How The Hot Springs Form At Bath
The water which bubbles up from the ground at Bath fell as rain on the nearby Mendip Hills. It percolates down through limestone aquifers to a depth of between 2,700 metres (8,900 ft) and 4,300 metres (14,100 ft) where geothermal energy raises the water temperature to between 64 °C (147.2 °F) and 96 °C (204.8 °F). Under pressure, the heated water rises to the surface along fissures and faults in the limestone. This process is similar to an artificial one known as Enhanced Geothermal System which also makes use of the high pressures and temperatures below the Earth's crust. Hot water at a temperature of 46 °C (114.8 °F) rises here at the rate of 1,170,000 litres (257,364 imp gal) every day, from a geological fault (the Pennyquick fault). In 1983 a new spa water bore-hole was sunk, providing a clean and safe supply of spa water for drinking in the Pump Room.

Famous quotes containing the words hot, springs, form and/or bath:
“When hot dogs like Mr. D’Amato or the Republican apologist Roger Ailes say that Whitewater is worse than Watergate, it’s because they’re suffering from a disease. It’s called bull-imia, and it’s the regurgitation of patent hyperbole.”
—Anna Quindlen (b. 1952)
“In short, as a snow-drift is formed where there is a lull in the wind, so, one would say, where there is a lull of truth, an institution springs up. But the truth blows right on over it, nevertheless, and at length blows it down.”
—Henry David Thoreau (1817–1862)
“Here form is content, content is form.”
—Samuel Beckett (1906–1989)
“I think sometimes, could I only have music on my own terms; could I live in a great city and know where I could go whenever I wished the ablution and inundation of musical waves,—that were a bath and a medicine.”
—Ralph Waldo Emerson (1803–1882)
