Kriging groundwater levels without normal distribution

[SimonHarper1]

hi,

I'm looking to krige my groundwater levels. When I examine the distribution I notice my data isn't normall distributed and even when I attempt to transform the data I get no improvement (okay maybe a slight improvement on my histogram but none on my q-q plot).  Does that mean I shouldn't krige?

If the other transformations aren't working, try a Normal Score transformation.  It's the default option for simple kriging in the Geostatistical Wizard.

If you're able to send your data to ekrause@esri.com, I can take a look to see if kriging is appropriate here.
