     General Comments
     The analytical procedures used by ALS have been developed from established internationally recognised procedures such as those published by the USEPA, APHA, AS and NEPM.                                   In house developed procedures
     are fully validated and are often at the client request.
     Where moisture determination has been performed, results are reported on a dry weight basis.
     Where a reported less than (<) result is higher than the LOR, this may be due to primary sample extract/digestate dilution and/or insufficient sample for analysis.

     Where the LOR of a reported result differs from standard LOR, this may be due to high moisture content, insufficient sample (reduced weight employed) or matrix interference.

     When sampling time information is not provided by the client, sampling dates are shown without a time component. In these instances, the time component has been assumed by the laboratory for processing
     purposes.
     Where a result is required to meet compliance limits the associated uncertainty must be considered. Refer to the ALS Contract for details.

     Key :          CAS Number = CAS registry number from database maintained by Chemical Abstracts Services. The Chemical Abstracts Service is a division of the American Chemical Society.
                    LOR = Limit of reporting
                    ^ = This result is computed from individual analyte detections at or above the level of reporting
                    ø = ALS is not NATA accredited for these tests.
                    ~ = Indicates an estimated value.
     l   EG048G (Hexavalent Chromium by Alkaline Digestion): Sample EB2307800_003 (TP10-0.5) was diluted due to matrix interference. LOR adjusted accordingly.
     l   EG048G (Hexavalent Chromium by Alkaline Digestion): Sample EB2307718_001 shows poor matrix spike recovery due to matrix interferences.
