Transformation inflated with 0's

I am having an issue with attempting to use krigging on a dataset I have.  My data is not normally distributed and it is seriously 0 inflated.  I want to normalize it in order to use krigging, but because I have 0 values, my only option is to use a Normal Score transformation using simple krigging, however, even that doesn't seem to be helping much.  Is there any suggestions anyone can give me to normalize my data, or other interpolation options that might be better suited to my data?

Thank you in advance for your help.
