DoD Perchlorate Handbook, Revision 1, Change 1 August 2007

The Department of Defense (DoD) Environmental Data Quality Workgroup (EDQW) prepared the DoD Perchlorate Handbook to assist DoD facilities in complying with current DoD policy governing perchlorate sampling and testing activities for both environmental restoration/cleanup and compliance monitoring programs. Intended users of this document include DoD Remedial Project Managers (RPMs), contractor project managers, and field-sampling personnel. This handbook includes guidance on the following:

  • Using conceptual site models (CSMs) to develop project quality objectives (PQOs) associated with sampling and analysis for perchlorate,
  • Designing sampling strategies and implementing appropriate sampling techniques,
  • Selecting qualified analytical laboratories and analytical methods, based on required performance objectives, and
  • Documenting the above in project planning documents in accordance with the Uniform Federal Policy for Quality Assurance Project Plans, March 2005 (UFP-QAPP).

The Handbook was revised May 2007 to:

  • Reflect the release of EPA Methods 6850 and 6860
  • Remove references to UCMR 2
  • Remove information about proposed changes to methods associated with UCMR 2
  • Update Appendix G to be consistent with Methods 6850 and 6860
  • Update Appendix G Quality Control requirements.

The Handbook was changed in August 2007 to update some referenced links to websites and fix a few editorial errors

Sampling and Testing for Perchlorate at DoD installations Interim Guidance, February 2004

The 29 September 2003 Interim Policy directed DoD Components to continue to consolidate data on the occurrence of perchlorate at active and closed installations, ranges, and Formerly Used Defense Sites (FUDS). The < Interim Testing and>provides interim guidance developed by the Department of Defense Environmental Data Quality Work Group (EDQw) to assist Components in complying with the Interim Policy. In particular, the guidance is intended to alert installations and data users about the limitations of currently approved EPA Methods 314.0 and SW 846-9058 (draft), the potential for false positives, and the need to verify results by alternate, definitive performance-based methods, such as those employing Mass Spectrometry technology.

The EDQW is in the process of developing detailed guidance for the characterization of perchlorate under Environmental Restoration and Range Assessment programs, expected to be issued late in FY 04.

The Agency for Toxic Substances and Disease Registry (ATSDR) has released a final perchlorate toxicological profile. The 299 page profile discusses health effects public health risk of perchorate exposure. The profile includes a Minimal Risk Level for oral exposures with a chronic reference dose (RfD) of 0.0007 mg/kg/day for the chronic oral MRL for the perchlorate anion. This value is based on a 2005 National Academy of Sciences report and is the value that EPA has also adopted. The results from newer studies did not change ATSDRs bottom-line recommendation.

Parker, et al. (2008) Perchlorate in groundwater: A synoptic survey of pristine sites in the coterminus United States. Environ. Sci. Technol. 42(5): 1465-1471. Authors used a network of volunteers to collect 326 groundwater samples, avoiding areas of EAP-documented use or release. Of the 326 samples, 147 (45%) were below the method detection limit (40 ng/L), 42 (13%) were between the MDL and the method reporting limit (120 ng/L). Of the 137 samples that could be quantified, most (109) contained less than 1000 ng/L of perchlorate; the remaining 28 contained from 1000-10,400 ng/L. Perchlorate concentrations were positively-correlated with nitrate levels, but not with chloride concentrations.

Tran, N., et al. (2008) Thyroid stimulating hormone increases active transport of perchlorate into thyroid cells. Am J. Physiol Endocrinol. Metab., 26 Feb 2008 (e-pub ahead of publication). Using an in vitro system, authors found that perchlorate is actively transported into thyroid cells, and this transport increases in a dose-related manner when treated with TSH. Addition of iodine appeared to competitively-inhibit perchlorate transport. The highest concentration of perchlorate, 100 micromole/L, did not inhibit cell proliferation over a 72 hour period.
