What this tracks
This dataset predicts the probability that nitrate levels in private wells across Nebraska exceed safe drinking water thresholds (3 mg/L, 5 mg/L, and 10 mg/L).
Why it matters to you
If you rely on a private well in Nebraska, this data helps you decide whether to test your water for nitrates—a common contaminant linked to health risks. A high prediction probability (like 0.71 for the 3 mg/L threshold) suggests your well water may need treatment. Farmers can also use this to assess runoff risks before expanding fertilizer use near vulnerable areas.
How to read this data
GBM_BKD_Prediction — Probability (0–1) that nitrate exceeds 3 mg/L (background level). Sample: 0.71 means a 71% chance.
GBM_ELE_Prediction — Probability for 5 mg/L (elevated level). Sample: 0.33 means a 33% chance.
GBM_MCL_Prediction_Binary — Binary flag (0 or 1) for 10 mg/L (federal safety limit). Sample: 1 means likely unsafe.
