Document Summary
Forms of hydrocarbons: crude oil (liquid, natural gas (gas, coal (solid) A hydraulic fracture is formed by pumping the fracturing fluid into the wellbore at a pressure that exceeds the strength of the rock. The rock cracks and the fracture fluid continues further into the rock, extending the crack still further, and so on. Natural gas flows into the pipe and is collected. Fracking allows toxic chemicals and methane gas seeps into the drinking water. Experts fear that unacceptable levels of radioactive radium 226 in gas development waste. Fracking chemicals are linked to bone, liver, and breast cancers, gastrointestinal, circulatory, respiratory, developmental as well as brain and nervous system disorders. Such chemicals are present in frack waste and may find their way into drinking water and air. Marcellus formation: marine sedimentary rock found in eastern n. america, named for a distinctive outcrop near the village of marcellus, ny in the us.
