Radon Mitigation System

[ReefDreamz]

I have a radon mitigation bubbler system installed in my home which removes radon gas from the water. This system was installed by a previous owner of the house. There is a run of PEX plumbing in my basement whose sole purpose is supplying water to a hose bib on the exterior of the house. The plumbing that feeds this hose bib does not go through the radon bubbler, it branches off the main plumbing from my well pump before the radon bubbler. This plumbing is in a very convenient location in my basement for me to tap into to feed my RO/DI unit for my tank. Would it be dangerous for me or my aquarium inhabitants if I plumbed the RO/DI unit into the plumbing that comes directly from the well and doesn't pass through the radon bubbler?

I think you would need to have a radon expert provide some guidance here and possibly some additional testing to understand the levels in the water supply both before and after the bubbler. Since radon is a gas and the bubbler removes the gas from the water then connecting an RO/DI unit to water not treated for radon removal might be a hazard since it might allow additional radon gas into your home via the RO/DI filter outputs.
