This raster depicts the percentage of lithological the hydraulic conductivity (in micrometers per second) of surface or near surface geology. We derived these rasters by calculating the average conductivity for each map unit in combined surficial-bedrock geologic maps. We used state geologic maps (Preliminary Integrated Geologic Map Databases for the United States, Open File Reports 2004-1355, 2005-1305, 2005-1323, 2005-1324, 2005-1325, 2005-1351, and 2006-1272), which depict surficial geology instead of bedrock when the surficial layers are sufficiently deep. For the state maps that do not incorporate surficial geology (i.e., midwestern states), we overlaid surficial geologic map units with thicknesses greater...

The Water Resources Data System is a clearinghouse of hydrological and climatological data for the State of Wyoming. Land Slide data can be downloaded on a County basis via this interface.
This workbook summarizes geophysical data for each lithology contained within the USGS Preliminary Integrated Geologic Map Databases for the United States (Open File Reports 2004-1355, 2005-1305, 2005-1323, 2005-1324, 2005-1325, 2005-1351, and 2006-1272). The summarized geophysical data contained in the “Lith Summary” spreadsheet (tab) is used to translate lithologies in state geologic maps into maps of continuous physical characteristics (see Geochemical and Geophysical Characteristics of the Conterminous United States, http://dx.doi.org/10.5066/F7X0653P). Full details of the data are provided in the “ReadMe” spreadsheet at the beginning of the workbook.

This raster depicts the percentage of lithological the compressive strength, measured as uniaxial compressive strength (in megaPascals, MPa) of surface or near surface geology. We derived these rasters by calculating the average strength for each map unit in combined surficial-bedrock geologic maps. We used state geologic maps (Preliminary Integrated Geologic Map Databases for the United States, Open File Reports 2004-1355, 2005-1305, 2005-1323, 2005-1324, 2005-1325, 2005-1351, and 2006-1272), which depict surficial geology instead of bedrock when the surficial layers are sufficiently deep.

This web site is provided by the United States Geological Survey's (USGS) Earthquake Hazards Program as part of our effort to reduce earthquake hazard in the United States. We are part of the USGS Geologic Discipline and are the USGS component of the congressionally established, multi-agency National Earthquake Hazards Reduction Program (NEHRP). The USGS participates in the NEHRP with the Federal Emergency Management Agency (FEMA), the National Institute of Standards and Technology (NIST), and the National Science Foundation (NSF). In the 2004 reauthorization of NEHRP by Congress, NIST has been given the lead role to plan and coordinate this national effort to mitigate earthquake losses by developing and applying...

Time series electromagnetic induction-log (TSEMIL) datasets are collected from polyvinyl chloride (PVC) cased or uncased monitoring wells to evaluate changes in water conductivity over time. TSEMIL datasets consist of a series of individual electromagnetic induction logs collected at a frequency of months or years that have been compiled into a dataset by eliminating small uniform offsets in bulk conductivity between logs likely caused by minor variations in calibration. At depths where water conductivity is not changing through time, each log is typically within about ±15 mS/m of the median of the dataset at any given depth, which is within the stated repeatability specifications of the probe (Mount Sopris Instrument...

The salinity of groundwater at the Florida Power & Light Company (FPL) Turkey Point Nuclear Plant in southeastern Florida is being evaluated. The power plant contains a large cooling canal system with warm water; which has salinities elevated above typical, natural surface water in southeastern Florida, circulating within the canals in the uppermost part the highly permeable karst carbonate Biscayne aquifer. The canal system is a closed system that does not discharge directly to fresh or marine surface water bodies. However, exchange between the canal system and groundwater has been postulated based on existing hydrologic information. A pilot study was conducted to determine if Continuous resistivity profiles could...
