Deep-Well Injection

A newish CRS report titles Human-Induced Earthquakes from Deep-Well Injection briefly discusses the Army Chemical Corps decision to dispose of its wastes through deep-well injection. The CRS report describes the process, that lead to

an M 4.8 earthquake that struck northeast Denver, on August 9, 1967 was generally accepted as the largest recorded human-induced earthquake in the United States. The M 4.8 earthquake was part of a series of earthquakes that began within several months of the 1961 start of deep-well injection of hazardous chemicals produced at the Rocky Mountain Arsenal defense plant. The earthquakes continued after injection ceased in February 1966.21 The disposal well was drilled through the flat-lying sedimentary rocks into the underlying older crystalline rocks more than 12,000 feet deep, and injection rates varied from 2 million gallons per month to as much as 5.5 million gallons per month.

For additional background, see the original report on deep-well injection (posted below) and of course, that historical treasure, The Blue Book.
