• 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.
