Perchlorate Peer Review Meeting Set for January

As part of the continuing process to understand the impact of perchlorate on human health and develop information that can be used in the regulatory development process, EPA has formed another peer review panel that will meet in January 2018 to examine the scientific material in the “Draft Report: Proposed Approaches to Inform the Derivation of a Maximum Contaminant Level Goal for Perchlorate in Drinking Water” (draft MCLG Approaches Report).  The public peer review meeting will be held on January 29 and 30, 2018. The meeting will be held from approximately 8:30 a.m. to 5 p.m., eastern time, on January 29, and from approximately 8:30 a.m. to 3 p.m., eastern time, on January 30.  The meeting can be observed in person (in Arlington, VA) or remotely.
During the meeting the peer review panelists will evaluate and prepare written comments on the draft MCLG Approaches Report. Specifically, reviewers will provide general comments, their overall impressions of the document, and responses to charge questions. Reviewers will also consider the appropriateness of the quality, accuracy, and relevance of the data in the document.  The specific charge questions cover four areas:

  • General questions on the focus of the evaluation and new studies that should be considered.
  • BBDR modeling to predict changes in thyroid hormone levels in early pregnancy
  • Identification of published literature and quantitative relationship of thyroid hormone levels to neurodevelopmental outcomes
  • Alternative population-based approach and comparison to the two-stage approach linking thyroid hormone levels to neurodevelopmental outcomes
