     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   ALS is not NATA accredited for the analysis of Exchangeable Aluminium and Exchange Acidity in soils when performed under ALS Method ED005.
     l   ALS is not NATA accredited for the analysis of Exchangeable Cations on Alkaline Soils when performed under ALS Method ED006.
     l   EA200: Asbestos Identification Samples were analysed by Polarised Light Microscopy including dispersion staining.
     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   EA200 Legend
     l   EA200 'Am'     Amosite (brown asbestos)
     l   EA200 'Cr'     Crocidolite (blue asbestos)
     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.
     l   EA200: Analysis of asbestos from swabs and tapes is not covered under the current scope of NATA accreditation.
     l   ED007 (Exchangeable Cations): Unable to calculate Magnesium/Potassium Ratio result as required Exchangeable Potassium results are less than the limit of reporting.
     l   EG005T (Total Metals by ICP-AES): EB2305781-001 shows poor duplicate results due to sample heterogeneity. This has been confirmed by visual inspection.
     l   EG005T (Total Metals by ICP-AES): EB2305781-003 shows poor matrix spike recovery due to sample heterogeneity. This has been confirmed by visual inspection.
     l   EG005T (Total Metals by ICP-AES): EB2305781-017 shows poor duplicate results due to sample heterogeneity. This has been confirmed by visual inspection.
     l   EG005T (Total Metals by ICP-AES): TP6-0.1 (EB2306000-016) shows poor matrix spike recovery due to sample heterogeneity. This has been confirmed by visual inspection.
     l   EG005T (Total Metals by ICP-AES): TP11-0.1 (EB2306000-028) shows poor duplicate results due to sample heterogeneity. This has been confirmed by visual inspection.
     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: For samples larger than 30g, the <2mm fraction may be sub-sampled prior to trace analysis as outlined in ISO23909:2008(E) Sect 6.3.2-2
     l   ED007 and ED008: When Exchangeable Al is reported from these methods, it should be noted that Rayment & Lyons (2011) suggests Exchange Acidity by 1M KCl - Method 15G1 (ED005) is a more suitable method
         for the determination of exchange acidity (H+ + Al3+).
     l   EA200: 'Yes' - Asbestos detected by polarised light microscopy including dispersion staining.
     l   EA200: 'No*' - No asbestos found, at the reporting limit of 0.1g/kg, by polarised light microscopy including dispersion staining. Asbestos material was detected and positively identified at concentrations estimated to
         be below 0.1g/kg.
     l   EA200: 'No' - No asbestos found at the reporting limit 0.1g/kg, by polarised light microscopy including dispersion staining.
