You are tasked with investigating the sudden die-off of salmon in a river in Washington State. The salmon were trying to swim upstream to spawn but died near or just past a dam about halfway along the river's path.
You observe that numerous area farms apply atrazine to their crops at this time of year and that the one dam does employ methods for allowing salmon to move upstream past it.
The water quality data you collected include:
- high levels of sediment at one location near the middle of the river's path by the dam
- low levels of the toxin atrazine at some of the upstream testing locations along the river
- very low levels of dissolved oxygen along the entire downstream half of the river due to recent algae buildup
Which type of water pollution seems MOST LIKELY to have contributed to the sudden death of the salmon and why? Include a description of your chosen type of water pollution.
