Invicta Water – Case Study – March 2024
Project Overview
Invicta Water was tasked with the opportunity to clean a large commercial real estate parcel in northern Wake County, North Carolina. This private property is a former industrial site, containing multiple contaminated retention ponds. To achieve development approvals, these ponds require draining and remediation of approximately 10 million gallons of water.
The property owner previously identified PFAS contamination within the retention ponds.
Our Process
Invicta Water collected water samples from the site to evaluate our ability to help the property owner remediate the PFAS.
We then treated the water using our proprietary Photo-Catalytic Destruction System, which first captures the PFAS compounds from water, and in-situ, ultimately destroys the compounds for permanent remediation, leaving no toxic or harmful byproducts behind. NOTE: Invicta Water received and treated the water without any prior knowledge of PFAS type or ability to optimize for compound destruction.
After treating the water, we sent both untreated and treated samples to a verified 3rd party testing laboratory for evaluation via ASTM D8421.
Results
The following results are provided by the independent testing lab. These results verify the efficiency with which our system captures and destroys PFAS compounds, leaving behind clean water and no further contamination nor waste stream:
- 10 unique PFAS compounds were identified in the untreated water sample, including 4 of the EPA top 6 for proposed drinking water regulation (highlighted in yellow in the table)
- The PFAS compounds found in the untreated water contained a wide range of 32 to 13,345 ppt, measuring 24,174 ppt in aggregate, with each of the compounds found to be well above recommended, required, and proposed safe levels
- After applying Invicta Water’s Photo-Catalytic Destruction system, 8 of the 10 PFAS compounds were eliminated to a non-detect level, at a threshold of 5 ppt.
- Uniquely, of the 4 EPA target PFAS found, our system was able to eliminate 3 entirely and 99.91% of the 4th without optimizing for specific compound destruction
In sum, Invicta Water was presented with water containing 24,000 ppt in aggregate of multiple PFAS compounds. Untreated, this water is uniquely unsafe for human use and consumption.
The Invicta Water Photo-Catalytic Destruction system was able to capture the PFAS from the water and then destroy it cleanly to unmeasurable levels, leaving nothing but clean water behind.
To complete the remediation at this property location, our mobile system would easily be implemented at an optimum level to destroy all of the identified compounds to unmeasurable levels, and leaving no further materials or toxic waste requiring handling.
