Question 8

How does Britton's violation count compare nationally?

Accepted Answer

Britton has 78 recorded EPA SDWIS violations, fewer than 32% of the 29,740 public water systems serving 500 or more people nationwide (the same sitemap cohort used for the corpus-placement ranking above). 68% of that cohort has fewer violations than Britton. 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.
