Groundwater Wells
|
| A drilling rig is used to drill a well into the groundwater at various depths and locations around the perimeter of a landfill. |
| Groundwater well construction consists of installing piping into the groundwater and then mixing a grout compound to seal off the rock and shale formations above the groundwater table. The piping is usually PVC but can be stainless steel. |
| Groundwater wells are sampled at least twice per year. The well samples are analyzed at a certified lab and reviewed by state and county officials to determine whether the landfill is contaminating groundwater. |
