I am trying to put a spatial distribution map showing the concentration of identified organic compounds for sampled groundwater wells.  Sampling locations are clustered yet scattered. What would be a good interpolation method (idw, kriging, nn) to produce a good map? The concentration values have nonlinear distribution with few outliers. Can you please suggest?
