Study: Fracking chemicals didn’t pollute aquifers

July 20, 2013

PITTSBURGH (AP) — A landmark federal study on hydraulic fracturing, or fracking, shows no evidence that chemicals from the natural gas drilling process moved up to contaminate drinking water aquifer......

nowheretogo-"The trailer park in question would have stayed had it not been sold to the gas/water withdrawl industry."

Actually, the truth is that the mobile home park could no longer add homes to the park. The zoning changed due to it being a flood zone. The park had been for sale for quite some time.

The trailer park was for sale for better then three years. It just so happens that a gas vendor bought it. I believe that the general public has no clue how much trk traffic that place eliminated. We're talking thousands of trips eliminated.

BornHere, yes Kaiser was the gas well; Parson's was the water well. There were 4 old improperly abandoned wells nearby.

"There are four old natural gas wells dating to the 1940s within 1,700 feet of the gas well drilled on Parsons’ property in 1982 – well within range of hydraulic fractures, according to modern industry and government studies.

In its 1987 report, the EPA noted the risk of contamination via old wells, citing Illinois’ investigation of drilling pollution. “To avoid degradation of ground water and surface water, it is vital that abandoned wells be properly plugged,” the EPA noted. “Plugging involves the placement of cement over portions of a wellbore to permanently block or seal formations containing hydrocarbons or high-chloride waters (native brines). Lack of plugging or improper plugging of a well may allow native brines or injected wastes [from a waste fluid disposal well] to migrate to freshwater aquifers or to come to the surface through the wellbore.”

I assume that you are talking about the Kaiser gas well right Texas?

protects the fresh water intervals. This is the general procedure and may vary for deep wells with multiple strings of casing.

The West Virginia well that was the conduit from the fracked well to the fresh water zone was not plugged with this technique.nor do I think the old wells in Tioga Co. that were alleged to allow the same thing on a SWEPI well. Then the well pipe is cut off and capped. In New Mexico a approx 6 ft. pipe with the well name and operator, welded in the pipe, is left standing where the well was. Texas does not require this. Even in New Mexico, on Bureau of Land Management property, they approve the abandonment procedure.

Both service companies and operators are required to file paperwork accurately attesting, at penalty of prison, concerning the abandonment. The states send inspectors the majority of the time to witness the events that they are done properly.

I hope this helps.

Rick424,

State abandonment regulation have to be followed. I don't know what PA's are but in Texas and New Mexico generally they will set a cast iron bridge plug, a special plug that is several feet long and cylindrical in shape almost the full inside diameter of the casing, that presses some "metal teeth" into the casing to hold it static. It also has special elastomer that are expanded and seal off any flow upward or downward. It is set approx 50 to 100 ft above the depleted zone. Then a hundred feet of cement are place on top of the bridge plug, using tubing to accurately place it. Then cement plugs, a hundred feet or more thick, are placed inside the casing every several thousand feet +- up to the to of the point where cement is on the outside of the production casing. Many times they will cut the production casing and remove it from the well. Additional cement plugs are then placed in the hole. They always spot a cement plug across the casing shoe that protec

OMG another steaming pile of lies from the lying liers who are only a mouthpiece for the evil gas industry... The EPA, wait, WHAT?!

Rick:

The same vertical borehole can be re-used to drill a horizontal in another direction. You can get up to 8 horizontal wells from one vertical.

If the well is out of service, it is capped.

Like the millions of water wells and conventional oil/gas wells, they sit. At that point, it is a dry hole, so there is nothing to cause water problems.

Old oil wells are many times re-used as the infrastructure (separators, etc) are already on-site.

so what happens when the well finished its useful life. Is there still a hole in the ground. Are there going to be orphan wells all over the place for future generations to figure out what to do with. Do they fill it up or so they just not care. Steel and concrete only last so long.

CTMopar:

Yes, they drill through the aquifer, but the wellbore is not exposed. It is multiple layers of steel and concrete in the first 800 feet, ensuring the aquifer is separated from the well.

Wells are not just dirt holes.

Folks they drill through the aquifer in some cases and the results may be seen miles down stream(Underground) if the water is still flowing if not the dye just stays put...Aquifers have always cleansed themselves but when you take a 500 million gallon underground lake and reduce it to 10,000 gallons well...

I guess I will have to accept this and move on. Just seems odd that when one of these things comes to the neighborhood someone loses their water. Let us just hope that in the future I am not the one to say I told you so. Get your base line done and if something happens good luck.

Texas is correct. The small explosion are in the perforating process, not in the hydraulic fracturing process.

BornHere is correct. Get your well water tested.

Most people have no clue what is in their water right now.

PS: It's not always pretty.

There is an error in the article. The statement "the fracking process, which involves setting off small explosions to break the rock apart." is not true. There are no explosions to break the rock. The hydraulic pressure the the frac fluid generates causes the rock formations to split apart, much like driving an axe or wedge into a piece of wood.

Bio, before you opine maybe you should do some research first. For one thing we only import 40% of our oil and 100% of the gasoline you burn is manufactured right here in the good old United states. Secondly the trailer court in question was going to disappear whether anyone bought it or not because of zoning.

I've said this for 2 years on here and I'm going to say it again.

The only way you will know what is in your water is to have a "Baseline Water Testing" done BEFORE any drilling happens around your property.

This is all the proof you will need in case something goes wrong with your water.

just like the people that decide its okay to shut down a mobile home park just to build a water removal thing for the gas industry, resulting in so many people, including people with limited resources, losing their homes. homes they could afford to own. just like no matter how much we the people fight to keep it off of state game lands, MONEY LINING THE POCKETS of decision makers,, makes the final decision. HOGWASH.. any CHEMICAL that goes into the water anywhere, eventually gets into the drinking water basin.. RAIN water has chemicals in it, it falls into the resevoir.. its all hogwash. i dont believe it for a minute. and STICK IT UP YOUR hind parts those that want to say OH thats what powers your cars. NO, it doesnt. gas and oil from foriegn countries do. not that i agree with that, but thats wehre it comes from NOT underground here in central pa

I read this on Huffington post and one of the commenters said it's all lies and that thousands of people in northwest PA have natural gas in all their organs.

We can blame that on fracking or as in my case it would be blamed on that potato salad I had last night.

Whew........
