It is now relatively (technically) easy to combine field observations with remote sensing, climate, terrain, or other predictor layers and fit a strong machine learning model. The harder question is whether the resulting map is reliable, transferable, and reproducible. In our paper,… ## [Year Two Opens With the Receipts: TWW’s Path to the Edge, in Documents and Charts](https://trentonwaterworks.substack.com/p/year-two-opens-with-the-receipts) _2026-08-11 · Marc L · From the Mains of Trenton_ TWW is closer to insolvency than anyone at City Hall wants to say out loud — and its fallback plan is a state rescue or spending cuts.
