Question 8

How does Tyrone's violation count compare nationally?

Accepted Answer

Tyrone has 224 recorded EPA SDWIS violations, fewer than 13% of the 29,740 public water systems serving 500 or more people nationwide (the same sitemap cohort used for the corpus-placement ranking above). 87% of that cohort has fewer violations than Tyrone. A system can have zero recorded violations and still be actively monitored, and a high violation count often reflects a system that reports thoroughly, not necessarily one with worse water.
