than can be expected to originate from the cauldrons, three to four times the
wa-
ter equivalent of the accumulation of snow over the watershed of the cauldrons. It has

2–
5 m3 s 1 at maximum (Vatnaskil, 2005). It is possible that part of the sulfate-rich
groundwater from the glacier comes from the cauldrons
