Water had more than 3 times the lethal concentration of sulphate
Lab results have determined the death of 200 cattle in a grazing pasture near Shamrock, Sask., earlier this month was caused by a combination of dehydration, poor water quality and heat, according to a statement released Thursday by the province.
Sulphate levels in the water were more than three times the lethal concentration, at 24,000 milligrams per litre. Concentrations of 1,000 milligrams per litre are enough to cause neurological trauma, while levels of 7,000 milligrams or more can result in death.
