poofmeisterp writes "Due to old cast iron underground pipelines, natural gas leaks run amok in Boston, MA. '"While our study was not intended to assess explosion risks, we came across six locations in Boston where gas concentrations exceeded the threshold above which explosions can occur," Nathan Phillips, associate professor at BU, said in a statement.' With 'a device to measure methane' in a vehicle equipped with GPS, Duke and Boston University researchers created a nice little map showing the methane levels in parts per million at different points in the city. 'Repairing these leaks will improve air quality, increase consumer health and safety, and save money,' study researcher Robert B. Jackson, of Duke, said in a statement. 'We just have to put the right financial incentives into place.' It looks like money is an issue. Imagine that."
