| Project objectives:
The CLEANSOIL project will develop and promote the on-site in-situ treatment of hazardous substances at local point source by means of adsorption mechanisms.
Based on its simplicity it is specially targeted for large areas of polluted land, and when removal is not practicable i.e. under existing infrastructures.
The CLEANSOIL remediation method will reduce the potential risk of pollution spread through soil and water sources and will help to revitalize valuable
space in outer and inner city areas. Besides the CLEANSOIL method will prevent health damage and improve the quality of life for humans, animals and plants.
The proposed project will investigate and clearly define the potential applications of the CLEANSOIL system. By making the necessary adaptations, selective
systems for each kind of contaminant will be established, which will allow to offer solutions for large contaminated areas at moderate costs. Still further
applied research is required in order to adapt the method to different soil conditions and contamination problems. With these aim, tests will be conducted
for selection of the most suitable sorbents and reactive agents for the removal of a wide range of pollutant compounds in conjunction with studies of soil geological
properties and the hydraulic characteristics.
| Achieved Objectives:
During the three years duration project, the research work comprising the 8 work packages have been developed according to the figure below. During the first
work package (WP1), the problem in its environmental, social and economic dimensions for the involved countries will be defined, and a set of parameters and
for the evaluation of the project progress and results established. Further, a detailed specification of the situation in the targeted areas where the CLEANSOIL
system will be implemented will be carried out (WP2). This research will be the base for identifying appropriate sorbents for each specific pollutant source
in WP3, which will be tested at laboratory scale soil column experiments in order to define the most relevant design parameters for the system. In WP4, based
on the already established local conditions, the system will be designed and dimensioned and a complete sampling test programme developed. According to the
design, in WP5 the CLEANSOIL concept will be constructed at the selected sites, and the system will be operated. Samples from the soil, the groundwater and the
soil solution water, as well as the sorbents will be periodically analysed. In WP6 the CLEANSOIL performance will be evaluated based on the data compiled during
the field tests. The values obtained after the treatment will be compared to the initial concentrations and to the fixed objectives. After the end of the testing
period, the system will be removed definitely. Based on that, a study on the economic, technical and environmental feasibility of the whole system will be developed.
In parallel to the above mentioned activities dissemination tasks (WP7) will be held in order to raise public awareness about the problems and the solutions
offered by CLEANSOIL (communication with relevant stakeholders, presentations, publications, conferences).
