Pratt, KS · City of Pratt · data through April 2026

Is Pratt tap water safe to drink?

Pratt's tap water comes from City of Pratt, which serves about 6,573 people. The federal data worth knowing about: PFOS above a 2024 EPA limit in at least one sample. Pratt County is EPA Radon Zone 1, the highest-risk tier, so a radon test is worth doing.

Chlorine or chloramine?

Looks fine

City of Pratt 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.

How hard is the water?

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

Lead and copper

Looks fine

In City of Pratt's most recent lead sampling, for the period ending December 2025, 90% of tested homes came in at or below 2.4 ppb of lead. That is low on any of the federal yardsticks.

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.

PFAS ("forever chemicals")

Take action

In EPA's 2023-2025 sampling of City of Pratt, these PFAS were detected: PFNA up to 6.2 ppt (2024 limit 10); PFBS up to 4.4 ppt (no federal limit); PFOS up to 4.1 ppt (2024 limit 4). PFOS was measured above the 2024 limit in at least one sample. These are the highest single results; utilities are judged on running annual averages, so a high sample is not by itself a violation.

Reverse osmosis is the most reliable home treatment for PFAS. Some carbon filters are certified for PFOA and PFOS reduction under NSF/ANSI 53; check the product listing for that claim, not just the word PFAS on the box.

CompoundHighest resultAvg. of detectionsDetections2024 EPA limit
PFNA6.2 ppt6.2 ppt110 ppt (planned rescission)
PFBS4.4 ppt4.4 ppt1none
PFOS4.1 ppt4.1 ppt14 ppt

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.

Health-based violations since 2016

Worth knowing

EPA's records show 8 health-based violations for City of Pratt since 2016: Nitrate (8). The most recent began in April 2026.

A violation records a period when a standard or treatment requirement was missed. It is not a description of today's water, and many are resolved within the quarter. The utility's annual report explains each one.

Radon

Take action

Pratt is in Pratt County, which EPA places in Radon Zone 1: the predicted average indoor level is above 4 pCi/L, EPA's action level.

In Zone 1, testing is the single highest-value home health check you can do. A $15-25 charcoal kit gives an answer in a few days; a digital monitor shows how levels move with the seasons. If you measure 4 pCi/L or more, a mitigation system (typically $800-2,500) brings it down permanently.

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 Kansas county's radon zone.

Air quality in Pratt

Worth knowing

EPA has no air monitor in or near Pratt County, so we only have smoke data here.

Wildfire smoke: NOAA satellites placed a medium or heavy smoke plume over Pratt County on about 28 days a year (48 in 2021, the worst year). That is above 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.

Radon + air quality monitor

EPA radon zone 1 of 3: one device answers radon and air quality.

One battery device that tracks radon alongside particles, CO2, humidity and VOCs. Worth it in a radon zone 1 or 2 county where you want both answers.

Furnace filter (MERV 11 to 13)

Central air? A better filter cleans the whole house every time the system runs.

If you have central heat or air, a pleated MERV 11 or MERV 13 filter catches fine particles such as smoke, dust and pollen from the whole house whenever the fan runs. EPA suggests MERV 13 or the highest your system can take: check your manual and match the exact filter size.

CO2 monitor

Stuffy bedroom or home office? CO2 tells you when to open a window.

CO2 is the best quick check on whether a room gets enough fresh air. Look for an NDIR sensor; cheap 'eCO2' sensors estimate it from VOCs instead of measuring it.
