About

Lead service lines deliver water to homes. The EPA's Lead and Copper Rule requires utilities to inventory and replace all lead lines within 10 years — but most utilities don't know where their pipes are.

This XGBoost model predicts lead pipe probability using year built, housing type, soil corrosivity, and plumbing permit history — trained on Chicago's published inspection results.
