17.6 million Americans live near oil and gas wells and fracking

Those who live within 1 Km from active wells are more at risk of cardiac and neurological problems, cancer and malformation at birth

Physicians, Scientists and Engineers (Why) for Healthy Energy is a non-profit research institute that provides scientific and technical information based on the health, environmental and climatic impacts of energy production and use and is now published on Environmental Perspectives Health  the study "Towards Consistent Methodology to Quantify Populations in Proximity in Oil and Gas Development: A National Spatial Analysis and Review of Environmental and Climate Dimensions of Energy Production and Use," which shows that "approximately 17.6 million Americans live within a kilometer of an active oil or gas well ". The study, conducted with researchers at the California-Berkley University and Havey Mudd Collegs, is the first US census on the number of people living near petroleum and gas production sites, both traditional and fracking wells .

The Why recall that previous studies "have found that active oil and gas production degrades the quality of air, surface water and groundwater; Contaminate soil and increase exposure to noise and light pollution. According to separate studies, when people live within one kilometer of these activities, they have a greater risk of being hospitalized for numerous medical problems, including heart and neurological problems, tumors, and increased incidence and severity of asthma. Neighborhood proximity to these activities has also been associated with birth problems, including premature birth, lower birth weight, neural tube defects, and congenital heart defects.

Yet so far, only a few studies have been published to quantify populations living near petroleum and gas stations and these studies did not link pollutant emissions to certain types of oil and gas production activities.

The study's main author, Eliza Czolowski, explains, "Our study was designed specifically to determine how many Americans saw increased health risks from potential exposure to pollutants emitted by petroleum and gas activities."

In addition to computing the total population of the Usa exposed, researchers analyzed exposure in the various US states by highlighting those with particularly high percentages of population living close to active wells. West Virginia was the most risky state, with 50% of residents living near an active oil or gas well. Right after Oklahoma, it's 47%. La Czolowski. It points out that "When a member on two of a population is potentially exposed to a health risk, this becomes a concern for public health."

Nearly a quarter of Ohioans - 24% - live alongside active wells. MA is the Texas true to most people at risk: 4.5 million. Near live ponds they live 1.4 million children up to 5 years old, a subgroup very vulnerable to environmental exposures

The researchers examined both hydraulic fracturing techniques (fracking) and traditional wells, and Czolowski noted that "Despite the differences in conventional and non-conventional oil production techniques, the health risks can be very similar. Many atmospheric pollutants, including benzene, formaldehyde and particulate matter, are emitted from both conventional and non-conventional activities because they are co-produced with oil and gas, not specifically because a well is fractured hydraulically. Also the emissions of atmospheric pollutants from associated activities, such as drilling wells and truck traffic, are not specific to hydraulic fracturing. "

The researchers point out that some of the data they requested were not available and therefore encourage further studies that follow similarly stringent methodologies, focusing in particular on public health, and taking into ACCOUNT variables excluded from their study, such as population density and activities.

The study concludes that "Given the large number of individuals and the large percentage of populations potentially exposed to pollutants emitted by petroleum and gas activities, protection standards and policies should be considered. Health protection policies may include minimum distances between these activities and places where they live, play and study people, as well as a widespread deployment of the best available technologies to reduce air pollution.
