Evaluation of factors that influence estimated zones of transport for six municipal wells in Clark County, Washington
A ground-water flow model was used in conjunction with particle tracking to estimate zones of transport for six municipal well sites in Clark County, Washington. A zone of transport for a well is a three-dimensional volume within a ground-water system that contains all of the ground water that will discharge from that well within a specified time period. All of the zones of transport for a well co

Mississippi Basin Carbon Project; upland soil database for sites in Yazoo Basin, northern Mississippi
The conversion of land from its native state to an agricultural use commonly results in a significant loss of soil carbon (Mann, 1985; Davidson and Ackerman, 1993). Globally, this loss is estimated to account for as much as 1/3 of the net CO2 emissions for the period of 1850 to 1980 (Houghton et al, 1983). Roughly 20 to 40 percent of original soil carbon is estimated to be lost as CO2 as a result

Physical stratigraphy, paleontology, and magnetostratigraphy of the USGS-Santee Coastal Reserve core (CHN-803), Charleston County, South Carolina
The Santee Coastal Reserve core, a 545-ft-deep corehole in northeastern Charleston County, South Carolina, recovered sediments of Late Cretaceous, Paleocene, Eocene, and Quaternary age. The deepest sediments, the Donoho Creek Formation (545-475.7 ft), consist of 69.3 ft of muddy calcareous sand of marine origin. This formation is placed within the upper Campanian calcareous nannofossil Subzone CC

Susceptibility of ground water to surface and shallow sources of contamination, Orange County, North Carolina
In 1998, the relative susceptibility of ground water in Orange County, North Carolina,to contamination from surface and shallow sources was evaluated. A geographic information system was used to build three county-wide layers--soil permeability, land use/land cover, and land-surface slope. The harmonic mean permeability of soil layers was used to estimate a location's capacity to transmit water th

Stream channel cross sections for a reach of the Boise River in Ada County, Idaho
The Federal Emergency Management Agency produces maps of areas that are likely to be inundated during major floods, usually the 100-year, or 1-percent probability, flood. The maps, called Flood Insurance Rate Maps, are used to determine flood insurance rates for homes, businesses, or other structures located in flood-prone areas. State and local governments also use these maps for help with, among

Summary of ground-water data for Tutuila and Aunuu, American Samoa, for October 1987 through September 1997
Ground-water and rainfall data for the period October 1987 through September 1997 from Tutuila and Aunuu, American Samoa, are plotted in time-series graphs and summarized. The data include pumpage and chloride concentrations from 53 production wells on Tutuila, including 5 new wells that were put into production between October 1996 and September 1997, 3 production wells on Aunuu, water-level meas

Ground-water conditions in Georgia, 1998
Ground-water conditions in Georgia during 1998 and for the period of record were evaluated using data from U.S. Geological Survey ground-water-level and ground-water-quality monitoring networks. Data for 1998 included in this report are from continuous water-level records from 130 wells and chloride analyses from 14 wells. Data from one well is incomplete because data collection was discontinued.
