Radon in Water Mitigation By Aeration

Aeration is recognized by the EPA as the “BAT” or; Best Available Technology for radon in water mitigation.  The primary advantages of aeration are: 1) no build up or collection of radioactivity, #2) consistent removal efficiency #3) improved water pressure, and pH adjustment.

CT Basement was the first CT based radon mitigation company to offer waterborne radon removal.  We installed our first aeration system in early 1988.  A lot has changed in the residential aeration system market.  The first generation aeration systems we installed were manufactured by North East Environmental Products (NEEP) out of New Hampshire.  Their 3311 shallow tray aeration system was an adaption from packed tower aeration systems that were utilized to aerate municipal supplies.  Re-pressurization of treated water was accomplished by a conventional shallow well jet pump and pressure.  These systems were capable of up to 99% removal efficiencies

In late 2003, we began installing aeration systems that offered a built – in submersible pump. Getting away from the shallow well jet pump re-pressurization configuration made an appreciable difference in operational noise, water pressure delivered, and footprint of systems.  Since then, RE Prescott – Bubble Up, and Spruce – AiRaider, have made several improvements to include overflow protection, variable frequency drive re-pressurization, and larger tank options while delivering up to 99% removal efficiencies.  Below are pictures of various system installs we’ve done.


When choosing an aeration system for radon in water mitigation, radon in water levels, size of house, size of area where system is to be located, and even the size of the family living in the home, are all factors that should be taken into consideration.  Our experienced staff of radon and water professionals can help guide you to the best decision for your particular application.

Any aeration system bubbles and / or sprays the water in some fashion to separate the radon from water.  Radon is “water phobic” and readily off-gasses. The radon that separates from the water is safely vented out of the unit to the roof line of the home.  The treated water is stored at atmospheric pressure within the aeration tank and needs to be re-pressurized. A re-pressurization pump will draw the water out of the tank and send it to point of use.

Make no mistake; any aeration system is a mechanical device that requires regular servicing to optimize system life.  Regardless of manufacturer, and even with regular servicing, there are things that will eventually go wrong with the system. Including solenoids, float level switches, blowers, and pumps.  It is also important to maintain good water quality being supplied to the aeration system.  Elevated iron or manganese, hardness, and sediment are all things that will create issues with an aeration system.  We have the most collective experience under one roof to ensure we keep your system up and running efficiently.

Radon Awareness Month

Radon Awareness Month 2020 is here. We’ve been mitigating elevated radon concentrations in private residences, schools, and commercial buildings since 1987…before there was ever an “Awareness” month. Our project experience runs deep,and we’ve pretty much seen it all at this point. Anyone can acquire the required class time, and pass the test to become a State listed “qualified” mitigation professional. But the difference between us and our competitors is experience. There are simply no companies in CT with the combined experience we possess under one roof. We’ve mitigated indoor airborne radon concentrations of 900 pCi/l, and waterborne radon concentrations of 1,000,000 pCi/l!

It’s no secret that radon is the second leading cause of lung cancer…first among non-smokers. We’ve spent decades working to deliver the lowest airborne and waterborne radon exposures to our customer base. Radon has no bias. New construction, antiques, slab – on – grade, contemporaries, traditional, commercial, and any style, type, size or aged building you can think of, can be subjected to elevated airborne radon concentrations.

Great strides have been made in reducing cancer deaths in the US. This reduction is attributable in large part to the improvements in lung cancer treatment. The American Lung Association recognizes radon exposure as a main contributor to lung cancer incidences among non-smokers. Finding these problems and fixing them before they can make someone sick is the best preventative measure to take.
