The cards below show the details and the official sources.

At a glance

Water test for a new wellRequired

Yes. A private well needs a construction permit from the local health department before drilling, must be built by a DPOR-licensed contractor with the Water Well/Pump specialty to the Private Well Regulations (grouted casing, setbacks of 50 ft from septic tanks and 100 ft from drainfields), and after completion the health department inspects it and requires a bacteriological sample that passes before the well is placed in service. The inspection statement is your record of the well.

Water test when a home is soldNot required statewide

No statewide requirement. The Residential Property Disclosure Act does not require a water test. FHA, VA and USDA loans normally require a bacteria, nitrate and lead sample from a certified lab before closing, and buyers can ask the local health department for the well's construction permit and inspection file.

What the state recommends

The Virginia Department of Health and the Virginia Household Water Quality Program recommend a coliform bacteria test every year and nitrate at least every three years, with a broader first test for hardness, iron, manganese, pH, sodium, copper, lead, arsenic and fluoride. Add radon and uranium in the Piedmont and Blue Ridge, sodium and chloride in Coastal Plain wells, and test again after flooding, well work or a change in taste, color or smell.

Free or low-cost testingAvailable

The Virginia Household Water Quality Program (Virginia Tech and Virginia Cooperative Extension) runs county drinking water clinics through the year: you pick up a kit from the Extension office, drop the sample back, and get results for 14 tests (bacteria, nitrate, metals, hardness, pH and more) with an interpretation meeting, for about $65, free in counties with grant funding. Local health departments and the VDACS regional animal health laboratories also run a bacteria test for a small fee.

Well depth and water chemistry

Wells in Culpeper County typically reach 100 to 300 ft in the Coastal Plain sands east of I-95; 200 to 500 ft in the fractured rock of the Piedmont; 150 to 400 ft in the limestone valleys of the Shenandoah and Valley and Ridge; 200 to 600 ft in the Blue Ridge and the southwest coalfields. What comes up with the water depends on the aquifer, and across Virginia the usual suspects are coliform bacteria (the most common failure statewide, worst in the piedmont and the valley), hardness (shenandoah valley and other limestone areas), iron and manganese (coastal plain and piedmont). A first full panel tells you which of them apply to your well.
