'Sample Type =Primary (one sample is represented). =Average (duplicate samples are averaged). " Constituents reported in mg/I unless otherwise noted.
A symbol "<^ Defore a number indicates that the value is not detected. The number following "<^ ~s the analytical limit of detection based upon the methotl antl the sample matrix.
