• Sample Type =Primary (one sample is represented), =Average (duplicate samples are averaged). •" Constituents reported in mg/I unless otherwise noted.
A symbol'<' before a number indicates that the value is not detected. The number following "<" is the analytical limit of detection based upon the method and the sample matrix.
