Eric Reichard
Biography
Eric Reichard is the Director of the U.S. Geological Survey California Water Science Center (USGS-CAWSC). The USGS-CAWSC, which partners with state, local, and federal agencies, provides impartial hydrologic data and scientific analyses to address California’s water issues.
Prior to assuming his current position in 2009, Reichard served as a Program Chief and Research Hydrologist for the USGS. He has led projects addressing a variety of hydrologic issues, including groundwater – surface-water management and seawater intrusion. He received a B.A. in Economics from the University of Rochester, and an M.S. and a Ph.D. in Hydrogeology from Stanford University.

Assessment of regional management strategies for controlling seawater intrusion
Simulation-optimization methods, applied with adequate sensitivity tests, can provide useful quantitative guidance for controlling seawater intrusion. This is demonstrated in an application to the West Coast Basin of coastal Los Angeles that considers two management options for improving hydraulic control of seawater intrusion: increased injection...

Ground-water quality of coastal aquifer systems in the West Coast Basin, Los Angeles County, California, 1999-2002
The extensive use of ground water throughout the Central and West Coast Basins of Los Angeles County during the first half of the 20th century resulted in declining water levels, widespread seawater intrusion, and deterioration of water quality along most reaches of the coast. In order to control seawater intrusion in the West Coast Basin,...
Land, Michael; Reichard, Eric G.; Crawford, Steven M.; Everett, Rhett R.; Newhouse, Mark W.; Williams, Colin F. Evaluation of tracer tests completed in 1999 and 2000 on the upper Santa Clara River, Los Angeles and Ventura Counties, California
The interaction of surface water and hyporheic water along the Santa Clara River in Los Angeles and Ventura Counties, California, was evaluated by conducting tracer tests and analyzing water-quality data under different flow conditions in October 1999 and May 2000. Tracer and water-quality samples were collected at multiple river and hyporheic...
Cox, Marisa H.; Mendez, Gregory O.; Kratzer, Charles R.; Reichard, Eric G. Geohydrology, Geochemistry, and Ground-Water Simulation-Optimization of the Central and West Coast Basins, Los Angeles County, California
Historical ground-water development of the Central and West Coast Basins in Los Angeles County, California through the first half of the 20th century caused large water-level declines and induced seawater intrusion. Because of this, the basins were adjudicated and numerous ground-water management activities were implemented, including increased...

The access of almost all 270 million U.S. residents to reliable, safe drinking water distinguishes the United States in the twentieth century from that of the nineteenth century. The United States is a relatively water-abundant country with moderate population growth; nonetheless, current trends are sufficient to strain water resources over time,...

Evaluation of surface-water/ground-water interactions in the Santa Clara River Valley, Ventura County, California
The interactions of surface water and ground water along the Santa Clara River in Ventura County, California, were evaluated by analyzing river-discharge and water-quality data and geohydrologic information collected by the U.S. Geological Survey between 1993 and 1995 for the Piru, Fillmore, and Santa Paula subbasins. Measurements of discharge and...
Reichard, Eric George; Crawford, Steven M.; Paybins, Katherine S.; Martin, Peter; Land, Michael; Nishikawa, Tracy Management of groundwater supply and water quality in the Los Angeles Basin, California
Water use and water needs in the coastal Los Angeles Basin in California have been very closely tied to the development of the region during the last 150 years. The first water wells were drilled in the mid-1800s. Currently about 40% of the water supply (9.4 m3 s-1) in the region is provided by groundwater. Other sources of water supply include...
Reichard, E.G.; Crawford, S.M.; Land, M.T.; Paybins, K.S. Numerical model of a tracer test on the Santa Clara River, Ventura County, California
To better understand the flow processes, solute-transport processes, and ground-water/surface-water interactions on the Santa Clara River in Ventura County, California, a 24-hour fluorescent-dye tracer study was performed under steady-state flow conditions on a 45-km reach of the river. The study reach includes perennial (uppermost and lowermost)...

Statistical analysis and mathematical modeling of a tracer test on the Santa Clara River, Ventura County, California
To better understand flow processes, solute-transport processes, and ground-water/surface-water interactions on the Santa Clara River in Ventura County, California, a 24-hour fluorescent-dye tracer study was performed under steady-state flow conditions on a 28-mile reach of the river. The study reach includes perennial (uppermost and lowermost)...

Izbicki, John A.; Reichard, Eric G.; Nishikawa, Tracy; Martin, Peter Implications of uncertainty in exposure assessment for groundwater contamination
Decision-making on regulation, mitigation, and treatment of drinking water contamination depends, in part, on estimates of human exposure. Assessment of past, present and potential future exposure levels requires quantitative characterization of the contaminant sources, the transport of contaminants and the level of actual human exposure to the...
