For the town of Březnice, we conducted a contamination survey and risk assessment at the former KOVO site, which produced furniture and construction fittings. The objective was to delineate and verify the extent of groundwater contamination by chlorinated hydrocarbons and other substances threatening the local brewery’s water source. Based on the risk analysis, remediation of both soil and groundwater was recommended.

In 2015, the project “Probable Environmental Burdens – Surveys at Selected Sites in the Slovak Republic” was launched under the Operational Programme Environment, overseen by the Slovak Ministry of the Environment. Each site underwent contamination surveys and risk assessments. As a subcontractor to the main project contractors DEKONTA Slovensko and ENVIRONEDGE, we participated in the risk assessment studies for the following sites: industrial and toxic waste landfill in Vrakuňa, pesticide storage site in Nová Dedina, railway depot in Bánovce nad Bebravou, Kovohuty Krompachy, Skrutkáreň Stará Ľubovňa, and the former chemical warehouse in Strihovce.

In cooperation with the international consulting firm Ramboll, we took part in a purpose-specific risk assessment study for part of a pharmaceutical site where demolition of a former chemical production building was planned. Soil and groundwater contamination—primarily by volatile organic compounds (VOCs)—was confirmed. The study evaluated health risks during and after demolition, as well as the potential for contamination to leach into groundwater via infiltration. Follow-up measures to minimise these risks were recommended based on the assessment results.

In collaboration with HECON and ERM, we participated in a risk assessment study for an industrial site in the eastern part of Kolín, a location with over a century of industrial activity. The site presents complex hydrogeological and geological conditions, such as its position on a hydrogeological divide and the presence of remnants of Cretaceous sediments. The study also assessed the potential inflow of contamination from neighbouring industrial facilities.

Together with DEKONTA, we contributed to a risk assessment study for the extensive Istrochem chemical plant in Bratislava. The area was contaminated with a wide range of chemicals resulting from the production of explosives, pesticides, herbicides, and rubber processing agents. Two scenarios for future land use were considered: continuation of industrial operations or full redevelopment into a residential zone. Based on the risk analysis, remediation of soil and groundwater was recommended for both options.

For Panattoni, we developed a risk assessment based on a site investigation of historical subsurface impact at the former POLDI Engineering Works in Kladno. In collaboration with the Czech Environmental Inspectorate (ČIŽP), the state enterprise Povodí Vltavy, and other stakeholders, we proposed remediation target values and outlined a framework for remediation and redevelopment activities, aligned with the site's planned conversion into a modern industrial and logistics park. The investigation and expert support were carried out in coordination with Vodní zdroje a.s., which oversees the overall remediation strategy for the industrial area.
