What is the reason behind water utilities having to replace Lead, Copper, and Galvanized Lines?

Health Risks Associated with these Materials.
Water Utilities are required to replace lead, copper, and galvanized pipes due to the health risks associated with these materials. Lead pipes can lead to drinking water, posing serious health risks, especially to children. Copper and galvanized pipes can corrode and release harmful substances into the water supply. The EPA's Lead and Copper Rule Improvements mandate the replacement of all lead service lines within ten years to ensure public health and safety. This regulation is part of a broader effort to address the widespread use of these materials in drinking water systems and to protect vulnerable populations from potential health impacts.
