Tazewell County, VA
drinking water quality
38,875 residents · 22 public water systems · 15 ZIP codes
EPA sampled 6 of 22 public water systems here, together serving about 25,513 people. EPA detected PFBA at 13 ng/L. EPA has not set a drinking water limit for PFBA, so there is no figure to compare it against. Last sampled 9/22/2025.
What this means
PFAS are industrial chemicals that EPA describes as breaking down only very slowly in the environment. In April 2024 EPA set the first enforceable national limits: 4 ng/L for PFOA and PFOS, 10 ng/L for PFHxS, PFNA and GenX.
These figures are county-level and come from EPA’s sampling of public water systems. They describe the worst result found in the county, not what comes out of any particular tap — that depends on which system serves the address, and on the plumbing in the building. A private well is not covered by this programme at all.
