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. |

For the period from January 2000 to December 2007, there were and 2571 beach postings days for this section of shoreline. Bacteriological samples are collected on a weekly basis at approximately 150 ocean and bay location in Orange County. When a bacteriological sample exceeds water quality standards, signs are posted indicating that waters have exceeded public health standards.
Data and information on the number of beach posting were summarized by the County of Orange in their Annual Ocean and Bay Water Quality Report, March 2007. The reporting period was from January 2000 -December 2007. Data used was the number of days the beach was posting when the ocean or bay failed to meet the bacteriological standards. |

|
Data and Information Type: |
PWS pathogen monitoring (ambient water) |
Data Used to Assess Water Quality: |
Beach monitoring data was collected by the County of Orange from May 2004 through December 2006. A total of 123 single samples were collected with 6 samples correlated with a storm event. Of the 6 samples, 5 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. |

|
Water Quality Objective/Criterion: |
Geomean: Enterococcus density shall not exceed 35 per 100 ml.
Single Sample Maximum: Enterococcus density shall not exceed 104 per 100 ml (SWRCB, 2005). |

Spatial Representation: |
There is one sampling location located at North Doheny State Park Campground, DSB4, in the Lower San Juan HSA. This location is found in Doheny State Beach, approximately 200 yards south of San Juan Creek, Dana Point (Latitude 33.46070, Longitude -117.67749). |
Temporal Representation: |
Samples were collected at least once a week from May 2004 through December 2006. |
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. |
QAPP Information: |
Quality control for the bacteria analysis portion of this study was conducted in accordance with the County of Orange Quality Assessment/Quality Control document. |
