BU researchers identify extensive methane leaks under streets of Boston
Date:5/13/2011

Earlier this year, Boston University researchers and collaborators conducted a mobile greenhouse gas audit in Boston and found hundreds of natural gas leaks under the streets and sidewalks of Greater Boston. Nathan Phillips, associate professor of geography and environment and director of BU's Center for Environmental and Energy Studies (CEES), and his research partners will present these and related findings at NOAA's Earth System Research Laboratory (ESRL) Global Monitoring Annual Conference, May 17-18 in Boulder, Colorado.

Phillips and partners Picarro, Inc., Gas Safety USA, and the Cooperative Institute for Research in Environmental Sciences, University of Colorado, Boulder are currently researching the economic and environmental impacts of these leaks. Their work updates earlier findings that unaccounted-for gas amounted to eight billion cubic feet in Massachusetts, costing about $40 million. Such gas leaks have been implicated in damage and mortality of urban and suburban street trees. Evidence from other cities indicates that the situation in Boston is likely similar to cities and towns across the nation.

In an attempt to identify major methane sources in Boston and Indianapolis, Phillips and his research partners systematically measured methane (CH4) concentrations at street level using a vehicle-mounted cavity "ringdown" analyzer. A number of discrete sources were detected at concentration levels in excess of 15 times background levels. Background levels of methane were also measured to be 10 percent higher than the world-wide average of 1.860 ppm. Measurements of CH4 concentration levels along with detailed location information will be presented. In addition, chamber flux measurements of discrete sources will also be presented.

Recent measurements indicate that urban emissions are a significant source of CH4 and in fact may be substantially higher than current inventory estimates. As such, urban emissions could contribute 7
