 Today, I'm going to demonstrate a simple way to collect a water sample for quality testing. Microbial water testing is important to determine the safety of the water that is being used to irrigate produce fields. So, a representative sample should be taken periodically to examine the quality of the water. Before you start sampling, call the lab that will be receiving your sample to make sure they will be able to process the sample when you bring it to them. Most labs will also have guidelines on how fresh the water samples should be, so be sure to ask them if you think you might need to hold the sample before bringing it to the lab. Using disposable gloves or clean hands, sanitize the faucet inside and out with an alcohol prep pad or undiluted chlorine bleach to make sure you don't have contaminants going into your bottle. Open the tap fully and let the water run for about 3 minutes to flush the faucet in pipes. After 3 minutes, reduce the flow to avoid splashing when sampling. Then, uncap the sterile sample bottle without touching the inside of the bottle. Then, recap. Place the bottle inside of a cooler with ice packs and send it over to the lab. Make sure you have labeled the bottle with the name of the form or water source date, end time or sample. We hope this video was very useful.
