Etymologically, the entry records: From ground + water. Root origin matters for spelling because borrowed morphemes (Greek, Latin, Old French, Old English) carry their source-language orthographic conventions into modern English, which is why historical etymology is often the cleanest predictor of whether a cluster like "-ough", "-eau", or "-tion" will appear. For readers arriving here from a spelling check, the authoritative guidance is: the correct English form is groundwater, spelled G-R-O-U-N-D-W-A-T-E-R, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
