CarbonRun’s Kvina River Project augmented the existing dosing operations from June 10 to September 15, 2025 (97 days), targeting elevated pH conditions to a target pH of 7.0. The project dosed approximately 1749 tonnes of calcium carbonate in total, with 1480 tonnes representing additional dosing above the baseline liming requirements.
