The disparity between dry and wet weather water qualitycontinues to be dramatic, thereby demonstrating that [California]is not successfully reducing stormwater runoff pollution.Dockweiler Beach. Photo: Joy Aoki
2010-2011 AnalysesOverall water quality during the summer dry (AB411) time period inCalifornia this past year was very good and was equivalent to the seven-year average(years since new methodology implementation). Of the 445 ocean water quality monitoringlocations throughout California, 400 (90%) received very good to excellent water qualitymarks (A or B grades) from April through October 2010 (see Figure 3-1).Southern California (Santa Barbara through San Diego) summer dry (AB411) grades (91% A and B grades)were slightly better than the statewide average. There were 45 (10%) monitoring locations statewide thatreceived fair to poor water quality marks (C–F grades) during the same time period.During year-round dry weather, most California beaches had very good water quality, with 284 of 324(88%) locations receiving very good to excellent (A and B) grades. Lower grades during the same timeperiod include: 12 Cs (4%), 12 Ds (4%) and 16 Fs (5%). Southern California (Santa Barbara through SanDiego counties) year-round dry weather grades (89% A and B grades) were just slightly better than thestatewide average. Los Angeles County again exhibited some of the lowest grades in the state (76% Aand B grades) for year-round dry weather.In the San Francisco Bay Area (Marin through San Mateo counties), summer dry weather grades wereexcellent on the ocean-side with 95% (40 of 42) of the locations receiving A or B grades, and fair onthe bay-side with 19 of 26 (73%) receiving A or B grades. Forty-one of 68 (60%) of Bay Area locationswere monitored year-round. Year-round dry weather water quality at ocean-side monitoring locationswas very good with 18 of 20 (90%) of receiving an A or B grade, and fair on the bay-side with 14of 21 (67%) receiving A or B grades.In California, the disparity between dry and wet weather water quality continues to be dramatic anddemonstrates that the state is not successfully reducing stormwater runoff pollution. 46% percent ofmonitoring locations received fair to poor grades during the wet weather season with 22% F gradesA B C D FWith the exception of educationalprograms, there have been no majorefforts made by public agencies alongthe coast to target reductions in fecalbacteria densities in stormwater.(see Figure 3-1). This marked seasonal difference in water quality iswhy Heal the Bay and California’s public health agencies continueto recommend that no one swim in the ocean during, and for atleast three days after, a significant rainstorm. With the exception ofeducational programs, there have been no major efforts made bypublic agencies along the coast to target reductions in fecal bacteriadensities in stormwater. (A list of all the California grades can befound in Appendix C1.)While 60 monitoring locations were monitored throughout the summerin Oregon, only 13 were monitored frequently enough (at leastweekly) to be considered for this report. All of Oregon’s 13 regularlymonitored locations received A grades. Washington locations were also typically clean with 93% ofthe 141 monitored receiving A and B grades.21
