USGS Groundwater Information: Branch of Geophysics
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. |
