Irish President Michael D. Higgins when he visited the island on 1 August 2013 to commemorate the 1450th Anniversary of St Columba's arrival. Saint Columba concerned himself with the physical wellbeing of the local people, identifying and recommending suitable sources of water for them to drink. He used these sources of water for therapeutic purposes and it is known that he provided a health advisory service for all of the inhabitants of the island.

and this makes the water slightly hard (alkaline). The rock structure is typical of the geology of County Antrim that was formed by volcanic activity throughout the region in a bygone age. This can be verified by travelling less than thirty miles (fifty kilometres) to the south east. Here, the landscape is dominated by Slemish Mountain which is situated just outside the village of Broughshane (Bruach Sheáin in Irish and pronounced bru-SHAYN). Slemish Mountain has a height of approximately 1500 feet (437 metres) and is actually the dormant plug of an extinct volcano . Today, Slemish Mountain is more famous for being the home of
Saint Patrick after he was taken to Ireland as a slave and tasked with tending sheep and pigs around 405 AD.

In 2013, just one remains and it stills draws all of its process water from Saint Columb's Rill but it has shifted its energy dependence from turf to natural gas.

grist. Through heating, the water loses its temporary hardness (alkalinity) and becomes soft (acidic). This is because the hydrogen carbonate ions (HCO3–) decompose to form carbonate ions (CO32–) that react with the dissolved calcium to form precipitates of calcium carbonate. In the production of
Jim Beam Bourbon, the 'Sour Mash' process is used to add acidity and this process is a requirement for Tennessee Whiskeys such as
Jack Daniels but this technique is not required at Bushmills.
All of the whiskeys released by the Old Bushmills Distillery contain Saint Columb's Rill water and this water of life (uisce beatha in Irish) is distributed throughout the world by its parent company
Jose Cuervo. Bushmills Whiskey sold 9.6 million bottles in 2012-2013. Bushmills were owned by
Diageo until 2015 when they were bought by Jose Cuervo.

This is in keeping with the practise of Saint Columba more than 1,400 years ago when he concerned himself with the spiritual and physical wellbeing of everyone he ministered to.
