Environmental factors and the development of Bath Spa,England

Thermal water springs at Bristol and Bath in west England have come under close scrutiny since the closure of Bath Spa in 1978. In order to protect the hot springs from dewatering and loss of pressure due to largescale quarrying and deep drilling, it is necessary to identify the sources and routes whereby the thermal water travels to its resurgences in the Avon valley. Control over deep water movements is exercised by the structure and size of the aquifers and aquicludes, modified by zones of Quaternary—Recent fracturing along which water movements have not been restricted or blocked by mineralization.
