Madison’s water source is an aquifer in deep underground sandstone formations. The aquifer is recharged from precipitation naturally filtered by its downward progress from the surface. City wells tap the aquifer, and the water is pumped through our distribution system after limited and closely monitored additions of chlorine and fluoride, assuring a reliably safe, high-quality community water supply. Hydrologic studies have shown that the aquifer supports sufficient quantities of water to meet the city’s projected water demands indefinitely with appropriate management and reasonable conservation measures, including groundwater protection measures.
