Detection and Site Characterization

The purpose of this section is to identify analytical and sampling methods commonly used for detecting, measuring, and/or monitoring mercury that are available on line. The intent is not to provide an exhaustive list of analytical methods, but to identify well-established, standard methods, particularly those used for environmental samples and approved by EPA.

Check the National Environmental Methods Index (NEMI) to locate EPA methods not included on this page.

U.S. EPA, National Exposure Research Laboratory.

The toxicity and environmental mobility of different inorganic mercury compounds is closely related to their relative solubilities in aqueous media, so a sequential extraction procedure utilizing increasingly powerful aqueous solvents should permit the separation of mixtures of mercury compounds into operationally defined classes with different potentials for human and ecological exposure. The results of such a speciation should permit a more accurate assessment of the mercury hazard associated with a particular site than is currently provided by determination of total mercury.

Environmental Forensics: Contaminant-Specific Guide
Robert D. Morrison and Brian Murphy.
Elsevier Academic Press, Boston. ISBN: 0125077513, 576 pp, 2006

Environmental forensics is the application of scientific techniques for the purpose of identifying the source and age of a contaminant. This book discusses the following contaminants and contaminant groups: mercury, asbestos, lead, chromium, methane, radioactive compounds, pesticides, perchlorate, polychlorinated biphenyls, arsenic, chlorinated solvents, polyaromatic hydrocarbons, crude oil, gasoline, microbes, and compounds found in sewage.

Adobe PDF LogoHigh Resolution Passive Soil Gas Sampling for Elemental Hg Characterization
Cole, J., G. Schaefer, and J. Hodny.
NICOLE Technical Meeting, 4 December 2012, Brussels, Belgium. 24 slides, 2012

A wide-scale initial field assessment of elemental Hg can be conducted through the use of a soil vapor sampling technique that is relatively cheap and easy to apply over large areas. A case study illustrates how application of a passive soil vapor survey allowed investigators to access difficult areas for an initial screening and refine the number of soil boreholes potentially needed from >300 boreholes to 20. The soil-gas sampling results can be used to refine and select high-impact or potential source areas for the more expensive soil (borehole) sampling and analysis.

Mass Flux Toolkit to Evaluate Groundwater Impacts, Attenuation, and Remediation Alternatives
Environmental Security Technology Certification Program (ESTCP), 2006

To help site managers and site consultants estimate mass flux and understand the uncertainty in those estimates, ESTCP has funded the development of a computerized Mass Flux Toolkit, free software that gives site personnel the capability to compare different mass flux approaches, calculate mass flux from transect data, and apply mass flux to manage ground-water plumes. The toolkit spreadsheet and associated documentation are available on the ESTCP contractor's website in a zipped file.
