Problems We Found With Hialeah's Drinking Water

Emma Schultz, M.S. | Scientific Contributor   

For our Hialeah water quality report, we aggregated water quality test data from the City of Hialeah’s Department of Public Works, the U.S. Environmental Protection Agency (EPA), as well as from samples that we collect and analyze.  We cross reference these data with toxicity studies in the scientific and medical literature, and look at upcoming regulatory changes. The water filters that we sell in Hialeah are optimized with these issues in mind.

Source Of Hialeah Drinking Water

The city of Hialeah's drinking water is groundwater-sourced, and comes from the Biscayne and Upper Floridan Aquifers. Most of Hialeah’s water is purchased from Miami-Dade County; water pumped from the Biscayne Aquifer is treated at facilities owned and operated by Miami-Dade County before being distributed to Hialeah. The Hialeah Reverse Osmosis Water Treatment Plant is jointly owned by the City of Hialeah and Miami-Dade County. Water at this plant is pumped from the Upper Floridan Aquifer.

Arsenic In Hialeah Drinking Water

Arsenic is a dangerous heavy metal known to cause cancer, among other health problems. Arsenic originates in source water.  While the city of Hialeah's water is in compliance with EPA water quality standards, consumers should take note that the EPA's standard balances toxicity against the costs of removing arsenic from drinking water; the standard is therefore quite high. Hialeah’s most recent tap water quality report listed average arsenic concentrations ranging from 0.8-1.5 parts per billion for Miami-Dade County water, with an average concentration of 1.5 ppb.  We strongly advocate that tap water with more than 1 part per billion be treated to remove arsenic, especially if there are children in the home.

Lead In Hialeah Drinking Water

Lead enters consumer tap water through old lead service pipes and lead-containing plumbing. When corrosion control measures fail (such as recently happened in Flint, Michigan), lead leaches into drinking water and can reach toxic levels. Recent analysis for lead in the city of Hialeah's water found a 90th percentile concentration of 2.1 ppb, with one location (out of 124 sampled) exceeding the Action Level of 15 ppb. Despite the Action Level being set at 15 ppb, both the EPA and CDC recognize that there is no such thing as a safe level of lead. In addition, federal regulations cannot possibly take into account levels measured at an individual tap.

Chromium 6 In Hialeah Drinking Water

Chromium 6 is a highly toxic metal that, while monitored, is not regulated by the EPA. The city of Hialeah’s tap water recently averaged 66 parts per trillion for chromium 6. These average levels are 3.3 times higher than the concentration determined to have a negligible impact on cancer risk.

Disinfection Byproducts (DBPs) In Hialeah Drinking Water

DBPs are a category of emerging contaminants that form when chlorine-based disinfectants react with naturally-occurring organic matter.  Although these chemicals are not well regulated, the EPA has stated that they are associated with an increased risk of bladder cancer, as well as kidney, liver, and central nervous system problems. DBPs in the city of Hialeah’s tap water had a 2016 local running annual average of 43 parts per billion.

Use Of Chlorine and Chloramine In Hialeah Tap Water

Like most cities in the United States, Hialeah’s Reverse Osmosis plant adds chlorine to its water supply to keep consumers safe from waterborne pathogens. 2016 levels of chlorine, while under the Maximum Residual Disinfect Level of 4.0 ppb, averaged 3.2 ppb, close to the MRDL threshold. While not considered harmful in low concentrations, many people find that removing the chlorine from their water supply results in a taste and odor improvement.

Unlike the Hialeah RO plant, Miami-Dade County’s water is disinfected with chloramine, which is produced by mixing chlorine and ammonia.  Chloramine is responsible for what many customers report as the “bad taste”of tap water, and unlike chlorine this bad taste will not fade if a container of water is left in the fridge overnight.  Most one-size-fits-all water filters use filtration media that doesn’t adequately remove chloramine, but the filters that Hydroviv builds for Hialeah’s Miami-Dade water use special filtration media that is purpose-built to remove chloramine as well.

In 2016, the local running annual average for chloramines was 2.6 ppm and the upper detected range was 4.5 ppm, which is over the MRDL of 4.0 ppm. Based on previous Hialeah local running annual water averages, this is an Maximum Contaminant Level violation.

When you choose to filter your tap water for either chlorine or chloramine, especially with levels as high as those in Hialeah, we believe you will notice an immediate taste enhancement.


Still Have Questions About Hialeah’s Tap Water?

Hydroviv is a water filtration company that uses water quality data to optimize water filters for each city’s water.  The chemicals that we list above are what we consider to be “points of emphasis” so we can build the best water filter for Hialeah tap water, but all of our water filters provide broad protection against other contaminants commonly found in drinking water (e.g. VOCs, heavy metals [including lead], pharmaceuticals, solvents, pesticides, mercury).

Problems We Found With St. Petersburg, Florida Drinking Water

Emma Schultz, M.S. | Scientific Contributor  
Updated August 1, 2019 to include current data 

Our Water Nerds have updated our assessment of St. Petersburg drinking water to include the most current data. To do this, we aggregated water quality test data Water Resources Department, the U.S. Environmental Protection Agency (EPA), as well as from samples that we collect and analyze. Our team is then able to cross reference these data with toxicity studies in scientific literature. The water filters that we sell in St. Petersburg are optimized with this information in mind. 

Source Of St. Petersburg Drinking Water

The City of St. Petersburg gets drinking water from a mix of groundwater and surface water sources. St. Petersburg is part of Tampa Bay Water, along with six other regional members. Groundwater originates from eleven well fields from the Floridan aquifer. Surface-based water comes from the Alafia River, the Hillsborough River, the C. W. Bill Young Regional Reservoir, and the Tampa Bypass Canal. 

Lead In St. Petersburg Drinking Water

Lead enters into St. Petersburg consumer's tap water through old lead service pipes and lead-containing plumbing. When corrosion control measures fail (as recently witnessed in Flint, Michigan), lead leaches into the drinking water, reaching toxic levels. Recent analysis for lead in St. Petersburg found an average of 1.9 parts per billion. EPACDC and the American Academy of Pediatrics all recognize that there is no safe level of lead for children. Federal regulations cannot possibly take into account levels measured at an individual tap.

Chromium 6 In St. Petersburg Drinking Water

Chromium 6 is a highly toxic metal that is not regulated by the EPA. St. Petersburg’s tap water recently averaged 82 parts per trillion for chromium 6. These levels are 4 times higher than the concentration determined to have a negligible impact on cancer risk.

Use Of Chloramine In St. Petersburg Tap Water

While most cities use chlorine as the primary disinfectant, St. Petersburg’s water is disinfected with chloramine, which is made by combining chlorine and ammonia. Chloramine is the frequent issue when customers report a “bad taste” in their tap water, and unlike chlorine will not fade away if left in the fridge overnight. The recent chloramine running annual average for St. Petersburg was 3.81 parts per million, with samples ranging as high as 6.6 ppm; the maximum residual disinfectant level, in comparison, is only 4.0 ppm. Most one-size-fits-all water filters use filtration media that don’t adequately remove chloramine, but the filters that Hydroviv builds for St. Petersburg use special filtration media that are purpose-built to remove chloramine as well.

Problems We Found In Miami, Florida Drinking Water

Kezia Snipe | Hydroviv Research Analyst
Updated August 5, 2019 to include current data

Our Water Nerds have updated our assessment of Miami drinking water to include the most current data. We aggregated test data from the Miami Dade County Water And Sewer, the U.S. Environmental Protection Agency (EPA), as well as from samples that we collect and analyze. Our team them cross references these data with toxicity studies in scientific and medical literature, and look at upcoming regulatory changes. The water filters that we offer at Hydroviv are optimized to remove contaminants in Miami drinking water. 

Source Of Miami Drinking Water

The primary source of Miami's drinking water comes from the Biscayne Aquifer and is located just below the land surface in South Florida.

Lead In Miami Drinking Water

Lead enters Miami's drinking water through older lead service pipes and lead-containing plumbing. When corrosion control measures put in place by the municipality fail (like what recently happened in Flint, Michigan), lead leaches into the drinking water, and can reach dangerous levels. The current 90th percentile in Miami drinking water is 2.3 parts per billion, and 1 out of 57 samples exceeded the federal Action Level. Though Miami is in compliance with federal regulations, the EPA and CDC have both acknowledged that there is no safe level of lead for children, and federal regulations do not take into account levels measured at an individual tap. The American Academy of Pediatrics recommends that any taps used to serve children have lead levels no higher than 1 part per billion.

Chromium 6 In Miami Drinking Water

Chromium 6 is an extremely toxic metal that is not currently regulated by the EPA. In recent years, Miami water quality averaged 86 parts per trillion. For the sake of perspective, these levels are nearly 4 times higher than the concentration determined to have negligible impact on cancer risk

Disinfection Byproducts (DBPs) In Miami Drinking Water

DBPs are a category of emerging contaminants that form when chlorine-based disinfectants react with naturally-occurring organic matter. Although these chemicals are not currently regulated very well, the EPA has acknowledged that they are associated with an increased risk of bladder cancer, as well as kidney, liver, and central nervous system problems.

Still Have Questions About Miami Drinking Water?

Hydroviv is a water filtration company that uses water quality data to optimize water filters for each customer's water. The contaminants that we list above are what we consider to be major “points of emphasis” that we use to build water filters that are built specifically for Miami, but all of our our filters provide broad protection against a wide range of contaminants (including lead).
