So close yet so far...
You do realise, as I've mentioned previously, that it's not the same form of fracking that we're discussing previously, right? The difference in technique may be non-existent, as in Wytch farm they pump loads of water into the ground, but it's not laced with chemicals. As Yorkie said, how dare you accuse the 'Green' movement of profiteering on renewable issues, the oil companies have been one of the most evil and destructive byproducts of capitalism in the last 100+ years, causing wars and untold environmental damage whilst taking HUGE subsidies off governments all over the world. Unfortunately our economy is geared towards using as much petrol as possible (as it suits the oil companies quite nicely for us to be dependant on them), but I do everything I can do avoid waste/transport costs/etc...And that point is completely irrelevant anyways, we have other means of obtaining oil/gas that don't involve polluting our countryside and aquifers.
At least w_y supports your nonsense, you can both be wrong together
*sigh*
Do you understand what noxious means? Give it a quick google
Here is the list of chemicals used for hydraulic fracking (the current subject of debate here), sorry it's a cut and paste so w_y will be annoyed, but the source link is there and I don't have your address to post it to you...
ADDITIVE TYPE DESCRIPTION OF PURPOSE EXAMPLES OF CHEMICALS
Proppant “Props” open fractures and allows gas / fluids to flow more freely to the well bore. Sand [Sintered bauxite; zirconium oxide; ceramic beads]
Acid Cleans up perforation intervals of cement and drilling mud prior to fracturing fluid injection, and provides accessible path to formation. Hydrochloric acid (HCl, 3% to 28%) or muriatic acid
Breaker Reduces the viscosity of the fluid in order to release proppant into fractures and enhance the recovery of the fracturing fluid. Peroxydisulfates
Bactericide / Biocide Inhibits growth of organisms that could produce gases (particularly hydrogen sulfide) that could contaminate methane gas. Also prevents the growth of bacteria which can reduce the ability of the fluid to carry proppant into the fractures. Gluteraldehyde;
2-Bromo-2-nitro-1,2-propanediol
Buffer / pH Adjusting Agent Adjusts and controls the pH of the fluid in order to maximize the effectiveness of other additives such as crosslinkers. Sodium or potassium carbonate; acetic acid
Clay Stabilizer / Control Prevents swelling and migration of formation clays which could block pore spaces thereby reducing permeability. Salts (e.g., tetramethyl ammonium chloride) [Potassium chloride]
Corrosion Inhibitor Reduces rust formation on steel tubing, well casings, tools, and tanks (used only in fracturing fluids that contain acid). Methanol; ammonium bisulfate for Oxygen Scavengers
Crosslinker The fluid viscosity is increased using phosphate esters combined with metals. The metals are referred to as crosslinking agents. The increased fracturing fluid viscosity allows the fluid to carry more proppant into the fractures. Potassium hydroxide; borate salts
Friction Reducer Allows fracture fluids to be injected at optimum rates and pressures by minimizing friction. Sodium acrylate-acrylamide copolymer;
polyacrylamide (PAM); petroleum distillates
Gelling Agent Increases fracturing fluid viscosity, allowing the fluid to carry more proppant into the fractures. Guar gum; petroleum distillate
Iron Control Prevents the precipitation of carbonates and sulfates (calcium carbonate, calcium sulfate, barium sulfate) which could plug off the formation. Ammonium chloride; ethylene glycol; polyacrylate
Solvent Additive which is soluble in oil, water & acid-based treatment fluids which is used to control the wettability of contact surfaces or to prevent or break emulsions. Various aromatic hydrocarbons
Surfactant Reduces fracturing fluid surface tension thereby aiding fluid recovery. Methanol; isopropanol; ethoxylated alcohol
Many fracturing fluid chemicals are known to be toxic to humans and wildlife, and several are known to cause cancer. Potentially toxic substances include petroleum distillates such as kerosene and diesel fuel (which contain benzene, ethylbenzene, toluene, xylene, naphthalene and other chemicals); polycyclic aromatic hydrocarbons; methanol; formaldehyde; ethylene glycol; glycol ethers; hydrochloric acid; and sodium hydroxide.
Very small quantities of some fracking chemicals are capable of contaminating millions of gallons of water. According to the Environmental Working Group, petroleum-based products known as petroleum distillates such as kerosene (also known as hydrotreated light distillates, mineral spirits, and a petroleum distillate blends) are likely to contain benzene, a known human carcinogen that is toxic in water at levels greater than five parts per billion (or 0.005 parts per million).
Other chemicals, such as 1,2-Dichloroethane are volatile organic compounds (VOCs). Volatile organic constituents have been shown to be present in fracturing fluid flowback wastes at levels that exceed drinking water standards. For example, testing of flowback samples from Texas have revealed concentrations of 1,2-Dichloroethane at 1,580 ppb, which is more than 316 times EPA’s Maximum Contaminant Level for 1,2-Dichloroethane in drinking water.
VOCs not only pose a health concern while in the water, the volatile nature of the constituents means that they can also easily enter the air. According to researchers at the University of Pittsburgh's Center for Healthy Environments and Communities, organic compounds brought to the surface in the fracturing flowback or produced water often go into open impoundments (frac ponds), where the volatile organic chemicals can offgas into the air.
