Radon in Well Water in Brandon, SD
Call (605) 210-7667 Brandon is 9 miles from Sioux Falls. You hear back from a person, not an autoresponder, within one business day. Call before 3pm on a weekday and it is usually the same afternoon.
Brandon itself is on municipal water and this is not a Brandon-proper issue. The acreages between Brandon and the Minnesota line, and the properties along the Split Rock Creek valley outside the city, are a different matter and are on private wells.
What we see in Brandon
Where the valley has cut toward the quartzite shelf, groundwater is moving through fractured rock rather than deep till, and dissolved radon concentrations tend to follow. If you are inside the city limits, skip this and read the mitigation page instead.
Practical notes for Brandon homeowners
Aeration for a rural household runs several thousand dollars, considerably more than an air system, because it is a tank, a blower, a vent and a repressurisation pump rather than a fan and some pipe. Test the water before assuming you need it.
Radon in Well Water in Brandon: the technical part
This applies to the acreages, not to Brandon proper. Inside the city you are on municipal water and there is no water radon question at all. Along the Split Rock Creek valley and out toward the Minnesota line, private wells drawing from fractured quartzite where the valley has cut toward bedrock are a genuinely different proposition from a town supply.
What the job looks like in Brandon
Air test first with the hourly trace, soil system next, retest, and a water sample only if the number stays high. On the acreages we sample before treatment at the tap nearest the tank. Where a system is justified, aeration sizing follows household peak demand and the vent terminates outside above the roofline.
The ground under Brandon
Brandon sits on glacial till above the Sioux Quartzite shelf, with Split Rock Creek having cut down through it right in the middle of town. Where the till is thin over fractured quartzite, soil gas has a short trip to the underside of a slab.
