Description A historical pile at Kaňk close to Kutná Hora was investigated with an objective to determine stability of secondary minerals. The most stable phases are scorodite and beudantite. In contrast, As in jarosite and Fe(III)-oxyhydroxides is more mobile. Pollution by As is not alarming, but monitoring of the site is required.
