View Full Version : Bonne Terre and the Lead
Plane Trouble January 18th, 2012, 12:20 PM This may be just a really dumb question to ask but, I was considering going on a little diving excursion to Bonne Terre. However one thing always comes to mind when thinking of the place... Its a Lead mine... and Lead "no be good for you"... Does anyone know how this works there? I'd assume the lead concentrations in the water are probably not at dangerous levels, but how? Fish in a Barrel January 18th, 2012, 05:11 PM Lead doesn't come out of the mine in pure form. It's chemically bonded in various mineral deposits. The minerals that contain lead aren't water soluble. The water is non-toxic and drunk by the locals from wells all over that area.

Have you seen the locals??? J/K - Couldn't resist... jimmy71 April 17th, 2012, 09:12 AM Have you seen the locals??? J/K - Couldn't resist... I was thinking the EXACT same thing!!!!! NetDoc April 17th, 2012, 09:39 AM The lead has to be extracted from Galena ore: it is not free. They do continual checks of water purity and lead has never been detected in the analysis. tyesai April 19th, 2012, 12:52 AM I was wondering the same thing after coming across their website while looking for "different" dives. RIteen April 20th, 2012, 08:25 PM So long as you don't chew the window sills while you're down there you will be fine. :P The amount that leaches yearly is most likely negligible... and even then you would probably have to become a permanent buoy in the mine in order to be affected... Max Speed April 21st, 2012, 02:02 PM The nearby off road riding area is plastered with warning signs about the lead danger from the mine debris and offers rinsing stations to clean the lead containing dust from your vehicles and gear. You can obtain a map of the area from the rangers which indicates the areas of greatest danger. Maybe the mine is cleaner? ---------- Post added April 21st, 2012 at 01:04 PM ---------- On the other hand.....have you ever used soft weights? And looked at the little cloud of lead oxide which streams off the bag when you enter the water? NetDoc April 21st, 2012, 02:16 PM Maybe the mine is cleaner? They didn't smelt the lead inside the mine. Think about it. Wookie April 21st, 2012, 02:20 PM Really, lead is an inhalation hazard in the form of Load Oxide (PbO2) and as an ingestion hazard in pretty much any form. Don't inhale or drink the water and you'll be fine. You can drink the water if you want, the lead would rather stay bonded with the sulpher (in the form of sulfide) than to become free and get into the water. Lead is only truly hazardous when it isn't bonded with anything else. Then it bonds with you. Hatul April 21st, 2012, 03:58 PM Anyone have a link to the analysis of the water in the mine? NetDoc April 21st, 2012, 04:50 PM I think it's funny that the Pb symbol for lead comes from its Latin name, plumbumb. Now we know how plumbing got its name!

One theory for the downfall of the Roman Empire is the slow poisoning caused by their lead water pipes.
