I am assisting the Groundwater Resources Program in using my GIS programs (based on arc macro language or AML) to convert State well log data bases into data sets (point coverages) useful for hydrologic analysis. The programs convert a state’s computerized well log records into a point coverage containing each well’s lithology, water level, well depth, land-surface altitude, screen and casing information, construction date, water use, owner, and specific capacity data (pump rate, pumping time, and resulting drawdown) whenever available. The greatest value from this effort comes from converting a driller’s lithologic description, which follows no particular protocol, into standardized USGS lithologic codes. Then those lithologic codes are further defined into either coarse or fine grained deposits. This effort unlocks a vast geologic data source that was previously unavailable for hydrologists interested in:
1. Measuring the total thickness of sand and gravel deposits in the glacial deposits or the total thickness in any given interval of the glacial deposits
2. Estimating horizontal and vertical hydraulic conductivity, as well as transmissivity
3. Visualizing in three dimensions the extent of aquifers and confining units
4. Obtaining input for horizontal and vertical hydraulic conductivity for groundwater models
5. Assessing groundwater vulnerability through measuring the total fine-grain deposits above a water-supply well screen
6. Calculating low-flow and recharge statistics from the measurement and position of sand and gravel content in the glacial deposits
7. Water-level data points
8. Water use information
Through use of the AML’s, the project is producing state-wide GIS grids of:
1. Average horizontal hydraulic conductivity of the glacial deposits based on percent of coarse-grained deposits
2. Average vertical hydraulic conductivity of the glacial deposits based on the distribution of coarse- and fine-grained deposits
3. Total transmissivity of the glacial deposits based on an assumed value of 100 ft/d for sand and gravel hydraulic conductivity
4. Total sand and gravel thickness within the glacial deposits
5. Thickness of the glacial deposits
6. Actual hydraulic conductivity and transmissivity based on specific capacity data from the well logs
7. Bedrock surface altitude
In addition to the grids, the AML’s generate a State-wide figure of the location of large pumpages and a zip file that contains the necessary data sets and programming to generate geologic cross sections for any area in the State.
The data sets generated have already been used by the National Cancer Institute and by groundwater modelers in the NAWQA program and in the Willison Basin project that extends through Montana, North Dakota, and Canada. The data has been considered so valuable to NAWQA goals that the NAWQA program has given the Indiana office funds to enter pdf file records of well logs into computerized text files that can be processed into the point coverages for their vulnerability analysis and computer modeling. The grids are also being used by the Indiana office in an innovative manner to help predict low-flow statistics at ungagged sites in Indiana. We are currently looking for an opportunity to use the grids to help predict recharge rates and recharge rate recurrence intervals for a State.

For the AGU Fall 2012 Meeting, the following session was organized. The session recognized the significance of long-term research conducted by USGS and university colleague in flow and transport influenced by groundwater-surface water connections.
Session:
Groundwater-Surface Water Interactions: Three Decades of Transient Storage Analysis to Understand River Transport and Watershed Connection
Conveners:
Adam S Ward, University of Iowa; Judson W Harvey, USGS; Roy Haggerty, Oregon State University
Description:
"Bencala & Walters' Simulation of solute transport in a mountain pool-and-riffle stream: A transient storage model (1983) has been cited 320 times, making it one of the most referenced Water Resources Research papers (99.5th percentile). This work is largely responsible recognizing transient storage as an important hydrological phenomenon in streams and helped to launch collaborations between ecologists and hydrologists. We invite contributions on developments in measurement of transient storage (via tracers or pairing with other techniques), new applications of the transient storage concept, and new ideas for modeling transient storage.
The Invited Abstract of Aaron I Packard, Northwestern University, reflects upon the significance:
Reflections on solute transport in rivers: Historical developments, present approaches, and future promise.
Thirty years after Bencala and Walters’ landmark paper on transient storage seems like a good time to reflect on our understanding of hyporheic exchange and solute transport in rivers. Bencala and Walters’ work, and the related fieldwork of many others at the U.S. Geological Survey, changed the paradigm for flow in river corridors. Previously, the prevailing view had been that in-stream transport was regulated primarily by advection and dispersion. This thinking was rooted in well-established theory derived from the work of G.I. Taylor on dispersion processes, and supported by extensive fieldwork in the 1960’s and 1970’s. River and groundwater flow were strictly separated at the channel boundary. After Bencala and Walters (and a lot of follow-up work!) we now understand that water continuously exchanges across stream channel boundaries. This has profound implications for not only solute transport in rivers, but also a wide variety of biogeochemical, ecological, and even geomorphological processes. In this talk, I will review the historical development of theory for solute transport in rivers, try to convey why Bencala and Walters was so important to both hydrology and biogeochemistry, and discuss how recent developments in measurement methods and stochastic transport theory can be used to further advance our understanding of surface-groundwater connectivity.

The only committee that I am now participating in is the Missouri River Basin Interagency Roundtable's Sediment Management Workgroup. We try to find sediment objectives for the Missouri River that the USACE, USFWS, USEPA, and the NPS can agree to. Not sure if it counts, but I am also on the Board of the Missouri Prairie Foundation. I'm not in an official mentorship program, but continue to consult with MWSC management (mostly Kansas City Office) on various issues - both new and old.

Taken over administration and indexing of four mineral resources archives:
· the Latin American Archive consisting of 55 feet of files, 61 feet of books and journals, and 39 drawers of maps,
· the Art Daily Placer collection, 25 feet of files on placer mineral deposits world-wide;
· 3) the Union Carbide Data Archive, 68 feet of files on tungsten deposits and exploration and 27 feet of phosphate. There is no index, and Jim has started to compile this.
· 4) The Dan Mosier Modeling Data Archive, an index of mineral deposits worldwide that needs to be indexed.

· I retired and went on Emeritus status at the beginning of 2011. I spent the first year and a half helping to finish the USGS global mineral resource assessment for undiscovered porphyry copper deposits. Since then I've been working on a lithotectonic database and derivative maps of the northern Rocky Mountain region and a geologic map of the Blackbird Co-Cu mine area (where I once worked on mineral resources of the Salmon National Forest). Based on that work, I led a field trip of the Idaho cobalt belt for the Tobacco Root Geological Society and the Belt Association in late July-early August of 2013.
· While working on the Blackbird map, I mentored my field assistant, Shane Koski, an undergraduate intern from Eastern Washington University, who is now applying to graduate schools with the intention to get a PhD in geology.
· This year, I have been helping Niki Winzer, a young USGS geologist, get started on a structural geologic study of the Yellowpine Au-Sb-W deposit in the Payette National Forest, where I once did a mineral-resource assessment project.
· On June 3-4, I will lead 2-days of morning and afternoon field sessions for grade-school students, showing them geologic features in the Dishman Hills urban forest in Spokane, WA.
· On June 10, I will lead a field trip of the Coeur d'Alene drainage basin, downstream from the Coeur d'Alene Pb-Zn-Ag district. This trip is for environmental geology students from Richard Stockton College (NJ). I will show them results of previous USGS work on the character and distribution metals-contaminated sediments in the Coeur d'Alene River valley.
· On Aug. 3-10, I will help Steve Ludington and Niki Winzer run a week-long field trip for visiting Chinese geologists. We will visit the Yellowpine mine, the Blackbird Co-Cu deposit, and the Bingham porphyry Cu mine.
· I continue to attend (and represent USGS) at meetings of the Geological Society of America, the Tobacco Root Geological Society (for studies of the northern Rocky Mountain region), the Belt Association (for studies of the Belt-Purcell basin), the Columbia Basin Geological Society, the local chapter of AIME, and the Ice-Age Floods Institute.

Mentorships:
During this calendar year I have been contributing research advice and laboratory assistance to two post-docs who have been using the mercury analysis instrumentation at the USGS Woods Hole Coastal and Marine Science Center. A rewarding exchange of information concerning mercury research has been with Dr. Pryia Ganguli, (Postdoctoral Scholar, Department of Chemistry and Geochemistry, Woods Hole Oceanographic Institution) and Dr. Anjali Kumar, (Postdoctoral Associate in Biology, Massachusetts Institute of Technology).
In March 2013, I provided training and the loan of the USGS Hydraulically Damped Gravity Corer to Dr. Linda Kalnejais, Assistant Professor, Department of Earth Sciences, University of New Hampshire. Dr. Kalnejais requested this assistance in order to collect undisturbed sediment cores from Massachusetts Bay.
Similar assistance was given to Dr. Timothy Kenna, Associate Research Professor, Lamont–Doherty Earth Observatory, Columbia University, who needed to collect undisturbed sediment cores from Long Island Sound in June 2013.
