A recent study focused on the > 2mm size fraction of an urban soil suggests milling does result in a significant concentration increase of many trace metals . The two commonly used EPA methods 3050 and 3051 employ nitric and hydrochloric acids on a hot block (3050) and in open vessels in a microwave (3051) to dissolve metals for later analysis.

The ball milling method has been used in the remediation of both organic and inorganic contaminants. In the ball milling method, a cylindrical container housing steel balls and the material is rotated, and the impact of balls with soil particles reduces the particle sizes and a reaction takes place at the surface of the ball mill.
