Het gebied is laaggelegen (&lt; 400 m) maar heeft steile hellingen. Het gebied heeft een lange geschiedenis van mijnbouw sinds de Romeinse tijd, maar in de tweede helft van de 20e eeuw werd de impact van de mijnbouwactiviteiten intenser. Tussen de jaren 1950 en 1991, toen de activiteiten stopten, werden enorme hoeveelheden metalen ertsen verwerkt, wat leidde tot de productie van duizenden miljoenen tonnen mijnafval. De meeste van deze afvalstoffen werden verlaten met het einde van de mijnbouwactiviteit. Er zijn weinig pogingen ondernomen om het gebied te herstellen, wat heeft geleid tot een bron van metalen en metallo\u00efden voor de omliggende gebieden door water- en\/of winderosie.<\/p>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n<div class=\"group-wrapper\">            \r\n            <div class=\"icon-and-text icon-and-text-1\">\r\n                                    <div class=\"image-box\">\r\n                        <img decoding=\"async\" src=\"https:\/\/soilprom.eu\/wp-content\/uploads\/2025\/03\/PFAS-3.png\" alt=\"Cartagena &#8211; La Uni\u00f3n Mining District image\">\r\n                    <\/div>\r\n                \r\n                                    <p class=\"text\">Verlaten landbouwgebieden\/bosgebieden\/peri-urbane gebieden<\/p>\r\n                            <\/div>\r\n            \r\n                        \r\n            <div class=\"icon-and-text icon-and-text-2\">\r\n                                    <div class=\"image-box\">\r\n                        <img decoding=\"async\" src=\"https:\/\/soilprom.eu\/wp-content\/uploads\/2025\/03\/PFAS-2.png\" alt=\"Cartagena &#8211; La Uni\u00f3n Mining District image\">\r\n                    <\/div>\r\n                \r\n                                    <p class=\"text\">Metalen en Metallo\u00efden <\/p>\r\n                            <\/div>\r\n            \r\n                        \r\n            <div class=\"icon-and-text icon-and-text-3\">\r\n                                    <div class=\"image-box\">\r\n                        <img decoding=\"async\" src=\"https:\/\/soilprom.eu\/wp-content\/uploads\/2025\/03\/Use-case-icon-3-1.png\" alt=\"Cartagena &#8211; La Uni\u00f3n Mining District image\">\r\n                    <\/div>\r\n                \r\n                                    <p class=\"text\">Bodem, water en lucht<\/p>\r\n                            <\/div>\r\n            \r\n            <\/div>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading has-black-color has-text-color has-link-color wp-elements-9da1092ba9213ccb1144e0f42a68d06e\"><strong>Proces<\/strong><\/h2>\n\n\n\n<p>Biogeochemie van metalen in de bodem.
