Description: This dataset depicts sites contained in the DEQ's Hazardous Waste (HazWaste) information database. HazWaste contains information on Oregon hazardous waste generators, treatment, storage, disposal and recycling operations as reported on Oregon HW Reporting Forms.
Description: This point layer includes Oregon Department of Environmental Quality (DEQ) and Oregon Department of Human Services' (DHS) Drinking Water Program potential contaminant sources (PCSs) identified in Source Water Assessments for community (C) and non-transient non-community (NTNC) public water systems (PWS) that were active in June 1999 (when Oregon's Source Water Assessment Plan was approved by EPA). These potential contaminant source threats are to be used in conjunction with the mapped sensitive areas to provide an overall picture of the susceptibility of the drinking water system. Data is available on-line at "http://www.deq.state.or.us/wq/dwp/dwpswaresults.htm".
Copyright Text: The GIS data layer of identified potential contaminant sources was developed by Oregon Dept. of Environmental Quality/Water Quality Division/Drinking Water Protection Program. PCS locations were generated using topographic maps and/or aerial photographs; PCS locations were not verified with GPS methods.
Description: This feature class identifies structural faults located within Oregon. Features within this dataset are represented as vector lines. This geodatabase contains cartographic representations for line symbols from Section 2 of FGDC Digital Cartographic Standard for Geologic Map Symbolization (FGDC Document Number FGDC-STD-013-2006). Please see the Esri geologic mapping template for more details and instructions for using cartographic representations with fault lines.

Description: This data set contains locations and information on faults and associated folds in the United States that are believed to be sources of M>6 earthquakes during the Quaternary (the past 1,600,000 years). On the website, maps of these geologic structures are linked to a database containing detailed descriptions and references. The database is intended to be the USGS?s archive for historic and ancient earthquake sources used in current and future probabilistic seismic-hazard analyses. Our website presents for the first time a single source that summarizes important information on paleoseismic (ancient earthquake) parameters. These data are compiled from thousands of journal articles, maps, theses, and other documents, as referenced herein. The database is designed to serve a variety of needs, both in terms of the user community and methods of delivering the data.
Copyright Text: The project coordinator is Michael Machette (USGS). The database structure was created by Kathy Haller (USGS) and an early version of the web interface and search engines were created by Larry Mayer (formerly of the University of Miami at Oxford, Ohio). The GIS data was engineered and maintained by Richard Dart (USGS). The fault and fold traces were digitized mainly by Richard Dart, with help from Dean Hancock*. Static maps were made by Susan Rhea (USGS), Richard Dart, and Damon Sather*. The graphic web browser and ArcIMS module (still under development) were created by Susan Rhea, Damon Sather*, Karen Morgan*, and John Cox*. Much of the reference database and entry of data into the text database was done with the able assistance of Philly Morrow, Meredith Frey, and Kelli Clark (*, all former student interns or contractors to the USGS). Compilers and cooperators are listed on the web page (http://earthquake.usgs.gov/qfaults/contrib.html). Compilers are those who described faults or folds for the database. Cooperators are those who assisted with the development of digital fault data (traces), the database structure, or the geographical information system (GIS) interfaces.
Description: This is preliminary FEMA floodplain data for the State, compiled from various sources and of various ages by the Oregon Department of Land Conservation and Development. It is not finalized, and should not be used as a definitive boundary of 500-year flood waters. It should only be used to provide geographic context to visualize potential flood extent.
Description: This is preliminary FEMA floodplain data for the State, compiled from various sources and of various ages by the Oregon Department of Land Conservation and Development. It is not finalized, and should not be used as a definitive boundary of 100-year flood waters. It should only be used to provide geographic context to visualize potential flood extent.
