Cumberland's drinking water received a grade of B+ (84.6 out of 100), indicating good water quality. The city's 1 water system serves approximately 1,840 residents using groundwater.

Lead levels were measured at 5.6 ppb (90th percentile), which is within EPA limits but above recommended levels. This system has not yet been tested for PFAS under the EPA UCMR 5 program. The system has 3 violations on record, including 0 health-based violations. 2 remain unresolved.

Cumberland ranks #110 out of 229 cities in Virginia for water quality, placing it mid-range in the state. Cumberland relies on groundwater, which is generally less vulnerable to surface contamination but can be affected by naturally occurring minerals like arsenic and nitrate, as well as agricultural and industrial runoff. While lead levels are within EPA limits, they are above the recommended 5 ppb threshold that health organizations consider ideal. A point-of-use filter adds an extra layer of protection. As a small community water system, Cumberland may have fewer resources for advanced treatment technologies and infrastructure upgrades compared to larger utilities.

04Where Cumberland's water comes from

Cumberland's drinking water is drawn from underground aquifers through wells.

Source

Groundwater

Underground aquifers reached by wells — naturally filtered, but can carry minerals like arsenic and nitrate.

Treatment

Local treatment

Groundwater generally needs less treatment — typically disinfection and, where needed, mineral removal.

Distribution

1 system

1 water system, operated under public/private ownership.

Delivery

1,840 people

Residents served across Cumberland's service area.

Groundwater is naturally filtered through rock and soil layers, generally requiring less treatment than surface water. However, it can contain naturally occurring contaminants like arsenic, radon, and minerals. Agricultural activity, septic systems, and industrial operations near well fields can introduce nitrates, pesticides, and volatile organic compounds. The system is operated by public/private ownership and serves approximately 1,840 people through 1 water system.

Flush taps & check your service line

Lead leaches from pipes as water sits. Run cold water 30 seconds before drinking (especially mornings), and ask the utility whether your address still has a lead service line.
