Boston riddled with mostly small natural gas leaks, Boston University study finds
By Beth Daley
Globe Staff / November 19, 2012
Natural gas is escaping from more than 3,300 leaks in Boston’s underground pipelines, according to a new Boston University study that underscores the explosion risk and environmental damage from aging infrastructure under city sidewalks and streets
The vast majority of the leaks are tiny, although six locations had gas levels higher than the threshold at which explosions could occur. Although there have been no reports of explosions in Boston from any of the leaks, the study comes three years after a Gloucester house exploded probably because of a cracked and corroded gas main dating to 1911.
The research, being published Tuesday in the journal Environmental Pollution, confirms what Bostonians sometimes smell on city streets: a telltale whiff of gas.
“It is something that is distributed across all neighborhoods in Boston,’’ said Nathan Phillips, associate professor in BU’s Department of Earth and Environment and a lead author of the study. Phillips and an assistant drove a black hatchback over every one of Boston’s 785 miles of roads to test methane, the primary ingredient in natural gas, in the air. “And we know once we go outside of Boston, Newton is just as leaky. . . . Any old, mature city is going to have this problem.” Continue reading the entire globe article…
“RCN-SEES: Engineering Research Collaboratory for Sustainable Infrastructure in a Changing Climate” The goal of this 4-yr grant is to create a multi-institution collaboratory to support the integration of climate science and engineering research for sustainable transportation infrastructure (Infrastructure and Climate Network – ICNet). Prof. Anderson serves as a Co-I on this proposal and will provide expertise on the changing nature of climate extremes and the risk they pose to the physical transportation infrastructure around New England.

Salt marshes are highly productive coastal wetlands that provide important ecosystem services such as storm protection for coastal cities, nutrient removal and carbon sequestration. Despite protective measures, however, worldwide losses of these ecosystems have accelerated in recent decades1. Here we present data from a nine-year whole-ecosystem nutrient-enrichment experiment. Our study demonstrates that nutrient enrichment, a global problem for coastal ecosystems2, 3, 4, can be a driver of salt marsh loss. We show that nutrient levels commonly associated with coastal eutrophication increased above-ground leaf biomass, decreased the dense, below-ground biomass of bank-stabilizing roots, and increased microbial decomposition of organic matter. Alterations in these key ecosystem properties reduced geomorphic stability, resulting in creek-bank collapse with significant areas of creek-bank marsh converted to unvegetated mud. This pattern of marsh loss parallels observations for anthropogenically nutrient-enriched marshes worldwide, with creek-edge and bay-edge marsh evolving into mudflats and wider creeks5, 6, 7. Our work suggests that current nutrient loading rates to many coastal ecosystems have overwhelmed the capacity of marshes to remove nitrogen without deleterious effects. Projected increases in nitrogen flux to the coast, related to increased fertilizer use required to feed an expanding human population, may rapidly result in a coastal landscape with less marsh, which would reduce the capacity of coastal regions to provide important ecological and economic services.

Faculty in E&E, in conjunction with faculty in the School of Management and the College of Engineering, have launched a new Minor in Sustainable Energy that is available to any student in a four-year undergraduate School or College. The Minor includes the essential elements of energy from the business, economics, policy, and engineering perspectives, as taught by faculty in those areas…Read more…
To explore ways of maximizing the benefits of natural gas development while minimizing potential negative effects on human communities and ecosystems, the National Science Foundation (NSF) has entered into a cooperative agreement with a University of Colorado Boulder (CU-Boulder)-led team of scientists, engineers and educators and eight partner organizations.
NSF has also entered into a cooperative agreement with another interdisciplinary team of scientists, engineers and educators; it supports a multi-institution research network on sustainable climate risk management strategies. The network is centered at Penn State University and involves nine other U.S. universities and research institutes.
Known as NSF Sustainability Research Networks, or SRNs, the teams will focus on the effects of natural gas development on air and water resources, and on how to adapt to and mitigate the risks of climate change, while developing new sustainability strategies in an altered world. Read more…
Dr. Gina Sapiro, Dean of the College of Arts & Sciences, has named Professor Curtis Woodcock the inaugural chair of the Department of Earth & Environment. Professor Woodcock’s research interests include the use of remote sensing to study forest change and its impact on terrestrial carbon budgets. He previously served as chair of the Department of Geography & Environment.
Student advising for the new department is now located in CAS Room 131. The main department office is now in CAS Room 130.
