Radon in Water Instructions

• Remove any aeration devices or faucet filters from the tap. Run the cold water until fresh water is being drawn from the well.
• Water that has been sitting in a holding tank or the pipes does not contain as much Radon as fresh well water.

• Slowly fill a bowl or deep pan with the spigot underwater. Minimize aeration and splashing.
• Submerge the vial and the cap open side up until they fill with water. While the vial and cap are under water, screw the cap back on tightly. Lift vial out of water and turn it upside down to check for air bubbles. If there is a bubble or an air space, repeat the process. If a double water test was purchased take the 2nd sample from the same supply as the first. If the lab receives the sample with 1 mL or 1g of water missing, about the size of a dime, the test will be invalid.
• Click here or scan the QR code on the instructions and complete the test data form. We cannot calculate your result(s) without the sample collection date and time.

• Mail your sample back to the lab immediately.
• Vial must be received within 7 days of sampling. Please note all CT and NY water samples must be received within 4 days of sampling. A delay in receipt will invalidate your test.
• For the most accurate results, it is recommended that water samples be packaged in a way that prevents either freezing or extreme heat, such as in a cooler or insulated shipping box.
• We recommend that you return your test device(s) via UPS or FedEx due to increasing delays in USPS deliveries, especially around postal holidays. Contact AccuStar for return shipping labels at reduced prices. AccuStar is not responsible for any mail delays resulting in invalid results, nor any costs associated with return shipping. No deliveries are accepted on weekends or holidays.
