Well Water in Falls Church city: What to Test and Why

Nitrate and nitrite are present in Falls Church groundwater, though contaminant levels here are low and do not exceed EPA health standards.

Nitrate and nitrite come mainly from septic systems and fertilizers used on lawns and gardens throughout the city. The crystalline rock underneath Falls Church does not hold onto these chemicals the way softer rock would, so they flush through fairly quickly and do not accumulate to high levels.

Groundwater in this county is hard, driven by calcium and magnesium released from the crystalline rock as water passes through. This rock weathers slowly, so minerals dissolve into the water over time. Elevated hardness is common across wells in the area.

Wells in Falls Church show good water quality overall, with no contaminants exceeding EPA health standards. Nitrate and nitrite levels in county wells are being monitored as a precaution, though they are not currently at concerning levels in most areas. Your well water appears to be in good shape based on county data.

Information about mineral content like iron and sodium levels is not available for this area, so we cannot describe common staining, taste, or other quality-of-life concerns that might affect your specific well. Your water chemistry may be quite different from your neighbor's well.

We recommend testing your well to know exactly what is in your water and whether any treatment would help. Testing is the only way to confirm what your individual well contains. A basic screening test for bacteria and nitrate runs about fifty to one hundred dollars and gives you solid information. If you find any concerns, simple treatments like aeration or ion exchange can address most common issues.
