• 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 basetl upon the method and the sample matrix.
