Willow Spring in Hack Canyon in Arizona north of the Grand Canyon
Willow Spring in Hack Canyon in Arizona north of the Grand Canyon. A sign next to the spring says Water Not Suitable for Drinking. The spring has elevated levels of uranium and selenium. The elevated uranium level is most likely not associated with breccia-pipe uranium mining in the area.

Hot plate set-up
After mixing about 20 grams of a sediment sample with distilled water, we add strong hydrogen peroxide to break down or "digest" organic matter that may be in the sample. Organic matter makes clay particles stick together and we need them separate in order to calculate accurate particle size fractions of the sample.

Highflow measurement downstream of a dam
High flow measurements are important is refining and confirming the validity of the high end of discharge ratings. Here, a technician moves the manned boat back and forth across the river channel with an ADCP tethered to the side of the boat.

Honey bee pollination of coffee plants
Researcher swabs the body of a honeybee with fuschin gel to later use to identify the pollen particles on the bee's body and determine what plants the bee visited.

Brazilian waterweed
Tips of Brazilian waterweed (Egeria densa) break the surface at low tide in Lindsey Slough in the northern Sacramento-San Joaquin River Delta. More commonly, this invasive plant is completely submerged.
