Challenges in Surface Water Management

Surface water is a primary drinking source in Southeast Queensland, collected from rainfall in catchments and stored in dams. It undergoes treatment to ensure safety, but challenges arise during heavy rain or droughts, affecting quality and cost. Factors like recreation, vegetation, and construction also impact water quality. Resilience is crucial, as climate change may increase droughts and floods, complicating management and treatment.

What is the primary source of drinking water in Southeast Queensland?

• Groundwater

• Surface water

• Desalinated water

• Bottled water

What is a common method of storing surface water?

• Aquifers

• Reservoirs

• Tanks

• Dams

Why is it challenging to treat surface water during heavy rain?

• Increased sediment and mud

• Increased water temperature

• Increased algae growth

• Decreased water flow

What happens to water quality when there is less rain?

• Water temperature decreases

• Sediment levels drop

• Algae growth increases

• Water becomes clearer

Which of the following is NOT a factor affecting sediment levels in water?

• Wind speed

• Nearby developments

• Vegetation

• Recreation

What does resilience of surface water refer to?

• Its ability to remain clean

• Its management during disruptive events

• Its cost-effectiveness

• Its availability for recreation

How does climate change affect surface water management?

• Decreases water demand

• Decreases sediment levels

• Increases water temperature

• Increases frequency of droughts and floods

What impact does recreational use have on surface water?

• Has no impact

• Reduces treatment costs

• Improves water quality

• Increases water quality and treatment costs

Why is maintaining consistent water quality challenging?

• Due to varying sediment levels

• Due to high production costs

• Due to limited water sources

• Due to constant water temperature

What is a key consideration besides quality for surface water?

• Color

• Resilience

• Cost

• Taste
