Smithfield treats its own Neuse River water and disinfects it with chloramine; the 2025 report doesn't list hardness, so a softener is a test-first decision. A carbon filter for taste is the more common fit, and with sodium already at 37.9 ppm, people watching salt should think twice about softening.

What's in Smithfield's water?
The Town of Smithfield runs its own treatment plant on North 2nd Street, drawing from the Neuse River with a permitted withdrawal of up to 8.3 MGD and a 24-million-gallon off-stream reservoir. The 2025 water quality report shows chloramine disinfection with a running average of 2.82 ppm and chlorine at 0.48 ppm. Sodium was 37.9 ppm and pH 7.6. Hardness isn't reported. Lead was below detection at the 90th percentile, with no sites above the action level. A separate district, Smithfield South, gets its water from Johnston County Utilities, so check which system your bill names.
Were there any violations I should know about?
One, and it was paperwork. The town didn't send the required lead service line notifications by the 2025 deadline and sent them on March 11, 2026. The report also notes that the removal ratio for total organic carbon dipped below 1.00 in the third and fourth quarters of 2025, but alternative compliance criteria were met. Neither is a measured health exceedance. If you'd like extra assurance at the drinking tap anyway, an under-sink filter certified for lead and for chloramine covers both concerns at once.
Should an older Smithfield home get a softener?
Only if testing shows hard water. About 65% of Smithfield homes were built before 1980, and in houses that age, scale or stains often come from aging pipe or an old water heater rather than the supply. Softening also adds sodium, and Smithfield's water already carries more than most nearby systems. A plumber can test your hardness, check the water heater and pipes, and tell you whether a softener, a filter or a repair is the right spend. Building inspections in Smithfield are handled by Johnston County under contract, with a town zoning permit first, if the work requires one.
A short note: homes outside town in the 27577 area may be on Johnston County water or private wells. Well water should be tested for hardness, iron and bacteria before choosing treatment. And if you're on the Smithfield South district, read Johnston County's report rather than the town's, since the water comes from a different plant and its numbers may differ.
