Radon aeration treatment unit installed for a private well near Sioux Falls SD

Sioux Falls city water is surface and treated groundwater and is not a meaningful radon source. Step outside the city limits, though, and private wells are everywhere: acreages around Hartford, Colton, Valley Springs, Worthing and out along the Big Sioux. Radon dissolved in well water comes out of solution the moment the water is agitated, which means every shower, every dishwasher cycle, every toilet flush releases it into the air of the room.

The tell

You have a working mitigation system, the manometer looks right, and the air test still comes back elevated. Or the readings spike in the morning and evening and settle overnight. Both point away from the soil and toward the plumbing. A water sample is cheap relative to chasing this the wrong way for a year, and it is the first thing to rule in or out on a rural property.

Aeration or carbon, and how to choose

Aeration systems spray or bubble the water in a sealed tank and vent the released gas outdoors, and they handle high concentrations well without accumulating anything. Granular activated carbon filters the water through a carbon bed and works well at lower concentrations, but carbon adsorbs the radioactivity rather than releasing it, so the media becomes a low-level radioactive item over time and has to be sited and eventually disposed of accordingly. High levels get aeration. Modest levels on a small household can go either way. Anybody selling you carbon for a very high reading has not thought about where that radiation goes.

Order of operations

Air first, water second, and treat the soil gas before the water in almost every case, because the soil pathway is usually the larger contributor even on a well. Fix the sub-slab system, retest the air, and if the number is still stubborn, sample the water. Doing it in that order saves a lot of people the cost of a treatment system they did not need.

Is radon in water dangerous to drink?

The primary risk is inhalation of the gas released into the air during showering and other household use, not ingestion, though ingestion carries a smaller separate risk. This is why water radon shows up as an air quality problem in the bathroom rather than as a drinking water complaint.

Does Sioux Falls city water have radon?

Municipal supplies are not a significant radon source, and treatment and distribution allow dissolved gas to escape long before it reaches a tap. Radon in water is a private well issue, which around here means the acreages rather than the city.

How much does radon water treatment cost?

Considerably more than an air system, generally several thousand dollars for aeration, because it is a tank, a blower, a vent and a repressurization pump rather than a fan and some pipe. Test the water before assuming you need it.
