Abstract
A groundwater remediation method for treating acidic or alkaline groundwater containing divalent and trivalent metal cations includes the step of injecting a slurry or suspension of solid alkaline material into the ground, the slurry or suspension being injected into one or more regions such that the groundwater contacts the solid alkaline material and the divalent and trivalent metal cations react to form a layered double hydroxide (LDH) material.
