ERDC TR-13-10 "Cost and Performance Report of Incremental Sampling Methodology for Soil Containing Metallic Residues"

Objectives of this project were to demonstrate improved data quality for metal constituents in surface soils on military training ranges and to develop a methodology that would result in the same or lower cost. The demonstration was conducted at two inactive small-arms ranges at Fort Eustis, VA, and Kimama Training Site (TS), ID, and at one active smallarms range at Fort Wainwright, AK. The samples included 63 Incremental Sampling Methodology (ISM) and 50 conventional grab from Fort Wainwright, 18 ISM and 30 grab from Kimama TS, and 27 ISM and 33 grab from Fort Eustis. The variability in metal concentrations as measured with replicate samples and evaluated using percent relative standard deviation (RSD) were less than 10% for all metals using ISM. In contrasts, RSDs were often greater than 50% for conventional replicate grab samples. Calculated mean ISM metal concentrations were statistically greater than the mean for conventional grab samples.
