Chondrite-normalized REE patterns of the unfiltered groundwater and filtered groundwater with different pore sizes. Chondrite data are from Anders and Grevesse ([1989]). Unfiltered (circles), 0.2 μm (triangles), 10 kDa (squares), and 1 kDa (inverted triangles) in the (a) 09MI20 and (b) 10MI26 boreholes.
