Our water is part of the earth’s hydrologic cycle, which is the continuous circulation of moisture and water on our planet. This cycle is in constant operation, moving water from the earth to the atmosphere by evaporation and back again to the earth’s surface as precipitation.
Of the water that falls to the earth’s surface in the form of rainfall, some runs off the surface, some evaporates back to the atmosphere and some infiltrates into the ground. Part of the water that moves into the ground is taken up by plant roots and re-enters the atmosphere through transpiration. The rest percolates deeper into the earth and becomes ground water. This water is held in aquifers and it from these that we pump.
The word aquifer comes from the Latin words aqua, meaning water, and ferre, meaning to bear or carry. Thus an aquifer is a water-bearing geologic formation. An aquifer may be a layer of gravel or sand, a layer of sandstone or limestone, or even a body of massive rock, such as granite, which has sizeable cracks and fissures. Some of the most productive aquifers in Far North Queensland, like ours, consist of sedimentary rocks such as limestone, dolomite and sandstone and these contain naturally occurring minerals in varying concentrations that give our water its unique characteristics.
Our water is analysed by an independent NATA-certified laboratory.
