Engineering services to explore the deeper underground, engineering services to provide expert advice on groundwater remediation using arsenic mobilization, risk assessment and optimization of groundwater remediation.

The former factory site of the Neuschloß chemical factory is located east of Lampertheim in the Neuschloß district. From 1827 to about 1927, soda, sulfuric acid and artificial fertilizers were produced here. Soil investigations and further explorations showed the widespread presence of soil contamination and groundwater contamination with heavy metals (especially arsenic) and organic pollutants. Starting from the old site of the former chemical factory, a large-scale pollutant flag characterized by arsenic had formed over time, which today stretches across the residential area from Neuschloß to the northwest in the direction of the drinking water production in the Bürstädter Wald.
