Water Marks in carpet after encapping?

[encapman]

Joel may be right. It does look kind of like "shading" or "pooling" in the picture. Joel described that characteristic correctly. If that is in fact what you're dealing with (it's very hard to tell for sure from a photo),  re-wetting, and grooming may help the condition. But it may just take some time walking on it to smooth out the appearance. And it may be non-correctable, because "shading", "pooling", "water marking" can be a condition of the carpet itself (not a cleaning error); and that condition can often impossible to correct.  

Here's a link from the Carpet & Rug Institute explaining this phenomenon (if that is in fact what you're looking at)...
