Why is Lead No Longer Used in Plumbing?
For many years, lead has been used in plumbing and other products. In the early 1900s, Philadelphia had plumbing codes requiring lead piping. In 1938, the LIA worked to get these regulations changed in Pennsylvania. The association helped set up classes for plumbing apprentices and journeymen teaching them how to use lead pipes. While they recognized that lead was dangerous, they didn’t agree with the scientists who promoted this view. why is lead no longer used in plumbing
Although lead has been banned from plumbing since 1986, lead pipes are still carrying water in millions of homes. While these pipes are buried underground, most Americans are unaware of them. However, according to APM Reports, the aging conduits continue to put tens of millions of people at risk for lead exposure. However, the government’s efforts to limit exposure to lead have failed to stop leakage and the spread of lead.
The removal of lead pipes caused some concern, but it wasn’t an immediate danger. Lead pipes didn’t break down easily, and their lifespan was longer. This is partly because lead is not particularly reactive or soluble. Moreover, lead pipes lasted longer than their iron counterparts. But with the rise of chlorine and chloramines, lead in plumbing was deemed dangerous to human health. This change took 11 years to complete and cost the city $15.5 million.
As part of the National Plumbing Code, lead is no longer used in plumbing products. Although most cities and states now have plumbing codes that strictly ban the use of lead, the majority of older pipes still contain lead. However, it is possible that some older plumbing in private buildings are still made of lead. If this is the case, it is important to note that the plumbing of older homes might have been made using lead before the law was passed in 1986.
As part of a cost-benefit analysis, the government is providing unprecedented support for states to replace lead service lines. The bill contains $15 billion in funding for lead pipe replacement, whittled down from President Biden’s original proposal of $45 billion. The funding provided by the bill is the largest federal investment in replacing lead pipes. Research reveals substantial public health and economic benefits. Consequently, it is crucial that lead pipes be replaced before the bipartisan infrastructure bill is finalized.
The EPA knows that the current testing method for lead pipes doesn’t adequately measure the amount of lead that is released in water. Water experts at the EPA had suggested changes to the Lead and Copper Rule that would have forced utilities to test a wider range of lead levels in their water. The EPA rejected these changes, ceding the process to an ad hoc advisory board with heavy representation from water utilities. The agency’s final rule is based on scientific research and recommendations, which aren’t necessarily based on human health.
Water utilities and water utility companies have not been convinced of the need to replace their service lines. While EPA and other agencies have advocated replacing all lead pipes, the utilities have argued that it is too costly and will lead to more headaches. They argue that a portion of a service line that runs under private property is a homeowner’s responsibility. The EPA attempted to reach a compromise by issuing the Lead and Copper Rule in 1991. The new rule will be revised this summer.
