15 Method ID Methodology Summary VOC in soil and water by headspace trap GCMS WILAB 7b TRH in soil and water Polycyclic Aromatic Hydrocarbons in soil and water by GCMS GC5 samples are extracted with dichloromethane/acetone and waters with dichloromethane and analysed by GC with dual ECD's. GC6 samples are extracted with dichloromethane/acetone and waters with dichloromethane and analysed by GCECD. Metals in soil and water by ICPOES. WILAB 6 Metals by AAS WILAB 8 Digests WILAB.1 Asbestos Identification: Qualitative identification of asbestos types in bulk samples by Polarised Light Microscopy (PLM), including Dispersion Staining Techniques. Accreditation does not cover the identification of Synthetic Mineral Fibres. Notes: a) If Unknown Mineral Fibres (UMF) are detected by PLM and dispersion staining confirmation by another independent technique may be required. b) Asbestos found to be nonhomogenous within samples is reported as "hand picked".

21 Report Comments: Australian Drinking Water Guidelines recommend that Thermotolerant Coliform & E.coli levels are less than 1cfu/mL. The recommended maximums are taken from "Australian Drinking Water Guidelines", published by NHMRC& ARMC Asbestos was analysed by Approved Identifier: Airborne fibres were analysed by Approved Counter: Joshua Lim Not applicable for this job INS: Insufficient sample for this test; NT: Not tested; : Practical Quantitation Limit; <: Less than; >: Greater than RPD: Relative Percent Difference; NA: Test not required; : Laboratory Control Sample; NR: Not requested NS: Not specified; NEPM: National Environmental Protection Measure Quality Control Definitions : This is the component of the analytical signal which is not derived from the sample but from reagents, glassware etc, can be determined by processing solvents and reagents in exactly the same manner as for samples. Duplicate: This is the complete duplicate analysis of a sample from the process batch. If possible, the sample selected should be one where the analyte concentration is easily measurable. Matrix Spike: A portion of the sample is spiked with a known concentration of target analyte. The purpose of the matrix spike is to monitor the performance of the analytical method used and to determine whether matrix interferences exist. (Laboratory Control Sample): This comprises either a standard reference material or a control matrix (such as a blank sand or water) fortified with analytes representative of the analyte class. It is simply a check sample. Surrogate Spike: Surrogates are known additions to each sample, blank, matrix spike and in a batch, of compounds which are similar to the analyte of interest, however are not expected to be found in real samples. Laboratory Acceptance Criteria Duplicate sample and matrix spik e recoveries may not be reported on smaller jobs, however were analysed at a frequency to meet of exceed NEPM requirements. All samples are tested in batches of 20. The duplicate sample RPD a matrix spik e recoveries for the sample batch were within laboratory acceptance criteria. Duplicates: x any RPD is acceptable; >5x 050 RPD is acceptable. Matrix Spike and : Generally for inorganics/metals; for organics and for SVOC and Speciated Phenols is acceptable. Surrogates: is acceptable for general organics and for SVOC and Speciated Phenols. Page 21 of 21
