The Gold King Mine spill occurred in Colorado on August 5, 2015, sending 3 million gallons of mineral-laden waters from the Gold King mine into Cement Creek in Colorado. The discharged waters then flowed downstream into the Animas River, and from there to the San Juan River in New Mexico, before entering Lake Powell in Utah. The Arizona Geological Survey's map of the Gold King Mine spill provides a portal to water and sediment sample locations and data for hundreds of sampling stations along the Animas and San Juan Rivers, Lake Powell, and from nearby wells and irrigation canals in a variety of states.
Users can modify the map's filters to refine the results based on sampling date, location, contaminant type, and whether the sample was a sediment or water sample. Data are available for arsenic, cadmium, lead and mercury, identified by the U.S. Environmental Protection Agency as the primary contaminants of concern due to their potential to cause health risks. The data can be downloaded for further use and analysis.
