Measuring Nitrates and Phosphates in Waterways to Prevent Dead Zones

The video tutorial explains the impact of excess nutrients like nitrates and phosphates on water bodies, leading to dead zones. It demonstrates how to test for these nutrients using specific equipment. The process involves measuring water samples, adding solutions, and using meters to get readings. The results help determine the nutrient levels and their potential impact on algae growth.

What is a major cause of dead zones in waterways?

• Low water temperature

• High salinity

• Decreased oxygen levels

• Increased nutrient load

Why is it important to test for nitrates in water?

• They increase water clarity

• They are a source of oxygen

• They reduce water temperature

• They can cause algae blooms

What was the nitrate level reading in the water sample?

• 0.02 mg/L

• 1.00 mg/L

• 0.29 mg/L

• 0.50 mg/L

What common household products contribute to phosphate pollution?

• Detergents and cleaners

• Beverages

• Fruits and vegetables

• Clothing

What was the phosphate level reading in the water sample?

• 0.29 mg/L

• 0.50 mg/L

• 1.00 mg/L

• 0.02 mg/L
