If you do not accept the policies above and continue to use this website you have been deemed to have accepted. Proper sampling procedures are a vital first step in ensuring monitoring results are representative of a given discharge.
All sampling should be carried out by 5676-3 staff that is trained in relevant sampling and preservation procedures. When both the competent authority and the licensee are sampling at the same time, aqueous samples should be split. This will eliminate the introduction in sample variability when comparing 5667-3.
It is important that sample collection ensures the following criteria are met.
ISO : Water quality — Sampling — Part 3: Preservation and handling of water samples
Many licences require ambient monitoring of groundwater in order to demonstrate no environmental impact from processes and discharges onsite. Groundwater sampling requires specialised training and licensees should ensure it is only undertaken by appropriately qualified and trained personnel in accordance with recognised standards. This standard provides guidance on the techniques necessary to obtain samples for the purposes of quality control and characterisation.
This standard provides guidance on the precautions to be taken to preserve and transport waster samples.
This standard is especially appropriate when grab or composite samples cannot be analysed on-site and have to be transported to an offsite subcontracted laboratory for analysis. This standard contains details on the sampling of iiso waste water. This standard contains details on the design of the groundwater sampling programmes, sampling techniques and handling of water samples.

Sampling Proper sampling procedures are a vital first step in ensuring monitoring results are representative of a given discharge. It is important that sample collection ensures the following criteria are met; All sample collection sheets record whether samples are grab or composite and the time frame over which the composite was collected. This is necessary as the interpretation of results, to demonstrate compliance, varies depending on whether the sample is a composite or grab typically Condition 4 of licences provides details on interpretation.
Sample containers are clean and of an appropriate quality and type. Different analysis requires different container types in order to ensure the integrity of the sample e. Sample location is carefully selected so that a reliable assessment of environmental compliance with ELVs can be made. Samples are kept cool during the period from collection to analysis.
Where necessary, when analysis cannot be conducted is the recommended timeframe, by internationally accepted standards, samples should be appropriately preserved. Chain of custody documentation is maintained. This is extremely important especially where analysis is sub contracted to an offsite laboratory, to ensure that all monitoring results are fully traceable.
