SOIL

Soil protection

he functions of the soil must be sustainably protected or restored in accordance with the German Federal Soil Protection Act. To accomplish this, harmful changes in the soil must be averted, the soil must be cleaned up and precautions against detrimental soil impacts must be taken. In case of soil impacts, damage to its natural functions and its function as an archive for natural and cultural history is to be avoided as far as possible.

Which services do we offer?

• We conduct soil pressure testing for tank storage facilities.
• We inspect the soil density of biogas plants.
• When examining playgrounds, we provide you with a detailed sampling and analysis of playground sand.

Examples of soil damage:

Tank storage facilities: Systems for handling substances hazardous to water must be constructed so that no water is contaminated. In case of flat-bottom tanks, leaks can be quickly and reliably detected if they are double-walled and equipped with leaks monitoring systems, or the foundation of the tank is designed so that leaks in the base area can be immediately detected when storage liquid leaks into the catchment area.

Biogas plants: When substrate leaks, the leak tightness must, in individual cases, be verified with an appraisal in conjunction with a current sampling near the storage container.

Playgrounds: Playground soil (e.g. playground sand) can be contaminated through the air pathway by traffic and the industry. There is a risk of a concentration or enrichment of pollutant, since particle-bound pollutants cannot be removed by sand cleaning machines.


Which standards and statutory regulations form the basis of our work?

The technical rules for substances hazardous to water (TRwS) 133, edition 1997 flat-bottom tanks for storing liquid hazardous to water serve as the foundation of the legal framework for tank storage facilities.

For biogas plants, there are concrete requirements devised for water protection when installing and operating biogas plants in Lower Saxony according to the guidelines for plant-related water protection of the Lower Saxony Water Management, Coastal Defence and Nature Conservation Agency (NLWKN).

In addition, the regulations of the German Federal Soil Protection Act from March 17, 1998 (BGBl. I S. 502), last amended by article 3 of the law from December 9, 2004 (BGBl. I S. 3214), also generally apply.
