Groundwater quality control analyses

Trick J. K., Stuart M., and Reeder S. describe the tools available to the field sampler for the collection of groundwater samples, methods of on-site water quality analysis, and the appropriate preservation and handling ofsamples. The authors discuss the merits of different purge methodologies and show how on-site measurements such as pH, specific electrical conductance (SEC), oxidation—reduction potential (ORP), dissolved oxygen (DO), temperature, and alkalinity can be used to provide a check on subsequent laboratory analyses. Techniques for the preservation and analysis of samples and quality assurance and quality control are also presented. 

This book series will ensure a wide coverage of issues related to water quality measurements, including the topics of the above mentioned courses and the outcome of recent scientific advances. In addition, other aspects related to quality control tools (e.g. certified reference materials for the quality control of water analysis) and monitoring of various types of waters (river, wastewater, groundwater) will also be considered. 

Because hydrogeological systems, and hence groundwater bodies, are complex and often hard to monitor, it is difficult to establish formal quality control criteria for the whole programme. It is therefore recommended to establish criteria for each stage of the process as part of a quality plan. Certain elements are well controlled, e.g. sample handling, laboratory analysis and data management, but others, such as conceptual...
