Contaminated Site N6 / Lower Austria

Aluminiumschlackendeponie

Subject of Project
Former gravel pit within the Mitterndorfer Senke, to the west of Wiener Neustadt with an exploitation depth of approx. 12 – 17 m. During the period of 1974-1990, waste materials of the wood and textile industry as well as construction waste and powder of aluminium-slag of the Almeta Company were deposited. As a consequence of the waste materials being deposited directly on the porous underground of the gravel pit, the ground water has been affected. The surface of the landfill was partially covered with a mineral seal.

Contaminated Site T5 / Tyrol

Dachpappenfabrik Rum

Subject of Project
A coal tar oil distillation plant was operated at this site in the municipality of Rum from 1908 to 1959. The main products were roofing felt („Dachpappen“), asphalt and other tar products. In 1960, the raw material was replaced by crude oil as part of a change in operations. Until this time, the surface of the factory premises was unpaved. In 1990, soil and groundwater contamination from the roofing felt factory was discovered during the construction of a new filling station / gas station.

Contaminated Site ST28 / Styria

Gaswerk Jakomini

Subject of Project

City gas was produced at the old “Gaswerk Jakomini” / “Gasworks Jakomini“ site between 1845 and 1945. At the end of the Second World War, the plant was almost completely destroyed by bombing and was not rebuilt afterwards. The site is currently home to a tram depot, the main repair facility for trams and administrative buildings.

In the eastern area of the old site, the subsoil is partially contaminated with tar or tar oil, whereby tar has spread locally down to the groundwater table at a depth of approx. 20 meters. A massive influx of pollutants into the groundwater at the site was detected in the course of extensive investigations.

Contaminated Site O40 / Upper Austria

Holzmüllerstrasse

Subject of Project

On this approx. 4 ha wide industrial area in Linz scrap metal dealers and motor vehicle utilization and service centres were situated from the early 1960s to the early 1990s.

Part of this commercial area was used for the temporary storage of scrap metals, domestic waste, bulk rubbish and scrap polluted with oil. In addition, a gas station, a shredder and a scrap and baling press were run.

Due to this, a substantial contamination of the soil and groundwater was detected on the mainly unfortified areal.

Contaminated Site O43 / Upper Austria

Putzerei Lengauer

Subject of Project 
Formerly, the “Putzerei Lengauer“ was a dry-cleaning company, located at the western end of the market square of Schwertberg. During the period 1969–1992, perchlorethylene was used as a detergent at the site. The main issue of this remediation project is the contamination of subsoil and groundwater in the surroundings of a dry-cleaner, which have been polluted by the leakage of detergents.

Extensive contamination plumes have already been detected in the groundwater runoff of the dry-cleaner, where several domestic wells as well as the industrial wells of a machine factory are situated.

Contaminated Site W27 / Vienna

Tankstelle Schlickplatz 

Subject of Project
Between 1926 and 1991, a fuel station was operated on the contaminated site “Tankstelle Schlickplatz” in the 9th municipal district of Vienna. Gasoline fuels and diesel were stored in underground tanks and issued via pumps along a fuel station lane. The available documents indicate the contamination was caused fundamentally by petrol.

The contaminated site has been recorded in the contaminated site register with priority 3 since 2/15/2015. Due to the heavy burden in the unsaturated zone and the fundamentally very good mobilisation capacity of the pollutants, the contaminated site constitutes a considerable risk for the environment.

Contaminated Site N16 / Lower Austria

Tuttendorfer Breite

Subject of Project
From 1927 to 1961, a mineral oil refinery stood on the site on the southern outskirts of Korneuburg, which was severely damaged by bombing during the Second World War. As a result, significant quantities of mineral oil and mineral oil products leaked underground. As a result, the groundwater and subsoil were contaminated. Today, a large part of the site is occupied by warehouses and traffic areas.

Parkplatz Brevillier Urban

Subject of Project
This project involves the redevelopment of an area that is now partly used as a parking lot or as green and residential land. Presumably from the 1940s to the early 1960s, the area was used as a landfill site by a metal processing company. Construction waste, metal waste and excavated material mixed with slag were deposited there. Solvents (CHC) were also introduced into the landfill.

Contaminated Site O58 / Rohrbach-Berg/Upper Austria

Putzerei Gruber (abandoned textile cleaning shop)

Subject of Project

On an abandoned contaminated site referred to as "Putzerei Gruber" a dry cleaning business for clothing was in operation from 1969 to 1982. Since there was no closed-loop solvent cycle in place, as was quite normal in those days, the contact water left over after the process was disposed of via the domestic sewer. The solvent being used was tetrachloroethylene, which was stored in the basement of the residential building (usually without any drip trays).

Initial investigations were conducted back in 1995. The soil air was found to be polluted with tetrachlorethylene at a depth of 1.7 m. Further soil air and groundwater tests were performed at the site in 1998 and later. The last groundwater analyses date back to the year 2003.

Directly downstream of the contaminated site, probe GW3 detected tetrachloroethylene loads of up to 3,600 µg/l in the groundwater.

The contaminated site was entered on the contaminated land register with priority 3 on 5th September 2003.

Contaminated site ST21 / Judenburg/Styria

Putzerei Hlatky (abandoned textile cleaning shop)

Subject of Project

At an abandoned contaminated site referred to as "Putzerei Hlatky" in Judenburg tetrachloroethylene had been used as a detergent ever since the 1950s. In the area of this previous industrial site "Putzerei Hlatky" the non-water-saturated soil zone is substantially polluted with volatile chlorinated hydrocarbons (CHC), especially tetrachloroethylene. Contaminants are being detected in the local groundwater.

Initial investigations were conducted back in 1991. At that time tetrachloroethylene contamination was established in the soil air and trichloroethylene was also identified but attributed less importance. Further analyses followed in the years 1998, 2000 and 2009.

The contaminated site was classified as priority 3 in the contaminated land register on 1st January 2012.

In November 2019 BALSA was commissioned to include the contaminated site in processing in accordance with §18 ALSAG (Contaminated Sites Remediation Act).

Contaminated Site T9 / Tyrol

Rekord Reinigung

Subject of the Project

On the former "Rekord Reinigung" site, which covers an area of around 700 m², a chemical cleaning facility, a laundry facility and a textile dye factory were operated over a period of approx. 30 years. In the area of the former site, there is contamination of the subsoil caused by CHCs and tetrachlorethene that extends into the groundwater fluctuation range.

The source area incorporates an area of 300-400 m² and a volume of approx. 4,000 – 5,000 m³. The emission level currently emanating from the former site was considerable at the time of the last analysis in 2013. The dangerous waste was downgraded to priority 2 on 7/13/2016. At this point in time, the neighbouring plot was also assigned to the contaminated site T9.

Contaminated Site N46 / Lower Austria

Tanklager Mare

Subject of Project:

On this area, mineral oil and mineral oil products have been stored since the 1930s. The site was used as a reloading point for oil for a nearby refinery.
Mineral oil contamination of the subsoil was caused due to the long-lasting operation of the oil depot and thereby involved handling losses, as well as by shellfire damage during the Second World War.
