Thousands Of Fish Found Dead In The Yamaska River
They believe that the water in the Yamaska River may be contaminated even though there was no oil spill reported. They also believe that the oxygen levels in the river may have decreased drastically. Christian Blanchette, who works for Urgence-Environment, has stated that they have tested sewers near the river. The results of the tests have been inconclusive.
Christian also believes that low water levels and high temperatures have contributed to the death of the fish. He stated that he was able to cross the river by foot without getting wet. Additionally, Christian believes that the buildup of organic matter in the water led to the death of the fish. Oxygen is needed to break down organic matter.
If there is too much organic matter, then there will not be enough oxygen for the fish. This will eventually cause the fish to die.
