Spartan Drilling Well Decommissioning and Sealing Procedure Summary
Well decommissioning procedures effectively seal the well casing and boreholes. By doing this it prevents water from mixing between discrete aquifer zones. Another reason is to avoid intrusion of surface water, liquids or other contaminants. Spartan Drilling simple step-by-step is as follows:
Removal of Well Equipment: All obstructions need to be removed from the well, including; well pump, piping, equipment, etc.
Excavation: The area around a well casing is often dug up to a depth of 3 ft to 4 ft, casing is removed at 3ft minimum and above.
Filling and Sealing: Once well is cleared and disinfected, it can be filled and sealed. The well is grouted a foot below the static water level. Process follows by adding disinfected gravel to about 3 ft below the top of the cutoff casing
Capping: Now that the well is filled, sealing (capping) is constructed to prevent surface and near-surface contaminants from enter the casing.
Backfilling: The excavated area around the well casing is filled back up with soil.
Reporting: The final step is to properly report the decommissioned well to New Jersey Department of Environmental Protection (NJDEP)
Why Is It Important To Seal An Abandoned Water Well?
The reasoning behind Sealing an abandoned well is for your safety, as well as the safety of others. Abandoned wells cause hazard to animals, small children, and all homeowners who receive water from the aquifer. The casing of an old, abandoned well is known to rust, it is possible for leaks and it may also fill with debris that causes contamination. Covering the well with boards or concrete is not a recommended solution. An abandoned well that is not sealed properly, is not safe. The boards or concrete used to cover will eventually decay and break open. If that happens, it allows surface water runoff to carry bacteria, organic matter, and other contaminants into the well.
What Is The Cost of Decommissioning And Sealing A Well?
Just like any other environmental service, well decommissioning varies due to a few key factors. These include; accessibility of the well, construction technique that is used for the project, materials (depth, diameter, condition, sand, gravel, concrete, chlorine), the operation costs, etc. An approximation may range from $500 for a shallow/small-diameter well to about $800 or higher for a deep/wide-diameter well.
