Testing Surface Mine Blasting Emissions Challenge A rural coalfield community was concerned about possible adverse impacts of mining blast sites on local air quality. Mining blast sites are a significant source of particulate matter (PM) and other potentially hazardous emissions. However, it is difficult to accurately characterize and attribute airborne PM and gaseous emissions once they have been widely dispersed. The community had multiple nearby blast sites dispersed over a large surrounding area, making it difficult to determine the specific impact of the blast sites vs. other sources of emissions. Solution Battelle conducted a special purpose monitoring study to characterize and document air quality while surface mine blasting operations were being conducted nearby. Various sampling
