Hardness
Moderately hard to hard108–150mg/L as CaCO₃
Range in secondary-constituent table
The range crosses the USGS hard-water threshold of 121 mg/L; hardness concerns scale and spotting, not a health violation.

Your water at a glance
See the amount, the comparison and what it means. “Below” refers to the stated benchmark, not zero risk.
Chloramine
Below 4 ppm MRDL comparison3.3ppm
“Your water” value in the results table; range 0.93–4.7 ppm
Chloramine is used for disinfection. A filtration system targeting it needs the appropriate media and contact time; a single sample is not the same as the regulated annual measure.

This system-level sampling statistic is not a result for your home; plumbing can affect lead at an individual tap.

This does not establish whether PFAS are present or absent. Check compound-specific testing before choosing treatment.

ppm ≈ mg/L; ppb ≈ µg/L; ppt ≈ ng/L in drinking water. Hardness in gpg = mg/L as CaCO₃ ÷ 17.1. ND means not detected at the method’s reporting limit—not zero.
MCL is a maximum contaminant level. MRDL is a disinfectant limit. Lead/copper action levels use system sampling percentiles and are not a safe-tap threshold. TTHM/HAA5 compliance uses locational annual averages.
PFOA/PFOS comparisons use EPA’s 4 ppt values. Historical detections are not a present compliance finding; EPA assesses compliance using running annual averages. Rule implementation is being reviewed. EPA PFAS benchmarks and implementation ↗

Source water. Fort Worth treats surface water from Lake Worth, Lake Bridgeport, Eagle Mountain Lake, Benbrook Lake, Richland-Chambers Reservoir and Cedar Creek Reservoir. The report also notes a short supplemental supply from TRA in late 2025.

More about your local water
What this means for your home
Understand the hardness range and chloramine results.
Fort Worth treats surface water from several reservoirs. The report labels some results as ‘Your water’ and lists individual ranges separately; these are retained rather than relabelled as tap measurements. Customers of another retail utility should use that utility's report.
A useful local question
Does Fort Worth water support a softener recommendation?
Its reported 108–150 mg/L hardness range reaches the hard category. Filtration plus softening makes sense when reducing scale and spots is a goal; a current incoming-water test determines the home's actual softener setting.
Sources and methodology
We keep each utility’s results separate, show the reported sample year, and distinguish averages, maxima and tap-sampling percentiles. Hardness classifications use USGS ranges. Missing data stays unknown.
