Notes

A water-quality criterion or standard of 200 col/100mL for fecal coliform bacteria is plotted as a horizontial dashed line (more...). A second, smaller plot indicates the statistical probability that the computed values have exceeded this criterion or standard.

The statistical (regression) model used to compute fecal coliform bacteria is site specific. Gaps in data occur either when data are not available or their values are outside of the range for the regression model. Users should consider these factors, as well as uncertainty associated with regression-model computed data, when applying this information to specific issues.
