Is Snook tap water safe to drink?

City of Snook uses free chlorine, based on its treatment records filed with EPA. Treatment records can lag changes, so confirm it in your utility's annual water quality report. Free chlorine is the easy case: almost any carbon filter, from a basic pitcher to a shower filter, reduces the taste and smell.

Chlorine also reacts with natural organic matter in the water to form byproducts called trihalomethanes (THMs). EPA limits them because drinking water above the limit for many years may raise cancer risk. Your utility's annual water quality report lists its THM levels. A carbon filter certified to NSF/ANSI Standard 53 for THMs reduces them.

We have no published hardness figure for Snook. City of Snook's annual water quality report usually lists it in milligrams per liter or grains per gallon.

In City of Snook's most recent lead sampling, for the period ending December 2024, 90% of tested homes came in at or below 5 ppb of lead. That is below EPA's action level but above FDA's 5 ppb limit for bottled water. A certified lead filter is a reasonable precaution, especially for children and pregnancy.

This is a system-wide statistic, not a reading of your tap. Lead comes from lead service lines, old solder and some brass fixtures inside homes, so two houses on the same street can differ. Testing your own tap costs $15-40, and many utilities test free on request.

EPA's lead action level is 15 parts per billion (ppb) today and drops to 10 ppb in November 2027 under the Lead and Copper Rule Improvements. FDA's limit for bottled water is 5 ppb. EPA's health goal for lead is zero.

City of Snook does not appear in EPA's 2023-2025 nationwide PFAS sampling (UCMR 5), or its results are not posted yet.

In April 2024 EPA set enforceable limits of 4 parts per trillion (ppt) for PFOA and PFOS, and 10 ppt for PFHxS, PFNA and HFPO-DA (GenX). In May 2025 EPA said it intends to keep the PFOA and PFOS limits, extend the compliance deadline to 2031, and rescind the other three. We compare results to the 2024 limits and label which ones may change.

City of Snook has no health-based violations on file with EPA since 2016.

Snook is in Burleson County, which EPA places in Radon Zone 3: the predicted average indoor level is below 2 pCi/L.

Zone describes a county average. Individual homes in every zone test high, so EPA recommends testing every home, especially basements and ground floors. Fix at 4 pCi/L or above.

EPA radon zones describe counties, not houses. Zone 1 counties have a predicted average indoor level above 4 picocuries per liter (pCi/L), Zone 2 between 2 and 4, Zone 3 below 2. Homes with high levels are found in every zone, which is why EPA recommends that every home be tested, and fixed at 4 pCi/L or above. See every Texas county's radon zone.

From 2021-2025, EPA monitors in the nearest monitored county, Brazos (TX), 30 km away rated 68.7% of days good. The air was unhealthy for sensitive groups or worse on about 0.2 days a year, at or below the typical US county (2.4). The pollutant behind most days was fine particles (PM2.5), and the worst single reading was an AQI of 102 in 2024.

Wildfire smoke: NOAA satellites placed a medium or heavy smoke plume over Burleson County on about 17 days a year (36 in 2023, the worst year). That is below the typical US county.

EPA's Air Quality Index runs from 0 to 500. Up to 50 is good and 51-100 is moderate. Above 100 the air is unhealthy for sensitive groups (children, older adults, and people with asthma or heart or lung disease), and above 150 it is unhealthy for everyone. We count a county's bad days as days above 100, averaged over 2021-2025. Smoke days come from NOAA satellite analysts, who draw where smoke plumes are overhead each day. A plume overhead does not always reach the ground, so these days measure exposure risk, not what you breathed. We count only medium and heavy plumes.

Indoors, where you spend most of your time

No agency measures indoor air city by city, so nobody can tell you your home's numbers except a monitor in your home. What research does show: Americans spend about 90% of their time indoors (EPA's National Human Activity Pattern Survey, 2001), EPA studies in the 1980s often found indoor levels of some chemical vapors two to five times outdoor levels, and during wildfire smoke the particles get inside unless windows stay shut and a filter runs.
