Abstract: On the basis of hydrogen and oxygen isotopes,recharge and flow mechanisms of groundwater in south piedmont plain of Taihang Mountain were studied,and influences of human activities on groundwater were elucidated. Results indicate that( 1) Isotopic compositions of different water bodies are variable. The average values of δD,δ18O,d-excess and T are-74. 1‰,-9. 5‰,1. 5‰ and9. 34TU for deep groundwater,respectively,-72. 1‰,-8. 8‰,-1. 9‰ and 17. 46TU for shallow groundwater,-69. 3‰,-9. 1‰,-0. 4‰ and 18. 57TU for surface water,and-68. 6‰,-7. 3‰,-10. 7‰ and 20. 18TU for industrial waste water,respectively;( 2)Annual values of δD,δ18O and d-excess of deep groundwater located in recharge area are-68. 08‰,-9. 24‰ and 5. 84‰,respectively,-62. 30‰,-8. 50‰ and 5. 66‰ for groundwater in runoff area,and-75. 14‰,-10. 26‰ and 6. 94‰ for deep groundwater in discharge area,respectively.( 3) Deep groundwater is recharged by local atmospheric precipitation and surface water,meanwhile polluted by surface water derived from sewage and industrial waste water through the fissure zone in the faults. Shallow groundwater is recharged by rainwater and river water,and polluted by filtration of sewage and industrial waste water; and( 4) Deep groundwater with negative d-excess values and high T contents has been effected by sewage and waste water which not only have more negative d-excess values but have high T content. So d-excess values and T contents could be combined as good indicators for groundwater pollution processes research.
