    Test Your Water

    You probably know that everything needs water to grow and thrive. But, did you know that what's in the water is just as important?

    We can test your water for you.

    We also offer "packages" that include all the important parameters for different uses, such as for irrigation, watering livestock, and more.

    3. Collect your water sample and label the bottle
      • What type of bottle should you use?
        • The preferred sample collection bottle is a 500 mL bottle that you can pick up at the AWRC WQL or from your local county extension office
        • If you cannot access a preferred bottle, you can buy a 20 ounce or 1 liter bottle of water from the store
        • Note that for bacteria, you must request a sterile sample container from the AWRC WQL.
      • What's the right way to fill the bottle with water?
        • Remove the lid and dump out water if you purchased a bottle from the store
        • Fill bottle half way with sample water, cap the bottle, and swirl around.
        • Dump this water out, away from where you’re collecting it
        • Do this two more times for a total of 3 times (this is called a “triple rinse”)
        • Fill bottle entirely with sample water but leave 1 inch of air space at the top
        • Cap the bottle tightly
      • What should I do to label my bottle?
        • In permanent marker, either directly on the bottle or on a piece of tape stuck to the bottle, write the name of your sample, your name, and the date collected
