Health Issues

Do you think your health may be affected by nearby unconventional oil and gas development (UOGD or “fracking”)? If you have any concerns about your environmental conditions, be sure to let your health care provider know or contact EHP for help.

EHP’s Family Nurse Practitioner serves the needs of both adults and children whose health may be affected by UOGD (“fracking”). She is available by appointment for both home and office visits and makes referrals to appropriate health specialists on an as needed basis.

The EHP office, located in Washington County, PA, is open Monday – Friday 8:30 a.m. to 4:30 p.m. by appointment only. To discuss your health concerns and schedule a visit, please contact EHP at 724-260-5504 or info [at]

Historically, rich natural resources of timber, rocks, and minerals in Pennsylvania (and other states) helped to industrialize the nation through the production of iron, steel, coal, and oil. Each of these industries had a direct and visible impact on our environment. Environmental abuses were met with changes in law and policy to restore balance to the use of resources and protect the environment and public health.

Today, according to the Pennsylvania Department of Health (DOH), environmental health examines how different environments affect a person’s well being. For example, the health effects of breathing air or drinking water are researched in specific locations where there may be cause for concern. DOH environmental health staff members work closely with federal, state, county, and local officials, as well as with the public, to help address environmental health issues and concerns.


Data suggest that unconventional oil and gas development (UOGD or “fracking”) poses substantial risk to public health from the toxic chemicals used during the industrial process, as well as from other associated problems. It is believed that the potential consequences of “fracking” begin at the onset of drilling and may last long after the operation has ended.

Research is mounting on the emissions from UOGD at all stages and on health effects experienced by nearby residents. Many of the toxic chemicals that have been found in air and water samples around UOGD operations have well known adverse health effects. For example, benzene is a known carcinogen (cancer-causing), toluene is a neurotoxin, and hydrogen sulfide irritates the lungs and can cause asthma. Noise and light pollution is associated with hearing loss, sleeplessness, and other health issues. Prolonged stress can also lead to significant health problems like heart disease, cancer, and depression.


Toxic pollutants can enter our bodies through inhalation, ingestion, and absorption. Environmental pollutants can affect anyone, but some people like children, pregnant women, older adults with preexisting health conditions, and industry workers may be at greater risk. If you live near UOGD operations, you may be exposed in the following ways:

  • Breathing polluted air
  • Drinking, cooking with, and bathing with contaminated water
  • Eating food grown in contaminated soil

Individuals may also experience harmful levels of stress and health problems from the noise, vibration, and light pollution associated with heavy industrial activities.


One frequently asked question is whether individuals living or working near UOGD sites such as well pads, compressor stations, or production facilities should undergo blood or urine testing (called biomonitoring) to determine if they have harmful chemicals in their body as a result of exposures from these operations. While biomonitoring tests may be appropriate in a few cases, EHP does not routinely recommend them because of their limitations.

Results of biomonitoring testing in the UOGD setting are often misleading for several reasons:

  • Most of the chemicals associated with UOGD activity are cleared rapidly from the body, so a test may not show the presence of a chemical even if you were exposed to a pollutant. This may result in a “false negative” result.
  • Many chemicals have multiple sources of exposure in the environment. Because of this, it can be difficult to determine if a positive result is from a UOGD-related exposure or from some other exposure. This may result in a “false positive” result.
  • Some toxic exposures may not have an associated, measurable substance in the blood or urine that is specific to the chemical of concern. In this scenario, even if an exposure to environmental pollutants did occur, there may be no information available to interpret whether or not the exposure poses a health risk to the individual.
