# va_loaddata.rdb (tab-delimited ASCII file ) # Date created: 9/3/1998 # # Water-quality load data for sites in Virginia # # This file contains estimated loads for nontidal sampling sites # sites where major forms of nutrient (nitrogen and phosphorus) and # sediment were sampled. # # The selection of water-quality data from nontidal sites for inclusion # in the database was based on the following minimum criteria (Langland and # others, 1995): # # - Nutrient- and sediment-concentration data collected between # October 1, 1971, through December 31, 1996. # # - A minimum of 12 nutrient- and sediment-concentration samples # representing fall, winter, spring, and summer conditions # collected throughout any consecutive 3-year time span. # # - Nutrient- and sediment-concentration data available in digital format. # # The selection of sites where loads were estimated was based on the following # minimum criteria (Langland and others, 1995): # # - Non-tidal site satisfies minimum criteria for inclusion as a # water-quality site (see above). # # - At least 50 nutrient or sediment samples were collected at the site # over at least 3 years, regardless of the availability of # continuous streamflow data. # # - If water-quality data were collected within 1,500 yards of a # continuous streamflow station, both sites were examined on topographic # maps to determine if the streamflow data were suitable to # estimate loads for the water-quality site. # # REFERENCE: Langland, M.J., Lietman, P.L., and Hoffman, S.A., Synthesis of # nutrient and sediment data for watersheds within the # Chesapeake Bay Drainage Basin, 1995, U.S. Geological Survey # Water-Resources Investigations Report 95-4233, p. 6. # # Contacts: Michael J.
