Eastern Shore Ammonia Air Monitoring Project

The Environmental Integrity Project and Assateague Coastal Trust monitored gaseous ammonia levels at residential properties near large poultry operations in Somerset and Worcester Counties using passive samplers. Samples measured two-week average concentrations from June 2020 through June 2022 within 72-122 meters (236-400 feet) of active, large poultry operations, with a density of 36 chicken houses (and 1.26 million chickens) within a one-mile radius. This white paper summarizes methods, findings, and recommendations based on the outcome of the community monitoring project.
