Researchers from the UPCT conclude that, despite everything, there is no indication of risks to the aquifer, after studying the subsoil of 8 pig deposits
The Group of Management, Use and Recovery of Soils and Waters of the Polytechnic University of Cartagena (UPCT) presented yesterday the results of the first year of studies to analyze environmental management for intensive pig farming. The analysis of eight ponds that accumulate slurry from the farms located in Fuente Álamo reveals the need to monitor leaching, since “they are not completely waterproof”, although it concludes that “they have not reached the level of the subsoil in which the aquifer that flows into the Mar Menor ».
The investigations carried out by the Chair promoted with the Fuentealamero City Council, however, highlight the convenience of being able to install a piezometer in the ponds to monitor the possible leaching annually.
It must be taken into account that the UPCT researchers, led by Ángel Faz Cano, have studied in detail the eight storage and drying ponds referred to, on which they have concluded that, in all of them, the underlying materials are not completely waterproof and that there are indications of slurry leaching, but at depth levels that would only exceptionally reach 6-8 meters, while the aquifer in the studied area is at least forty meters below.
They consider that the affection by the storage of by-products in the farms is “very superficial”
In the conclusion presented, he points out that “the affection to the subsoil is considered very shallow and there is no evidence of risk to the aquifer”, summarizes the professor from the UPCT. The studies have followed the parameters of the Mar Menor Recovery and Protection Law and the Technical Instruction on Prevention and Control of Soil Pollution of the Autonomous Community.
The presentation of the results, an act chaired by the mayor of Fuente Álamo, Juana María Martínez, was attended by the Minister of Water and Agriculture, Antonio Luengo, and the General Director of Livestock, Francisco Espejo.
