News Summary
The Lehigh Valley region of Pennsylvania, specifically Bethlehem, is grappling with significant air quality issues, as highlighted by a recent report from the American Lung Association. Factors such as traffic emissions, especially diesel exhaust and particulate matter, are major contributors to the problem. With a C grade for air quality, the area deals with unique geographical challenges that trap pollutants. Advocacy groups are pushing for solutions like improved public transport and green spaces to combat these environmental concerns, especially for vulnerable populations suffering from asthma.
Pennsylvania is facing significant air quality challenges, particularly in the Lehigh Valley region, which includes Bethlehem. According to the American Lung Association’s “State of the Air” report, Bethlehem and the surrounding area are among the worst in the state for air quality. Primary pollutants in the region include diesel exhaust, nitrogen oxides, and particulate matter originating from traffic and fossil fuel combustion.
The Lehigh Valley’s unique geographical features worsen these air quality issues. The region’s bowl-like structure traps pollutants during temperature inversions, leading to deteriorating air conditions. Currently, the area receives a C grade in air quality, with alarming rankings of 79th for the worst high-ozone days and 24-hour particle pollution out of 223 metropolitan regions across the United States.
While some air quality improvements have been made since the 1980s, these changes have not been uniform throughout the entire Lehigh Valley. South Bethlehem, in particular, faces distinct environmental problems due to its dense urban setting and limited green spaces, which heighten the effects of air pollution. In contrast, neighborhoods with more grass and open areas tend to experience lower pollution impacts, as these spaces allow pollutants to settle into the soil.
In a troubling assessment, the Asthma and Allergy Foundation of America flagged the Lehigh Valley as the most challenging metropolitan region for asthma sufferers in the United States for 2024. The significant presence of diesel emissions, especially from trucks and buses, accounts for about 50% of the air pollution in the state. Such pollution is particularly harmful to individuals with respiratory health issues, including asthma.
The Pennsylvania Department of Environmental Protection (DEP) oversees air quality standards, enforcing regulations through permitting processes to ensure compliance among the numerous facilities in the area. Approximately 500 to 600 facilities in the Lehigh Valley have permits that allow them to emit pollutants, which include cement and other commercial industrial operations.
Despite the ongoing air quality struggles, recent industrial growth, including warehouse expansions in the Lehigh Valley, has resulted in increased truck traffic. This surge in truck activity complicates existing efforts to improve local air quality, as more vehicles on the road lead to higher diesel emissions. Community efforts to enhance air quality have emerged as local advocacy groups push for the establishment of bicycle lanes, improved public transportation, and systemic changes that promote fuel-efficient vehicles.
On a personal level, residents can alleviate some of the adverse effects on high-pollution days by using HEPA filters in their homes. Community-led initiatives complement these individual actions and promote long-term plans aimed at reducing toxicity in the air. Innovative solutions, such as installing electric vehicle charging stations, may also play a crucial role in developing a comprehensive strategy for enhancing air quality in the region.
By taking proactive measures and fostering community involvement, stakeholders hope to address air quality issues while simultaneously managing the challenges posed by increased industrial activity, thereby improving the overall health and well-being of the Lehigh Valley population.
