Case Studies

PERMEOX® Ultra and PERMEOX® Ultra Granular

PERMEOX® Ultra provides a long‑lasting oxygen supply through its engineered calcium peroxide formulation, enhancing aerobic bioremediation in soil and groundwater. Its controlled oxygen release supports the effective degradation of petroleum hydrocarbons and other biodegradable, non‑halogenated contaminants. The following case studies show how PERMEOX® Ultra can strengthen natural attenuation, improve treatment performance, and offer a cost‑efficient approach for in situ remediation projects.

PERMEOX® Plus Used for Remediation of Former UST Leakage

This case study highlights the successful enhanced bioremediation of petroleum‑contaminated soil and groundwater at a former UST site using PERMEOX® Plus. Its engineered calcium peroxide formulation increased dissolved oxygen levels through targeted chemical injection across direct‑push points and permanent wells, supporting sustained aerobic degradation of BTEX compounds. Contaminant concentrations in the most impacted soils dropped from 1,400 µg/L to near nondetect within four months. The approach minimized site disruption and delivered significant cost savings compared to alternative remediation methods.

KLOZUR® (Sodium Persulfate) and PERMEOX® Plus Used to Remediate Groundwater at Former Oil Refinery Pipeline Release

This case study describes how ORIN remediated petroleum‑impacted groundwater at an oil refinery pipeline release using a combined KLOZUR® SP (sodium persulfate) and PERMEOX® Plus approach. Targeted chemical injection across direct‑push points enhanced oxidation and aerobic biodegradation of benzene within the plume. Concentrations decreased from 4,700 µg/L to near nondetect within four months. The method minimized site disruption and delivered substantial cost savings compared to alternative remediation strategies.

Chemical Oxidation and Biostimulation Achieves Significant Plume Reduction with Single Amendment Application in Florida

PERMEOX® Plus delivered rapid and sustained in situ groundwater remediation at a gasoline‑impacted site in Florida, achieving Florida Groundwater Target Cleanup Goals within three months and maintaining them through four consecutive monitoring events. By releasing long‑lasting oxygen, PERMEOX® Plus effectively stimulated native aerobic microbes, accelerating biodegradation of petroleum hydrocarbons across the dissolved plume.

The treatment significantly reduced plume size—by 70% within the PERMEOX® Plus zone—and supported a smooth transition to natural attenuation processes. This case study highlights how the engineered calcium perocide product PERMEOX® Plus enables fast, reliable, and cost‑effective in situ bioremediation.
