Analysis of precipitation and recharge of aquifers in Tota and Ibagué (Colombia) from stable isotopes (18O and 2H)

| description | Identifying the hydraulic connection between the area of recharge and the area of discharge in aquifers is only possible by using tracers; the 18O and 2H isotopes have proven to be good tracers to determine such hydraulic connection. It is assumed that in Ibagué and Lake Tota the recharge of the aquifers is given by two processes: vertical infiltration and precipitation, and infiltration in the high mountains followed by regional permeation that reaches the aquifers in the lower part. In Tota, the delta (δ) values of 18O are lower in the higher part than in the lower part: in the higher area, the values are close to -10 ‰, while in the lower area they are close to -3‰. In Ibagué, the delta values (δ) of 18O are also higher in the lower part: in the upper area the values are between -8 and -11 ‰, while in the lower area are between -7 and -9 ‰. In both cases, the isotopic difference between the upper and the lower areas could indicate that not all the water recharge in the lower area comes from precipitation in the high mountains, but that additional recharge can be the product of precipitation and infiltration in the lower part. |

In Tota, the delta (δ) values of 18O are lower in the higher part than in the lower part: in the higher area, the values are close to -10 ‰, while in the lower area they are close to -3‰.

Reconocer la conexión hidráulica entre la zona de recarga y la zona de descarga en acuíferos solo es posible mediante el uso de trazadores, y los isótopos de 18O y 2H han probado ser buenos trazadores. En Ibagué y el lago de Tota se supone que la recarga de los acuíferos en la parte baja se da no solamente por infiltración vertical directa, sino también por precipitación e infiltración en las montañas altas, para luego infiltrarse regionalmente hasta alimentar los acuíferos en la parte baja. En Tota, los valores delta (δ) para el 18O son más ligeros en la parte alta que en la parte baja; en la parte alta los valores están cerca de -10 ‰, mientras que los de la parte baja están en torno a -3 ‰. En Ibagué, los valores δ para el 18O son, igualmente, más bajos en la parte alta que en la parte baja; en la parte alta están entre -8 y -11 ‰, mientras que en la parte baja están entre -7 y -9 ‰. En ambos casos, la diferencia isotópica entre los valores de la parte alta y los de la parte baja podría indicar que no toda la infiltración de los acuíferos en la parte baja proviene de la recarga por la precipitación en la parte montañosa alta, y, por lo tanto, esa recarga adicional sería producto de la precipitación y la infiltración en la parte baja.
