Traditional water sampling approaches have relied on collection of discrete grab samples that represent a single point in time. Despite improvements in technique, such as development of solid-phase extraction, collection of large volumes of water is required to satisfy the detection limit requirements of commonly used analytical methods. In cases where bulk (or filtered) water samples are shipped to the laboratory, the preservation and transport of large volumes of water can be problematic. On...
