Oil and gas pipeline safety is a topic of intense interest in the U.S. and around the world.
There are more than 300 known or suspected leaks in the world, most of which have been linked to a single, massive leak.
The BP Deepwater Horizon oil spill, for example, resulted in the loss of a quarter of the country’s marine life.
But the current controversy surrounding the controversial drilling technique known as hydraulic fracturing is also a national concern.
The technology involves pumping water, sand and chemicals at high pressures into underground rock formations, often in order to release natural gas.
In many places around the U, fracking has been banned in order for local water supplies to be used.
In some places, fracking is done at a remote location that is not accessible to the public, and not at the expense of nearby communities.
The technique is widely viewed as environmentally harmful, but in recent years it has become increasingly popular, with more than 3,600 companies participating in fracking operations in the past three years.
Many have been granted permits to begin drilling, and they are also expanding their operations, often with the goal of finding new oil and gas reserves.
The controversy over the use of hydraulic fracturing has also been used to promote other controversial oil and natural gas technologies.
Some states have banned fracking altogether, while others have made it more difficult for new oil wells to be drilled.
The drilling techniques have also been criticized for damaging fragile habitats and polluting water sources, including wetlands.
In 2016, the Obama administration designated the Deepwater Bay Project as a national marine monument, a designation that allows the government to restrict oil and mineral exploration there.
