Temporal Representation: |

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. |

Data Used to Assess Water Quality: |
For the period from January 2001 to December 2007, there were eight beach advisory days for this section of shoreline. Bacteriological samples are collected on a weekly basis at ocean and bay locations in San Diego County. When a bacteriological sample exceeds water quality standards, signs are posted indicating that an advisory for waters have exceeded public health standards.
Data and information on the number of beach posting were summarized by the County of San Diego in their annual San Diego County Beach Closure and Advisory Reports. The reporting period was from January 2001 - December 2007. Data used was the number of days the beach was advisories were issued when the ocean or bay failed to meet the bacteriological standards. |

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. |
