Fort Worth, Texas
Fort Worth, TX Water Quality
TRWD lakes and rivers, monochloramine disinfection, and published hardness. Here is what the City of Fort Worth 2025 report shows.
TRWD lakes · monochloramine avg 3.3 ppm · hardness 6–9 grains · lead 90th pct 3.1 ppb · TTHM 13.8 ppb.
The short answer
Fort Worth drinks surface water from six reservoirs and the Clear Fork of the Trinity River. Tarrant Regional Water District supplies the raw water; Fort Worth Water treats and delivers it.
The 2025 report lists monochloramine averaging 3.3 ppm, hardness of 6–9 grains, lead at 3.1 ppb at the 90th percentile with zero sites over the action level, and low disinfection byproducts (TTHM 13.8 ppb, HAA 9.3 ppb).

What filtration does — and does not
Carbon, catalytic carbon and reverse osmosis solve different problems. Fort Worth's report points at chloramine first.
Where Fort Worth water comes from
Six reservoirs, one river fork, five plants. TRWD moves the raw water; Fort Worth treats it.
Six reservoirs plus the Clear Fork
The 2025 report names Lake Worth, Lake Bridgeport, Eagle Mountain Lake, Benbrook Lake, Richland Chambers Reservoir, Cedar Creek Reservoir and the Clear Fork of the Trinity River.
TRWD raw water, Fort Worth treatment
Tarrant Regional Water District supplies raw water. Fort Worth Water treats and delivers it — about 79 billion gallons purchased from TRWD in Fiscal Year 2025.
Ozone, then monochloramine
Treatment includes ozonation, coagulation and flocculation, sedimentation, dual-media filtration, and monochloramine for the distribution system.
What the 2025 Fort Worth report actually says
Limits are fixed. Results are system figures from the Fort Worth 2025 Water Quality Report, not a reading at your tap.
Chloramine averaging 3.3 ppm
Monochloramine residual averaged 3.3 ppm in 2025 (range 0.93–4.7 ppm) against a 4 ppm maximum residual disinfectant level.
Very low disinfection byproducts
Total trihalomethanes were 13.8 ppb (range 2.28–22.1, limit 80) and haloacetic acids 9.3 ppb (3.2–13.6, limit 60).
Lead 3.1 ppb at the 90th percentile
In the 2025 Water Quality Report, lead was 3.1 ppb at the 90th percentile (0–5.1), with zero sites over the 15 ppb action level. Copper was 0.42 ppm.
Hardness 6 to 9 grains
Secondary results list total hardness as CaCO3 at 108–150 ppm, or 6–9 grains per gallon — moderately hard water that can leave scale.
Fluoride and nitrate
Fluoride ranged 0.14–0.90 ppm (limit 4) and nitrate 0.12–0.70 ppm (limit 10).
Bromate watched after ozonation
Bromate averaged 6.17 ppb with a range to 13.7 ppb against a 10 ppb limit. The report lists no violation.
Fort Worth next to Dallas and Houston
Dallas also uses Trinity-basin surface water and chloramine, but its 2025 report does not publish hardness. Fort Worth does: 6–9 grains. Houston blends two rivers with deep wells and reported two violations in 2025. Fort Worth's TTHM figure of 13.8 ppb is lower than Dallas's 19.7.
Further south, San Antonio and El Paso rely much more on groundwater and free chlorine rather than monochloramine.

Matching treatment to the finding
Fort Worth's report supports chloramine reduction and publishes hardness, so softening can be sized from the report plus a tap test.
Catalytic carbon for chloramine
Fort Worth disinfects the distribution system with monochloramine. Catalytic carbon is the usual whole-house answer when chloramine taste or smell is the complaint.
Softener sized to your tap
The report publishes hardness at 6–9 grains. A softener fits many Fort Worth homes, but a tap test still decides the grain capacity you need.
Reverse osmosis at the sink
Under-sink RO adds a drinking-water stage. The 2025 regulated results do not call for one against any single health contaminant.
Check your service line inventory
Fort Worth publishes an interactive lead material inventory map. Addresses listed as lead, galvanized requiring replacement, or unknown can request a free lead test.
How the free test works
A licensed technician tests at your kitchen tap, walks the plumbing, and tells you which of the findings above applies to your house and which does not. There is no charge and no obligation.
Seamless Home is the licensed contractor of record on the work that follows. Installation is performed by vetted installing partners engaged as our subcontractors, and the workmanship obligation stays with us. Coverage is confirmed per service area rather than promised as blanket availability.
What a water treatment job with us covers
Installation and replacement of whole-home and point-of-use treatment, specified against what your water actually contains.
Sediment filtration
Installation of the first stage that protects everything downstream of it, sized to the service line and the household draw.
Softening
Installation of ion-exchange softening where hardness is the problem, including the drain connection the plumbing code treats as indirect waste.
Carbon filtration
Installation of carbon stages for taste, odour and disinfection by-products, specified from your utility's own water quality report.
Reverse osmosis
Point-of-use installation at the kitchen sink where the target is dissolved solids rather than whole-home flow.
Disinfection
Installation of UV or equivalent treatment where the supply is a private well or is otherwise not continuously disinfected.
System replacement
Replacing equipment that has reached the end of its service life, including the discharge and air gap details an inspector looks at.
This is installation and replacement work, specified from a published water quality report or a test of your supply — not from a sales chart. Coverage is confirmed per service area rather than promised as blanket availability.
What the work actually looks like
Treatment equipment is plumbing. Most of the job is the connection, the drain and the code detail behind it.

Monochloramine. The 2025 report describes chlorine and ammonia added after filtration. The residual averaged 3.3 ppm in 2025.
Is Fort Worth water hard?+
Yes, moderately. Secondary results in the 2025 report list total hardness as CaCO3 at 108–150 ppm, or 6–9 grains per gallon.
Does Fort Worth have lead service lines?+
Lead is not in the water leaving the plant. The utility publishes a service-line inventory map; customers with lines designated lead, galvanized requiring replacement, or unknown can request a free lead test at 817-392-4477.
Is Fort Worth tap water within federal limits?+
The 2025 report states all results met state and federal drinking water standards. Your own tap can still differ because of the plumbing in your house.
