Acidic Surface Waters of the Conterminous United States GIS Data for the EPA Clean Air Mapping and Analysis Program (C-MAP)

Entry ID: A_Water_EPA

[ Update this Record ]

Summary

Abstract: This coverage contains information about estimates of current
acid-base status of surface waters in National Surface Water Survey
regions in the conterminous U.S., as reported in the National Acid
Precipitation Assessment Program's 1990 Integrated Assessment Report
(NAPAP, 1991). It was created by the Environmental Protection Agency's
Clean Air Markets Division (CAMD) for use with their GIS in ...

Quality Some of these boundaries may not precisely match the acidic surface
water locations, but they are adequate for national-level
analyses. Use of this dataset in smaller scale analyses is not
advised.

This coverage was created using information from Figure 2.2-4 in the
National Acid Precipitation Assessment Program's 1990 Integrated
Assessment Report by digitizing the boundary areas for the Acidic
Surface Waters. The information was incorporated into a .dbf file,
converted to a coverage and projected using ArcInfo 8.0.2.

Access Constraints None

Use Constraints Not all of the acidic surface water areas may precisely match the
actual locations due to the fact that the data was digitized from a
scanned image, but they are adequate for national-level analyses. Use
of this dataset in smaller scale analyses is not advised.
