Radon in Water Testing


Aquatek has been providing quality radon analysis for over 20 years. We provide both single and dual test kits for detecting radon in water. Radon in water test kits are ideal for anyone who wants a quick, accurate and inexpensive way to estimate the radon level in their drinking water.


In most homes and buildings the primary lung cancer risk results from breathing air contaminated with radon gas entering through openings in the foundation or slab. In homes that use private wells, radon in water may contribute to the radon exposure and resulting lung cancer risk. Occupants of these homes will be inhaling radon gas that leaves the water during showering and other water uses. There is still controversy over the risk associated with ingested radon and there is continuing research in this area.


Radon is a radioactive gas which occurs in nature as a result of the radioactive decay of uranium. Uranium is a radioactive element found in rocks and dirt deep beneath houses and buildings. As the Uranium breaks down it decays into radon. Some of that radon can diffuse into the ground water from which you drink. Radon is then released into the air as water flows into sinks, tubs, and appliances. Household activities that use hot water, such as showering and washing dishes or clothes, can release large amounts of radon particularly in the rooms where this water is used.


There is currently no federal standard for radon in water. However, the Connecticut Department of Public Health has a recommended guideline of 5,000 pCi/L in private well water. This is only a guideline with no statutory or regulatory authority. Most authorities do not recommend treatment based on a single sample result. Radon levels in water can vary significantly over time. Therefore it is important to obtain at least two sample results before deciding to install a treatment system. These samples should be taken at least three months apart.
