Cross Well Radar: Detection and Monitoring Technique
perseverance in the environment. Additionally, these
compounds may be mixed. The combination of PCE and
TCE is the most frequently occurring mixture due to
the transformation of PCE to TCE through reductive
dechlorination
Soil and ground water contamination by chlorinated
hydrocarbons as DNPALs represent a persistent
environmental problem because in relatively small
concentrations can change the quality of the
groundwater (GW) resources. These chemical can move
using the GW flow causing, sometimes, formation of
aqueous-phase plumes contamination, and occupying much
larger aquifer volumes, posing much more risk to
receptors and the environment.
Knowledge of the dynamics of water and solute or
pollutant transfer in soil is relevant in remediation
technologies. Therefore there is a strong need for the
development and integration of novel techniques, which
allow detection and monitoring of contamination in
surface and subsurface processes at spatial scales
relevant. Cross Well Radar is being used to detect
buried objects in a frequency range between 500 to
1000MHz using loop antennas. This technology can be
used to detect TCE movement, as may detect changes in
the water content inside a soil. An experimental
protocol has been developed to use CWR to detect and
visualize DNAPLs distribution in the soil.
Maria F. Serrano-Guzman, University of Puerto Rico Maria Fernanda Serrano is a doctoral student in University of Puerto Rico at Mayaguez. She is associate professor in Civil Engineering Department in University Pontificia Bolivarian (Colombia). She started her doctoral studies in 2002. Her work has been focused in transport of contaminants in the vadose zone.
Ingrid Padilla, University of Puerto Rico Dr. Ingrid Padilla is currently an associate professor in Environmental and Water Resources Engineering in the Department of Civil Engineering and Surveying at the University of Puerto Rico (UPR), Mayagüez. She has been at the UPR since 2001. Prior to that, she directed the Groundwater Office at Greg Morris and Associates, San Juan Puerto Rico and worked as a groundwater hydrologist at the U.S. Geological Survey. Dr. Padilla has received numerous awards through her career, including: Distinguished Professor in Civil Engineering; Ford Foundation Fellowship, and several outstanding minority awards. She has published in distinguished journals, such as Water Resources Research.
