A dangerous leak has been liquidated at Olaine hazardous materials landfill. Potential risks of the leak repeating or tapping into groundwater have been prevented as well. With that, residents can feel safe about the state of the environment, reports Latvian State Environmental Service.
As part of clean-up at Olaine liquid hazardous materials landfill, solid waste materials and liquid waste have been cleared from four waste pools.

The total area that was cleared of waste at Olaine hazardous materials landfill is 29,450 m2.
In order to provide monitoring of groundwater quality after the clean-up, specialists have set up special wells and added post clean-up monitoring system. In the coming years, specialist will be taking samples of groundwater and running them through the system to gather information on results of the clean-up.
VentEko carried up the clean-up of dangerous materials at Olaine hazardous materials landfill. Monitoring was carried out by Geo Consultants. The project was performed as part of European Regional Development Fund’s initiative. The end costs of the project reached EUR 6,773,270 (with VAT).
«Environmental clean-up work has been completed in one of Latvia’s most polluted territories. The whole process was carried out in a short period of times and with high quality and with use of modern environmental engineering solutions. This project has helped up reduce the number of polluted areas in our country, and now we can draw inspiration for future endeavours in the clean-up project of the most polluted project – Incukalns. Olaine’s project is also proof that there are smart, capable and professional companies in Latvia that cleverly use the finances provided by the EU and are reliable partners in solving complicated environmental problems,» – Inga Kolegova, SES Director General, expresses her satisfaction.
One of the objectives of SES is organizing the clean-up of four historically polluted areas in the country. In 2012, the clean-up of Jelgava’s Kosmoss landfill was successfully finished. October 2015 marks the completion of the clean-up in Olaine. With help from the Swiss government, work is currently being done in Sarkandaugava – over at Riga Freeport, where it is planned to clean up the Incukalns tar ponds by 2019.
