Perchlorate Training Courses
The Perchlorate training courses address water and soil contamination by perchlorate and the selection and implementation of remedial technologies.
Perchlorate contamination exists in water and soil and occurs widely throughout the United States. Public awareness and concern regarding perchlorate has increased in recent years. Perchlorate occurrence in drinking water and food supplies is a human health concern because it can interfere with iodide uptake by the thyroid gland and result in decreased thyroid hormone production. The ITRC Perchlorate Team was formed in 2004 to address technical issues associated with perchlorate. Many technologies are available to remediate perchlorate contamination, but only a few are commonly used.
This training introduces state regulators, environmental consultants, site owners, and community stakeholders to Remediation Technologies for Perchlorate Contamination in Water and Soil (PERC-2, 2008), created by ITRC's Perchlorate Team to assist reviewers in assessing the adequacy of perchlorate remediation projects. This course gives the student a background in the available remediation technologies to treat perchlorate contamination, discusses emerging technologies, and presents case studies of applications.
The first document produced by the ITRC Perchlorate Team, Perchlorate: Overview of Issues, Status, and Remedial Options (PERC-1, 2005) and associated Internet-based training provide regulators and other stakeholders a basic overview of a broad spectrum of information regarding perchlorate sources, sampling and analysis techniques, a discussion of risk issues, risk management strategies and regulatory status, and a brief summary of remediation technologies. It is recommended that the registrant review the Perchlorate: Overview of Issues, Status, and Remedial Options (PERC-1, 2005) document and associated Internet-based training archive for more information.
Perchlorate is an inorganic chemical ion consisting of chlorine bonded to four oxygen atoms (ClO4–). It occurs both naturally and in manmade compounds. While it was once thought to occur naturally only in one location, ongoing study has found naturally occurring perchlorate in other locations as well. In manmade compounds, it has been manufactured since before the turn of the last century and has been manufactured primarily for use in defense activities and the aerospace industry. Highly soluble and mobile in water, perchlorate is also very stable. Most of the attention focused on perchlorate contamination concerns ground and surface water contamination. However, it can also contaminate soil and vegetation. In general, past management practices did not prevent the release of perchlorate to the environment because it was not recognized or regarded as a contaminant of concern. Improved analytical methodology has increased the known extent of perchlorate contamination in the United States. A variety of remediation technologies are currently commercially available and being used for perchlorate remediation.
This training, based on ITRC's Perchlorate: Overview of Issues, Status, and Remedial Options (PERC-1, September 2005), explains why perchlorate is a hot topic in the environmental community today including up-to-date information on sources, occurrences, toxicity and exposure, regulatory status, and remediation alternatives.
