Question

What is a secure chemical landfill

Answer 1

Organic wastes (materials derived of living organisms or hydrocarbons such as oil) are chemically oxidized prior to land disposal and various proprietary stabilization techniques are used for metal-bearing waste rendering an insoluble, solid material for safe landfill disposal.

Answer 2

A secure chemical landfill is a carefully engineered depression in the ground (or built on top of the ground, resembling a football stadium) into which wastes are put. The aim is to avoid any hydraulic [water-related] connection between the wastes and the surrounding environment, particularly groundwater.
