Hialeah – Florida – Water Quality Report 2025: PFAS Testing, Infrastructure Concerns & Safety across your city
The City of Hialeah Department of Public Works provides comprehensive water services to over 230,000 residents across a 23 square-mile area in Miami-Dade County, including portions of unincorporated areas. Established as a municipal utility with emergency interconnects to Hialeah Gardens and Miami-Dade County, the system purchases most of its water from Miami-Dade County while operating its own Reverse Osmosis Water Treatment Plant that delivers 7.5 million gallons daily to northwestern Hialeah residents.
Hialeah sources its drinking water primarily from the Biscayne Aquifer, a reliable underground geological formation that has supplied freshwater since the early 1920s. The southeastern area receives water from the John E. Preston Water Treatment Plant owned by Miami-Dade County, while the City of Hialeah-owned Reverse Osmosis Water Treatment Plant draws from the deeper Floridan Aquifer for consistently high-quality source water. Residents consume approximately 24 million gallons of water daily, with the utility maintaining compliance with all federal and state quality standards while investing in capital improvements and water conservation initiatives.

Frequently Asked Questions
Is Hialeah’s tap water safe to drink?
Yes, Hialeah’s tap water meets all federal and state drinking water standards. The city receives most of its water from Miami-Dade County, which undergoes comprehensive treatment including filtration and disinfection. The Hialeah Reverse Osmosis plant provides additional high-quality water through advanced membrane treatment.
Miami-Dade County maintains over 8,500 miles of water lines and conducts extensive testing to ensure water quality surpasses federal, state, and local standards. Recent EPA assessments confirm the water utility remains in compliance with all health-based drinking water standards, demonstrating the system’s commitment to providing safe drinking water to residents.
Why does my water sometimes taste or smell different?
Taste variations can occur due to several factors:
1. Disinfection method: Miami-Dade County water uses chloramine disinfection, which can cause a different taste compared to chlorine. This taste won’t fade if water is left in the refrigerator overnight
2. Source variation: Water from the Hialeah RO plant (chlorine disinfection) may taste different from Miami-Dade County water (chloramine disinfection)
3. Natural organic matter: Water from certain areas of the Biscayne Aquifer may contain natural organic material that can affect color and taste, though it poses no health risk
If taste or odor issues persist, contact Hialeah City Hall at (305) 883-5800 for assistance. Running water for a few minutes after periods of non-use can sometimes help improve taste and odor.
Does Hialeah have lead in its water system?
Hialeah’s water system maintains compliance with federal lead and copper regulations:
• Testing results: Recent analysis shows a 90th percentile lead concentration of 2.1 ppb, well below the federal action level of 15 ppb
• Service lines: The distribution system primarily uses non-lead materials, with comprehensive monitoring throughout the service area
• Treatment measures: Water treatment includes corrosion control to prevent lead leaching from older plumbing components
• Home testing: Residents concerned about lead can contact water quality testing services, especially for homes built before 1986
While the EPA recognizes no safe level of lead, Hialeah’s levels remain well within compliance and the utility continues monitoring and treatment optimization.
Are there water restrictions in Hialeah?
Miami-Dade County maintains year-round water conservation measures:
Standard Conservation Rules:
• No lawn watering between 10 a.m. and 4 p.m. daily to minimize evaporation
• Efficient irrigation practices encouraged to reduce water waste
• Leak detection and repair programs to maintain system efficiency
Drought Response:
During severe drought conditions, additional restrictions may be implemented including:
• Further limitations on outdoor watering
• Restrictions on vehicle washing and pool filling
Current water use guidelines and any emergency restrictions are available through Miami-Dade County Water and Sewer Department at 305-274-9272 or miamidade.gov/water.
Contaminants of Concern
Disinfection Byproducts
Source: Formed when chlorine or chloramine disinfectants react with naturally occurring organic matter in source water; levels may vary seasonally based on source water conditions
Health Effects: Long-term exposure to elevated levels of trihalomethanes (TTHMs) may increase cancer risk and potentially affect pregnancy outcomes
Current Levels: Monitored regularly throughout the distribution system with bromodichloromethane detected within regulatory limits EPA Limits: 80 ppb for total trihalomethanes and 60 ppb for haloacetic acids
PFAS Compounds
Source: Per- and polyfluoroalkyl substances including 6:2 Fluorotelomer Sulfonic Acid detected in water testing, originating from industrial processes and consumer products
Health Effects: Research indicates potential impacts on immune system, liver function, cholesterol levels, and possible links to certain cancers and developmental effects
Current Status: Detected at low levels with monitoring ongoing; EPA finalized new PFAS regulations in 2024 EPA Action: New maximum contaminant levels established for specific PFAS compounds
