During the 19th and early 20th century lead was widely used in major U.S. cities for water pipes because of its durability and malleability. Lead pipes were eventually superseded by galvanized steel and copper, and copper pipe became the predominant material selected for domestic water service and distribution in post-World War II residential construction.
Pipe corrosion and erosion-caused lead contamination, was the top source of lead-related health issues before the hazards of ingesting lead were realized. Stillbirth and high infant mortality were two of the worst effects of lead ingestion. Many other plumbing or pipe problems are easy to detect by seeing or listening, but without specifically testing for it, there is no way to detect lead in your water. The EPA offers general information about lead contamination and how to test for it on its website.
If you have lead in your water, it?s generally because of lead-based solder which was the primary material to join copper pipes together, a service line pipe from your house to the city or town water main made out of lead, and brass or chrome-plated brass faucets. In 1986, Congress put and end to the use of lead solder with over 0.2% lead in it. The lead in faucets, pipes and every other plumbing material was not allowed to exceed 8.0%.? ?Lead-free? brass legally can can?t have than 8% lead in it and plumbing systems installed prior to the 1986 legislation can possibly contain higher levels of lead.
Water lines from the city or town water main to a home or building?s water system may be a lead pipe in older structures. If you or a previous owner of the structure had your plumbing system upgraded since 1960, it?s probably composed of galvanized pipe. Galvanized pipe doesn?t need lead solder to be joined. Faucets need to be checked for brass or chrome-plating, you?re the original manufacturer, a local hardware store, or a licensed plumber should be able to tell you if yours contain either.
If your pipes are the source, epoxy lining will prevent lead leaching into your drinking water. Because the epoxy lining creates a barrier between the metal pipe and the water coming in contact with it, it stops the chemical reaction that causes corrosion. It eliminates and prevents from reoccurring, leaching of lead and other metals into the water, as well as a host of other poor water quality issues such as: discolored water (red, brown, blue or yellow), metallic taste (caused by zinc or iron leeching in galvanized pipes), and water odor or bad taste (caused by bacteria).
The U.S. Army Corps of Engineers (http://www.wbdg.org/ccb/ARMYCOE/PWTB/pwtb_420_49_35.pdf) and the U.S. Navy (http://stinet.dtic.mil/cgi-bin/GetTRDoc?AD=ADA327758&Location=U2&doc=GetTRDoc.pdf) have documented their use of epoxy pipe lining to prevent lead and other contaminants from leaching into drinking water.
government?s highest stadard for safe drinking water: ANSI/NSF Standard 61. ANSI/NSF Standard 61 certification means CuraPoxy is certified for safe use in drinking water pipes carrying water up to 180? Fahrenheit or 82.2? Celsius. The proprietary epoxy and epoxy pipe lining process CuraFlo uses will protect you from lead and other metals in your pipes that may be leaching into your water now or might in the future, by creating a safe barrier between them and your water.
