committing to a specific unit.
