What's in Spotsylvania County, VA tap water?
Spotsylvania County sits about 57 miles from our Arlington base and is served primarily by Spotsylvania County Utilities, which provides water to roughly 95,700 people. It draws from the Potomac River watershed. Most of the DC metro area drinks treated Potomac River water. Because that surface water is heavily disinfected to stay safe across a long distribution system, the contaminants that most often exceed EWG's stricter health guidelines here are chlorination byproducts, alongside unregulated contaminants like PFAS and hexavalent chromium.

Measured by the EPA · Spotsylvania County, VA
Spotsylvania County, VA tap water is fully legal.
It is also 5.4× the health standard for lead.
Spotsylvania County is served by Spotsylvania County Utilities, a surface-water system supplying roughly 95,686 people. It treats its own water rather than buying it from a regional wholesaler, so what comes out of the tap is its work end to end.
River water has to be disinfected hard enough to stay safe across the whole network, and this system uses chloramines rather than free chlorine. Chloramine is more stable in long pipe runs and produces fewer trihalomethanes — but it is more corrosive to old plumbing, which is precisely how lead gets into water that left the plant clean.
Every federal limit that applies here is met. Those limits weigh what removal costs. EWG says its health standards are “based only on protecting health and does not consider technical feasibility or the cost of water treatment”. Here is how far apart the two are.
Harm to the brain and nervous system · EPA limit 10 ppb (action level, lowered from 15 ppb, in force November 2027)
Harm to fetal growth and child development · no federal limit exists
Harm to fetal growth and child development · no federal limit exists
The EPA's latest round found 2 PFAS compounds in this supply. Lead sampling put the ninetieth percentile at 1.07 ppb — meaning nine in ten homes tested below that, and one in ten above it. It has no violations on file.

How this water is treated before it reaches you
Treatment makes water safe to distribute. It is not designed to remove PFAS, and chlorine-based disinfection creates byproducts of its own.
Levels: EPA Fifth Unregulated Contaminant Monitoring Rule (UCMR5, 2023–2025) for PFAS, and the Lead and Copper Rule 90th-percentile result for lead and copper — the highest reported for Spotsylvania County Utilities. Health standards: EWG's published drinking water standards, updated February 2025. Levels vary by sampling point and date, and being above a health standard is not a legal violation.
9 contaminants above EWG's health guidelines

Enter your zip code above to see your exact utility's record.

Each of these is a plain-English guide to a contaminant class common in Spotsylvania County and the surrounding Potomac River watershed — what it is, the health context, and what actually removes it.
Reverse osmosis in Spotsylvania County, VA
Spotsylvania County Utilities treats this water to the federal standard, yet the contaminants listed above still exceed EWG’s stricter health guidelines — Total trihalomethanes (TTHMs), Haloacetic acids (HAA5), Hexavalent chromium (chromium-6) and 2 more. Most of them either pass straight through treatment or form after the plant, in the pipes between it and the tap, which is why the fix has to be at the tap as well.
Lead is the one nothing upstream can fix. It does not arrive from the treatment plant; it comes off the service line and the household plumbing in between, which is why two houses on the same street test differently. A reverse osmosis membrane sits at the end of that run, after every pipe the water has already passed through.
