Buštěhrad slag heap (Czech: ''Buštěhradská halda''; asl) is a huge artificial hill between municipalities of Kladno-Vrapice, Buštěhrad and Stehelčeves near Kladno in the Central Bohemian Region of the Czech Republic that have arisen in the late 20th century as a dumping site for slag from the Kladno ironworks, and other industrial waste. This is one of the most massive heaps of Kladno area, which, particularly when viewed from the northeast, forms by far visible and noticeable part of the landscape in shape of a mesa. The heap is situated less than NE from the centre of the Kladno on right slope of shallow valley of the Dřetovický potok stream, in a place where borders of the three municipalities meet. Most of the heap (NE and central part) is based on cadastre of Stehelčeves. Southern part of it is on territory of Buštěhrad town. Both these settlements lie within a few hundred paces from the heap. Western part of the heap reaches the territory of the city of Kladno, specifically its suburb of Vrapice, just above the medieval church of St. Nicholas and municipal wastewater treatment plant. The heap covers a territiry of approximately 55 hectares and has shape of a trapezoid, slightly stretched on the south. Dimensions are 800 × 600 m, on a diagonal about 1 100 m. Its height varies depending on the surrounding terrain - from the southern side it is a little over 20 meters and on the north heap rises above bottom of the valley for nearly 70 m. The main, approximately trapezium body of the heap is extended vy a minor salient in the northwest in the northwest. This is the only active section of the heap at the present time. All the rest of the body is no longer in use, its overall size does not increase in any way. The core business of the heap, founded after the World War II, in 1950s through 1980s. Rail siding, which is connected to Kladno industrial complexes, bridges the local road Vrapice - Buštehrad the southwestern edge of the heap. From this point took place gradually and enlarging body. According to current estimates, the heap contains about 23 to 27 million tons of materials - blast furnace and steelmaking slag and sludge treatment, cogeneration ash, cinders, sludge from wastewater treatment plants. And less were placed there, both free and in barrels, hazardous waste, including lead-containing or cyanide. Public outrage (later supported by the media attention when a popular magazine Mlady Svet/Young World) created in 1988 case where a group of children from surrounding villages climbed on to play on Bustehrad heap poisoned unconsciously. This fact only speeded up the ongoing downturn operation and reclamation of the heap. Late 80 and early 90 years, so most bodies were covered with clay. Man-shouldered green too soon faded, but during the ensuing year, the nature itself and began to advise on the slopes of the heap is becoming too strong. Originally aligned with the surface become slightly curved as a result of different materials placed in heap. Now most cover heaps wild vegetation, gradually trees grows here. The heap is becoming as living place for wild animals, especially hares and pheasants, its role in the surrounding countryside is even compared to nearby natural monument Vinarice mountain. At present time, heap doesn't represent for people around some inconvenience, no more significant spreading of dust, toxins, etc. This positive fact probably contributes strongly alkaline environment heap leaching of pollutants. There are no studies that would provide accurate information about the composition inside the heap, and the ongoing processes there and help predict future activities inside head. Bustehrad Heap got attention again between 2005 and 2006, when its owner, the company REAL Kladno Leasing Ltd., came up with a plan to progressively to extract part of heap and utilize (especially steel plant slag) for construction and other materials (a process will be lasted 18 years and the public purse would be cost 10 to 15 billion Czech crowns). Realization of this plan was not started, because resist of residents of not only neighboring the villages.
