Water Quality Data

How to Read the Tables

The water quality data tables list contaminants which 1) CDPH requires the City to monitor, 2) CDPH regulates with associated primary [health] or secondary [aesthetic], or no established standards. During 2013, these contaminants were detected at or above the CDPH's Detection Limits for Purposes of Reporting during the reporting year.

These tables summarize monitoring from January - December 2013 with two exceptions (see table footnotes). The CDPH mandates monitoring radioactive contaminants every three years. The Lead and Copper Rule was conducted in 2011, and is monitored every three years. The levels of these contaminants are not expected to vary significantly from year to year.
