Fecal Indicator Bacteria In wine there is wisdom,
In beer there is freedom,
In water there is bacteria.

FIB: Summary
BMPs and overall flow reductions resulting in significant reductions in dry weather
Successful dry weather bacteria BMPs appear ineffective in providing meaningful wet weather reductions
Overall reduction in the number of sewage spills correlates with lower number of beach closures and increased recreational water use. (Countywide Area Spill Control Program – CASC)
Decrease in the total number of beach mile days posted due to AB411 standards violations has increased beneficial use. Example: Doheny
