黄金开采是哥伦比亚氢气资源污染的主要问题之一，这一做法对水质产生了很大影响，因为在开采过程中会积累废物。在这项研究中，对四条采金河流和一条考卡河的五条天然河床的水质进行了评估，每次作业在Dios Te Dé、Tamboral、Piedra Imán和Lorenzo溪流的进水口之前和出水口之后采集样本，这些溪流受到手工采金劳动力的影响，排入哥伦比亚苏亚雷斯考卡市考卡河上的塞尔吉纳水库。采用哥伦比亚的污染指数对溪流中的水体进行了表征。使用IDEAM协议作为监测水流的指南。在三个时期内，在这些热带生态系统中有作业的天然河床上的15个站点和水库后的高加河上的一个采样站进行了采样；2018年和2019年分别采集了两个和一个采样站。考虑了污染指数随环境变量的变化范围。结果表明，与TSS、TUR和Hg相关的污染物在作业输出的采样站和对作业有影响的溪流(T3、T4、I2、I3、D2和D5)中含量较高。根据ICA IDEAM指数，不同采样站的水质得分在可接受和正常之间变化。然而，高加河C1采样站的汞浓度是由于合并过程中的作业造成的。这需要社区、矿工、作业所有者和控制机构，如高加索地区自治公司(CRC)和环境与可持续发展部(MADS)进行战略干预，以最大限度地减少对氢气资源和与这种资源相关的生态系统服务的负面影响。水质指标；手工采金；溪流；作业；汞；物理化学变量
Gold mining is one of the major problems of contamination of hydric resources in Colombia, this practice generates a high impact on water quality due to the accumulation of waste during its process. In this study water quality was evaluated in five natural stream beds corresponding to four streams with gold mining operations and one in the Cauca River, taking samples before the water inlet and after the outlet in each operation in the streams of Dios Te Dé, Tamboral, Piedra Imán, and Lorenzo affected by artisanal gold mining labor, which drain into the Salvajina Reservoir on the Cauca River in the municipality of Suárez Cauca, Colombia. Characterization of water bodies in the streams was carried out applying contamination indices of Colombia. The IDEAM protocol was used as guide to monitor the water currents. Samples were taken in 15 stations in the natural stream beds with operations and a sampling station on the Cauca River after the reservoir in these lotic ecosystems, during three periods; two from 2018 and one from 2019. The range of the contamination indices according to the environmental variables were considered. Results show that the contaminants associated with TSS, TUR, and Hg are high in the sampling stations in the output of the operations and the sampling stations of the streams with influence on the operations (T3, T4, I2, I3, D2, and D5). The water quality score according to the ICA IDEAM index varied between acceptable and regular in the different sampling stations. However the Hg concentration in sampling station C1 of the Cauca River is due to contributions from the operations in the amalgamation process. This requires strategic interventions by the communities, miners, operation owners, and control organisms as the Regional Autonomous Corporation of Cauca (CRC) and the Ministry of Environment and Sustainable Development (MADS) to minimize the negative impacts on the hydric resource and ecosystemic services associated with this resource.
