Conceptual framework
- Automobile components historic company of 9 Ha.
- Industrial plant near to the coast and urban centre.
- Deep confined aquifer. Water-table level around 25 m of depth.
- Old contamination focus, delimit.
- It is presented initially a hydraulic barrier for stopping the migration of pollution plum and have the leisure to research the unsaturated zone.
Parameters to address
- Affectation for hydrocarbons. Floating free phase pollution plum over 2.000 m2.
- Affectation for organohalogenated compounds (trichlorethylene, tetrachlorethylene and vinyl chloride).
- Affectation for heavy metals (antimony, chromium VI…).
Treatment
- Hydraulic barrier with automatic pneumatic pumps downstream.
- Separation and decantation of DNALP.
- Filtration system by activated carbon and iron zerovalent particles (Fe0).
