      abstract = {Surface, ground, and soil-water samples are used to  evaluate the quality of a water system. Surface water can  be sampled easily, ground water can be taken from wells,  but soil water, which is held in the soil pores by strong  forces, cannot be easily removed for analysis. Porous  ceramics, however, enable removing a water sample from  unsaturated soils and subsequent analysis just as surface  water and ground water can be sampled and analyzed.  Sampling soil water instead of, or in addition to, surface  and ground water will often result in a more adequate  description of potential pollution hazards. This report  describes how to use porous ceramic samplers, how to  construct a soil-water sampling system, how and where to  install samplers, and how to obtain samples. It is intended  as a guide for users of porous ceramic samplers who have  little or no background knowledge of soil, hydrology, or  geology.},
