  1. Overview of groundwater and soil contamination in Lithuania Kestutis Kadunas, Geological Survey of Lithuania Tel. 370 5 2136 272, E-mail.Kestutis.Kadunas@lgt.lt

  2. Prepare law on responsibility for damages caused by former activity Law on topsoil protection Inventory of polluted sites including sanitation programs Reclamation of old landfills Restoration of polluted sites Organization of sanitation of former pesticide storages Action plan in environment management Source:Environment protection strategy of Lithuania, 1996

  3. Groundwater use and protection Strategy, 2002 - 2010 • To prepare and keep the Register of Pollution Sources of the Geological Environment • To surveypollution sources, to carry out their monitoring, to establish priorities of reclamation, to prepare programmes, to initiate the sanitation of priority territories • To produce methodical recommendations on investigation and monitoring of pollution sources • To set pollution thresholds in the soil and groundwater

  4. Overview of contaminated lands(point sources of pollution) • Sanitary landfills and waste sites • Former and present military sites • Civil oil facilities • Pesticide storages

  5. Inventory of sanitary landfills & waste sites • Inventory of sanitary landfills and waste sites carried out in 1993; • Totally 636 sites find out; • In 264 sites storage of chemical wastes were ascertained; • Detail investigation carried out in 36 sites; • Calculation of remediation for 8 sites - 1,5 bil. USD Source: Kruger Consult & Geological Survey of Lithuania

  6. Inventory of sanitary landfills & waste sites • Group “A” - dangerous sites, detailed investigations and sanitation needed; • Group “B” - investigations for decision needed; • Group “C” & “D” - no chemical waste, limited investigation Source: Kruger Consult & Geological Survey of Lithuania

  7. Industrial landfill, Ketvergiai • Wood (bark) waste • Sludge from waste • water treatment plant • 500000 + 100 000 m3 • Contamination of • GWponds SW • Phenols, NH4, • organic compounds • Risk to contaminate • private dug wells • Contaminated SW • flows to Baltic see Source: Geological Survey of Lithuania

  8. Obeliai waste disposal • Waste of alcohol production • Oil waste • Domestic waste • Contamination by mineral • oil, heavy metals • Polluted area - > 100 000 m2 • Total volume to be purified • 9 000 000 m3 • Remediation cost ± 1,5bil USD Landfill Contaminated GW Source: Geological Survey of Lithuania & Ecorem

  9. Former and present military facilities • The inventory carried out in 1994 • In 275 sites were located 421 units • 160 sites are polluted by hydrocarbons • In 35 cases surface water pollution • In 10 investigated sites remediation action needed Source: Kruger Consult

  10. Registered soil & groundwater contamination in military sites • Oil contamination - 556 • Chemicals - 56 • Rocket fuel - 20 • Waste sites - 478 Source: Kruger Consult

  13. Civil oil facilities (petrol stations,oil storages) Source: GROTA Ltd

  14. Number of civil oil facilities • Small storages 5000 • Petrol stations 423 • Oil storages 30 • Power plants 130 Source: GROTA Ltd

  15. Area of civil oil facilities Source: GROTA Ltd

  16. Number of investigated civil oil facilities . Source: GROTA Ltd

  17. Areas of contaminated soils & groundwater in civil oil facilities(167 sites) Source: GROTA Ltd

  18. Remediation plan for Bugeniai railway station • Contaminated area with oil • concentration > 5000 mg/kg • exceeds 40 000 m2 • Entire area inside ring road needed • for remediation 427 067 m2 • Cost of remediation according • Lithuanian norms 7.507.000USD • Full cost - 33.917.498 USD Source: Geological Survey of Lithuania & Ecorem

  19. Pesticide storages • 954 pesticide storages inventored in 1996 - 97 • Not detail investigation carried out (18 investigated) • Not action plan developed Source: Geological Survey &Ministry of Environment

  20. Grave of pesticidesŽygmantiškės, Šalčininkai • In groundwater: simazin, prometrin, propazin,atrazin •  - and  - HCH were discovered in 1995 m. • Sum of pesticides 35 - 200µg/l Source: Geological Survey of Lithuania & Minstry of Environment

  21. Source: Geological Survey of Lithuania & Ecorem

  22. What we lack to be faster ?? • Law on responsibility for damages caused by former activity • Developed clean - up priorities/criteria • To develop methodology for prioritisation of inventored sites for action plan design

  23. Environment standards & regulations • Maximum permitted concentration of oil products in soils and groundwater LAND 9-2002 (clean-up criteria) • Order on Inventory and Information Collection of Discharges to Groundwater of the Main Pollutants (priority substances)(describes order for declaration of potentially contaminated sites, sets limits for groundwater contamination

  24. Results of inventory of contaminated sites (Register at the Geological Survey of Lithuania)
