Glossary
filter function
Due to the filter function of the soil, even very small dirt or pollutant particles can be bound in seeping water. This prevents contamination of the groundwater.
fossils
Fossils are the remains of living things or traces of living things that are more than 10,000 years old. The formation of fossils is called “fossilisation”. Fossils are formed when dead living beings are sealed off from oxygen in sediment and no more change processes take place in the earth’s crust.
