I have a set of soil-sample data that tracks a subsurface contaminant plume across several boreholes. I need someone fluent with Golden Software Surfer or anyother to turn those raw points into a fully navigable 3-D heat-map style model. Here is what I am after: a volumetric rendering that uses colour gradients to show concentration levels at every interpolated depth. The display should behave like the standard Surfer voxel/3-D view—zoom, rotate, slice—so I can examine hot-spots in cross-section or as an isosurface. While heat-map styling is my first choice, I am open to complementary outputs such as conventional contour slices if that helps illustrate the data. Key details to include • Accurate concentration levels throughout the plume • Clear legend and colour ramp for quick risk interpretation • Clean axis labels, scale bars, and north arrow so the figure can drop straight into a report Deliverables 1. Surfer project file (.SRF) with all grids, layers, and colour settings intact 2. High-resolution PNG (and, if practical, an interactive PDF) of the final 3-D view 3. A brief note on the gridding method and any assumptions so results can be replicated or defended I will supply the XYZ-concentration spreadsheet immediately upon award. If you need additional metadata—coordinate system, borehole IDs, QA/QC notes—just let me know. Turnaround within a week would be ideal, but tell me what is realistic for you.
