Size methods soil remediation

The effectiveness of air sparging as a remediation tool depends on several variables, including soil type, the method of air injection, and the type and concentration of contaminants. The particle size and gradation of a particular soil determine the flow pattern in which the injected air will travel. 

The EPA approved many of the methods published in the Annual Book of ASTM Standards for compliance monitoring under the CWA. ASTM methods used in environmental remediation projects determine soil properties, such as organic content, porosity, permeability, soil grain size, or the properties of free petroleum product contained in the subsurface, such as viscosity, density, and specific gravity.
