Groundwater development at Lamlash and Glen Rosa, Island of Arran

In April 1982 a water well was drilled into superficial deposits
to the west of Lamlash village on Arran in order to augment the existing
public supply. This borehole was pump tested for a short period and had
3
a specific capacity of 23 m /day/m, a value considerably higher than for
other water wells on Arran, drilled into sandstone bedrock. Details of
the borehole construction are given in Ball and Harrison (Hydrogeology
in Scot. 83-2) .
During 1983, prior to commissioning, this borehole was vandalised,
causing its abandonment. However, the results were promising enough to
make worthwhile the drilling of a second borehole at the same site in
September 1984, along with an exploratory borehole into superficial deposits
in Glen Rosa, to the west of Bradick. This report presents details of
borehole construction and pumping tests carried out in both boreholes
