- Studies concerning the movement and fate of organic chemicals, including hazardous substances, in ground water have underscored the need to use boreholes to obtain samples of ground water that are neither contaminated with foreign materials nor diluted with water from other sources. Additionally, the water samples need to be taken in a manner that prevents the escape of volatile substances. The samples need to be kept close to the original state while in shipment to the water quality laboratory and at the laboratory where the water must be removed from the sample holders without the escape of volatiles or reaction with the air. Within the past year the U.S. Geological Survey has identified its needs for data concerning organics in ground water, and established design criteria for the development of prototype samplers. Certain essential sampler design criteria are: The sampler must go down a 5.1-cm (2 in.) diameter well; the practical sampling depth is at least 61 m (200 ft); the sample holder must be flushed before a sample is taken; and the sample must be kept at the same hydrostatic pressure as when collected.
