	Major public supply groundwater abstractions from the Jurassic aquifers are found in the Malmesbury area, and surface water abstraction from the River Avon takes place in the region of Bath. These provide water to a large part of the district including the city itself. Abstraction has raised concern about river levels in late summer, and as a consequence groundwater is used to support streams and rivers during low-flow periods. Details of groundwater and surface water abstraction and licences can be found in the Environment Agency CAMS (Catchment Abstraction Management Strategy) documentation for the Bristol Avon.

	The famous hot springs of Bath are one of only five groups of thermal springs in the UK, and the only that qualify as ‘hot’, emerging at a temperature of about 45°C with a combined flow of about 15 litres per second (Stanton, fig. 8.3 in Kellaway, 1991)<ref>Kellaway, G A (editor). 1991.

The King’s, Cross Bath '''(Figure P785919)''' and Hetling springs, all of which are found within a small distance of each other in the centre of the city, would in their natural state have risen to the surface through the Charmouth Mudstone bedrock and the terrace gravels of the River Avon. They were discovered by the native Britons, perhaps as long ago as 863 BC, when it is reputed that their healing powers cured a Celtic prince of leprosy. A shrine, dedicated to the local water goddess Sulis, was in existence at Bath at the time of the Roman conquest of AD 43; from this the Roman town derived the name Aquae Sulis. The Romans identified Sulis with their goddess Minerva, responsible among other things for medicine, and they first began to develop the bath-house complex soon after the conquest of Britain, possibly during the reign of the Emperor Claudius (AD 41–54). The baths fell into disrepair following the collapse of the Roman Empire, but were rebuilt in association with renewed interest in bathing waters during the 18th and 19th centuries (cover photograph). In 1810, the springs diverted and failed, and it was none other than William Smith who restored the water to its original course. Today, the springs and bath houses form a major British tourist attraction.

	Like all the other British thermal springs, including Hotwells in the adjacent Bristol district, the waters at Bath are sourced in the Carboniferous Limestone Supergroup, which lies beneath the city at depths as shallow as 50 m below ground level '''(Figure P785919)'''. It is widely accepted that rainwater falling on the Carboniferous Limestone outcrop in the Mendip Hills, south of the district, descends to great depths in the Radstock Basin where it becomes geothermally heated, before rising beneath Bath and breaking through the aquiclude formed by the Mesozoic rocks. The nature of the conduit to the surface is more controversial: Andrews et al. (1982) favoured a fracture zone over a Variscan thrust fault, and Kellaway (1996)<ref>Kellaway, G A. 1996.
