Water Delivery & Quality

Water Quality

The City of Petaluma wants people to know as much as possible about our water quality and supply. In our experience, the more informed people are about their tap water quality, the more confidence they have in it. The City strives to continue to deliver the best quality water to our customers staying well within the strict federal EPA, and California Division of Drinking Water guidelines. Below is a list of water quality reports you can review.

If you have questions or concerns regarding water quality, please contact the City of Petaluma Public Works & Utilities Department at (707) 778-4546.
