Try Bob Fabian at the OWRB. They used to user Surfer. I believe it only had
the krieg algorithm

I'm doing point to raster interpolations from monitoring well data, and I'm
trying to interpolate water level elevations and nitrate levels. I've been
using the ArcGIS 3D-Analyst Interpolate to Raster function, but there are
several different methods available for this: IDW, Spline, Krieg and Natural
Neighbor.

>From my testing and reading it looks like the Spline method gives good
results when set to "tension" with 3 sample points.

Has anyone done this type of analysis before and have experienced knowledge
to offer?

Thanks,
