It is estimated that over 3 million children in the United States suffer from lead poisoning. Lead is a toxic metal that was previously used by manufacturers in the production of faucets, fixtures, and copper pipe solder. Surprisingly, even plumbing labeled as “lead-free” may contain up to 8% lead. Despite the ban on lead in the manufacture of fixtures, pipes, and solder in 1986, it is believed that over 90% of homes in the U.S. still have lead-containing pipes. Lead leaches into your drinking water from the plumbing, solder, and fixtures within your home’s water system and water service lines. When water remains stagnant in these components, lead dissolves into your drinking water, especially if your water has low pH or is acidic. This means that the first water drawn from the faucet in the morning can contain elevated lead levels. Since lead is both colorless and tasteless when dissolved, testing is essential to detect lead in your water.
Lead in water can lead to a range of health effects, including mental and physical developmental issues in young children. Ingesting even small amounts of lead can cause permanent harm to the brain, kidneys, and hearing, particularly in children under 7 years old. Lead poisoning is not confined to children; it can also affect adults, leading to increased blood pressure, headaches, mood changes, sleep disturbances, reduced fertility in men, digestive problems, nerve disorders, and joint and muscle pain. Consuming water with high lead levels can result in mental retardation, blindness, comas, and even death. Lead-contaminated drinking water can also create complications during pregnancy and impact a baby’s normal development.
