HIALEAH DRINKING WATER

FLORIDA DRINKING WATER Hialeah, Florida drinking water is supplied primarily by the City of Hialeah Department of Public Works, which serves ~230,000–238,000 residents.

The city purchases most of its water from Miami-Dade Water and Sewer Department (WASD) and produces some itself via a reverse osmosis (RO) plant. Official reports confirm it meets all federal EPA and Florida state standards, with no Maximum Contaminant Level (MCL) violations in recent data.

FLORIDA DRINKING WATER Water Sources and Treatment

  • Primary sources: Groundwater from the Biscayne Aquifer (shallow, freshwater) for most supply. The city’s Reverse Osmosis Water Treatment Plant (ROWTP, jointly owned/operated with Miami-Dade) draws brackish water from the deeper Upper Floridan Aquifer (~1,200–1,400 ft deep).
  • Average daily use: ~24 million gallons per day (MGD).
  • Treatment facilities:
  • City purchases bulk water from Miami-Dade’s Hialeah and John E. Preston Water Treatment Plants (Biscayne Aquifer source). Treatment includes lime softening (to reduce hardness), filtration, fluoridation, disinfection (chloramines or chlorine), and air stripping (to remove volatile organic compounds/VOCs). The Preston plant uses enhanced softening.
  • Hialeah RO Plant: Initial capacity 7.5–10 MGD (expandable; portions shared with county NW service area). Brackish water is pretreated (acid, antiscalant, cartridge filtration), pressurized through RO membranes (removes salts, sediments, ions, bacteria), then post-treated (pH adjustment, degasification for H₂S, remineralization with lime/CO₂, disinfection, fluoridation). Operated under a joint venture (historically involving AECOM/Inima).
  • Southeastern Hialeah often receives water via the Preston plant; northwestern areas via the RO plant. Emergency interconnections exist with Hialeah Gardens and Miami-Dade.

The city invests in Capital Improvement Programs for infrastructure reliability and conservation.

FLORIDA DRINKING WATER Drinking Water Quality and Test Results (2024–2025 Data)

The City of Hialeah’s 2025 Consumer Confidence Report (CCR) (covering 2024 testing) states the water meets or exceeds all standards. Key results from the city’s CCR (comparing Miami-Dade WASD supply, Hialeah RO, and distribution):

Microbiological: Total coliform = 0 (no detections; Treatment Technique standard).

Disinfectants & Byproducts (running annual averages/ranges):

  • Chloramines: ~2.7 ppm (0.1–4.0); MRDL = 4 ppm.
  • Chlorine (RO): ~3.1 ppm.
  • Total Trihalomethanes (TTHMs): WASD 51 ppb (10–69); Distribution ~18 ppb (0.39–22); MCL = 80 ppb.
  • Haloacetic Acids (HAA5): WASD 44 ppb (3–81); Distribution ~40 ppb (0.98–49.63); MCL = 60 ppb.

Inorganics (examples; all well below MCLs):

  • Arsenic: ~2 ppb (WASD); ND or very low (RO); MCL = 10 ppb.
  • Barium: ~0.008 ppm; MCL = 2 ppm.
  • Chromium: ~2 ppb; MCL = 100 ppb.
  • Fluoride: ~0.55–1 ppm; MCL = 4 ppm (added for dental health).
  • Nitrate (as N): ~0.3 ppm; MCL = 10 ppm.
  • Sodium: ~33–51 ppm (no MCL; secondary standard 160 ppm).
  • Lead (point of entry): Very low (e.g., 0.003 U ppb).
  • Lead (at tap, 90th percentile): ~1.48–3.2 ppb (1–1.26% of homes exceeded Action Level of 15 ppb in sampling); Copper 90th percentile ~0.07–0.09 ppm (0% exceeded AL of 1.3 ppm). Corrosion from household plumbing is the main source.

Radioactive: Alpha emitters ~1 pCi/L; Combined radium low/ND; Uranium low; all below MCLs. Radon detected in some source water (naturally occurring; no federal MCL).

PFAS (unregulated/monitored under UCMR): Detected at low levels in some samples (e.g., PFOS up to ~10–31 ppt in certain data; PFOA lower). Newer EPA MCLs (4 ppt for PFOA/PFOS) apply going forward; city RO and treatment keep levels low/ND in finished water in many cases. Hazard Index and other PFAS monitored.

Other: Hardness is typically high/very hard (reports cite ~300–400+ ppm or 11–22+ gpg in area data), leading to scale. No Cryptosporidium/Giardia detections historically in source water.

Third-party summaries (EWG-style, TapWaterData, etc.) note 0–3 contaminants above stricter health guidelines (e.g., some disinfection byproducts, PFAS traces, hardness-related), but 0 EPA MCL violations. Scores often ~70/100 (fair/good). Water is safe per legal standards; some recommend home filtration for taste, hardness, DBPs, or PFAS.

FLORIDA DRINKING WATER Drinking Water Challenges and Complaints

  • Aging infrastructure: Older pipes (1960s era in parts of east Hialeah) cause leaks, main breaks, discolored/turbid water after repairs or floods, and higher costs. System is overloaded in places.
  • High bills: Residents often pay among the higher rates in Miami-Dade (~30% more than some peers). Factors include bulk purchase costs from county, franchise fees (recently suspended/reduced), leaks, and meter accuracy disputes. Recent mayoral actions include audits, smart meter pilots (free), and bill relief efforts amid complaints of high/erroneous charges. Hospitals have owed large unpaid bills.
  • Taste/odor/appearance: Chloramine residual, hardness scale, occasional turbidity after pressure events. Some resident complaints of dirty/yellow water (localized, often post-repair).
  • Financial/operational: City has faced county lawsuits over ~$18M unpaid bulk water/sewer bills (disputed over meters); ongoing debt and rate pressures. Capital improvements funded partly by ARPA and bonds.
  • Source pressures: Biscayne Aquifer is heavily used regionally (saltwater intrusion risk, septic/nutrient pollution). RO plant diversifies supply. PFAS and emerging contaminants under monitoring.
  • No widespread health-based violations, but administrative/monitoring issues have occurred historically.

FLORIDA DRINKING WATER Boil Water Notices Frequency

Notices are precautionary (not mandatory contamination confirmations) and common after water main breaks, repairs, pressure loss, or flooding. They typically last 24–48+ hours until bacteriological testing clears.

  • Frequency: Multiple per year (dozens of localized advisories/rescissions visible in city Alert Center archives for 2021–2026). Examples: June 2024 (flooding, specific NW areas); post-Irma 2017; contractor main strikes; routine repairs. Not constant citywide, but frequent enough that residents should monitor alerts. Rescinded promptly after negative tests.
  • City encourages flushing taps after pressure events and following boil instructions (1-minute rolling boil).

FLORIDA DRINKING WATER Projects Requiring Well/Septic Destruction and Hookup Costs

Hialeah is largely urban/sewered, but Miami-Dade County (including areas near/in Hialeah influence) has a major Connect 2 Protect septic-to-sewer program (~120,000 septic systems countywide; ~9,000–13,500 vulnerable to failure from groundwater rise). Goals: Reduce nutrient pollution to Biscayne Aquifer/Bay, improve health/resilience. Includes lateral expansions, grants, and infrastructure buildout (hundreds of millions invested; multi-year). Some commercial corridors and residential areas prioritized. Hialeah-specific projects may tie into city CIP or county efforts near borders.

Well abandonment (if converting private wells): Florida DOH/DEP rules require proper decommissioning (pump, fill/crush, seal, permit/inspection). Costs typically $500–$3,000+ (higher for removal).

Septic-to-sewer conversion costs (Miami-Dade/Hialeah area, 2025–2026 estimates; highly site-specific):

  • Typical total: $5,000–$25,000 (most $10,000–$20,000). Lower if main is close/abutting; higher with long laterals, pumps, rock, driveway restoration.
  • Breakdown: Municipal connection/tap/impact fee (~$3,000–$8,000+ residential; city capital charges exist per ERC—e.g., water plant ~$2,700+, wastewater ~$966+); private lateral/trenching ($50–$250+/ft); septic abandon ($500–$5,500); permits/inspections ($1,200–$3,800 multi-agency: DOH, DRER, WASD, plumbing); plumbing mods; grinder pump if needed ($2,000–$7,000); site restoration.
  • Assistance: Miami-Dade Septic-to-Sewer Financial Assistance (up to $15,000 grants/zero- or low-interest loans for homestead-exempt eligible homeowners based on income). Lateral Expansion Program installs public-side laterals. Check Connect 2 Protect / WASD for eligibility (sewer main availability required). City of Hialeah may have additional fees/schedules via Public Works.

Mandatory connection often required within 1–3 years once sewer is available. Contact City of Hialeah Public Works (305-556-3800) or Miami-Dade WASD for property-specific quotes, fees, and programs. Building/fee schedules are on hialeahfl.gov.

FLORIDA DRINKING WATER Summary and Recommendations

Hialeah water is safe and compliant with rigorous testing and advanced treatment (softening, RO, air stripping). Challenges center on infrastructure age, costs/bills, hardness, and occasional localized advisories rather than systemic contamination. For private wells/septic, conversions are driven by environmental protection (Connect 2 Protect) with financial aid available.

  • Download the latest CCR from hialeahfl.gov.
  • Monitor alerts; consider a certified filter (carbon for DBPs/taste; softener for hardness; RO for broader reduction) if concerned.
  • For hookups/fees: Call Public Works or visit city/county sites. Property-specific assessments needed.
