Ballygowan Water Source

What Makes Us Unique

Ballygowan Water has a unique mineral content, the result of 750 years of natural filtration through mineral-rich limestone. It is these minerals that give Ballygowan Water its uniquely refreshing taste. You can see the Mineral Composition broken out below.

Geological Origin

The Ballygowan source is located within ancient Carboniferous limestones of South West Limerick, Ireland. The water of the source emerges at the surface from a Well that is over 235 metres (770 feet) deep. Scientific studies have shown that this water can take up to 750 years to percolate through the 355 million year old limestones and dolomite fractures and joints before being drawn to the surface. The Ballygowan source emerges at a temperature of 14.6 C (58.3 F) having percolated, for centuries, a distance of over 29 km (18 miles), to a depth of 235 metres (770 feet) through these ancient rocks. The groundwater dissolves the minerals out of the limestones and dolomites to give Ballygowan its particular hydrochemical attributes.

Hydrogeological Model

Rainfall, drifting in from the Atlantic Ocean to the West, falls on the uplands of Carrigkerry and Knockaderry before infiltrating into the ground as recharge and moving downgradient to the source. The groundwater, over the hundreds of years, moves from the East and West through fissures and faults in the limestones and dolomites beneath thick glacial and alluvial deposits. The water percolates downwards beneath the protective strata of Namurian shales, picking up calcium and magnesium, potassium and sulphates, bicarbonate and other salts. The groundwater eventually emerges in the Ballygowan source in the centre of the Newcastle West syncline.
