Who provides Alexandria VA drinking water?

Virginia American Water, an investor-owned utility and a subsidiary of American Water, serves about 156,000 people in Alexandria from a Potomac River source. It is the only major Northern Virginia water provider that is a for-profit company rather than a public authority.

Why are Alexandria water rates different from Fairfax or Arlington?

Because of who sets them. Public authorities like Fairfax Water and Loudoun Water set rates through their own boards to recover costs. Virginia American Water's rates are set through rate cases before the Virginia State Corporation Commission, and those include an allowed return on equity. In the case settled in June 2026 the return on equity was set at 9.75 percent, on about $16 million of additional annual revenue against more than $115 million of system investment.

Is Alexandria VA tap water safe to drink?

It meets federal drinking water standards. Nine contaminants sit above the stricter health guidelines used by independent researchers, led by disinfection byproducts: total trihalomethanes around 45.1 ppb against a legal limit of 80, and haloacetic acids in the same pattern seen across Potomac systems.

Should I worry about lead in Old Town Alexandria?

Lead does not come from the utility's treated water. It enters from lead service lines, older solder and brass fixtures on individual properties, so in a city with a lot of pre-1986 housing it is worth testing your own tap rather than relying on a city-wide figure.

Alexandria's water is run by a for-profit utility

Its neighbours set rates at a board meeting. Alexandria's are argued before a state commission, with a profit margin in them.

Alexandria is the one Northern Virginia city whose water is delivered by a for-profit company rather than a public authority. Virginia American Water, a subsidiary of the largest publicly traded water utility in the country, serves about 156,000 people here. That single structural difference is why Alexandria's water rates get argued in front of a state commission while its neighbours' rates get set at a board meeting.

What investor-owned actually means for a bill

Fairfax Water, Loudoun Water and Arlington's utility are public. They recover costs, fund capital work and set rates through their own boards. Virginia American Water is investor-owned, so its rates are set through rate cases before the Virginia State Corporation Commission, and those proceedings include something a public authority's budget does not have: an allowed return on equity, which is the profit the company is permitted to earn on the capital it has invested.

The most recent round makes the mechanism concrete. Virginia American Water filed a general rate case in November 2025 seeking roughly $22 million in additional annual revenue against more than $115 million of system investment. In June 2026 the parties settled at about $16 million, with the allowed return on equity set at 9.75% rather than the 10.5% the company requested. The City of Alexandria was itself at the table negotiating that settlement.

This is a fact about structure, not a verdict about quality. Investor-owned utilities are held to the same federal drinking water standards as public ones, and Alexandria's water has stayed within federal limits. The difference shows up in how rates are set and who argues about them, not in which rulebook the water has to meet.

What is actually in Alexandria's water

Virginia American Water's Alexandria system draws from the Potomac River, and its published testing, compiled in the EWG Tap Water Database as of June 2026, shows nine contaminants above the health guideline:

Haloacetic acids (HAA9): 35.7 ppb, about 595 times the health guideline, with no federal legal limit for the HAA9 group.
Total trihalomethanes (TTHMs): 45.1 ppb, about 301 times the guideline, against a legal limit of 80 ppb.
Haloacetic acids (HAA5): 28.3 ppb, about 283 times the guideline, against a legal limit of 60 ppb.

Those are disinfection byproducts, and the pattern is the regional one: a Potomac source, mandatory chlorination, and a long trip through pipe. Alexandria's numbers sit close to Arlington's and DC's for exactly that reason. The full Alexandria readout shows all nine against both benchmarks.

The Alexandria-specific thing worth checking

Old Town and the older residential blocks contain a lot of housing built well before 1986. That matters because lead does not arrive in the water the utility delivers. It enters from service lines, solder and brass fixtures on individual properties. A city-wide number cannot answer it for your address, and neither can this site. It is the clearest case in the region for testing your own tap: why lead is a plumbing question, and how to test for it.

What helps

For the byproducts, carbon filtration for taste, or Reverse Osmosis (RO) at the kitchen tap for a thorough answer on drinking water.
For lead, Reverse Osmosis (RO) or a filter certified specifically for lead, at the tap you drink from, after testing to see whether you have it.
For hardness, the usual Potomac story: a wear problem for the water heater, not a health one.
