DEEP WELL INJECTION |

Companies
that generate aqueous wastes such as acids and brines may
find conventional liquid waste treatments expensive and
environmentally risky. For these companies, deepwell injection
can be an attractive alternative. Involving the pumping
of liquid wastes under pressure into porous rock formations
deep underground, deepwell injection is usually less expensive
and more environmentally sound than any other liquid waste
treatment method.
ENVIRONMENTALLY SOUND DISPOSAL
Near Vickery, Ohio, the geologic setting is perfect for deepwell injection. Almost
three thousand feet below rolling farmland lies the Mt. Simon Formation, a layer
of porous sandstone stretching over thousands of square miles. Because the Mt.
Simon Formation is sandwiched between layers of impenetrable rock above and
below, wastes are contained and held indefinitely without posing any risks to
people, animals, plants, groundwater supplies or drinking water resources.
Since the late 1970s, Vickery Environmental Inc., a Waste Management company, has been using this natural depository by pumping liquid wastes under pressure into its subterranean confines. Today the Vickery facility accepts liquid wastes from generators across North America, providing them with a safe, economical and permanent disposal alternative.
WASTES ACCEPTED
Vickery accepts a wide variety of hazardous and non-hazardous
aqueous wastes from industrial operations, including
wastes that are subject to Land Disposal Restrictions.
Acceptable wastes include:
Airport de-icing fluids Ammonia and other caustic wastewaters Aqueous solutions of pesticides and pharmaceuticals Brines and salt solutions Chemical manufacturing wastewaters Leachate Metal plating and galvanizing solutions Waste pickle liquor (acids)
The facility does not accept radioactive waste, medical waste, aqueous waste with a flashpoint less than 212 degrees F, TSCA waste (i.e., PCBs) and F-listed dioxin waste.
STATE-OF-THE-ART TECHNOLOGY
Vickery utilizes the latest in liquid storage, pumping
and monitoring technology to ensure the long-term integrity
of its system.
Liquid wastes received from customers are first stored in aboveground tanks with approximately one million gallons of permitted capacity. After analysis, treatment and filtering, the wastes are transferred through an aboveground piping system to one of four fully permitted Class 1 injection wells.
Each well is composed of fiberglass tubing surrounded by four to six encasement layers of steel and concrete. Between the innermost layer of protective steel and the injection tubing is a space called the annulus, which is filled with fluid maintained at a pressure that is higher than the pressure inside the injection tubing. This pressure differential ensures that in the event of a breach in the injection tube, no wastewater can escape into the surrounding environment.
Advanced computer systems with built-in redundancies continuously monitor and control the wells and verify that they operate in full compliance with all permit requirements. In addition to these automatic safeguards, trained employees routinely make visual inspections of the equipment, and annual testing is done to confirm the wells' mechanical integrity.
