Mineral elements provide the color in fireworks. Barium produces bright greens; strontium yields deep reds; copper produces blues; and sodium yields yellow. Other colors can be made by mixing elements: strontium and sodium produce brilliant orange; titanium, zirconium, and magnesium alloys make silvery white; copper and strontium make lavender.

U.S. Geological Survey activities related to American Indians and Alaska Natives: Fiscal years 2009 and 2010
Leachate chemistry data for solid mine waste composite samples from Silverton and Leadville, Colorado
EPA method 1312 (synthetic precipitation leaching procedure); leachate chemistry data for solid mine waste composite samples from Silverton and Leadville, Colorado
Compositions and metal loadings from several seeps at the Summitville Mine: Preliminary results of sampling in August, 1995, and comparison to August, 1994 results
Geochemical processes controlling acid-drainage generation and cyanide degradation at Summitville
The effect of acidic, metal-enriched drainage from the Wightman Fork and Alamosa River on the composition of selected wetlands in San Luis Valley, Colorado
Mississippi Alluvial Plain (MAP) Regional Water Availability Study
The Mississippi Alluvial Plain (MAP) has become one of the most important agricultural regions in the US, and it relies heavily on a groundwater system that is poorly understood and shows signs of substantial change.
