Water Quality Testing Procedures

The video tutorial by Professor Hen Zan covers the importance of water testing for human, livestock, soil, and plant quality. It explains the types of water tests available, including livestock, irrigation, and household water tests. The tutorial provides detailed instructions on how to collect water samples for different purposes and how to analyze them. It also discusses the interpretation of water test results, comparing them with EPA standards, and introduces an advanced program for better interpretation of test results. The video emphasizes the need for certified labs for certain tests and provides resources for further information.

Why is water quality testing important for both humans and livestock?

• To find out the temperature of the water.

• To measure the water's pH level.

• To determine the color of the water.

• To ensure the water is safe for drinking and consumption.

What is the first step in collecting a water sample for domestic use?

• Use any available container.

• Collect water directly from a river.

• Let the faucet run for a few minutes.

• Boil the water before collecting.

What should you do to test for E. coli in tap water?

• Use a plastic bag to collect the sample.

• Boil the water first.

• Collect water from a lake.

• Use a bottle with a sterile pellet inside.

How should you collect a water sample to test for lead or copper contamination?

• Let the water run for a long time before collecting.

• Collect water from a well.

• Collect the water immediately as it starts running.

• Use a plastic container.

What is the significance of nitrate levels in water testing?

• Nitrate levels are irrelevant to water quality.

• Nitrate levels affect the water's temperature.

• High nitrate levels can make water unsafe for drinking.

• Nitrate levels determine the water's color.

What is the EPA's standard for nitrate levels in drinking water?

• Less than 10 parts per million.

• Less than 15 parts per million.

• Less than 5 parts per million.

• Less than 20 parts per million.

What is the purpose of comparing water test results with EPA standards?

• To measure the water's pH level.

• To find out the water's temperature.

• To ensure the water meets safety guidelines.

• To determine the water's color.

What additional resources are available for interpreting water test results?

• Public libraries.

• Local grocery stores.

• County Extension Offices and online programs.

• Local schools.

How can you find more information about why nitrate is considered a contaminant?

• By reading books on chemistry.

• By visiting the County Extension Office or online resources.

• By watching a movie.

• By asking a friend.

What should you do if you need more information on different water tests?

• Ask a neighbor.

• Visit your County Extension Office.

• Contact the local fire department.

• Check the weather forecast.
