Intra-abdominal pain is also known as stomach pain, stomachache, bellyache and abdominal cramps. Abdominal pain can be from abdominal wall or intra-abdominal organs. Intra-abdominal pain is not an abdominal wall pain. The abdomen is the section of body between chest and pelvis. Intensity of intra-abdominal pain is mild to severe and duration can be short (acute) or long (chronic). Some intra-abdominal pain may be present for days, weeks or months.
The average well is up to 8,000 feet deep. The depth of drinking water aquifers is about 1,000 feet. The problems typically stem from poor cement well casings that leak natural gas as well as fracking fluid into water wells.
Fracking, or hydraulic fracturing, is a controversial process for extracting oil and natural gas from the ground It's spreading across the US despite there being a lot of concerns about it. A typical oil well is built straight down and pumps out all of the oil and natural gas that is deep down in the earth. But after continual use, these oil wells can start coming up dry. So fracking involves angling the drill horizontally into the rock layer and then blasting water at high pressures (this is why its called hydraulic) to release natural gas.
