For your convenience the WSD has posted current monitoring schedules. These schedules may change during the year; each water system will be notified in writing if this occurs.   Monitoring schedules change for a number of reasons.  For example, recent detection of contamination requires more frequent monitoring.  Monitoring schedules also need to be revised when changes in sources, the distribution system, treatment and storage facilities, or sampling location occur. Because of this, this web-posted schedule will be updated the beginning of every quarter to reflect these changes. For the most up-to-the-minute monitoring schedule, a water system operator should consult written correspondence from the WSD first.  (The Monitoring Schedules posted on the following links are up to date as of July 1, 2010)

The following contacts at the Water Supply Division can answer specific questions on your water system monitoring schedule. Call 1-800-823-6500 and then ask for the appropriate person below:
