Smithfield VA Water Quality Report
See where Smithfield drinking water comes from, how the town treats it, what the latest Annual Water Quality Report shows, and what those results can—and cannot—tell you about water at your home.
What the Latest Smithfield Water Quality Report Covers
The Town of Smithfield's 2025 Annual Water Quality Report explains the town's groundwater source, reverse-osmosis treatment process, regulated monitoring results, lead and copper information, source-water protection and steps homeowners can take to protect water quality inside the home.
Important distinction: The town report summarizes public-system monitoring and compliance. It does not provide a complete water analysis for every individual faucet, service line, fixture or private well.
Where Smithfield Tap Water Comes From
Smithfield's municipal drinking water is groundwater pumped from two deep wells in the Middle Potomac Aquifer. The town uses reverse osmosis to reduce naturally occurring fluoride, then adds sodium hypochlorite and hydrated lime for disinfection, pH balance and corrosion control before water moves through the distribution system.

*Lead and copper values are reported as 90th-percentile results under the Lead and Copper Rule. **Chlorine compliance is based on the quarterly running annual average. ND means not detected. This summary does not replace the official report.
Two Smithfield Details Worth Understanding
Municipal Reverse Osmosis
Smithfield's reverse-osmosis plant has operated since September 2011. The town uses RO specifically to reduce naturally occurring fluoride in its groundwater before final treatment and distribution.
Finished-Water Fluoride
The 2025 report lists an average finished-water fluoride concentration of 1.19 ppm, with a reported range of 0.99–1.34 ppm and no violation.
Source Water Assessment
Virginia's 2002 Source Water Assessment classified the town wells as highly susceptible to contamination under the state's assessment criteria. That susceptibility rating describes source vulnerability; it is not itself a finding that the finished water violated a drinking-water standard.
Why Water at Your Faucet Can Differ From a Town-Wide Report
Smithfield's report explains that water quality can change after water passes the property meter because of service-line materials, household plumbing, fixtures and how long water has been sitting in the pipes.
Lead & Copper
The town samples homes for lead and copper on the required schedule. The report notes that these metals can come from service lines and household plumbing materials rather than the treatment plant itself.
Bacteria Sampling Locations
Smithfield reports 108 locations across the water system where bacteria samples are collected for analysis as part of routine monitoring.
Water After Time Away
The town advises flushing water after an extended absence because water sitting in plumbing for days can become stale and interact with plumbing materials.
Smithfield completed its Lead Service Line Inventory.
The town report says the inventory required by EPA's Lead and Copper Rule Revisions has been completed and can be reviewed by contacting Smithfield Public Works & Utilities.
What the Smithfield Water Quality Report Does—and Does Not—Tell You
A Consumer Confidence Report is the best starting point for understanding the municipal supply, but it is not a complete diagnosis of water conditions at a specific property.
What the Report Tells You
- Smithfield's municipal drinking-water source.
- How the town treats groundwater before distribution.
- Selected regulated contaminant and disinfectant results.
- Whether the listed results were reported as violations.
- Lead, copper, source-water and homeowner plumbing information.
What It May Not Tell You About Your Home
- Conditions caused by your own service line, plumbing or fixtures.
- How water tastes, smells or feels at a particular faucet.
- Whether a household wants additional drinking-water treatment.
- Conditions in a private well, which is separate from Smithfield's municipal supply.
- Which treatment system best fits a specific household concern.
