The Ordnance Survey recorded it in gothic lettering as St. Clómaun's Well on both its 1839 and 1925 six-inch editions, a rendering that garbles the original Irish name. Locally, people simply called it St. Clement's Well, as reported in the Wexford People in July 1954, a pronunciation that drifted still further from the source. The name behind the misspelling is Colmán, one of the most common saints' names in early Irish Christianity; there are so many Saint Colmáns documented that it is not possible to say which one was being commemorated here.

The well itself sits at the foot of a steep east-facing slope on the western bank of a wide, north-to-south running river, right at the margin where land meets tidal mud-flats. A natural spring feeds into a stone-lined channel, roughly 0.6 metres wide and 2.1 metres long, directed towards the river. In 1954, a concrete U-shaped wall with a basin and overflow channel was installed just to the south of this older structure, modernising the site in a way that was common for holy wells still receiving some devotion. It was during this 1954 construction work that things became genuinely interesting. Workers uncovered a stone inscribed with the letters RC and the date 1696, along with a second stone bearing the imprint of a human foot, a portion of a cross, and part of what appears to have been a font. Foot-shaped carvings at holy wells are not unusual in an Irish context, sometimes associated with inauguration rites or acts of devotion, but the combination of objects here suggested a site with layered significance going back at least to the late seventeenth century, and very probably much further. None of these stones remain at the location today.
