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