Post Fire Water Quality Reports
To ensure the safety of the public water supply following the wildfire, the State Water Resources Control Board, acting through its Division of Drinking Water and in collaboration with Waterworks District 29, has extensively collected water samples to analyze for volatile organic chemicals (VOCs) potentially found in water systems after fires. Below is a table displaying the detailed results

ABBREVIATIONS:
Maximum Contaminant Level (MCL): The highest level of a contaminant that is allowed in drinking water. Primary MCLs are set as close to the Public Health Goals as is economically and technologically feasible. Secondary MCLs are set to protect the odor, taste, and appearance of drinking water.
Detection Limits for Purposes of Reporting (DLR): The DLR is a parameter that is set by regulation for each reportable analyte. It is not laboratory specific and it is independent of the analytical method used (in cases where several methods are approved). It is expected that a laboratory can achieve a Reporting Limit that is lower than or equal to the DLR set by the DDW.
N/A: Not Applicable.
ND: Contaminant was Not Detected.
ppb: parts per billion
