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.
