Lead Contamination is Preventable with Epoxy Pipe Lining
The primary material for water pipes in major U.S. cities, between the late 19th and early 20th centuries, was lead. Its durability and malleability made it a very popular choice for pipe material. Eventually galvanized steel and copper would replace lead, and copper pipe would eventually become the most popular material used in home water service and distribution in mid to late 20th century construction.
Lead contamination, caused by pipe corrosion and erosion, was the major source of lead-related health problems in the years before the health hazards of ingesting lead were fully understood. Two of the most serious health problems were stillbirth and high rates of infant mortality. Part of what did and continues to makes it so serious is that, unlike many other plumbing or pipe problems, there is no way to detect it without having your water tested. On its website, the EPA offers general information about lead contamination and how to test for it.
If you have lead in your water, it?s generally because of one (or more) of these: lead-based solder which used to be the primary way to join copper pipes, a lead service line pipe linking your house to the city or town water main, and brass (or chrome-plated brass) faucets. The U.S. Congress banned the use of lead solder containing greater than 0.2% lead in 1986. It also limited the lead composition of pipes, faucets, and all other plumbing materials to 8.0%.? As a result of this legislation, ?lead-free? brass legally can contain no more than 8% lead and plumbing installed before 1986 possibly contain higher levels of lead.
In older structures, lines from the city/town water main to the home or building may be a lead pipe . Unless your piping has been upgraded in the past 40 years, it is probably galvanized pipe which does not require lead solder for joining. Faucets should be checked to see if they are brass or chrome-plated, a licensed plumber should be able to tell you if they are. CuraFlo??s website offers a brief history of lead materials in water pipes.
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.
