U.S. River Conditions, July to September 2024 thumbnail image. The river conditions shown range from the driest condition seen at a gage (red open circles) to the wettest (blue closed circles). A purple outer ring around a gage indicates it is flooding.

Orange streams are increasingly common in the Brooks Range of northern Alaska. The orange stream color reflects oxidized iron, but also often indicates elevated heavy metal concentrations. Our ongoing study aims to document these occurrences and the timing of their onset.

Schematic diagram of water flow through a conventional copper-ore flotation plant and unlined tailings storage facility illustrating water losses (in italics), reclamation of process water, and addition of makeup water.

The Selenium Bioaccumulation and Contaminant Research Laboratory's Inductively Coupled Plasma Mass Spectrometry (ICP-MS) set up for low mass, low concentration selenium analyses of most matrixes using hydride generation-isotope dilution-inductively coupled plasma-mass spectrometry (HG-ID-ICP-MS).

Profile view of a Bell Jet Helicopter with a thermal infrared and true-color sensor co-mounted to the underside of the nose. These sensors are used in airborne thermal infrared surveys for remotely sensing land/water surface temperature.
