Deep polder Horstermeer invokes groundwater flow from higher level lakes through peat. Oxidation by pyrite releases As, which accumulates in the sludge in the ditches in the low lying polder that receives the groundwater

Polder was put dry (1870) after a lakes was created by mining of torf during previous centuries
