The present study focused on environmental impact assessment (EIA) due to aggregate quarrying and crushing activities at four selected mining/crusher clusters in the middle catchment of Dwarka river basin of Eastern India. EIA is done both spatially and cluster wise considering the impacts of 10 number of influencing factors on 12 number of environmental components. Simple composite, AHP-based fuzzy and PCA-based fuzzy logic EIA models identified highly impacted zones in different clusters. Accuracy assessment is done using eight parameters and the accuracy assessment of the used models suggested that PCA based fuzzy logic model identified the impacted zone more accurately. Folchi model identified 19 factor-specific impacts on different environmental components and it is found that air quality surrounding crusher units affected more. Impacts on surface water due to dust deposition and waste water influx, contamination of underground water due to deep mining are also very prominent.
