Information for Realtors

One of the first steps in obtaining water quality information for a home is to determine if it is served by a permitted water system. There are search engines available to look up the name of the water system by either address or assessor’s parcel number. The search engines have been split up by water system classifications so you may need to search in both places.

• Systems that serve 2-14 connections
• Systems that serve 15-199 connections

If your address/ parcel number does not have any matches, then the home is probably served by a private well, unpermitted water system, or a State Department of Public Health (CDPH) regulated system. Monterey County only regulates water systems with less than 200 connections. CDPH regulates systems with 200 or more connections. The water purveyor can be contacted for information on these larger systems.

WATER QUALITY

The last few years of water quality information for systems that serve 2-14 connections can be found on our Local Small Water System webpage. This page also has links to information regarding arsenic and nitrates, which are common drinking water contaminants in Monterey County.
