这项研究加深了对矿泉水足迹，特别是黄金足迹的分析，这些区域的研究不足，自殖民时代以来采矿一直是一种强化的开采活动，如哥伦比亚考卡省北部的情况。因此，目的是估计Suárez（哥伦比亚考卡）金矿开采的水足迹指标，量化生产过程中未回水产生的影响和废水中的污染物水平，旨在加强公共政策、控制战略和缓解措施，减少采矿活动对环境的影响。蓝水足迹估计为每公斤黄金提取79.91立方米，而灰水足迹的范围为每公斤黄金提取272,125.39至404,825.11立方米。所得的水足迹值与其他类似作业的矿山进行了比较。这些结果为决策提供了基准，为环境战略规划和规章提供了要素，并显示了黄金活动对水资源和领土造成的巨大环境压力。Suárez金矿生产的水足迹评价（哥伦比亚考卡）。研究发现，每提取一公斤黄金，灰水足迹在272,125.39至404,825.11立方米之间。黄金生产的灰水足迹比蓝水足迹大得多。金矿开采活动需要环境当局和污染机构的重要管理。氰化物、汞、采矿、用水。
This research deepens the analysis of the mineral water footprint, especially that of gold, in regions that are understudied and where mining has been an intensified extractive activity since the colonial era, as is the case in the northern part of department of Cauca in Colombia. Thus, the purpose was to estimate the water footprint indicators in gold mining in Suárez (Cauca, Colombia), to quantify the impacts generated by the non-returned water in the production process and the levels of pollutants in the wastewater, aimed to strength public policies, control strategies and mitigation that generates reductions in the impacts from mining activities on the environment. The blue water footprint was estimated in 79.91 m3 per kg of gold extracted and the gray water footprint was found to be in the range of 272,125.39 to 404,825.11 m3 per kg of gold extracted. The water footprint values obtained were compared with other mines with similar operations. These results generate a baseline for decision making, providing elements for environmental strategic planning, regulations and showing the great environmental pressure that gold activity exerts on water resources and the territories. Assessment of water footprint of gold production in Suárez (Cauca, Colombia). Gray water footprint was found to be in the range of 272,125.39 to 404,825.11 m3 per kg of gold extracted. The gold production had much larger gray water footprint than blue water footprint. Gold mining activity requires important management by environmental authorities and polluting agents.
