Annual Conference

Pre-Conference: “The Coming Wave: 1,4-Dioxane Background, Treatment Strategies, and Waste-Stream Management Strategies”

Presented and sponsored by: H2M Architects & Engineers 

Course Description: 
This course provides a comprehensive understanding of 1,4-Dioxane, its treatment, and waste management strategies. It begins with a historical background, toxicology, and regulatory framework for 1,4-Dioxane. The course then discusses treatment alternatives and waste stream management. The final module focuses on real-world examples and lessons learned from the startup and commissioning of 1,4-Dioxane treatment systems. Participants will gain insights into the design criteria for treatment technologies and the implementation of UV/AOP treatment approaches. The training concludes with a review of lessons learned and a comparison between theoretical design targets and actual water quality outcomes.

Agenda:
 
8:00 – 9:00 AM              Morning Refreshments and Sign-in
9:00 AM                             Training Begins
 
Module 1: “Historical Background, Toxicology, and Regulatory Framework for 1,4-Dioxane”
 Duration: 70 minutes

• Scope Narrative: Presenters will review the historical context for the invention of PFAS, its originally intended purposes and functions, and how it became ubiquitous in the natural aquatic environment.  A survey of known information in the field of toxicology will be conducted, discussing NJDEP’s approach to testing and validating candidate primary contaminants and potential MCL’s – via its partner board, the NJ Drinking Water Quality Institute.  This module will close with a synthesis of this background information into the current 1,4-Dioxane regulation enforce in NY State, and a dialogue about potential implementation in New Jersey.”

Break: 15 minutes
 
Module 2: “Treatment Alternatives and Waste Stream Management for 1,4-Dioxane”
 Duration: 70 minutes

• Scope Narrative: The presenting team will review the design criteria for candidate treatment technologies for removal and/or destruction of 1,4-Dioxane.  The focal point of this module will be a description of the design parameters, boundary conditions, and water quality targets for the implementation of the UV/AOP treatment approach (combination of ultraviolet light and advanced oxidation process).  A discussion will be conducted regarding management of treatment process waste mass flows.

Break: 15 minutes
 
Module 3: “Implementation Workshop – Discussion of Real-World Examples and Lessons Learned from
Startup/Commissioning of 1,4-Dioxane Treatment”
 Duration: 70 minutes

• Scope Narrative: The presentation will close on a third module, focused on narratives of the process of due diligence, design, permitting, construction, and systems commissioning for actual, full-scale 1,4-Dioxane treatment systems.  Several examples will be given, using various water qualities.  A review will be conducted of lessons learned, and a comparison made between theoretical design targets and actual water quality outcomes, based on 1+ year of operating data.
