Title: EPA Office of Water (OW): 2002 Impaired Waters Baseline NHDPlus Indexed Dataset
Originator: US Environmental Protection Agency, Office of Water
Publication Date: 20100318
Abstract: This dataset consists of geospatial and attribute data identifying the spatial extent of state-reported impaired waters (EPA's Integrated Reporting categories 4a, 4b, 4c and 5)* available in EPA's Reach Address Database (RAD) at the time of extraction. For the 2002 baseline reporting year, EPA compiled state-submitted GIS data to create a seamless and nationally consistent picture of the Nation's impaired waters for measuring progress. EPA's Assessment and TMDL Tracking and Implementation System (ATTAINS) is a national compilation of states' 303(d) listings and TMDL development information, spanning several years of tracking over 40,000 impaired waters.
Purpose: ATTAINS impaired waters data are publicly available online in tabular format (www.epa.gov/waters/ir).
