The cause of death has been determined for about 200 cattle that died in a pasture near Chaplin, Saskatchewan.
Poor quality water, combined with hot weather and dehydration were the reasons for the casualties.
Sulphate concentration in the water was 24-thousand milligrams per litre – way over the limit of 1-thousand milligrams per litre. It takes about 7-thousand milligrams per litre to cause death.
At least a handful of the 240 cattle that were still found alive have since died, while other cows and calves are either in a different pasture with a safe water source and being monitored, or are under veterinary care.
At the time of the July 7 incident, the pasture was operated by Shamrock Grazing Limited.
Animal Protection Services of Saskatchewan and Ministry of Agriculture remain active in testing multiple water sources.
