- Attribute_Label: Dist_Miles
- Attribute_Definition:
-
Distance, in miles, each site was from the Gold King Mine. To estimate this distance, we used the mile markers provided in the interactive map (https://www.epa.gov/goldkingmine/emergency-response-monitoring-data-gold-king-mine-incident) available from EPA's "Emergency Response to August 2015 Release from Gold King Mine" webpage (<http://www2.epa.gov/goldkingmine>) as a starting point. We then used the map's measuring tool to measure the distance the sampling site in question was from the closest mile marker. If the site was downstream of the marker, the measurement was added to the distance indicated by the mile marker. If the site was upstream of the marker the measurement was subtracted from the distance indicated by the mile marker. For Reference sites (i.e. sites not in the path of the Gold King Mine plume), we took the measurement at the confluence of the reference stream (where the sample was located) and the corresponding main stream affected by the release (instead of measuring to the exact location of the site). For this reason, all sites located on the same reference stream, have the same assigned distance from the mine even though the sites are not necessarily close to each other.

- Description:
-
- Purpose:
-
This shapefile was created to map the sampling and monitoring sites being used by federal agencies, states, tribes, and non-profit organizations who were collecting surface water and sediment quality data in response to the Gold King Mine release of August 5, 2015. The shapefile was used to evaluate the environment where the samples were being collected, to understand the relationship between sites, and to approximate the distance each site was from the Gold King Mine. It was also used to create figures.
- Supplemental_Information: EPA-Created
- Abstract:
-
This shapefile consists of locations where surface water and sediment quality data were collected in response to the Gold King Mine release of August 5, 2015. Though it is not a comprehensive list of all the sites that may have been sampled, it contains sites from a variety of data providers including federal agencies, states, tribes, and non-profit organizations. Specifically, it contains the sites for which we were able to obtain surface water and sediment quality data. The sites were sampled between August 5, 2015 and November 5, 2016, with some sites being sampled more often than others. Some sites were only sampled for sediments or only sampled for surface water, while others were sampled for both.

This shapefile includes sites that were sampled anytime between August 5, 2015 and November 5, 2016 in response to the Gold King Mine release of August 5, 2015. It is not a comprehensive list of all the sites that may have been sampled, instead it is a list of the sites that we were able to obtain water quality or sediment quality data for. Sites were sampled with a varying degree of regularity, with some sites being sampled more often than others. Some sites only have sediment quality data associated with them, while others have only surface water quality data. Some sites have both. This is documented in the Media column of the attributes table. The shapefile includes sites for which we did not have horizontal datum information at the time we added the site to the shapefile. The geographic coordinates of those sites were treated as being in the World Geodetic System of 1984 (WGS84) datum. Some sites had no coordinate information at the time of shapefile creation. Their location was determined using ancillary information and their geographic coordinates were generally estimated using the interactive map (https://www.epa.gov/goldkingmine/emergency-response-monitoring-data-gold-king-mine-incident) available from EPA’s “Emergency Response to August 2015 Release from Gold King Mine" webpage (<http://www2.epa.gov/goldkingmine>). This was documented in the Notes column of the attributes table. On occasion, a data provider assigned more than one set of geographic coordinates to a sampling location. In those instances, we picked one of the sets to represent the sampling site. The Descriptio and Notes attributes can contain empty rows.

- Process_Date: 2015-2016
- Process_Description:
-
The initial shapefile was created in 2015 by opening in ArcMap the Excel table that contained the first group of sites we had chemical data for. The table was displayed as XY data, then exported to a shapefile. Other sites were added as they became available. As was the case with the first group of sites, if the horizontal datum was not known at the time we added a site, the geographic coordinates were treated as being in the World Geodetic System of 1984 (WGS84) datum. Sites whose coordinates were based on the North American Datum of 1983 (NAD83), were first converted to a temporary shapefile, re-projected to the WGS84 datum, then added to the master shapefile of sites.
