Contaminated sites and soils

Contaminated soils, burdened with pesticides, heavy metals, hydrocarbons (PAHs), or solvents, present significant challenges for development projects. Effectively managing these soils can be complex and costly, potentially jeopardizing timelines and overall project viability. 
  
Public policies for managing contaminated sites often outline specific, case-by-case guidelines for remediation, weighing the technical feasibility and economic costs of available solutions.  
  
Maintaining residual soil pollution on a site depends on its compatibility with the intended land use—whether for residential, public, or infrastructure development. Site rehabilitation or new construction on such land requires thorough assessment and control of health and environmental impacts to ensure safety and sustainability.

A contaminated site may be, for example:

An industrial site (whether classified as ICPE or not) contaminated due to accidental spills or poor practices.

Open land or brownfields that may have hosted polluting activities in the past or were contaminated through pollution transfer from a nearby contaminated site.

Land on which fill containing pollutants was deposited.

Economic and development opportunities for territories

Hydrocarbon - and PAH - contaminated soils near roads, parking lots, or former industrial sites undergoing redevelopment can be effectively and safely reused on-site with OSMORIA Geoclean decontaminating aquatextiles. 

  

This solution involves confining contaminated soils from uncontaminated areas using a specially designed OSMORIA Geoclean aquatextile. Once encased, the contaminated soil can be securely covered with topsoil. By isolating pollutants within a confined soil mass, OSMORIA Geoclean aquatextiles prevent hydrocarbons from leaching out during water infiltration, keeping contamination contained. The oleophilic filaments of the aquatextile adsorb these hydrocarbons, where they are then biodegraded by natural microbial activity, allowing clean water to pass through without spreading pollutants. 

  

With OSMORIA’s high-performance aquatextiles, hydrocarbon and PAH biodegradation is accelerated, offering a cost-effective way to restore contaminated land. This sustainable approach not only revives local ecosystems but also promotes responsible land reuse and the conservation of natural resources.
