Results for CWSC SALINAS HILLS
1 water provider directly on file, serving roughly 5,293 people in Monterey County, California.
Quick answer: CWSC SALINAS HILLS has no violation currently counted toward its compliance status. EPA's record shows a Arsenic violation dating to 08/01/1985 (41 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.
