Résumé:
The work has the objective to monitor the evolution of the electric condutividade of the
water (CE) and the dynamic level of the wells used for irrigation that explore the water-bearing one of
the Jandaíra Calcareous rock, located in the Chapada of the Apodi. The 60 wells had been carried
through two visits, of which in 44 the CE of field had been gotten the referring data and in 32 wells the
data of dynamic level. 1ª collects of data was carried through in the period September to the November
of 2005 (after rains) and 2ª collection became fullfilled in the period of January the March of 2006
(before rains).. At the moment of the collection they had been determined the temperature with aid of
pocket thermometer, the CE (electric condutividade) with condutivímetro of pocket of precision and
the dynamic level, with I assist it of the level measurer. The 1,5 had increment in the number of wells
with the intervals of the CE between 1,0; 3,0 4,0 and 4,0 the 5,0 dS/m. Half of the wells the 3,0 had
almost presented CE between 2,0 dS/m, which mativeram the constant CE in período. It found -if the
increase in the depth of the dynamic level of the majority of the wells.
