Long-term groundwater monitoring networks can provide essential information for the planning and management of water resources. Budget constraints in water resource management agencies often mean a reduction in the number of observation wells included in a monitoring network. A network design tool, distributed as an R package, was developed to determine which wells to exclude from a monitoring network because they add little or no beneficial information. A kriging-based genetic algorithm method was used to optimize the monitoring network. The algorithm was used to find the set of wells whose removal leads to the smallest increase in the weighted sum of the (1) mean standard error at all nodes in the kriging grid where the water table is estimated, (2) root-mean-squared-error between the measured and estimated water-level elevation at the removed sites, (3) mean standard deviation of measurements across time at the removed sites, and (4) mean measurement error of wells in the reduced network. The solution to the optimization problem (the best wells to retain in the monitoring network) depends on the total number of wells removed; this number is a management decision. The network design tool was applied to optimize two observation well networks monitoring the water table of the eastern Snake River Plain aquifer, Idaho; these networks include the 2008 Federal-State Cooperative water-level monitoring network (Co-op network) with 166 observation wells, and the 2008 U.S. Geological Survey-Idaho National Laboratory water-level monitoring network (USGS-INL network) with 171 wells. Each water-level monitoring network was optimized five times: by removing (1) 10, (2) 20, (3) 40, (4) 60, and (5) 80 observation wells from the original network. An examination of the trade-offs associated with changes in the number of wells to remove indicates that 20 wells can be removed from the Co-op network with a relatively small degradation of the estimated water table map, and 40 wells can be removed from the USGS-INL network before the water table map degradation accelerates. The optimal network designs indicate the robustness of the network design tool. Observation wells were removed from high well-density areas of the network while retaining the spatial pattern of the existing water-table map.

Standing alone as the main authority on the subject, this handbook is the result of a multi-million dollar investigation into groundwater monitoring strategies at energy extraction sites. It gives a detailed, step-by-step description of a proven groundwater monitoring methodology which can be used at all potential pollution sites. This methodology, developed by the author and a ``blue ribbon'' team of hydrologists and hydrogeologists from all over the United States, is endorsed by the U.S. Environmental Protection Agency as ``establishing the state-of-the-art used by industry today''. Although site-specific data are provided, the handbook is developed for general application to coal and oil shale development. All sources of potential groundwater contamination from these two energy extraction types are identified as part of the overall monitoring strategy. Sampling methods are presented, including well design, monitor well placement, sample collection methods, sampling frequency, sample preservation and handling, selection and preservation of constituents for monitoring, sample analysis, and interpretation of water quality data. A complete review is provided of drill stem steps, dual packer tests, long term pump tests, and single packer tests. In addition, hydraulic methods, the application of geophysical techniques including temperature, caliper, gamma ray, spinner, radioactive tracer, velocity, sonic, density, electric, and seisviewer logs are presented. The use of a chronological series of steps, each being fully developed and extensively referenced, means that it is particularly easy to follow for the reader wishing to establish a groundwater monitoring program at a coal or oil shale site. One of the great advantages of the handbook is that it is very detailed, with actual data provided. The handbook is a must for consulting engineers, coal and oil development companies, government and private environmental groups, institutes and universities involved in pollution studies. It will also undoubtedly be used to good advantage by teachers and students for many different types of courses including geological engineering, coal and oil shale mining, environmental geology, sanitary engineering, hydrogeology, etc.
