The Cost and Benefits of Replacing Lead Pipes in the US

The US Environmental Protection Agency has proposed a rule to replace millions of lead service pipes within the next 10 years, in line with the Biden administration's goal of removing all lead pipes. Lead exposure is particularly dangerous for children, as it can cause damage to the brain and nervous system, leading to lower IQ, learning difficulties, and impaired growth. Symptoms of lead poisoning may include abdominal pain, headaches, and developmental delays. Lead levels can be diagnosed through blood testing, and treatment options include flushing out the lead and reducing lead in the bloodstream. While removing lead pipes will reduce the number of children exposed, it is important to also address other sources of lead exposure, such as lead paint and soil contamination.
