Getlini waste disposal site has been the major landfill for Riga City since more than 20 years. Due to the conditions at the site and indications on contamination of the groundwater aquifers there were plans to close the site and establish a new landfill. However, those plans were later revised as it was found that the most appropriate alternative would be to remediate the old parts of the disposal site and continue the landfilling operations utilising modem technologies. Based on this information it was decided to carry out a feasibility study including investigations of the environmental impact from the existing disposal site and propose measures for remediation of existing contamination as well as recommendations on how to continue the operations in an environmentally acceptable way. The feasibility study was carried out by SWECO, in association with GeoKonsultants in accordance with an agreement with Riga City Council and financed by Sida and Riga City.
