Ye ole well water stank

[Egon]

Yeah...but not much. Btw, where does lead come from to begin with?

But how little is too much?

 

[stuckmotor]

Is it the bullet or the explosion that clears the screen?

If my well water had excess lead, I'd either drill a new well or install a treatment system. Lead in its natural state is usually as a sulfide (galena), sulfate (anglesite) or carbonate (cerrusite) which are all typically stable underground. When the system is changed by introducing oxygen and creating acidic conditions as by mining, they tend to become unstable and leach into ground water or come out as acid mine drainage.

Arsenic, radon, natural gas and petroleum are also natural products from the earth - doesn't mean I want them in my drinking water; and I won't be intentionally introducing them into my well.

The safe drinking water limit for lead is 15 micrograms per liter (parts per billion) or 0.0000000015.
That's a pretty small number as in your "...not much". But you do what you want.

Has to be the bullet...sand points are used 25' or so down and the "shooting" is through a pretty big pipe. No way I can see where the concussion alone would clear the sediment with something as tiny as a .22 round. As for lead poisoning, if that little piece of lead perhaps eroding over a long period of time (diluted with all the water that will bring it up to your faucet, most of which will end up in your septic system with dish washing etc.), I believe non-lead .22 ammo is available.

I'm not drinking it. Just watering trees. I don't really like the idea of drinking groundwater next to a grain field.

Now, I'm really perplexed. When the lab technicians want to catch a bullet on crime shows, they fire it into what seems like only a few feet of water. I'd have guessed that a bullet would have lost all of it's wallop by the time it got to the sand point.

Its an enclosed space so the energy cant dissipate outward like it can in a more open container.

Does the shock of the bullet striking the water dislodge the iron or does the bullet hitting the screen clear it or punch a hole in it?

Where does the energy go?

Ok...I get the question now...you can search for "sand point". I think the sediment usually builds up where not a lot of water passes through it (summer cabins etc.). The bullet impact dislodges that. You do not want to punch a hole the screen (in Wisconsin you would have to pull the point and depending on where you are, you may not be able to replace it and would be forced to go to a drilled well). Thus the .22 seems to be the weapon of choice and "aim" is critical...maybe a few pops will be required and you would certainly want to keep an outside faucet running to clear all the junk you have just dislodged. Safety glasses required!!!
