Comprehending Health Implications of Natural Gas Development Through Public Health Research
Predicted Regional Ozone Impacts in TX and LA Kembal-Cook, 2010 Enviro Sci Technology
• Ozone Impacts of Natural Gas Development in the Haynesville Shale– Increases of 5 ppb
from increased precursors 2 to NG
FIGURE 4. Twelve km grid ozone modeling results: a) Episode average difference in daily maximum 8-h ozone (ppb): HaynesvilleLow Secenario-2012 Baseline and b) Episode average difference in daily maximum 8-h ozone (ppb): Haynesville High Scenario-2012Baseline and c) Episode maximum difference in daily maximum 8-h ozone (ppb): Haynesville Low Scenario-2012 Baseline and d)Episode maximum difference in daily maximum 8-h ozone (ppb): Haynesville High Scenario-2012 Baseline.
Global Climate Change & NG Lifecycle Topic of much debate and uncertainty
Lifecycle GHG EmissionsBased on emission estimates• Howarth, 2011 Climatic Change
– Shale gas > conventional gas> coal• Weber, 2012 Environ Sci Technol
– Shale gas = conventional gas < coal• Burnham 2012 Environ. Sci Technol
– Shale gas = conventional gas < coal• Alvarez, 2012 PNAS
– NG < coal (electricity generation); – NG > gasoline, diesel (transportation)
• Due to inefficient engines and leaky distribution system
Lu, 2012 Environ. Sci. Technol.
CO2 emissions from power plants decreased in 2009 relative to 2008, due to cheaper NG
Methane Leaks

Nathan Phillips, Picarro
Measurements of GHG in Atmosphere Greater than Estimates• Katzenstein, et al 2003
• Methane and other hydrocarbon emissions from oil and gas fields underestimated
• Petron, 2012 J Geophysical Atmospheres• Methane from Natural Gas activities in
Colorado likely underestimated by a factor of 2
Planned Research
• University of Colorado – Air and water quality, social science, human health, information
technology, outreach and education
• Colorado State University– Assess air emissions and dispersion of drilling, hydraulic fracturing,
flowback in Garfield County, CO– Data released in 2015
• Geisinger Health System– Pennsylvania integrated health care delivery system– Longitudinal dataset of health outcomes for researchers to determine NG
related health outcomes– Health, environmental, community, occupational data
