Mason Regional Park, USA


Mason Lake, California had chronic water quality and blue-green algae issues impacted the health and enjoyment of the waterbody. The lake management firm AquaTechnex selected the proactive solution of Phoslock to address the high levels of phosphorus (water & sediment) and Reset the ecological clock of this lake. The Phoslock application resulted in a 45% reduction in total phosphorus one month after application, a reduction of ortho-phosphorus below limits of detection for 4 months following application and improved water clarity by 4 feet. This first operational application in the United States confirmed the international successes of Phoslock programs and demonstrated the impressive ability of this patented technology to bind phosphorus and restore water quality.
