About EHP

The Environmental Health Project (EHP) is a nonprofit public health organization that assists and supports residents of Southwestern Pennsylvania and beyond who believe their health has been, or could be, impacted by unconventional oil and gas development (UOGD, or “fracking”).

EHP’s team includes medical professionals, community service professionals, and public health scientists who are available to assist individuals and communities in many ways:

  • EHP’s onsite Nurse Practitioner is available for exams and consultations with people who think their health may be compromised by nearby UOGD activities. Clients can be seen by appointment in our local office or in their homes. Our Nurse Practitioner also provides referrals, helps clients navigate the health care system, and consults with environmental health specialists.
  • EHP is also a resource center for information related to UOGD activities. Our staff is available by appointment in the office and by phone to address concerns residents have about their environmental conditions. We will answer questions, provide guidance, and steer people toward other resources when possible. EHP also provides limited air and water quality monitoring devices to qualified residents. 

At EHP we are aware that the lack of objective, reliable data on the health effects of UOGD activities raises many questions about the origins of residents’ health problems and the scope of public health risks in communities. We do not, however, see this uncertainty as a cause for inaction. As public health professionals we know that the perception in the community of environmental dangers, along with plausible sources of hazardous substances, are reason enough to provide a public health response.

While governmental agencies and other institutions are beginning the extensive research required to help determine adverse health and environmental impacts on regions affected by UOGD, this type of research takes a long time to conduct. We know people need information and help now!
