Scientist Uses a Syringe to Withdraw Water from a Core

Detailed Description

To help understand the geochemical conditions that control arsenic mobilization in the subsurface a USGS scientist uses a syringe to withdraw water from a core for analysis. The core sample was collected using the "freezing drive shoe" technology developed by USGS scientists. The freezing drive shoe enables nearly complete core recovery from saturated, sandy aquifers. The core is shrouded in aluminum foil to prevent oxidation.
