The paper presents an ensemble of software modules, integrated
in a single platform, suitable for oil products based pollution
risk management through processes of identification, analysis,
monitoring/systematic reporting of soil and groundwater pollution
risk factors, through execution of plans to reduce pollution by
means of involvement of some innovative in-situ technologies based
on electrokinetic bioremediation.
Several aspects dealing with the use of GIS technologies to monitor
both the pollution and restoration issues as well as some preliminary
information on a data model generation able to collect and manage
an extended range of information that may be spatially integrated
are discussed.
Also, the paper presents some preliminary laboratory experimental
tests regarding the influence of some operating parameters (applied
potential, electrodes type, electrodes distribution) on the degradation
rate of some organic compounds as contaminant agents (e.g. phenol)
with permanent recording of soil water content, pH.
Software implementation will use modalities that are similar to
those met in the specific reference European methodology, integrating
the application of geographical information systems (GIS) through
specialized modules (with ESRI –ArcGIS- ArcView) and the involvement
of imagistic controlling that will provide significant information
on the health state of a specific area towards an interested authority
and will contribute to take strategical and tactical decisions
in order to prevent and to act by means of planning, budgeting
and monitoring of the economical/social performance. The obtained
values of the indicators of soil and groundwater oil pollution
will be represented at territorial scale, so that the pollution
risk assesment digital maps will be obtained; on their basis critical
areas will be evidenced in the case of pollution and the information
maintenance/updating will be kept in a spatial database, a history
of these interest values being able to be built. Due to the complexity
of the analysis, the deep approach of each distinct component
is necessary, so that it is to be able to optimally contribute
within the entire ensemble towards application of a hazard-vulnerability-risk
assessment methodology at the impact level of soil and groundwater
pollution for the specific pilot area selected for the analysis.

Among in-situ restoration technologies
based on physical-chemical phenomena, the electrokinetic remediation
attracted an increased interest of scientists and final users.
It can be applied alone or associated with other treatments (e.g.
bioremediation) and enhances directly or indirectly the degradation
rate of the pollutant agent.
Generally, the electroremediation procedure is based on applying
of a potential difference between several electrodes distributed
in various configurations and positioned at different distances
onto the soil subjected to ecological restoration in depth, thus
creating an electrical field. Under the action of the imposed
electrical field the contaminant agent is mobilized due to the
electrokinetic forces from one electrode area towards the other
one where it is collected and then removed. Contaminants migration
under the action of an imposed electrical field is done through
electroosmosis, electromigration and/or electrophoresis processes.
With this in view, the paper presents some preliminary laboratory
experimental tests regarding the influence of some operating parameters
(applied potential, electrodes type, electrodes distribution)
on the degradation rate of some organic compounds as contaminant
agents (e.g. phenol) with permanent recording of soil water content,
pH. Additionally, several aspects dealing with the use of GIS
technologies to monitor both the pollution and restoration issues
as well as some preliminary information on a data model generation
able to collect and manage an extended range of information that
may be spatially integrated are also discussed.
