The Czech Radioactive Waste Repository Authority (SÚRAO) has started work on monitoring boreholes at sites being assessed for a possible deep geological repository. The first hydrogeological boreholes will provide information about the geological structure and water conditions.
Boreholes will be drilled at all four sites. At areas identified by the Czech Geological Survey, pairs of boreholes will be placed several metres apart. The deeper borehole will reach 100 metres to examine rock formations and groundwater at depth. The second will monitor the quality and quantity of water close to the surface.
SÚRAO Director Lukáš Vondrovic said the work marked an important stage in selecting a final and a backup site. The boreholes will help refine information gathered from surface studies and improve understanding of the geology.
