Can Epoxy Lining Prevent Lead Contamination from Water Pipes
Posted by: Dr. Dave Dunn in Environment, tags: EnvironmentThe 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 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 you have lead contamination from your pipes, epoxy lining can be your solution. Once installed it is a barrier to lead leaching into your drinking water. The epoxy lining prevents the metal of the pipe and the water flowing through from coming into direct contact. This prevents the chemical reaction that causes pipe corrosion. Epoxy pipe lining eliminates and prevents lead and other metals (from your pipes) leaching into the water, as well as a host of other poor water quality issues such as: water that?s red, brown, blue or yellow, zinc or iron leeching in galvanized pipes causing a metallic taste, and bacteria that causes bad tasting water or water that smells.
A relatively unknown technology, epoxy pipe lining is not a new technology, –in fact it?s well proven. The U.S. Army Corps of Engineers and U.S. Navy have both ested and approved the use of epoxy pipe lining to prevent contaminants, including lead, from leaching into drinking water. Their reports are published and links to them can be found at curaflo.com/CuraFlo/ResourceCenter. The epoxy used by CuraFlo in epoxy pipe lining, CuraPoxy?, is certified to meet the U.S.
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.
