Preliminary Site Investigation at63 North Pde, Mt Druitt NSW A. D. Envirotech Australia Pty LtdLaboratory blank resultsThe assessment of blank analysis results was carried out in order to determine the existence andmagnitude of contamination resulting from laboratory activities. No contaminants were found inthe blanks analysed by the laboratory.Instrument detection limitsMethod detection limitsMatrix or practical quantification limitsThe smallest amount of a substance that can be detected by GAL above the noise in a procedureand within a stated confidence level is the detection limit. Current practice identifies severaldetection limits. These are the instrument detection limit (IDL), the lower level detection (LLD),the method detection limit (MDL) and the practical quantitation limit (PQL).The relationship among these levels is approximately IDL : LLD : MDL : PQL = 1 : 2 : 4 : 10.Refer to Appendix IX for the list of PQLs provided by EL. When dilution of a sample is involvedin the sample preparation, the method detection limit is adjusted by the dilution factor.Blind replicate samplesOne blind replicate sample was collected to determine the variability of the sampling process.Samples are collected simultaneously from the same source and under identical conditions as theoriginal sample.Australian Standard 4482.1 specifies the typical RPD values for blind replicate samples to be30% - 50%. Combining the AS acceptance criteria with the recommendations of the USEPAmethodology, the control limits described below were used.1. A control limit of 50% for the RPD for original and blind replicate sample values greaterthan or equal to 5x the Detection Limit (DL),2. A control limit of ± the DL if either the sample or duplicate value is less than 5x the DL.3. If both samples values are less than the DL, the RPD is not calculated 12 .The table below represents the Relative Percent Difference (RPD) values for the original andblind replicate samples collected during the investigation. Where condition 2 or 3 was applicable,an estimated level of agreement between the results was provided and, where appropriate, anRPD value calculated.The blind replicate sample collected on the same day exhibited a reasonable level ofreproducibility (RPD < 50%) for all analytes, excluding zinc. The sample exhibited the LowLevel of Agreement for zinc. Considering that zinc in soils did not yield concentrations above theacceptance criteria, it is the author‟s opinion that the EnviroLab result can be accepted and,therefore, no further investigation of soil with regard to zinc is warranted.Analysis of split samples showed 15 valid values and 1 invalid values (refer to Table 10).4224 63 North Pde Mt Druitt PSI.v1 final Page 43
