Dr. Doug Brugge of Tufts University School of Medicine is excited about finally starting a study which he has been preparing for since 2008. On Monday morning at Mt. Vernon Restaurant, he announced data-collection would commence shortly. "Our current goal is to start in early to mid July," he tells a small gathering of concerned residents. "This is the start. We're going to be in Somerville conducting this study for a year. We'll be knocking on doors; we'll have air-monitoring vans driving on the streets," he says. Dr. Brugge has named his study CAFEH, Community Assessment of Freeway Exposure and Health; it has received a $2.5 million grant from the National Institute of Environmental Health Sciences, an arm of the National Institutes of Health. Two other neighborhoods are slated to be identically tested after Somerville: Chinatown in Boston and South Boston, both near major traffic routes.

Mayor Curtatone was present at Monday's kick-off festivities at Mt. Vernon Restaurant. Saying of the study, "I'm here to support the effort…to build awareness to the overall health of the community." And Mayor Curtatone was able to inject some hometown pride, saying that working together is "…going to start undoing the mistakes of the past, and that's really what makes us an All American city."

John Durant, Associate Professor of Civil & Environmental Engineering at Tufts held short, informal tours in of one of the vans that will be driving around East Somerville neighborhoods collecting air quality data. The van it outfitted with computers and gadgets all designed to better interpret and collect pollutants in the air. "Our goal is to cover a swath of Somerville on either side of 93" says Durant. This swath translates to 400 meters on either side of I-93 and intersecting roadways.

The people "knocking on doors" are concerned Somerville residents who volunteered. There are two parts to the "knocking on doors" portion of the study: one, the questionnaire, which asks about diet, exercise, smoking history, and general health. The second part of it, though, is thought to be considerably more important because it involves a blood sample. If those randomly selected do the first part but neglect to do the second part – giving blood – it may invalidate their contribution. "Without the blood we can't really get a clear picture of the study," adds Don Meglio, an administrator at Tufts School of Medicine and the organizer of the kick-off Monday morning at Mt. Vernon. A $20 gift card to a local supermarket is the reward for finishing the questionnaire. More money, in the way of a gift card, will be rewarded for giving a blood sample, informs Dr. Brugge. When asked what he really wishes to gain from this study, Dr. Brugge says, "…that it can be one piece which can affect national policy – that is our goal."
