Lower Saxony's Steady Stride to Clean Up Contaminated Sites
Progress in removing contaminated sites in Lower Saxony might not be as rapid as we'd all hope, but it's certainly moving in the right direction. By the end of July 2023, the number of remediated and harmless sites had creeped up slightly to 3,034, from a mere 2,853 in 2018. One of the towns spearheading this effort is Wittmund in East Frisia, where the effort to rid contaminated sites of harmful substances is palpable.
Lower Saxony's Contaminated Land Minefield
The state bears the burden of over 100,000 suspected contaminated sites, a staggering number that includes relics from the industry and military past, as well as obsolete landfills. Of these, around 4,000 sites have been classified as contaminated and in desperate need of a makeover, but have yet to see a remediation plan.
The Sordid Tale of Toxins in Wittmund
Wittmund, in East Frisia, is home to one of Lower Saxony's contaminated sites, plagued by perpetual chemicals like PFAS. These pesky substances have found their way to the NATO airfield, requiring an on-site soil washing facility that began operation in January 2023. By 2026, an estimated 800,000 tons of PFAS-laden soil will be remediated, to be reused for construction work at the airfield.
The Remediation Team's Labor of Love
The labor of love to rid Lower Saxony of contaminated sites falls in the hands of the lower soil protection authorities, responsible for conducting inspections and remediation work on the suspected sites. In Wittmund, for example, the authorities have successfully removed hazards from approximately 4,430 sites, a number that has inched up from 3,766 in 2021.
Regional Differences in Contaminated Sites
Contaminated sites can be found in every corner of Lower Saxony. One significant difference lies in the type and origin of these sites. For instance, southern Lower Saxony holds almost no suspected sites from sludge pits associated with oil and gas extraction, but it boasts a rich legacy of military waste. Towns like Lüneburg Heath, Cuxhaven, and Wilhelmshaven are particularly rife with contaminated military sites.

For further information on Lower Saxony's comprehensive efforts in removing contaminated sites, particularly focusing on the application of soil washing facilities in the handling of hazardous substances like PFAS, we recommend consulting regional or local government reports, environmental agency publications, or specific studies conducted in Lower Saxony.
Notable Environmental Contamination Sites in Germany:
- The Elbe River, which flows through various regions in Germany, has shown high concentrations of organic micropollutants, including pesticides and pharmaceuticals, impacting the river's water quality and cytotoxicity.
- The Bilina River, located near an area with a history of heavy industry, exhibits high levels of petrochemical pollution, as well as contaminants like sucralose. This suggests that both municipal wastewater and industrial activity have negatively impacted the river's ecosystem.
Post-Mining Landscape Restoration in Saxony-Anhalt:
- The process of restoring post-mining landscapes in Saxony-Anhalt involves addressing soil contamination through measures such as adding organic materials, lime, or fertilizers, as well as planting vegetation to improve soil quality and stabilize soil structures.
Examples of Post-Mining Landscape Restoration in Saxony-Anhalt:
- The creation of the Geiseltalsee lake in Saxony-Anhalt required flooding a decommissioned lignite mine and planting vegetation to fortify the soil and increase its natural health.
- The challenges of restoring soil fertility and addressing soil compaction and acidification in Saxony-Anhalt are being addressed through careful planning and the implementation of sustainable soil management practices.
