Analysis

What to know about Alexandria's water

Alexandria ranks #131 out of 230 cities in Virginia for water quality, placing it below average in the state.

Alexandria 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.

As a small community water system, Alexandria may have fewer resources for advanced treatment technologies and infrastructure upgrades compared to larger utilities.

What Alexandria residents can do

Install a water filter

Recommended: NSF-certified water filter. This addresses the specific contaminants found in Alexandria's water.

Request your utility's CCR

Your water utility is required to publish an annual Consumer Confidence Report (CCR) with detailed testing results. Ask for the latest copy or check your utility's website.

Flush your taps

Run cold water for 30 seconds before drinking, especially in the morning. Lead and copper leach from household plumbing when water sits in pipes.
