Kriging creating sharp edge interpolation

I am having trouble interpolating groundwater nitrate values using Kriging.  Once I tell the tool to optimize the fit it produces very sharp edges in the spatial domain that I have a hard time justifying using physical concepts.

I was wondering if anybody else has had this issue and how could one deal with this.  I would like to create a more smooth interpolated map if possible.

Attached is the figure I have with the black points indicating the sample points.
