Hi Nick
The lead is in the solder at the tip of the socket and a tap on the 
threaded base of the tree lights. It is in the brass fixtures and 
fittings  to reduce the melt surface tension so it fills the mold 
better. I have worked lead pipe  in Vermont  that was in place for many 
decades. It gets a nice thin scale buildup and the water tests clean. If 
you have soft water the lead will leach out of the pipe and the brass, 
if your water is hard, it probably won't. At the pump outlet, the 
turbulence will tend to clean the fittings, and likely leach the lead.

To learn more about minerals dissolved in water there are several 
articles at http://www.zetacorp.com/science.shtml

Greetings Wrenches,
 Just curious how concerned other wrenches are with lead in electrical 
tape,brass valves, fittings and even LED Christmas lights. Not sure if 
our stickers make it out of California but I've been noticing many 
products with the Prop 65 stickers and wonder why the lead is even in 
the product to begin with. It's fairly easy enough to find lead free 
electrical tape but sometimes find it difficult to find a brass thread 
to barb fitting for submersible pumps without lead in it. Am I 
over-reacting with my concern not to place a fitting known to have lead 
as the first thing out of the pump? Does the lead leach out from the 
brass and at how many PPM is it deemed safe? I've found some references 
online about it but not really anything explaining why it's present to 
begin with. I can understand it to be naturally occurring to some extent 
in brass somehow but how the hell does it make it into electrical tape 
and Xmas light wires?

Thanks for any insight,

Nick A Lucchese
