Hialeah Water Quality Report
Sources of Hialeah, Florida Drinking Water
The city of Hialeah (Miami-Dade County) sole source for drinking water is ground water from wells. The wells feed the Hialeah and John E. Preston, and Alexander Orr regional water treatment plants and the South Dade Water Supply System, which is comprised of five smaller water treatment plants that serve residents south of SW 264th Street in the unincorporated areas of the County. Is Hialeah's tap water safe to drink?

A list of contaminants in Hialeah, Florida Water Supply
(Detected above health guidelines)
Barium: Barium is a mineral present in rocks, soil and water. High concentrations of barium in drinking water increase the risk of cardiovascular disease and hypertension.
Health risks of barium in excess of health guideline: The health guideline of 700 ppb for barium was defined by the Environmental Protection Agency as a children's health-based limit for 10-day exposure, a non-enforceable federal health advisory. This health guideline protects against harm to internal organs.
Barium: Health Guideline: 700 ppb
- Hialeah, FL: 2300 ppb (Yikes - the legal limit is 2000 ppb)
- State: 18.1 ppb
- National: 68.2 ppb
Chlorate: Chlorate forms in drinking water as a byproduct of disinfection. Chlorate impairs thyroid function, making chlorate exposure most harmful during pregnancy and childhood.
Health risks of chlorate in excess of health guideline: Thyroid: The health guideline of 210 ppb for chlorate was defined by the Environmental Protection Agency as a benchmark for testing under the Unregulated Contaminant Monitoring Rule program. This health guideline protects against hormone disruption.
Chlorate: Health Guideline: 210.0 ppb
- Hialeah, FL : 286.7 ppb
- State: 293.8 ppb
- National: 114.0 ppb
Chromium (hexavalent): Chromium (hexavalent) is a carcinogen that commonly contaminates American drinking water. Chromium (hexavalent) in drinking water may be due to industrial pollution or natural occurrences in mineral deposits and groundwater.
Health risks of chromium (hexavalent) in excess of health guideline
The health guideline of 0.02 ppb for chromium (hexavalent) was defined by the California Office of Environmental Health Hazard Assessment as a public health goal, the level of a drinking water contaminant that does not pose a significant health risk. This health guideline protects against cancer.
Chromium (hexavalent): Health Guideline: 0.02 ppb
- Hialeah, FL: 0.0857 ppb
- State: 0.155 ppb
- National: 0.782 ppb
Radiological contaminants cancer: This utility detected Radium, combined (-226 & -228), Radium-226 & Uranium. Radiological contaminants leach into water from certain minerals and from mining. Drinking water contamination with radioactive substances increases the risk of cancer and may harm fetal development.
Radium is a radioactive element that causes bone cancer and other cancers. It can occur naturally in groundwater, and oil and gas extraction activities such as hydraulic fracturing can elevate concentrations.
Uranium is a known human carcinogen. The federal legal limit for uranium is set at 30 micrograms per liter (corresponding to parts per billion), but utilities can also report uranium in picocuries per liter (pCi/L), which is a measure of radioactivity in water. EWG translated all uranium results to pCi/L using a conversion factor developed by the EPA. With this conversion approach, the limit of 30 ppb corresponds to 20 pCi/L. Drinking water with this much uranium would cause more than 4.6 cancer cases in a population of 100,000. California set a public health goal for uranium of 0.43 pCi/L.
Radiological contaminants: Health Guideline: N/A - No standard exist for this contaminant.
Total trihalomethanes (TTHMs) cancer: Trihalomethanes are cancer-causing contaminants that form during water treatment with chlorine and other disinfectants. The total trihalomethanes group includes four chemicals: chloroform, bromodichloromethane, dibromochloromethane and bromoform.
Health risks of trihalomethanes in excess of health guideline
Cancer: The health guideline of 0.8 ppb for trihalomethanes was defined by the California Office of Environmental Health Hazard Assessment as a draft public health goal, the level of drinking water contaminant that does not pose a significant health risk. This health guideline protects against cancer.
Total trihalomethanes (TTHMs):
Health Guidelines: 0.8 ppb
- State: 23.2 ppb
- National: 23.4 ppb
- Hialeah, FL: 16.7 ppb
Fluoride: Fluoride occurs naturally in surface and groundwater and is also added to drinking water by many water systems, unfortunately the fluoride the add to the drinking water is not naturally occurring. The main chemicals used to fluoridate drinking water are known as “silicofluorides” (i.e., hydrofluorosilicic acid and sodium fluorosilicate). Silicofluorides are not pharmaceutical-grade fluoride products; they are unprocessed industrial by-products of the phosphate fertilizer industry. Since these silicofluorides undergo no purification procedures, they can contain elevated levels of arsenic — moreso than any other water treatment chemical. In addition, recent research suggests that the addition of silicofluorides to water is a risk factor for elevated lead exposure, particularly among residents who live in homes with old pipes.
- Legal Limit: 4 ppb
- State: 0.224 ppb
- National: 0.440 ppb
- Hialeah, FL: 0.870 ppb
