Notes

The continuous water quality monitor at this site operated from 1999-2005 and was re-deployed in August 2012.

A water-quality criterion or standard of 20 mg/L for sodium 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 sodium 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.
