A report on soil contamination is a condition for the purchase of the Sineu mines.

SinedThe Catalan government is awaiting a report from Endesa, the company that owns the Sineu mines, before proceeding with the purchase. This information has been obtained.All PlansThe administration does not want to purchase the pond and the property without a certificate confirming that the land is not contaminated. The purchase appears to have been delayed by the Ministry of Agriculture, Fisheries, and Natural Environment due to the owner's failure to obtain this certificate. Government sources want to ensure the purchase of this land without having to incur further expenses to decontaminate it, should the contamination levels be higher. It's worth recalling that the purchase of this wetland, located on the road between Sineu and Maria de la Salut, was approved by the Parliament of the Balearic Islands following a non-binding resolution presented by Member of Parliament Pedro Álvarez. As explained by Sineu councilor and MP Pedro Álvarez, "this area, abandoned in the 1980s with the decline and disappearance of the mining industry, has become, over time, a wetland and forested environment rich in biodiversity." This area is included in the Balearic inventory of wetlands and, according to the World Wildlife Fund (WWF Spain), is a site of high biological importance. The area is intended to be used as a recreational space, and in addition to the portion owned by Endesa, there are other lands belonging to families in Sineu who have already approved the purchase. The pond formed in the former Fangar lignite mine, within the municipality of Sineu, has become established over the years as a wetland of environmental interest in the interior of the Pla de Mallorca. The mine, owned by Endesa, was active between 1982 and 1987 and was abandoned due to water seepage from the aquifer, which led to the formation of the current pond. With an area of approximately two hectares and a permanent freshwater source, the site is included in the Balearic Inventory of Wetlands as a mining pond and has been designated by the Sineu City Council as an Area of Singular Landscape Interest. Despite its artificial origin, the pond supports riparian habitats and diverse species of flora and fauna, such as tamarind trees, reeds, and breeding birds like the moorhen, coot, and grebe. Endesa has carried out environmental restoration work, including the removal of mining debris and the improvement of access. Despite its high biological value, as considered by the World Wide Fund for Nature (WWF), the site does not yet have any protected status as a natural area.
