Data Used to Assess Water Quality: | Beach monitoring data was collected by the County of Orange from January 2004 through December 2007. Five samples were correlated with storm events. One of the five samples exceeded the single sample water quality objective. This information will not be used in determining a listing decision, but is of interest to the Regional Board and has been included here as additional anecdotal information. |

Temporal Representation: | Samples were collected weekly from January 2004 through December 2007. |
Environmental Conditions: | Comparisons were made for all data and data associated with storm events. A storm event was defined as 0.2 inches of rainfall within a 72 hour period.
Analyzing only storm water bacteria data is important because the majority of beach monitoring data covers the months of April through October. The data may not capture the full impacts of seasonal storm events and high bacteria levels due to storm water runoff because much of the wet season for Southern California occurs in November through March. |
