Septic Fields Mimic Graves on GPR

Ground‑penetrating radar cannot reliably distinguish shallow clay‑lined utility trenches from human burials. Absent archival checks for historical infrastructure, GPR 'hits' can be misread as graves and trigger high‑stakes claims that later prove false positives. — This cautions courts, governments, and media against treating preliminary GPR scans as definitive and urges mandatory archival/utilities research before public announcements.
