In-depth assessment of your municipal water supply
The water quality in Tampa, Florida has been comprehensively evaluated using data from the EPA's Safe Drinking Water Information System (SDWIS) and local water utility reports. Our analysis examines 9 distinct contaminants across multiple categories including inorganic chemicals, disinfection byproducts, microorganisms, and radionuclides. With an overall quality score of 69 out of 100 (Grade: C+), Tampa's water supply meets minimum EPA requirements but shows areas for improvement.
Tampa's primary water system, TAMPA WATER SYSTEM, serves approximately 388,544 residents. The water is sourced from a combination of surface and groundwater sources. Groundwater is generally naturally filtered through soil and rock layers, though it may contain elevated levels of minerals and naturally occurring contaminants like arsenic or radon.
Of the 9 contaminants analyzed in Tampa's water supply, 7 (78%) are present at safe levels below 50% of EPA Maximum Contaminant Levels (MCLs). 2 contaminants are detected at elevated levels between 50-100% of MCLs, warranting monitoring. No contaminants currently exceed EPA safety limits. The most common categories of concern in municipal water supplies include disinfection byproducts formed during the chlorination process, heavy metals like lead that can leach from aging infrastructure, and naturally occurring contaminants like arsenic or radium that vary by geographic region.
Tampa's water system has a compliance history with 6 documented EPA violations. Currently, 2 violations remain unresolved and under active remediation. Violations can range from monitoring and reporting failures to actual exceedances of contaminant limits. Water utilities are required by law to notify customers of any violations that may affect health and to take corrective action to return to compliance.
Water quality at the tap can differ from quality at the treatment plant due to distribution system conditions. Homes built before 1986 may have lead service lines or lead solder in plumbing that can contribute to lead exposure. Older galvanized pipes can harbor bacteria and release metals. Running cold water for 30 seconds to 2 minutes before drinking or cooking helps flush stagnant water from pipes. Residents in older homes should consider testing their water directly at the tap to assess any additional contamination from household plumbing, as EPA monitoring typically occurs at distribution points rather than individual residences.
Understanding potential health effects for residents
Certain groups face elevated health risks from water contaminants and should take extra precautions. Pregnant women are particularly vulnerable as contaminants like lead and nitrates can affect fetal development, potentially causing developmental delays and birth defects. Infants and young children are at heightened risk because their developing bodies absorb contaminants more readily and are more susceptible to their effects; lead exposure in children can cause irreversible cognitive impairment and behavioral problems. Elderly individuals and those with compromised immune systems (including cancer patients, organ transplant recipients, and HIV/AIDS patients) are more susceptible to waterborne pathogens and may experience severe illness from microorganisms that healthy adults can tolerate. Individuals with kidney disease should be aware of fluoride and other mineral levels, as impaired kidney function affects the body's ability to filter these substances.
Lead has been detected in Tampa's water supply. There is no safe level of lead exposure. In children, lead can cause developmental delays, learning difficulties, irritability, weight loss, hearing loss, and seizures. In adults, lead exposure contributes to cardiovascular problems, decreased kidney function, and reproductive issues. Pregnant women exposed to lead can transfer it to their developing fetus, increasing risk of premature birth and reduced growth. Use an NSF 53 certified filter and run cold water before drinking to reduce exposure.
Arsenic has been detected in Tampa's water supply. Long-term arsenic exposure, even at levels near EPA limits, is associated with increased risk of skin, lung, bladder, kidney, and liver cancers. Arsenic exposure can also cause cardiovascular disease, diabetes, and neurological effects. Skin changes like thickening and pigmentation may indicate chronic exposure. Reverse osmosis filtration is highly effective at removing arsenic from drinking water.
Elevated nitrate levels in Tampa's water pose particular risk to infants under six months. Nitrates can cause methemoglobinemia ("blue baby syndrome"), a condition where the blood cannot carry sufficient oxygen. Symptoms include bluish skin color, shortness of breath, and in severe cases, death. Formula-fed infants are at greatest risk. Pregnant women should also limit nitrate exposure. Boiling water does NOT remove nitrates—it actually concentrates them. Reverse osmosis or distillation systems effectively remove nitrates.
Based on Tampa's water quality profile, residents should consider the following protective measures: Installing a point-of-use water filter is strongly recommended given the current water quality score. Always use cold water for drinking and cooking, as hot water can contain higher levels of metals from pipes. Have your home tested if it was built before 1986 to check for lead plumbing. Review your annual Consumer Confidence Report (water quality report) from your utility to stay informed about local water quality trends. Pregnant women, families with young children, and immunocompromised individuals should consult healthcare providers about water safety precautions specific to their situation.

What your city's grade of C+ means for you and your family
Tampa's water quality score of 69 out of 100 places it in the fair category, indicating that while the water supply functions as a municipal system, there are notable concerns that residents should take seriously. A score below 70 means the water has multiple contaminants at elevated concentrations, a history of compliance issues, or both. While no contaminants currently exceed EPA limits, 2 are detected at elevated levels, indicating the treatment system is under pressure.
The national average water quality score is approximately 72, which means Tampa falls 3 points below the national average. This is a significant gap that translates to measurably higher contaminant exposure for residents who drink unfiltered tap water. Among the 9 contaminants tested, 2 are present at levels above 50% of their EPA limits. At these concentrations, while individual contaminant levels may be technically within legal bounds, the cumulative exposure from multiple elevated contaminants is a concern that EPA limits do not fully address, as they evaluate each contaminant in isolation.
For Tampa residents, we strongly recommend investing in a water filtration system. A reverse osmosis system is the most effective choice given the range of contaminants detected, as it removes 95-99% of dissolved solids, heavy metals, and chemical contaminants. Additionally, consider having your home's water independently tested at the tap, as distribution system conditions and household plumbing can further affect what comes out of your faucet.
Practical steps based on your city's specific water quality profile
Based on our analysis of Tampa's water quality data, here are targeted recommendations for residents. These steps are prioritized according to the specific contaminants and issues identified in your water supply.
Lead has been detected in Tampa's water supply. Since there is no safe level of lead exposure, take these precautions: Use only cold water for drinking and cooking, as hot water leaches more lead from pipes. Flush your faucet by running cold water for at least 30 seconds before each use, especially after the water has been sitting for several hours. If your home was built before 1986, it likely has lead solder in the plumbing; consider having a licensed plumber inspect your service line. For homes with confirmed lead plumbing, an NSF 53 certified pitcher filter or under-sink reverse osmosis system effectively removes lead. Have your water tested at the tap through a state-certified lab to determine your household's specific lead levels.
Arsenic has been detected in Tampa's water supply. Arsenic is odorless and tasteless, making filtration essential since you cannot detect it by smell or appearance. Reverse osmosis systems are the most effective household treatment for arsenic, typically removing over 95%. Distillation is also effective. Standard carbon filters do NOT adequately remove arsenic. Boiling water actually concentrates arsenic rather than removing it, so never boil water as a treatment for arsenic contamination. If you rely on well water in addition to municipal supply, have it independently tested for arsenic, as levels can vary significantly by location.
Nitrates are present in Tampa's water, which is especially important for households with infants. Do NOT boil water to treat nitrates, as boiling concentrates them. Reverse osmosis and ion exchange systems are effective at removing nitrates. Distillation also works but is less practical for daily use. If you have an infant under six months who is formula-fed, use filtered or bottled water for formula preparation until you can confirm nitrate levels at your tap are below 10 mg/L. Pregnant women should also minimize nitrate exposure. Agricultural runoff is the most common source of nitrate contamination in municipal water supplies.
How to contact your water provider and access official reports
The primary water provider for Tampa is TAMPA WATER SYSTEM (Public Water System ID: FL348707), serving approximately 388,544 residents. This utility is responsible for treating, testing, and delivering drinking water that meets EPA standards under the Safe Drinking Water Act. As a regulated public water system, it is required to conduct regular testing for over 90 contaminants and publish results in an annual Consumer Confidence Report (CCR) that must be made available to all customers by July 1 each year.
Your water utility is legally obligated to notify customers within 24 hours of any violation that poses an immediate health risk, and within 30 days for less urgent violations. If you are concerned about your water quality, you have the right to request testing data from your utility at any time. For independent verification, you can have your water tested at the tap by a state-certified laboratory. The EPA maintains a list of certified labs by state at epa.gov/dwlabcert. Home testing is particularly important because it captures contamination from your household plumbing that utility testing at distribution points would not detect.

Arsenic is present, and RO systems typically remove over 95% of arsenic. A quality RO system costs approximately $150-300 and is installed under the kitchen sink. Even in cities with good water quality, a filter provides an additional layer of protection against contaminants that may enter water from your home's plumbing. View our water filter comparison guide for specific product recommendations.
Tampa's primary water system, TAMPA WATER SYSTEM (PWS ID: FL348707), sources water from a combination of surface and groundwater sources, which provides resilience in the water supply but means the utility must manage treatment for the different contamination profiles of each source type. This system serves approximately 388,544 residents.
Yes, lead has been detected in Tampa's water supply. The EPA has established that there is no safe level of lead exposure, making this a priority concern especially for households with children or pregnant women. Lead typically enters drinking water through corrosion of lead service lines and lead solder in household plumbing, particularly in homes built before 1986. To reduce exposure: always use cold water for drinking and cooking, flush the tap for 30 seconds to 2 minutes after periods of non-use, and install an NSF 53 certified filter. Consider having your water independently tested at the tap, as lead levels can vary significantly from house to house depending on plumbing age and condition.
Yes, Tampa's water system has 6 documented EPA violations in its compliance history. 2 violations remain unresolved and should be actively addressed by the water utility. Violations can include exceeding contaminant limits, failure to conduct required testing, or failure to properly notify customers. Water utilities are required by the Safe Drinking Water Act to address violations and notify affected customers. You can look up the full violation history through the EPA's ECHO database or by contacting your water utility directly.
There are several options for testing your water in Tampa. For the most comprehensive results, use a state-certified laboratory (find one at epa.gov/dwlabcert). Home test kits like Tap Score provide EPA-certified lab analysis with easy-to-understand results. Basic test strips available at hardware stores can screen for common parameters like chlorine, pH, hardness, and lead, though they are less accurate than laboratory testing. You can also request the latest testing data directly from TAMPA WATER SYSTEM. Testing at your tap is important because it captures contamination from your household plumbing that city-level monitoring at distribution points does not detect.
