This EBC Emerging Contaminants webinar will provide an update on the state of the practice relative to the emerging contaminant 1,4-dioxane. 1,4-Dioxane was included on the 2012 Third Unregulated Contaminant Monitoring Rule (UCMR3) that required monitoring by public water systems during the period from 2013 through 2015.

1,4-Dioxane is a likely human carcinogen that has been used in food additives and laboratory and manufacturing processes. It is also a byproduct of many chemicals used in household products, personal care products, plastics, and polyester, and from the 1950’s to 1996, 1,4-dioxane was commonly used in chlorinated solvents. 1,4-Dioxane releases into the surrounding environment from wastewater discharge, unintended spills, leaks, historical disposal practices of host solvents, and unregulated manufacturing waste streams. These releases have impacted groundwater sites and potable drinking water sources across the country. Since no federal regulations currently exist for 1,4-dioxane, it is often overlooked as a contaminant of potential concern (ITRC, 2020).

This update will focus on the history and uses of 1,4-dioxane, associated sampling precautions, the latest on 1,4-dioxane toxicity, recommendations and options for analytical methods in order to achieve low regulatory criteria, recent changes in our understanding of the biodegradability of 1,4-dioxane, and treatment options for this chemical.

A robust panel discussion with the audience will conclude the webinar.

Massachusetts Licensed Site Professional (LSP) Technical Credit: EBC has applied to the Massachusetts LSP Board for 2.0 hours of technical credit. If credit hours are approved by the LSP Board this webpage will be updated.

General Continuing Education Certificates are awarded by the EBC for this program (2.5 training contact hours). Certificates are automatically provided via email link for registered attendees at the conclusion of the webinar.
