For the investigation and monitoring of groundwater, appropriate sampling methods should be selected according to the conditions of the survey site and the purpose of the investigation and strictly follow the sampling operation procedures in order to obtain real and representative samples. On the basis of sorting out the common ground water sampling methods and sampling apparatus, this paper introduces the compiling process of the industry standard "groundwater sampling technique regulation" and the main contents. The regulation content involves sample collection requirements, sampling methods, samples storage and quality control of groundwater field test samples, inorganic and organic test samples, gas test samples, isotope test samples and the specific samples such as geothermal water and drinking mineral water samples.
