Quick answer: MILPITAS's water has no violation currently counted toward its compliance status. EPA's record shows a Surface Water Treatment Rule violation dating to 03/01/1995 (31 years ago) — because it's more than five years past its deadline, EPA's policy no longer treats it as part of this system's current standing, though it remains on the public record.
