Demonstration and Validation of a Regenerated Cellulose Dialysis Membrane Diffusion Sampler for Monitoring Ground-Water Quality and Remediation Progress at DoD Site: Perchlorate and Ordnance Compounds.

摘要

This cost and performance report documents the demonstration and validation of regenerated cellulose dialysis membrane (RCDM) samplers for use in collecting groundwater samples for perchlorate and a suite of explosives compounds. The primary objectives of the project were (1) to determine the usefulness of RCDM samplers in collecting perchlorate and a suite of explosives compounds from groundwater, (2) to determine the optimum equilibration times for these constituents to diffuse into the RCDM sampler, (3) to compare water- quality results and sampling costs from samples collected with RCDM samplers to samples collected with a low-flow purging technique, and (4) to transfer the technology while gaining regulatory acceptance. Equilibration times were determined in bench-scale testing for perchlorate and 14 nitroaromatic and nitramine explosives compounds. Field comparisons were conducted at two Department of Defense (DoD) sites: Aberdeen Proving Ground (APG), MD and Picatinny Arsenal, NJ. Samples collected with the two sampling techniques were compared graphically and statistically to determine the significance of any differences found.
