Provides general principles to be applied in the design of sampling programs, general guidance on sampling techniques and guidance on the procedures to be taken to preserve and transport samples for the physical, chemical and radiological analysis of waters and wastewaters, including bottom sediment and sludges, for the purposes of process control, quality characterization, identification of sources of pollution, compliance with water quality guidelines or standards, and other specific reasons.

This Standard provides general principles to be applied in sampling for the physical, chemical, microbiological or radiological analysis of waters and waste waters, including bottom sediment and sludges, for the purposes of process control, quality characterization, identification of sources of pollution and the monitoring of background levels.The guidance on sampling procedures provided in this Standard is generally applicable. Where alternative procedures are used they are to be demonstrated to be at least as reliable as those provided in this Standard or that they will achieve the objectives of the sampling and analysis program.The general principles and guidance contained in this Standard are as follows:(a) General principles to be applied in the design of sampling programs.(b) General guidance on sampling techniques.(c) General guidelines on the procedures to be followed to preserve and transport samples. These include guidelines for the selection of containers, quality control measures and tables that provide details of preservation techniques.NOTE: Special care is needed when collecting samples for microbiological examination. Recommendations for the selection and preparation of sample containers and transport and storage of microbiological samples is provided in AS 2031.2.
