An employee of Cargill tampered with three composite treated wastewater samples containing phosphorus by adding a substance to the samples to reduce the amount of phosphorus before they were sent to a laboratory for analysis. Cargill notified Alberta Environment and Sustainable Resource Development of potential errors with its March 2012 wastewater report. The company was fined $80,000 for failing to immediately report the incidents. The employee, who was subsequently fired by Cargill, was fined $7,500 for violating a condition of an approval [Pushp Pal Singh, Govt. News Release, Oct. 22, 2014].
