who drills salt water disposal wells

To expel brine and other residuals obtained during the process of oil and gas extraction, the industry depends on salt water disposal wells. These facilities are dug to an average depth of 8,000 feet and encased with a cement seal to ward off any contamination of underground aquifers.

Produced as a result of extracting oil and gas, brine is an incredibly salty solution that holds the potential to taint drinking water with various chemicals such as benzene, toluene, and xylene if it seeps into the ground.

The US oil and gas industry relies heavily on salt water disposal wells as an efficient means of disposing of brine; over 150,000 of such wells are currently in operation.

The process of drilling for salt water disposal wells involves a rotary drilling rig, a drill bit, and a pipe. The drill bit is responsible for establishing a cavernous opening in the earth while the long-stemmed pipe is inserted into the aperture to contain the brine which is then injected into it at force.

Deep below the water table, a brine solution is precisely injected into a well so that it is securely stored within layers of porous rock. Increased pressure from the brine ensures that the pores remain open in the rock formations, thus ensuring that the brine does not seep and contaminate any nearby groundwater.

In order to protect our groundwater, the U.S. Environmental Protection Agency has implemented regulations that mandate salt water disposal wells must be designed and utilized in a manner that prevents tainting of the water source.

Before salt water disposal wells may be operated, the Environmental Protection Agency (EPA) demands that a license be obtained. Furthermore, a strategy must also be provided to the EPA which details how contamination of groundwater will be effectively prevented.

Each salt water disposal wells must periodically be monitored by its operator, who must then present a report detailing the results to the EPA.

Ensuring that groundwater remains safe from pollutants is key, and salt water disposal wells act as a reliable means of accomplishing that goal for the oil and gas industry.
