` 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.
Analyte concentrations reported below the detection limit are set equal to one half the detection limit for all statistical calculations.
