A core sample was collected using the "freezing drive shoe" technology
Detailed Description
A core sample was collected from the uppermost saturated portion of the sandy aquifer using the "freezing drive shoe" technology developed by USGS scientists at the National Crude Oil Spill Fate and Natural Attenuation Research Site. The freezing drive shoe enables nearly complete core recovery from saturated, sandy aquifers.

Natural Breakdown of Petroleum Results in Arsenic Mobilization in Groundwater
Changes in geochemistry from the natural breakdown of petroleum hydrocarbons in groundwater promote mobilization of naturally occurring arsenic from aquifer sediments into groundwater. This geochemical change can result in potentially significant and overlooked arsenic groundwater contamination. Arsenic is a toxin and carcinogen linked to numerous forms of skin, bladder, and lung cancer. Of...
