ABSTRACT
Mining is the extraction of valuable and economically valuable mineral deposits from the earth's crust, either mechanically or manually, on the surface, below the earth's surface, or below the water surface. Wastewater from large quarry mining activities generally contains suspended solids (mud/sediment), heavy metals, pH changes, and possibly certain chemicals used in the processing. Data analysis was conducted using the Pollution Index (PI) to develop a Surface Water Management. The results of the Pollution Index (PI) analysis showed that all monitoring points were polluted and did not meet water quality standards. The upstream point has an IP of 4.23 (slightly polluted), while the other three points-the reservoir (5.81), middle (6.66), and downstream (5.36)-are classified as moderately polluted. The increase in IP values from upstream to downstream indicates an increase in human activity along the river.
