In May 2000 we invited representatives from New Hampshire's Department of Environmental Services and New Hampshire's Department of Health and Human Services along with representatives from the U.S. Geological Survey to a meeting in Concord, New Hampshire. The purpose was to draw attention to our overlapping interests and activities around the presence of arsenic in the state and its consequence for public health, particularly through drinking water contamination. In May 2001, the Environmental Protection Agency, Region I Office also accepted an invitation to join the Consortium. The NH Arsenic Consortium has become a truly collaborative group, with goals and projects determined by its partners. The mission of the Consortium is to exchange information, facilitate coordination of research and public outreach and to foster future research collaborations. The Consortium sponsored an interdisciplinary scientific conference on arsenic in May, 2002. More than 175 people from all over the United States attended.
