You need to know your aquifer and the state of the well casing. (these are awfully good things to know for all sorts of other purposes, not just in the remote chance of a nuclear incident).k0xxx said:I have a underground house with a inside drilled well.I need to know how long that water source will be good.This plant has been here since 1974.I don't fish anywhere near it but I still wonder how it could harm the water.I haven't research it but I wonder is there someway to "clean" the water of radiation?
Some deep aquifers have a recharge time of tens of thousands of years or more, thus as long as your well casing is intact you would expect in a perfect world for the water to be 100% fine for way longer than you care about
In reality of course you have to remember that wells go *both ways* and that if someone *else's* well into that aquifer should get contaminated -- by E coli, by a leaky fuel oil tank, by chemicals, by a buncha radioactive particle input -- then what matters is the transit time of the aquifer water from their well to yours. It is hard to envision too many circumstances where *radioactive* contamination could happen this way -- yeah, I can make up baroque one-off scenarios, but I don't see anything particularly *likely*. However there are certainly a number of cases where this demonstrably *does* happen with OTHER kinds of contamination, e,g. bacterial or chemical, typically because folks have been unwise around poorly-sealed or poorly-lined wells. So it IS something to have on your mental radar, IMHO.
Then there are other wells or other aquifers. Some wells are really shallow and thus they both have short recharge times (the time it takes for surface water to infiltrate into the aquifer water) AND have a lot more locations where surface water CAN get into the aquifer. This is particularly true where you're talking about shallow dug unlined wells, or places like some of KY where you may actually be drawing water not so much from an aquifer but from an underground stream that may not have been underground for *all* that far.
If your well often tests high for bacteria (it is smart to have it checked at least yearly, a lot of places the municipality/state/province will do it for free) then it is probably smart to assume that it is pretty vulnerable to contamination by other things too. Although if your well *never* tests high in bacteria I would not necessarily assume nothing can get to it.
In terms of removing radioactive contamination from water (well or other), in principle excellent filtration and distillation-or-RO will do it. In reality there are enough ways for those things to be done not quite right that I would not be doin' em unless I had run out of bottled water and there was no realistic possibility of any other safe water source. HOWEVER note that if this should happen, either it is because of some very, very, very, very, very, very odd circumstances that have contaminated ONLY groundwater and thus there are likely to be official distributions of safe water and/or effective distillation systems to those effected; or minor radioactivity in groundwater is quite frankly going to be THE LEAST of your problems
