The verdict
Blacksburg, Town Of is in the lower third by violation count (4; lower-third violation load (≤ 21 violations)). A low count does not mean the system is unmonitored - monitoring and reporting violations still appear in SDWIS. Population served is large (34,578; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 75% - most of this ledger is MCL or treatment-technique exceedance. UCMR5 tested this system and reported no PFAS above the minimum reporting level.
