Potentially polluted areas undergo stock survey

2011-12-29

Thirty-nine municipalities of Lithuania have undergone a stock survey of potentially polluted areas. The work was carried out as part of the EU-supported project on the assessment of impact of such areas. The project was implemented by the Ministry of Environment, the Environmental Project Management Agency and the Geological Survey of Lithuania.

According to Kęstutis Kadūnas, head of the Hydrogeology Division at the Geological Survey of Lithuania, the country has over 11,000 potentially polluted areas. To implement the project, the stock survey covered a territory of 39,300 square kilometres. A hundred sites were subjected to eco-geological investigation, and fifty sites underwent detailed studies and were assessed in terms of their impact on the environment and humans. The investigation involved sites of oil depots, reservoirs, manufacturing plants, technology grounds, boiler houses and other territories. The detailed studies calculated the quantities and areas of polluted soil and groundwater for each site.

The results have shown that soil is polluted with oil products in thirty-five out of fifty sites investigated. Such soil covers an area of more than 66,000 square metres. Eleven sites measuring an area of 2,262 square metres contain pesticides in the soil. At four sites some 330 cubic metres of soil are polluted with heavy metals.

Groundwater shows pollution with oil products at thirty-five sites investigated that exceed an area of 55,000 square metres. At four sites groundwater is polluted with pesticides, at seven sites with heavy metals, at thirty sites with different nitrogen compounds, at six sites with chlorides and at four sites with sulphates.

The cleanup costs for the polluted areas under investigation have also been calculated. The calculations show that the cleaning of one small part of the polluted areas identified would require several hundred million litas.
