This study aims to determine the quality and status of water quality and environmental quality index in river waters around the coal mining area. This study is an observational study with a descriptive design. After the observation, the data were analyzed in the laboratory. The results were then described. The data analysis technique used was descriptive analysis, which compares the results of laboratory tests from each sample that have been calculated based on the value of the water parameter with water quality standards through assessment of environmental quality referring to the criteria for class II water quality standards, water quality status with pollution index method and environmental quality index. The quality of river water around the coal mining area has decreased which is indicated by the water quality parameter that has exceeded the water quality standard of 16.57-25% and still meets the water quality standard of 75-83.33%. The status of the quality of river water around the coal mine using the Pollution Index (PI) method indicates that it has been moderately to heavily polluted. The Environmental Quality Index (EQI) based on the Water Quality Index (WQI) for river waters around the coal mining area in general is of the quite good criteria.
