" Constituents reported in mg/I unless otherwise noted. <br />A symbol "<" before a number indicates that the value is not detected. The number following W is the analytical limit of detection based upon the method and the sample matrix. <br />Analyte concentrations reported below the detection limit are set equal to one half the detection limit for all statistical calculations.
