Exposure to Air Pollutants from Marcellus Area Gas Exploration and Production is Improving Post-2014/2021 Peak

In a poster our team is presenting today at the Health Effects Institue Annual Conference, our preliminary research shows that the air emissions intensity of Marcellus area gas wells is decreasing with peak exposures occurring between 2014 and 2021 depending on the pollutant. While technology has been improving to reduce emissions and leakage, lateral wells have been growing longer counteracting some of this benefit. In other regions of the US this is not necessarily true unless they are also installing equipment to capture natural gas.
