The AP found that Pennsylvania received 398 complaints in 2013 alleging that oil or natural gas drilling polluted or otherwise affected private water wells, compared with 499 in 2012. The Pennsylvania complaints can include allegations of short-term diminished water flow, as well as pollution from stray gas or other substances. More than 100 cases of pollution were confirmed over the past five years.
Extracting fuel from shale formations requires pumping hundreds of thousands of gallons of water, sand and chemicals into the ground to break apart rock and free the gas. Some of that water, along with large quantities of existing underground water, returns to the surface, and it can contain high levels of salt, drilling chemicals, heavy metals and naturally occurring low-level radiation.
But some conventional oil and gas wells are still drilled, so the complaints about water contamination can come from them, too. Experts say the most common type of pollution involves methane, not chemicals from the drilling process.

Ya see!!! Its not caused by climate change (as many of us keep saying), its the fracking!

You know, if they are going to start fracking near your house, it would be good to get your water tested before hand so that if something happens, you have evidence to prove it was good water. Also keeping a sample and having witnesses to show you got it from your well would be a good idea, having a seal put on the container that is initialed.
But remember, if you sue, the well drilling company may hire your witness or their kid and they may say they were not sure that it was the sample.
Prior to the drilling, the methane levels detected in the Klines' tap water -- which comes from a well -- were 9 milligrams per liter (mg/L), which is considered safe. Now, the levels have spiked to 22 mg/L.
Debby Kline told the station that lighting a candle near the running faucet set off "a huge explosion -- the entire sink up to the ceiling."
The Portage County woman said she had previously noticed the water "fizzing."
Dangerously high levels of methane -- a highly flammable gas -- in the water appear to be the culprit. A natural gas company began drilling near the home six months ago, NBC 4 reported, and the Klines suspect the company may be responsible for their flammable water.
The Klines said that because purchasing a methane filter would cost around $8,000. For now, they're drinking bottled water, but they're still bathing in the water straight of the tap.
"We don't know the consequences of sitting in gas water," Debby told TODAY. "We just don't have a choice."
Methane in drinking water is not "usually" considered a health threat, according to the Water Systems Council. The real danger occurs when the gas escapes from the water and builds up in the air, especially in "poorly ventilated or confined areas."
The Council's fact sheet states that in addition to presenting explosion hazards, methane in the air "acts as an asphyxiate," which means it can "displace air and can cause breathing and other health problems."

I highly doubt if those people will see a cent for many years from the gas company. They will drag it out in court for many years and look for any excuse other than their actions to pin it on. Lawyers know they will eventually have to pay but they do not make it easy to collect. This will dissuade most people from suing. Later on the drilling company will go bankrupt and be protected, because they followed all the regulations that the government set.
Dragging things out for years is a common legal practice then they offer a settlement and the people are not allowed to comment. The lawyer the people get tells them to be quiet too, not telling others what goes on. It is a scam in the legal system.
It took nearly 250 years for the levels to triple from around 250 ppb to over 700 ppb. Then it suddenly leveled off for a decade. Then, in 2007, it skyrocketed. In what took 250 years took only 7 years this time around…methane levels tripled again. Now, the levels are over 2,000 ppb.
Why did this happen? That is the greatest mystery in the history of mankind.
The Context
Because methane is mostly well-mixed in the atmosphere, emissions from the Arctic or from the US must be seen within the context of the global sources of methane to the atmosphere. Estimates of methane emissions from the Arctic have risen, from land (Walter et al 2006) as well now as from the continental shelf off Siberia.
Call it 20-30 Tg CH4 per year from both sources. The US is apparently emitting more than we thought we were, maybe 30 Tg CH4 per year. But these fluxes are relatively small compared to the global emission rate of about 600 Tg CH4 per year. The Arctic and US anthropogenic are each about 5% of the total.
Changes in the atmospheric concentration scale more-or-less with changes in the chronic emission flux, so unless these sources suddenly increase by an order of magnitude or more, they won’t dominate the atmospheric concentration of methane, or its climate impact.
Is this bad news for global warming?
Not really, because the one real hard fact that we know about atmospheric methane is that it’s concentration isn’t rising very quickly. Methane is a short-lived gas in the atmosphere, so to make it rise, the emission flux has to continually increase.
This is in contrast to CO2, which accumulates in the atmosphere/ocean system, meaning that steady (non-rising) emissions still lead to a rising atmospheric concentration. There is enough uncertainty in the methane budget that tweaks of a few percent here and there don’t upset the apple cart.
Since the methane concentration wasn't rising all that much, its sources, uncertain as they are, have been mostly balanced by sinks, also uncertain. If anything, the paper is good news for people concerned about global warming, because it gives us something to fix.

Yeah, but it's the fracking that's causing the climate change...well, the boost that we've seen over the past 7 years.
Gas flaring releases of large amounts of methane, which has a high global warming potential. The methane is accompanied by the other major greenhouse gas, carbon dioxide, of which Nigeria was estimated to have emitted more than 34.38 million metric tons of in 2002, accounting for about 50% of all industrial emissions in the country and 30% of the total CO2 emissions. While flaring in the west has been minimized, in Nigeria it has grown proportionally with oil production.[26]
Nigeria flares more natural gas associated with oil extraction than any other country, with estimates suggesting that of the 3.5 billion cubic feet (100,000,000 m³) of associated gas (AG) produced annually, 2.5 billion cubic feet (70,000,000 m³), or about 70% is wasted via flaring.[citation needed] This equals about 25% of the UK's total natural gas consumption, and is the equivalent to 40% of the entire African continent's gas consumption in 2001.
"Nigeria currently flares 75% of the gas it produces.".[26]
Nigeria is to penalise oil giants for flaring gas but campaigners say it's unlikely to curb the release of greenhouse gases in the country, which is the world's second biggest offender after Russia.
Toxic orange flares – a byproduct of Nigeria's 2m-barrel-a-day oil industry – spew the equivalent emissions of the UK's annual gas use every three months in the palm-fringed Niger Delta. Nigeria has Africa's largest natural gas reserves, which could be used for power generation if trapped.
"Because of the flares it is so hot, it is smoky, the air is thick and it is constantly daytime here," said Aniete Aniete, a fisherman from the oil-producing Delta heartland. "Our rivers are black and the [acid] rain eats our houses. Our bodies are covered in oil. You feel that if you live to old age here, it is a miracle."
