Selection follows a fixed set of rules applied to local records: signals such as PFAS detections, lead action-level exceedances on record, a large share of pre-1978 housing, EPA Radon Zone 1, or a top flood or wildfire risk each add a related guide, and when none applies, general water testing and filtration guides are shown instead.
