Concerned Health Professionals of Maryland is a project of Chesapeake Physicians for Social Responsibility (Chesapeake PSR), with the support of the Alliance of Nurses for Healthy Environments and the Maryland Environmental Health Network and other health professionals concerned about the impacts of fracking.

Our Work

Concerned Health Professionals of Maryland seeks to amplify the voices of clinicians, researchers, and other health professionals who are concerned about the potential health effects of unconventional natural gas development and production (“fracking”) in Maryland.  Studies are now emerging that suggest there are significant adverse health consequences from exposures related to fracking; however, the full nature and extent of the risks to public health will require decades to clarify.  Given that there is no credible evidence that a regulatory approach can adequately protect public health and the environment, we oppose any efforts to allow fracking to begin in our state at this time.

Concerned Health Professionals of Maryland provides an online resource for the public, media, policy makers, and other health professionals to learn of the latest research on the health and environmental impacts of fracking and fracking-related activities and infrastructure.  We work to engage health professionals across the state in efforts to educate the public and policymakers on these impacts.  As part of this effort, speakers are available to make educational presentations to community groups, legislators, and others who have an interest in protecting communities.

I have considered all of the data and find significant questions and risks to public health, which as of yet are unanswered. I think it would be reckless to proceed in New York until more authoritative research is done. I asked myself, ‘Would I let my family live in a community with fracking?’ The answer is ‘no.’ I therefore cannot recommend anyone else’s family to live in such a community either.
