Notes
The monitoring program and regression equations are for the period of March through October each year (no bacteria data collected during Nov-Feb so estimate of FC concentrations during that period are not validated.) The near real-time estimates of fecal coliform concentrations are computed using provisional near real-time turbidity data which are subject to revision.
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.
