Resumen
El trabajo comprende un estudio ex post con el objetivo de evaluar los impactos ambientales del predio Garofalo Velasco Jesús Edison, que corresponde a pequeña minería de áridos y pétreos. El análisis de datos de precipitación revela alto riesgo de erosión en las riberas del río San Antonio debido a la lluvia, con posible arrastre de contaminantes hacia fuentes de agua, generando erosión, inestabilidad en el terreno que afecta la geomorfología del área. A su vez se evidenció durante la temporada seca un aumento en la cantidad de sedimentos presentes que afecta a la calidad del agua y provoca la muerte de especies acuáticas. Los materiales y métodos utilizados son: valoración de impactos ambientales mediante Matriz de Leopold. La información en cuanto al área de influencia y estudio fue obtenida mediante GIS. Para el análisis comparativo con la Normativa Ambiental vigente se elaboró una Matriz de evaluación para determinar el nivel de cumplimiento. En base a las observaciones encontradas se estableció un PMA con sus respectivas medidas para compensar los impactos encontrados. Es posible atenuar los efectos negativos de la actividad acatando la normativa vigente con la supervisión del cumplimiento de las medidas correctivas y de mitigación establecidas en el PMA.
The work includes an ex post study with the objective of evaluating the environmental impacts of the Garofalo Velasco Jesús Edison property, which corresponds to small-scale aggregate and stone mining. The analysis of precipitation data reveals a high risk of erosion on the banks of the San Antonio River due to rainfall, with possible dragging of contaminants towards water sources, generating erosion and instability in the terrain that affects the geomorphology of the area. During the dry season, there was also an increase in the amount of sediment present, which affects water quality and causes the death of aquatic species. The materials and methods used are: environmental impact assessment using the Leopold Matrix. The information regarding the area of influence and study was obtained through GIS. For the comparative analysis with current environmental regulations, an evaluation matrix was prepared to determine the level of compliance. Based on the observations found, an EMP was established with the respective measures to compensate for the negative impacts. It is possible to mitigate the negative effects of the activity by complying with current regulations and monitoring compliance with the corrective and mitigation measures established in the EMP.
