This section displays pollution incidents in groundwater in varying strata. Different plume diffusion means pollutants enter the stream via different routes. Visual examples are given for sandstone, chalk, limestone and poorly permeable strata individually in four stories as well as comparatively in "Pollution plumes in different aquifer types".
