7. Quality Assurance / Quality Control Quality assurance and quality control procedures shall generally be in accordance with those described in the EPA’s (2005b) Manual of Standard Operating Procedures for Environmental Monitoring against the Cockburn Sound Environmental Quality Criteria (2003 - 2004) and ANZECC/ARMCANZ (2000b) Australian Guidelines for Water Quality Monitoring and Reporting, as described below. 7.1. Quality Assurance and Quality Control in Field Sampling An appropriate quality assurance and quality control programme shall commence prior to sampling and continue through to the final reporting stage, including procedures designed to prevent, detect and correct problems in the sampling process and so to characterise errors statistically through quality control samples. As a minimum, it includes being able to adhere to protocols, being able to avoid contaminating samples, and being able to calibrate field instruments and make field observations. 7.1.1. Recording of Field Procedures A complete record of all field procedures will be maintained, including: • Sampling locations (must be relocatable — datum type shall be recorded with location coordinates); • Sampling methods; • Sample handling, preservation, and storage procedures; and, • Dates and times of collection, preservation, and storage. A sample-inventory log and a sample-tracking log will also be maintained. Any circumstances potentially affecting sampling procedures shall be documented. 7.1.2. Non-collection of Field Data While every reasonable effort must be made to undertake the field monitoring program according to the schedule and procedures described in this WQMP, circumstances delaying the collection of data, or in the worst case resulting in the non-collection of data, may include: • Weather conditions causing unsafe sea conditions to work (the skipper of the vessel will be responsible for deciding on whether conditions are safe or not); • Equipment failure or malfunction; or • Accidental loss of samples. Where data cannot reasonably be collected on schedule, then data collection should resume at the first available opportunity or the next scheduled sampling date, whichever comes first. Justified reasons for any delay or non-collection of data shall be included in data reports. 7.1.3. Maintenance and Calibration of Field Equipment All equipment and field instruments shall be kept clean and in good working order, and calibrations and preventative maintenance shall be carried out according to pre-defined schedules and recorded carefully. 7.1.4. Sample Tracking Sample tracking procedures require that metadata, including details of sampling date, time, location, duration, environmental conditions and procedures used for water, mussel and/or sediment collection be recorded. In addition, sample transport information, including chainof-custody (COC) forms and sample receipt notifications shall be completed and forwarded to the relevant parties, including delivery of the samples to sub-consultants for analysis. The original and one copy of the chain-of-custody documentation shall accompany all samples provided to the laboratory and further copies made available for filing as required. There must be a standard chain-of-custody form available for this purpose. The purpose of the form is to clearly identify what samples are included, the treatment that has been/should 32 Oceanica: Fremantle Ports: Inner Harbour and Channel Deepening - Water Quality Monitoring Program
e applied to samples (filtration etc), what analyses are to be performed and by whom, and who has had custody of the samples. This information is to be completely documented on the form, and the forms must accompany the sample container(s). Chain-of-custody must be documented by everyone having responsibility for a set of samples. This should also include couriers, but should that not be possible, the courier’s signature on the waybill is sufficient. The person sending the samples should retain a copy of the form for his or her own records. When the samples reach their destination, the person receiving them must complete the form(s), keep the copy for their records and return the original with the results. 7.1.5. Sample Blanks Sample blanks may be used to estimate the levels of contamination that are incurred during any stage of field sampling activities. Field blanks may be used to estimate the contamination caused by sample collection, filtering, containers, equipment and transport. When used, blanks can be particularly useful in identifying problems with specific components of the monitoring procedure, which can then be quickly rectified. The reliability of the sampling procedure (and field officer) may also be ascertained by incorporating field blanks into the monitoring programme. Further explanations on the use of different field blanks are provided by ANZECC & ARMCANZ (2000b). 7.1.6. Duplicates and Replicates Duplicate samples are obtained by dividing a collected sample into two or more subsamples. Duplicates can be useful for revealing the size of errors from contamination that is occurring between sampling and sample analysis. Ideally, one duplicate should be obtained for about every 10 samples. Replicate samples are two or more samples that are collected simultaneously to establish the reproducibility of sampling. Ideally, three samples are required to enable testing of interand intra-laboratory accuracy and precision. Duplicate and replicate samples may be used as back-up samples to confirm whether a trigger has been exceeded and are particularly useful in situations when field collection is a difficult or costly exercise. 7.2. Quality Assurance and Quality Control in Laboratory Procedures Only laboratories accredited with the National Association of Testing Authorities (NATA) shall be utilised to undertake sample analyses. 7.2.1. Traceability of Results Apart from its chain of custody details for each sample, the laboratory must include the following information for each analysis: • Identity of sample analysed; • Identity of analyst; • Name of equipment used; • Original data and calculations; • Identification of manual data transfers; • Documentation of standard preparation; and, • Use of certified calibration solutions. 3.4.2 Laboratory Data Reporting Laboratory reports shall be provided as part of the monitoring programme, including: • The laboratory name and address; • Tabulation of samples and analysis data; • Identification of the analytical methods used; • Limit of Reporting (LOR); • Confidence intervals of the analytical results; Oceanica: Fremantle Ports: Inner Harbour and Channel Deepening - Water Quality Monitoring Program 33
