Your First Choice for Waterborne Radon Mitigation in Weston, CT
Radon can be dangerous to everyone in your home. That’s why it’s important to have your home’s water tested regularly. Connecticut Basement Systems Radon Inc (CBSR) is proud to be the first Connecticut-based company to offer waterborne radon removal in the state. To ensure that your drinking water is safe, we employ two common methods: water aeration and granular activated charcoal filtration.

Radon in Your Water
Currently, there are no defined standards for the acceptable amount of radon in water. However, the EPA has suggested maximum contaminant levels (MCL) OF 300pCi/L for municipal water supplies and an alternative maximum contaminant level (AMCL) of 4,000 pCi/L for municipalities that have adopted a multimedia mitigation (MMM) program. If your water’s radon concentrations exceed 5,000 pCi/L, the state of Connecticut recommends mitigation.
Why Radon Levels Fluctuate
Radon levels in your water can fluctuate due to geologic shifts, climate conditions, water usage, and many other reasons. When water moves through the layers of the earth’s crust, it is exposed to a wide range of bedrock compositions. The longer water spends in contact with radon-bearing compositions, the more radon will dissolve into that volume of water.
CBSR has a thorough understanding of waterborne radon levels and the best methods available to mitigate these levels. We encourage you to learn about the two most common methods below.
Water aeration is a process as old as time. Natural examples include rivers cascading over waterfalls and rapids flowing across a rocky riverbed. Aeration helps to remove odor, raise pH, and improve taste.
Our aeration systems are effective at removing both waterborne radiation and other volatile organic compounds (VOCs). Depend on our system for high removal efficiencies, zero radioactive buildup, and improved water pressure.
Granular Activated Charcoal Filtration
Humans have recognized the benefits of charcoal-filtered water for centuries. CBSR uses granular activated carbon filtration (GAC) to remove both radon and VOCs by a process called ‘adsorption.’ In this process, a compound or gas adheres to the adsorbent’s (carbon’s) surface. The carbon is then activated by being superheated in an oxygen-free environment. This process creates many porous spaces on each grain of the carbon, and it is this large network of pores that give charcoal filtration its superior capabilities. As radon-contaminated water passes through the carbon bed, the carbon adsorbs radon into the pore space and out of the water.
When choosing GAC as your mitigation strategy, be sure to consider the range of radon level fluctuation in your well water. It’s important to understand the worst possible scenario, as well as your overall water quality needs. If you don’t make these considerations, excessive gamma emissions and premature filter failure can occur.
Although the EPA does not outline which system to use at certain levels, the state of Connecticut suggests that GAC can be used for waterborne radon levels up to 10,000 pCi/L. In excess of these levels, water aeration is likely the ideal technology for the job.
