Water tracing dye was injected into a stream in Leadville, Colorado, to identify locations of metal loading and to guide geophysical measurements.

Butterflies and moths are submitted to the KS WSC for the Lepidoptera Research Collection Citizen Science Project. Julie Dietze holds a sphinx moth received from Texas. 

A long-term fiber-optic distributed temperature sensing monitoring array installed along Cement Creek near Silverton CO to track acid mine influenced groundwater discharge to the creek over time.

Specimens from a USGS Lepidoptera Research Collection stored at the Kansas WSC Organic Geochemistry Reseearch Laboratory. Specimens are received as part of a Citizen Science effort to establish a collection to further insect research. 

Smallmouth Bass are good indicators of methylmercury exposure to humans and wildlife because they are a common, popular sport fish and eat a variety of food during their lifetime. Juvenile Smallmouth Bass – smaller than 150mm in length - eat zooplankton, or microscopic animals.

This USGS map shows the number of PFAS detected in tap water samples from select sites across the nation. The findings are based on a USGS study of samples taken between 2016 and 2021 from private and public supplies at 716 locations. The map does not represent the only locations in the U.S. with PFAS.
