In case of imminent endangerment of the environment, BALSA GmbH undertakes the projecting and realisation of measures for the protection / remediation of affected properties.

Contaminated site ST7 “Gärtnerei Thianich”


Project type:

Up to the beginning of the 1980s, the “Gärtnerei Thianich” was located on this plot of land at the east end of the municipality of Zettling. The company´s equipment included a heating house and a mineral oil stock. On the areal of the former heating system, contaminations of the underground were detected. In the 1970s, oil ingresses into the nearby well happened. In 1992, the contaminated subsoil was partially trenched. Part of the contaminated soil was stored on the site wrapped in polyethene sheets.
