The project has been carried out in the frames of R&D Study on detection of hydrocarbon
pollution of soil and groundwater with the use of geophysical methods
supported by Polish Ministry of Science and Higher Education and Programme
of Structural Funds “Competitiveness”.
The overall goal of the project was to utilize related knowledge and
expertise of research partner – AGH University of Science and
Technology in order to help the contractor, service company – PBG
Ltd. Geophysical Exploration Co., to develop methodology on effective use
of geophysical methods for
detection and monitoring of hydrocarbon pollution on areas of old oil
fields. These areas are intended in not to distant future (after oil
production is finished) to be converted for the use of local communities.
This means site characterization (where pollution might occur) and, in case
remediation programmes are to be applied, monitoring of the process.
The study enclosed site characterization (where pollution might
occur), geophysical field measurements and drilling piezometers in two
mining areas (oil fields) located in SE part of Poland (Carpathians), where
oil production started in XIXth century and still proceeds. The more
technical goal of the project
was to determine relationships between results of geophysical field
measurements (ERT, GPR) and soil and groundwater properties, especially
those related to hydrocarbon pollution. The entire project includes:
-
data inventory
and elaborating of criteria to design field measurements,
-
numerical
modeling of pollution range and fate (AGH) within selected, characteristic
soil types,
-
surface and
cross-hole geophysical measurements (and drilling necessary piezometers),
-
optimization of
data processing procedures,
-
computer
simulation of electromagnetic wave field (AGH),
-
evaluating
relationships between geophysical parameters and soil and groundwater
properties in case of sites in question and in general.
Results of numerical modeling of pollution range and migration have
been used in order to design
geophysical surveys and for interpretation of survey results.
Computer simulations of electromagnetic wave field have been performed
basing on soil characterization, results of field geophysical survey
and results of numerical modeling of pollution
range and migration. Simulation results have been employed in order to
optimize processing and sozological interpretation of GPR survey data.
It follows from the investigations results of ERT and GPR field
geophysical survey can be used for
detection of pollution zones within groundwater and soil system
provided they will be correlated with results of numerical (computer)
modeling of pollution range and migration within selected, characteristic
soil types and results of computer simulation of distribution of
electromagnetic wave field within polluted grounds.
