EPA Proposes Comprehensive Cleanup of 1,4-Dioxane at NJ Superfund Site
1,4-Dioxane1,4-dioxane is a volatile organic chemical often found at chemical manufacturing facilities, such as those previously at the CPS/Madison Superfund site. It is a clear, colorless liquid that is commonly used as a stabilizer in certain chlorinated solvents, such as paint strippers, greases, and waxes. Because it is water soluble, 1,4-dioxane can easily leach into water sources and is resistant to biodegradation, making it a challenge to remove from groundwater.
EPA cites 1,4-Dioxane as a likely carcinogen through all routes of exposure. Although no Federal maximum contaminant level has been established, EPA has determined less than 4 mg/L concentration of 1,4-dioxane in drinking water is not likely to impact our health. The Occupational Safety and Health Administration (OSHA), however, established a Federal limit of 100 parts per million when workers are exposed to 1,4-dioxane in the air.
CPS/Madison Superfund Site Remediation1,4-Dioxane requires complex site remediation strategies, EPA notes in the proposal. Workers will need to excavate and relocate roughly 900 cubic yards of contaminated soil from the CPS/Madison Superfund site to a specialized treatment center, where it will be remediated via oxidation.
Soil that has been exposed to organic contaminants other than 1,4-dioxane will be treated with chemical oxidants, breaking down the hazardous chemicals into water and carbon dioxide.
Contaminated groundwater would go through a similar process in which an oxidant is pumped into the groundwater. EPA would also use a line of wells to create a reactive barrier, destroying the organic chemicals as they pass through. EPA also plans to monitor the groundwater for several years afterwards to ensure that the site will no longer be a source for contamination and will perform a full review every five years to ensure the cleanup’s effectiveness.
EPA has also instructed the NJ Department of Environmental Protection to monitor the water supply of neighboring Perth Amboy to ensure the safety of its municipal water supply.
EPA is currently accepting comments via e-mail here until May 24. The public may also submit written comments to: John Osolin, Remedial Project Manager, U.S. Environmental Protection Agency, 290 Broadway, 19th Floor, New York, NY 10007.
HAZWOPER Training – Anytime, AnywhereHazmat techs are required to undergo Hazardous Waste Operations and Emergency Response (HAZWOPER) training if they work in one of three activities:
- Work at an environmental cleanup site (e.g., Superfund cleanup site)
- Work at an EPA or state-permitted hazardous waste TSDF
- Responding to releases of hazardous materials
Ensure you and your team know what to do for the next HAZWOPER incident and keep in compliance with OSHA’s HAZWOPER standard with Lion’s 40 Hour HAZWOPER Initial Contaminated Site Cleanup online training. This course is specially designed for general workers such as equipment operators, laborers, and supervisors who need initial site cleanup training with the flexibility to start, pause, and complete the course at their own pace, wherever they are.

Much better than my previous class with another company. The Lion instructor made sense, kept me awake and made me laugh!
Enterprise Safety Manager
Lion courses are the standard to which all other workshops should strive for!
Registered Environmental Health Specialist
I was able to present my scenario to the instructor and worked thru the regulations together. In the past, I attended another training firm's classes. Now, I have no intention of leaving Lion!
Senior Environmental Engineer
Lion does a great job summarizing and communicating complicated EH&S-related regulations.
Sr. Environmental Engineer
I used the IT support number available and my issue was resolved within a few minutes. I don't see anything that could have made it better.
The course was very informative and presented in a way that was easily understood and remembered. I would recommend this course.
Hazmat Shipping Professional
These are the best commercial course references I have seen (10+ years). Great job!
EHS & Facility Engineer
My experience with Lion training, both online and in the classroom, is that they are far better organized and provide a better sequential explanation of the material.
Manager, Dangerous Goods Transportation
This is the best RCRA training I've experienced! I will be visiting Lion training again.

Principal Environmental Engineer
I think LION does an excellent job of any training they do. Materials provided are very useful to my day-to-day work activities.
