     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   Benzo(a)pyrene Toxicity Equivalent Quotient (TEQ) per the NEPM (2013) is the sum total of the concentration of the eight carcinogenic PAHs multiplied by their Toxicity Equivalence Factor (TEF) relative to
         Benzo(a)pyrene. TEF values are provided in brackets as follows: Benz(a)anthracene (0.1), Chrysene (0.01), Benzo(b+j) & Benzo(k)fluoranthene (0.1), Benzo(a)pyrene (1.0), Indeno(1.2.3.cd)pyrene (0.1),
         Dibenz(a.h)anthracene (1.0), Benzo(g.h.i)perylene (0.01). Less than LOR results for 'TEQ Zero' are treated as zero, for 'TEQ 1/2LOR' are treated as half the reported LOR, and for 'TEQ LOR' are treated as being
         equal to the reported LOR. Note: TEQ 1/2LOR and TEQ LOR will calculate as 0.6mg/Kg and 1.2mg/Kg respectively for samples with non-detects for all of the eight TEQ PAHs.
     l   EP080: Where reported, Total Xylenes is the sum of the reported concentrations of m&p-Xylene and o-Xylene at or above the LOR.
     l   EP068: Where reported, Total Chlordane (sum) is the sum of the reported concentrations of cis-Chlordane and trans-Chlordane at or above the LOR.
     l   EP068: Where reported, Total OCP is the sum of the reported concentrations of all Organochlorine Pesticides at or above LOR.
     l   EP075(SIM): Where reported, Total Cresol is the sum of the reported concentrations of 2-Methylphenol and 3- & 4-Methylphenol at or above the LOR.
     l    Asbestos Identification will be conducted by ALS Melbourne, NATA accreditation no. 825, site no 13778
     l   SPLIT WORK ORDER: It should be noted that ALS has split this work order with the following work order EB2406402 due to the size of the sample numbers. For any further information
         regarding this processing of samples please contact ALS client services division on [email protected]
     l   EG035T (Total Mercury) Sample TP21-0.1 (EB2406372-035) shows poor matrix spike recovery due to sample heterogeneity. Confirmed by visual inspection.
     l   EP066 Polychlorinated Biphenyls (PCB): High surrogate recovery for sample's “TP21-0.5” (EB2406372_036) and “TP34-0.1” (EB2406372_078) deemed acceptable as associated results are less than LOR.
     l   EP080 - TRH Volatiles/BTEX: High LCS recovery deemed acceptable as all associated analyte results are less than LOR
     l   EG005T (Total Metals by ICP-AES): TP21-0.1 (EB2406372-035) shows poor matrix spike recovery due to sample heterogeneity. This has been confirmed by visual inspection.
     l   EP071 – TRH Semivolatile Fraction: Sample 'TP21-0.1’ (EB2406372-035) shows high matrix spike recovery due to sample heterogeneity. Confirmed by visual inspection.
     l   EG005T (Total Metals by ICP-AES): Some samples shows poor matrix spike recovery due to sample heterogeneity. This has been confirmed by visual inspection.
     l   EG005T (Total Metals by ICP-AES): TP18-0.1 (EB2406372-023) shows poor duplicate results due to sample heterogeneity. This has been confirmed by visual inspection.
     l   EP075: Where reported, 'Sum of PAH' is the sum of the USEPA 16 priority PAHs
     l   EA200 'Am'     Amosite (brown asbestos)
     l   EA200 'Cr'     Crocidolite (blue asbestos)
     l   EA200 'Trace' - Asbestos fibres ("Free Fibres") detected by trace analysis per AS4964. The result can be interpreted that the sample contains detectable 'respirable' asbestos fibres
     l   EA200: Asbestos Identification Samples were analysed by Polarised Light Microscopy including dispersion staining.
     l   EA200 Legend
     l   EA200 'Ch'     Chrysotile (white asbestos)
     l   EA200: 'UMF' Unknown Mineral Fibres. "-" indicates fibres detected may or may not be asbestos fibres. Confirmation by alternative techniques is recommended.
