Communities are exposed to pollution through the air, water, and land. Multiple sources of pollution and other environmental stressors can add up over time to cause adverse effects to human health and wellbeing. This is known as “cumulative impacts.” Environmental justice (EJ) communities tend to face greater cumulative impacts, as they are disproportionately exposed to multiple environmental, health, and social stressors. This episode of Groundtruth discusses new regulations in Massachusetts involving cumulative impact analyses for air permit issues in areas near EJ communities. Join Lauren Karam, Beveridge & Diamond's Boston Associate, Stella Keck, a Senior Scientist at Roux, and Andrew Shapero, a Senior Engineer at Roux, to learn more about how states, like Massachusetts, and the EPA are addressing cumulative impacts in EJ communities.
