CONTENT
  • European statistics on soil pollution
  • Activities and chemicals that cause pollution
  • Finnish system for determination of soil pollution
  • Three main approaches to remediation
european statistics on soil pollution
European statistics on soil pollution
  • 750.000 polluted sites in Europe

(Haavisto 2008)

  • soil contamination is number one problem for more than 60 % of Europeans

(Ademe, Polluted sites and soils)

finnish assessment for determination of soil pollution
Finnish assessment for determination of soil pollution

Lower advisory value

Treshold value

Unpolluted, but higher

pollutant concentrations

exist

Unpolluted

Polluted

  • exceeding of treashold value starts general risk assessment
  • exceeding of lower advisory value starts closer risk assessment =>
  • a) risk can be accepted b) site has to be remediated

three main approaches to remediation
Three main approaches to remediation
  • OFF SITE
    • soil or groundwater is transported somewhere to be treated
  • ON SITE
    • polluted masses are excavated and treated on site in transportable treatment plant
  • IN SITU
    • treatment takes place without excavation
