Potential Public Health Hazards, Exposures and Health Effects from Unconventional Natural Gas Development

03/04/2014

Potential Public Health Hazards, Exposures and Health Effects from Unconventional Natural Gas Development, authored by John L. Adgate,*,† Bernard D. Goldstein,‡ and Lisa M. McKenzie†, provides a detailed review of the range of potential risks to public health and evaluates the state of the evidence. Up to date, extensive overview.

ABSTRACT: The rapid increase in unconventional natural gas (UNG) development in the United States during the past decade has brought wells and related infrastructure closer to population centers. This review evaluates risks to public health from chemical and nonchemical stressors associated with UNG, describes likely exposure pathways and potential health effects, and identifies major uncertainties to address with future research.

Study Finds High Levels of Arsenic in Groundwater Near Fracking Sites

01/31/2014

A recently published study by researchers at the University of Texas at Arlington found elevated levels of arsenic and other heavy metals in groundwater near natural gas fracking sites in Texas’ Barnett Shale.

While the findings are far from conclusive, the study provides further evidence tying fracking to arsenic contamination. An internal Environmental Protection Agency PowerPoint presentation recently obtained by the Los Angeles Times warned that wells near Dimock, Pa., showed elevated levels of arsenic in the groundwater. The EPA also found arsenic in groundwater near fracking sites in Pavillion, Wyo., in 2009 — a study the agency later abandoned.

ProPublica talked with Brian Fontenot, the paper’s lead author, about how his team carried out the study and why it matters.

Canadian National Farmers Union warns against fracking

01/31/2014

Alberta farmers who live near fracking installations lose the peace, quiet and beauty of their countryside. There is more noise, dust, light pollution, air pollution, traffic on and damage to country roads, damage to fields, loss of productive acres, interference with wildlife habitat, loss of recreation opportunities, potential water shortages, chemical spills on farmland and into surface waters, and reduction in property values. It is more time-consuming and costly to work land that is criss-crossed by fracking infrastructure. Emissions from wells and equipment may be hazardous to the health of people and animals. There is ever-present worry about the danger of irreversible contamination of groundwater and the resulting loss of wells for watering livestock, irrigating crops and domestic consumption.

Perhaps even more offensive than the tangible burdens that fracking imposes on farmers, are the attempts to silence and intimidate concerned rural citizens. The ERCB has a history of limiting access to its hearings by defining “affected party” very narrowly, thus denying voice to many who have legitimate concerns.

The NFU submission to the ERCB is framed by our call that its new regulatory approach be guided by the Precautionary Principle, “Where there are threats of serious or irreversible damage, lack of full scientific certainty shall not be used as a reason for postponing cost-effective measures to prevent environmental degradation,” as Canada agreed to in the 1992 Rio Declaration.

Groups Urge Probe of EPA Actions in Texas Water Contamination Case

07/11/2013

A decision to drop legal action against a drilling company despite evidence that it polluted residents’ well water in Texas prompts outcry by more than 80 US organizations.
More than 80 organizations from 12 states and a New York state senator today called on the inspector general of the U.S. Environmental Protection Agency to investigate a decision to drop legal action against a drilling company despite evidence that it had polluted residents’ well water near Fort Worth, Texas.
The organizations sent a letter to EPA Inspector General Arthur A. Elkins, Jr., asking him to broaden an ongoing investigation of a case that made national news last year when the EPA dropped an enforcement action against Range Resources Ltd. after earlier invoking rare emergency authority under the Safe Drinking Water Act. New York State Senator Tony Avella is sending a similar letter later today. Elkins began investigating the case after six U.S. senators asked him last June to determine whether EPA had followed proper procedures.

Gas industry must make changes to protect health

05/30/2013

It will take years for the full health impact of natural gas development to be known. Authors of a new peer-reviewed study urge that steps be taken now to protect the health of humans and the planet. Modern Natural Gas Development and Harm to Health: The Need for Proactive Public Health Policies argues that the natural gas industry must make changes now to protect the health of people and animals.
The paper provides a literature review of unconventional natural gas development and its effects on human health. It focuses on impacts on children’s health, general harm to health, water contamination and air and soil contamination.

Hydraulic Fracking a Danger to Water, Food, Farmland: NFU Calls For Moratorium

01/31/2013

(Rimbey, Alberta, February 23, 2012)  “Many farmers in my area who either have direct experience with the destructive nature of hydro-fracking technology on their water wells, or who have neighbours who have been affected have come to me with their concerns” says Jan Slomp, Rimbey area dairy farmer and Region 7 (Alberta) Coordinator for the National Farmers Union (NFU). “We are in the heart of Alberta’s oil and gas country where our ability to produce good, wholesome food is at risk of being compromised by the widespread, virtually unregulated use of this dangerous process.” At NFU Region 7’s recent public meeting dozens of concerned farm families heard how their neighbours, the Campbell family from Crestomere, Alberta, had their water well contaminated by highly toxic compounds, which they clearly linked to the fracking of a nearby oil and gas well.  Several other attendees then brought forward their stories of losing water wells to fracking near their own farms.  “Not many of these stories get made public because the oil and gas companies usually force farmers to sign confidentiality agreements in return for replacement of their water wells” said Slomp. Iain Aitken, an Alberta cattle rancher and local NFU member observed, “Farmers […]

EPA Links Water Contamination to Fracking in Pavillion, Wyoming

07/13/2012

In a first, federal environment officials today (Dec. 8, 2011) scientifically linked underground water pollution with hydraulic fracturing, concluding that contaminants found in central Wyoming were likely caused by the gas drilling process. …
Beginning in 2008, the EPA took water samples from resident’s drinking water wells,finding hydrocarbons and traces of contaminants that seemed like they could be related to fracking. In 2010, another round of sampling confirmed the contamination, and the EPA, along with federal health officials, cautioned residents not to drink their water and to ventilate their homes when they bathed because the methane in the water could cause an explosion.

To confirm their findings, EPA investigators drilled two water monitoring wells to 1,000 feet. The agency released data from these test wells in November that confirmed high levels of carcinogenic chemicals such as benzene, and a chemical compound called 2 Butoxyethanol, which is known to be used in fracking.

The findings by the Environmental Protection Agency come partway through a separate national study by the agency to determine whether fracking presents a risk to water resources.

In the 121-page draft report released today, EPA officials said that the contamination near the town of Pavillion, Wyo., had most likely seeped up from gas wells and contained at least 10 compounds known to be used in frack fluids.
