Tell us which side of Ox Road you live on and you’ve mostly told us whether you have a well. Of the roughly 1,760 active well records the Health Department lists in 22039, about 95 percent sit west of Ox Road, on the five-acre lots the county plan keeps in the Occoquan watershed. Crosspointe barely shows up: six well parcels. Hampton Road has the most records by far, then Henderson Road, Fairfax Station Road, Wolf Run Shoals Road and Yates Ford Road.
The permit dates cluster in the 1970s and 80s, close to six in ten of them, and that lines up with the houses: the Census puts eight in ten Fairfax Station homes between 1980 and 1999, almost all detached. So most wells here have been in the ground 35 years or more. The pump has likely been swapped at least once, the tank more than that, and the wire and drop pipe may still be from the day the well went in.
Water chemistry is the other Fairfax Station story. In September 2026 a homeowner here had already pulled a 110 foot pump himself before calling us. It was the third pump on that well, and the water was acidic. Acidic water is hard on pumps, copper and fittings, so when a well keeps eating pumps, the fix starts with a water test and often a neutralizer, which the Health Department lists with softeners and UV lights as treatment to check regularly.
Equipment in these utility rooms tends to age together. In February 2026 a Fairfax Station call about a dead electric water heater turned into a look at the 86 gallon well tank beside it, and we priced both. When one big piece in that room is failing, have the others checked at the same visit, since they’re often about the same age.
