An in situ cylindrical porewater sampler, with interval stackers and a nondegradable membrane, is described. Both horizontal and vertical gradients of dissolved constituents in porewater can be assessed. Sampling at 4-cm intervals within Myriophyllum spicatum root zones showed that steep depletion contours of dissolved phosphate occur, delimiting the zone of root influence.
