' Sample Type =Primary (one sample is represented), =Average (duplicate samples are averaged). "Consbluents reported in mg/I unless otherwise notetl.
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.
