University Park Water Hardness & Quality Report (2026)

Miami-Dade Water and Sewer Department provides drinking water to University Park, situated in the southwest Miami corridor of Miami-Dade County, Florida. The utility sources its supply from the Biscayne Aquifer, the primary groundwater source underlying this region of south Florida. Water is drawn from wells tapping the Biscayne Aquifer and distributed to residents throughout the Miami-Dade County service area. Very limited softening is applied before distribution, meaning the naturally high mineral content of the Biscayne Aquifer is largely preserved in the delivered supply, resulting in very hard water throughout Miami-Dade County.

University Park's water supply is drawn from the Biscayne Aquifer, an extremely calcareous carbonate aquifer underlying south Florida and Miami-Dade County. The aquifer is hosted within the Pleistocene Miami Limestone, a highly calcareous formation characteristic of the region. This carbonate geology saturates groundwater with calcium and magnesium as it moves through the limestone, producing one of the most mineral-rich aquifer systems in south Florida. The extremely calcareous nature of the Biscayne Aquifer combined with very limited softening at treatment results in very hard water throughout the service area.

Very hard water from the Biscayne Aquifer causes significant scale buildup in pipes, water heaters, dishwashers, faucets, and household appliances throughout Miami-Dade County. Because very limited softening is applied by Miami-Dade Water and Sewer Department, the high calcium and magnesium levels persist to the tap. Residents experience white mineral deposits on fixtures, reduced soap lathering, and shortened appliance lifespans. A water softener is strongly recommended for households in University Park to protect plumbing and appliances from this very hard, carbonate-rich supply.
