How to Test Water Turbidity for Environmental Studies

The video tutorial explains how suspended debris like sand or silt affects water clarity by blocking sunlight and smothering aquatic habitats. It provides a step-by-step guide on setting up a turbidity test using a sampling jar and a turbidity scale. The process involves comparing the appearance of a disk inside the jar to a chart to determine the turbidity level, which is recorded in JT units.

What is one of the effects of debris suspended in water?

• It creates more habitats for fish.

• It increases the oxygen levels in water.

• It prevents sunlight from reaching aquatic plants.

• It enhances the growth of aquatic plants.

What should be attached to the bottom of the sampling jar?

• A transparent sticker

• A small circular black and white decal

• A blue and white decal

• A red and white label

What is the purpose of filling the jar to the fill line with water from the site?

• To measure the water's temperature

• To ensure the jar is clean

• To test the jar's durability

• To prepare for turbidity measurement

How do you determine the turbidity value using the scale?

• By comparing the disk's appearance to the chart

• By measuring the water's temperature

• By observing the water's smell

• By checking the water's color

What are the possible turbidity values mentioned?

• Twenty, sixty, or one hundred

• Zero, fifty, or one hundred

• Zero, forty, or one hundred

• Ten, forty, or ninety
