Abstract
A temporal evolution in fluid composition has been noted during exploitation of the Serrazzano geothermal area, on the northwestern margin of the Larderello field. Strong variations have been recorded in the contents of NH3 ,H3B03 , HC1 and the uncondensable gases. The largest variations were recorded in the 1955-70 period, when new boreholes were being drilled. One possible explanation of these changes may lie in the fact that the fluid discharged from the wells comes from diverse sources and that exploitation has gradually modified the contribution from each of these sources.
