Geophysical prospecting of bedrock aquifers in Finland

There are about 5.2 million inhabitants in Finland, most of which live in the Southernmost part of the country. 86 per cent of the population is connected to cooperative or public water supplies. In 1995, the average water consumption was about 260 litres per capita per day. The proportion of groundwater of the total water withdraval is about 58 per cent. The official water policy prefers ground water aquifers, because the quality of surface-water varies seasonally and is exposed to environmental risks.
