USGS researchers at UConn research site.
Current was injected into trees using nails as electrodes.
Electrical resistivity soundings were conducted on a sample of trees.
Apparent resistivity was measured and recorded using a dc resistivity meter.
Apparent resistivity values at different distances into the tree and in trees at different locations were compared.
Trees were selected due to their position relative to known contamination plumes.
