The Biscayne Aquifer sits less than 25 feet below ground throughout most of Miami-Dade County, making it one of the shallowest major municipal water sources in the United States. This limestone formation naturally dissolves into groundwater, creating hardness levels between 180 and 250 parts per million. Coastal neighborhoods from South Beach through Coconut Grove face additional challenges when storm surge or king tides push saltwater into the aquifer temporarily, introducing sodium chloride that water softeners cannot remove. Homes within two miles of Biscayne Bay benefit from reverse osmosis drinking water systems in addition to whole house softening for comprehensive protection against both hardness minerals and periodic salt intrusion.
Miami-Dade Water and Sewer Department treats aquifer water with chlorine and occasionally chloramine to meet federal Safe Drinking Water Act standards, adding chemicals that accelerate corrosion of copper pipes and fixtures while creating taste and odor issues many residents find objectionable. Local water treatment expertise means understanding which neighborhoods receive water from which treatment plants and adjusting filtration accordingly. We work throughout Miami's distinct communities, from the historic homes of Coral Gables with their original plumbing to new construction in Doral, and we understand how building age, pipe materials, and water source location affect treatment system design.
