AMD Treat 3.0 AMD Abatement Cost-Estimating Tool
AMD Treat is a computer program designed to aid in estimating
Acid Mine Drainage (AMD) pollution abatement costs. AMD
can assist cost estimation profiling for a wide range of
chemical treatments and passive treatment types, including
anaerobic and aerobic wetlands construction, limestone
channels, vertical flow ponds, caustic soda, lime, ammonia,
and other treatment systems. The abatement cost modeling
takes account of more than 500 factors in cleanup cost
estimation, including construction, piping, land purchasing
costs, revegetation, labor, design, sludge remover, and
many more cost components entailed in a comprehensive treatment
project. AMD was developed by the Pennsylvania Department
of Environmental Protection, the West Virginia Department
of Environmental Protection, and the U.S. Office of Surface
Mining Reclamation and Enforcement (OSM). It is available
for free download at http://amd.osmre.gov/amdtreat.htm
Better Assessment Science Integrating Point and Nonpoint
Sources (BASINS) Software System
This environmental analysis program was created for use by
regional, state, and local agencies in performing watershed
and water quality studies. When installed on a personal computer,
BASINS enables users to evaluate water quality at individual
stream locations or throughout a watershed, making possible
rapid assessment of point source and nonpoint source data
in an easily usable format. BASINS is available as a free
download from the U.S. EPA website or can be purchased from
the EPA on three CD-ROMS. Read more about BASINS 3.0 and
download your copy at http://www.epa.gov/waterscience/basins/b3webdwn.htm
National Atlas of the United States
The U.S. Department of the Interior has updated the National
Atlas of the United States, first published in 1970, with
an interactive web page that allows users to access detailed
maps at no cost displaying geospatial and geostatistical
data including soil data, watershed information, political
boundaries, and more. For GIS mapping and a host of other
applications this website can prove invaluable to the watershed
professional. Check the new National Atlas out at www.nationalatlas.gov
Terraserver
Another online mapping service, Terraserver.com was created
as a joint research project with the USGS, Microsoft and
Compaq Computers to provide satellite images and aerial photography
to online subscribers. Terraserver has grown to provide detailed
images from 56 countries, with the aim of world-wide coverage.
Images with resolution of 8 meters detail are available free,
and images with detail down to 1 to 2 meters are available
to subscribers. Get a bird’s eye view of your watershed
projects at www.terraserver.com
