1,4 D-Stroy uses specialized microbes to provide a low-cost, low-maintenance solution that feeds on 1,4-dioxane and breaks it down into water and carbon dioxide. Allonnia discovered this naturally occurring microbe and optimized it for simple deployment across a variety of environments.
The chemical 1,4-dioxane has been widely used for industrial chemical processes since the 1950s, and the U.S. EPA lists it as one of the most prevalent emerging contaminants and a likely human carcinogen. While there are no federal regulations governing 1,4-dioxane levels in drinking water, wastewater or other water sources, 18 states have established some degree of regulation or recommended guidelines. Regulatory pressures are also growing on a global scale, with the European Chemicals Agency adding 1,4-dioxane to its Candidate List of Hazardous Chemicals in 2021.
Allonnia says that the naturally-occurring organism in 1,4 D-Stroy has proven in ﬁeld tests to degrade 99% of 1,4-dioxane in contaminated groundwater.
The solution requires no capital investment and is delivered onsite via a portable, 18-liter, stainless steel dispersion vessel. The returnable system is designed to dose precise amounts of the microbes to the contaminated water, where they engage with 1,4-dioxane, ingest it, and render it harmless. Initial pilot programs have taken place in Orange County, California, where Allonnia and engineering ﬁrm Stantec eliminated more than 90% of 1,4-dioxane from two contaminated wells in the span of 11 weeks.
“As we see more government attention placed on environmental remediation solutions and techniques, Allonnia is doubling down on our commitment to creating sustainable solutions for 1,4-dioxane bioremediation that can be deployed at scale,” said Chuck Price, Chief Commercial Oﬃcer, Allonnia. “Regulators and government oﬃcials can now consider solutions like this when passing environmental legislation or evaluating 1,4-dioxane limits, and private companies can reduce potential liabilities from contaminated water via a simple-to-use, natural solution.”
