from a stinking wastewater disposal field toward a Recreation Area the story of an unconventional soil remediation in berlin germany
Journal of Soils and Sediments, 2018Co-Authors: Gerd Wessolek, Bjorn Kluge, Steffen Trinks, Michael Facklam, Olaf ZeuschnerAbstract:Purpose Wastewater irrigation is still a common practice in many cities worldwide. After ending the wastewater irrigation, the question arises as to how the highly polluted Areas can be reused. Mostly, the remediation costs for liming or adding synthetic soil conditioners are too high for decision makers, often leading to unattractive wastelands in neighboring suburbs. This story shows how part of a former wastewater disposal field in Berlin (Germany) was remediated by adding and mixing loam-rich glacial until excavated from subway construction work. The remediation led to long-term improvements of soil and landscape, which nowadays is an attractive forested Recreation Area. Part of this landscape is used as an ecological lab for research, art, and education.

Materials and methods The article summarizes the results of soil analysis of the contamination status and remediation technique over the last 2 decades. We collected and reevaluated historical data, research results, technical reports, and graphic materials concerning the wastewater disposal field in Berlin, Germany. Results and discussion The remediation concept without adding any synthetic substances was a successful soft technology leading to (i) a reduction of the long-term groundwater risk, (ii) an immobilization of the trace element concentration in the soil solution, and (iii) a reduction of the metal uptake by plants. Remediation led to much better conditions for plant growth, soil fauna, and microbiological activity, which improved the environment in a sustainable way. The implementation of a new landscape concept combining ecology, culture, and art totally changed the character of the landscape from former stinking wastewater fields to present-day attractive sites that can be used for many purposes. Conclusions The remediation of the former wastewater disposal fields, using natural glacial till materials rich in clay and silt, became a “story of success.” However, a remediation project of this type and scope only becomes reality if all responsible actors in society participate continuously. We conclude that stakeholders should not focus only on remediation costs but also on the benefits for society: reclaiming waste sites significantly improves our well-being.

Genetic diversity and population genetic structure of the Wood Turtle (Glyptemys insculpta) at Delaware Water Gap National Recreation Area, USA
Conservation Genetics, 2009Co-Authors: Christina M. Castellano, John L. Behler, George AmatoAbstract:Glyptemys insculpta is considered to be one of the most endangered freshwater turtles in North America. Here microsatellite markers were employed to investigate the genetic variation and population structure of G. insculpta at Delaware Water Gap National Recreation Area (USA). Seven microsatellites revealed high allelic variation with 13–30 alleles per locus. Observed and expected heterozygosities per locus ranged from 0.875–0.925 to 0.888–0.952, respectively. Pairwise estimates of population structure ( θ ) ranged from 0.000–0.013 to θ estimated over all loci and aggregations was not significantly different from zero. Gene flow ( Nm ) was high and ranged from 19 migrants per generation to infinity in pairwise comparisons. No significant relationship between geographic distance and genetic distance was detected. These data indicate that G. insculpta at DEWA represent a single, genetically diverse management unit for conservation.
