Lead is not detectable in the DWS system. It comes from lead-based solder, lead service lines, brass faucets, and bronze components. It is mainly found in older homes (pre-1986) where lead-based solder was used, or in homes in which high lead brass fixtures were used in plumbing systems.
New fixtures can also leach lead. Regardless of the age of your home, you should get your water tested at the DWS Laboratory to find out for sure if your plumbing is leaching lead. The testing is free for Upcountry customers. Call (808) 270-7550 for more information. More information on lead and copper
