Abstract

Summary

The production of potash as a key fertilizer generates gangues rich in sodium salts that are usually stored as large surface stockpiles. Stockpiles contain more than 90% of salts, which can be a future economic resource (saline deposits).

ICL Iberia manages salt deposits in NE of the Iberian Peninsula which requires an adequate research program for avoiding environmental impacts on water bodies. The objectives are minimize the entrance of fresh water into the system, the properly management of saline waters and preserve the future use of salty materials. For that reasons, ICL Iberia is developing a management plan that includes the use of the best available techniques for both preventive and corrective measures.

For the evaluation and design of the preventive and corrective measures, a detailed geological and hydrogeological characterization of the subsoil has been carried out using direct and indirect techniques.

The direct techniques, such as borehole sampling and execution of well pumping and recovery tests, are essential for performing an accurate characterization. However, the use of indirect techniques, such as ERT has shown its utility to provide very valuable information in a non-destructive manner, minimizing drilling works and the risk of putting in contact different water bodies.
