Download Link: http://data.nconemap.gov/downloads/vector/awqms.zip
Abstract: The North Carolina Department of Environment and Natural Resources, Division of Water Quality, in cooperation with the NC Center for Geographic Information and Analysis, developed the GIS data set, Ambient Water Quality Monitoring Sites data to enhance planning, siting, and impact analysis in areas directly affecting water quality. This file identifies locations in North Carolina where water quality data are collected on a routine basis and analyzed for presence of various chemicals.
Purpose: This data was created to assist governmental agencies and others in making resource management decisions through use of a Geographic Information System (GIS).
Supplemental Information: > >Revisions and updates to this layer include: >4.) filename: awqms307 Regular update. May 14, 2007. >3.) filename: awqms900 The September 30 2000 update consisted of >CGIA receiving from DWQ an EXCEL spreadsheet that listed active >ambient water quality monitoring stations. This database contained >corrections to many of the sites from the original database. >Additionally, many stations were moved, discontinued, or added since >the original database. NC Division of Water Quality has changed the >process by which station locations are mapped. With the submission >of this new data the layer is longer considered unverified. >2.) filename: uvawqms1298 The December 1998 update to this layer >consisted of projecting the data from NAD27 datum, State Plane >projection, units of measure feet TO: NAD83 DATUM, State Plane >PROJECTION, UNITS OF MEASURE METERS. This was >done to comply with the NC Geographic Information Coordinating Council's >"Statement of Direction for North Carolina Corporate Geographic Database >Horizontal Reference, Datum and Unit of Measure". This reprojecting was >done in various ways depending on the data type and content. Vector >data was projected using the 'project' command in ESRI's Arc software >and topology was cleaned and built based on coverage needs. Raster >data was projected using ESRI's Grid module and various steps as >applicable. >1.) uvawqms794 - This July 11, 1994 version represents the original >version of this data. There was a file from March of 1991 which >contained a point improperly placed. This 7/11/94 version corrected >that location and the old version was deleted. This file is >considered unverified (UV).
