Contaminated sites in Austria

from Wikipedia, the free encyclopedia

This article gives an overview of the known contaminated sites in Austria .

introduction

In Austria, a distinction is made between three categories of old deposits (landfills) and old sites (operating areas):

  • Contaminated sites in the legal sense of the law are only those contaminated areas, 1989 (entry into force of before July 1 Remediation Act originated), and in contaminated sites of the Federal Environment Agency as contaminated sites are registered because of these old deposits and old a significant health hazard Run out of people or the environment. They must be secured or rehabilitated, or under observation after rehabilitation.
  • Suspected areas are areas reported to the federal government by the federal states that have yet to be assessed. They are recorded in the suspected land register.
  • Contamination after July 1, 1989 is commonly referred to as new damage . Since the Old Pollution Remediation Act came into force, critical deposits and systems have been subject to strict environmental monitoring , and environmental problems should be identified promptly.

In Austria around 70,000 old sites and deposits are known, of which only around 1,000 (around 2-3%) are likely to represent contaminated sites within the meaning of the contaminated site remediation law. As of January 1, 2019, 304 contaminated sites were identified, 164 of which had been rehabilitated or secured. 1895 areas were registered in the suspected area register.

List of major contaminated sites

The following list gives more extensive and more prominent contaminated sites, as well as those of the highest urgency for remediation measures (priority class 1).

Lower Austria

As of March 1, 2006, 13 of the 56 contaminated sites recorded in Lower Austria had already been remediated, 18 were in progress and the planning was ongoing for 6.

  • Surroundings Vienna:
    • Contaminated site N18 (secured): OMV refinery Schwechat : refinery since 1938; massive contamination during World War II and later leaks; estimated 800,000 m³; since 1988 hydraulic safety measures (groundwater extraction and skimming of oil lenses)
  • Mitterndorfer Senke : Gravel pits that have been backfilled with (partially) groundwater- endangering waste and thus were or are suspected of endangering the groundwater wells of Vienna's third drinking water pipeline .
    • Contaminated site N1 (rehabilitated): Fischer landfill (operator Waxina / Johann Fischer), in Theresienfeld, illegal industrial and commercial waste dumps from the 1979s, with 800,000 m³ the largest contaminated site rehabilitation project in Europe at the time; Permanently closed in 1987, refurbished for € 130 million in 2001–2008.
    • Contaminated site N9 (rehabilitated): Berger landfill (Helene Berger landfill), in Weikersdorf am Steinfelde , gravel pit on the B26 1 km west of the A2 west of Wiener Neustadt, filled with garbage in 1970–1987, reaching into the groundwater, by a consortium with Porr Umwelttechnik GmbH cleared by pretreatment and clearing of 1.15 million t of waste and contaminated subsoil in the summer of 1996–1998, completion after 56 months of construction in 2001.
    • Contaminated site N52 (rehabilitated): Angerler Grube (owner: Alexander Angerler) in Theresienfeld 3 km north of Wiener Neustadt, 150 m south of the Fischer landfill. Gravel pit, which in the 1970s / 1980s was filled in barrels to a depth of 19 m and only 1 m above the highest groundwater level with excavated material, rubble, waste, including dangerous solvents. At times, an (additional) pollution of the groundwater in the effluent with trichlorethylene was found. The affected groundwater body of the Mitterndorfer Senke is of great importance in terms of water management, especially for the wells of the third drinking water pipeline for Vienna. Refurbished by excavating backfill and contaminated subsoil from August 2005 to August 2009.
    • Contaminated sites N55 and N56 (rehabilitated): Garbage pits, concrete pit fields , dug to the southeast of the Fischer landfill as gravel pits before 1945 for the construction of concrete foundations, filled with garbage until the 1970s, including distillation residues and solvents. Despite clearing numerous barrels, contamination of the subsoil, renovation by operating a floor air extraction system since the 2nd quarter of 2009 for a planned 3 years.
    • Contaminated site N6 (priority 2, in progress in 2019): Aluminum slag landfill near Wiener Neustadt , 500 m west of the A2 and 500 m south of the B26, i.e. around 500 m southeast of the contaminated site N9. Various types of waste, predominantly (680,000 t) aluminum dross with water-soluble salt components (chlorides, fluorides), were dumped here from 1974 to around 1990. There is no base seal, groundwater will reach the deepest point of the bottom of the landfill in 3 years, the landfill is covered with topsoil and recultivated. In the reducing atmosphere, gases such as methane, hydrogen and ammonia, which is harmful to groundwater, are formed. In 1991 the contaminated site was given priority class 2 and left in October 2010. In February 2003 the former operator - including the former N9 contaminated site - the sole proprietor Helene Berger died, the descendants did not take over the inheritance, which means that it fell to the state along with the obligation to remediate it. December 2010, the renovation costs are estimated at € 200 million.

Upper Austria

  • Central area (Linz basin – Welser Heide and more direct catchment area):
    • O2 contaminated site (rehabilitated): Kiener landfill (operator Herbert Kiener / Kieba) near Bachmanning: improperly operated hazardous waste landfill from the early 1980s, at that time one of the most dangerous contaminated sites in Austria according to media reports and up to then the largest and most expensive contaminated site remediation in Upper Austria; Refurbishment ordered in 1996, refurbished for € 20 million after the operator went bankrupt in 1998–2001.
    • Contaminated site O44: Linz Chemical Park : Former Linz Chemicals in Linz; largest old chemical production site in Austria (chemical park approx. 85 ha); organic solvents and pesticides from 50 years of production
    • Contaminated site O74 (secured): sewage sludge ponds, regional sewage treatment plant, Asten : Danube near Raffelstetten ; Sewage sludge from a municipal sewage treatment plant; over 300,000 m³ of industrial and commercial waste; 2007–2008 secured, 2015 shown as secured in the contaminated site atlas.
    • Contaminated site O76 (priority 1): Linz coking plant : Voest area in Linz; Contamination with tar oil and aromatic hydrocarbons from 50 years of coke production ; Renovation and safeguarding in progress (2019); up to now € 85 million funding
    • Contaminated site O53 (secured): Gusswerkstrasse landfill in Steyr- Münichholz ; 120,000 m³ of industrial waste and construction rubble; Securing 2001–2002 (together with contaminated site O54 retention basin Gusswerkstrasse ); € 7.5 million funding costs
  • Further:
    • Contaminated site O69 (rehabilitated): Freistadt landfill in Freistadt : Around 60,000 m³ of construction waste, household waste, industrial and commercial waste; Landfill gas problem; Decontaminated by 2011, funding costs € 4.5 million.

Salzburg

The remediation of contaminated sites is well advanced in the state of Salzburg. In 2019, he listed only 7 contaminated sites out of a total of 19 recorded, all of which were of lower priority and had not yet been remedied or secured.

Among other things , the Roseggerstrasse gasworks , the Siggerwiesen landfill and the Glanegg shooting range in and around Salzburg and the Rotgülden arsenic dump in Muhr im Lungau and the Esse Mitterberghütten in Pongau as mining remains have been renovated .

    • Contaminated site W18 (priority 1, in progress) Simmering gas works : considerable tar oil pollution from the operating period 1899–1975 (coal gas and fission gas generation; wartime and accidents); extreme PAH exposure and very high cyanide concentrations.
    • Contaminated site W20 (priority 1, secured, to be carried out in 2019) Leopoldau gas works in Floridsdorf: considerable tar oil pollution from the operating period 1911–1969 (coal gas and fission gas production; wartime and accidents); greatly increased cyanide, PAH15 and benzene concentrations.
  • Landfills (old deposits):
    • Contaminated site W10  WIG 64 Donaupark - Bruckhaufen : old garbage dump of the city of Vienna, from the monarchy to 1963; 5 million m³; Landfill gas and landfill leachate problems; today green areas (Donaupark-WIG 64), sports facilities, the Vienna International Center.
