Green Prairie International Lincoln, NE
Johnson Controls is under contract with Pfizer to provide process control and maintenance services at this site, and is responsible for upkeep on this 8 acre lake. In the last several years, the site manager, Mr. Steve Amos, has utilized a variety of algae control methods, such as copper addition and herbicides. Despite these efforts, the lake condition has continued to deteriorate. By late April 2012, particularly with an unusually warm spring and abundant sunshine, the lake was highly odorous, and was 30 to 50% covered with algae. Because past chemical and physical treatments proved ineffective, Johnson Controls / Pfizer elected to use the ComboPack System, manufactured by TLC Products in Cleveland, OH.
