The Solution:
- Leachate water treated as of March 2023: >170 ML with zero contractual PFAS exceedances and no issues with complex influent matrix.
Treatment Results:
- Results represent 23 discrete sampling events from January 30 to October 26, 2021. Samples were tested by Eurofins Environment Testing Sweden AB using modified standard DIN 38407-42.

(1) Approx. 500m3 feedwater treated for commissioning phase.
(2) Removal percentage (%R) is calculated by comparing treatment results of feedwater compared to the Site Adopted Criteria.
(3) Removal percentage (%R) is calculated by comparing treatment results to the LOR (1.0 ng/l).
(4) <LOR result is treated as being equal to 99% of the reported LOR.
