The Danger Of Lead In Water

Does A Carbon Filter Remove Lead From Water

As we turn on our taps, we expect water that is free from harmful substances. However, it’s not always the case as dwindling infrastructure, corrosion, and plumbing issues sometimes contaminate our water with lead – a toxic substance. This article will explore the dangers of lead in water, the history of lead in household plumbing and how it gets into our drinking water.

Lead’S Harmful Effects On Human Health

Lead contamination poses a severe health risk to humans, children being the most affected. Exposure to lead may result in the following health issues:

  • Damage to the brain, kidneys, and nervous system
  • Learning and developmental disabilities in children
  • Growth retardation in children
  • Anemia
  • High blood pressure
  • Infertility in men and women

In the worst cases, lead poisoning may lead to coma or even death. Therefore, it’s necessary to take precautionary measures and seek medical attention if exposed to lead.

The History And Evolution Of Lead In Household Plumbing

Believe it or not, lead plumbing has roots dating back to the roman empire. The first evidence of lead plumbing dates back to 3000 bce, where lead pipes were used to transport water. It’s no secret that lead was an essential material in early plumbing, but it wasn’t until the 1920s that its usage was widespread in the united states.

In the us, the prevalent use of lead pipes was during the post-world war ii housing boom. Due to the affordability and ease of installation of lead pipes, they found widespread use in plumbing systems. As demand grew, so did innovations in plumbing materials, and lead’s usage in plumbing declined, culminating in the 1986 ban on lead pipes and plumbing materials through the safe drinking water act (sdwa).

How Lead Gets Into Drinking Water

Lead generally gets into drinking water through corroded plumbing fixtures and fittings, solder joints, and service lines. It leaches into the water as it passes through these fixtures and fittings, especially in stagnant water which has been sitting in pipes for a while.

It’s important to note that lead contamination rarely occurs before the water enters your home through the municipal water system, but rather it’s after the water has entered a household’s plumbing system through pipes.

Carbon filters are popular in-home filtration systems, and many people believe that they remove lead from drinking water. While it’s true, they do remove some of the lead in the water, it isn’t the most effective method. An activated carbon filter can remove chlorine, lead particles, and other volatile organic compounds but doesn’t remove the dissolved lead ions entirely.

To effectively remove dissolved lead ions from drinking water, reverse osmosis or ion exchange filtration systems are most effective.

Lead contamination of drinking water presents a severe health risk. It’s therefore important to take measures to ensure that we have safe drinking water. Although carbon filters do remove some lead from drinking water, a more effective system that removes dissolved lead ions is necessary for optimal water safety.

By understanding how lead gets into water, its history, and the harmful effects it poses to human health, we can take necessary precautions to ensure that we have safe drinking water.
