Sampling Design: The Recreational Water Quality program is implemented in full compliance with the federal BEACH Act. The indicator organism used to test is called enterococcus, and when levels are exceeded based on the tiers below, a swimming advisory or alert is issued.
* Tier 1 - These beaches are used on a daily basis. All ocean beaches are considered Tier 1-single sample maximum 104 enterococci per 100 ml water or a running monthly average (geometric mean) of 35 enterococci per 100 ml water. There are 92 Tier 1 sites.
* Tier 2 - These beaches are used an average of three times per week. The single sample maximum is 276 enterococci per 100 ml water. There are 104 Tier 2 sites.
* Tier 3 - These beaches are used an average of four times per month, or used less frequently but intensively for special events such as triathlons. Single sample maximum for these sites is 500 enterococci per 100 ml of water. There are 44 Tier 3 sites.
