Result less than method detection limit for that analyte. <br />H = Analysis exceeded method hold time. pH is a field test with an immediate hold time. <br />1 - Total fraction of the analyte was analyzed rather than only the dissolved fraction. <br />Values in Bold exceeded benchmark levels. <br />Data from 1999 through 2000 are compiled from analytical results performed by ACZ Laboratories
