| Data Used to Assess Water Quality: | Available data indicate sufficient exceedances of bacterial indicator objectives. There were 74 out of 698 samples that exceeded the single sample maximum for total coliform, 120 out of 698 that exceeded the single sample maximum for enterococci, and 233 out of 646 exceedances of the geomean for enterococci (USEPA, 2007). | ||||

| Water Quality Objective/Criterion: | Title 17 C.C.R. Section 7958 states: Based on a single sample, the density of bacteria in water from each sampling station at a public beach or public water contact sports area shall not exceed:
(A) 1,000 total coliform bacteria per 100 milliliters, if the ratio of fecal/total coliform bacteria exceeds 0.1; or (B) 10,000 total coliform bacteria per 100 milliliters; or (C) 400 fecal coliform bacteria per 100 milliliters; or (D) 104 enterococcus bacteria per 100 milliliters. Based on the mean of the logarithms of the results of at least five weekly samples during any 30-day sampling period, the density of bacteria in water from any sampling station at a public beach or public water contact sports area, shall not exceed: (A) 1,000 total coliform bacteria per 100 milliliters; or (B) 200 fecal coliform bacteria per 100 milliliters; or (C) 35 enterococcus bacteria per 100 milliliters.
