Drinking Water Quality: Schedules of Upcoming Monitoring

Monitoring Notification Documents

The Division of Drinking Water (DDW) has implemented a new procedure to access water quality monitoring notification documents. To access, go to the Drinking Water Watch website (https://sdwis.waterboards.ca.gov/PDWW/) and enter the Water System Number or the Water System Name for which you would like to search. From there, click on the ‘Water System No.’ to arrive at the ‘Water System Details’ page. On the left hand side of the page, click the ‘Monitoring Schedules’ link to arrive at the ‘Monitoring Schedules’ page. On this page, you will have the option to click ‘Monitoring Schedules for All Sampling Points’ or to click on the three digit ‘Sampling Point’ link which corresponds to individual sources (PS Codes). Once a monitoring schedule is accessed, you can export to excel, pdf, or word.
