01The verdict: is Quincy water safe?
Quincy's drinking water has significant quality concerns based on EPA testing data. With a grade of F (37.6/100), the system has issues across multiple categories. A water filter is recommended for all residents. The city's 16 water systems serve approximately 64,670 residents using groundwater (wells).
51 unresolved violations on record
EPA records show open compliance items for this system. Most are administrative, but unresolved items are worth watching.
See what was cited ↓Lead is well under the limit
90th-percentile lead is 4.9 ppb — beneath the 15 ppb federal action level and under the 5 ppb watch threshold.
See the trend ↓lithium is approaching its limit
Measured at 12.9000 µg/L — 120% of the 0.004 µg/L limit. Within the rules, but with less headroom than you'd want.
See the ledger ↓Quincy's drinking water received a grade of F (37.6 out of 100), indicating failing water quality. The city's 16 water systems serve approximately 64,670 residents using groundwater.
Lead levels were measured at 4.9 ppb (90th percentile), well within EPA limits. UCMR 5 testing detected 3 PFAS compounds, with levels exceeding EPA maximum contaminant levels in the water supply. The system has 194 violations on record, including 32 health-based violations. 51 remain unresolved.
Quincy ranks #348 out of 366 cities in Florida for water quality, placing it among the lowest-rated in the state. Quincy relies on groundwater, which is generally less vulnerable to surface contamination but can be affected by naturally occurring minerals like arsenic and nitrate, as well as agricultural and industrial runoff. Of particular concern: PFAS "forever chemical" levels exceed the 2024 EPA maximum contaminant levels. These synthetic compounds don't break down naturally and require specialized filtration such as reverse osmosis or granular activated carbon. Hexavalent chromium (chromium-6) was detected at 2.10 µg/L in UCMR 3 testing. While below California's 10 µg/L limit and with no federal MCL set, residents sensitive to this contaminant may consider reverse osmosis filtration. The system has seen 20 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.
02What's in Quincy's water
Every contaminant flagged in Quincy, on one shared scale: distance to its own legal limit. The red line is the limit — anything past it is out of compliance, and the closer a bar gets, the less headroom the system has.

04Where Quincy's water comes from
Quincy's drinking water is drawn from underground aquifers through wells.
Groundwater
Underground aquifers reached by wells — naturally filtered, but can carry minerals like arsenic and nitrate.
Local treatment
Groundwater generally needs less treatment — typically disinfection and, where needed, mineral removal.
16 systems
16 water systems, operated under public/private ownership.
64,670 people
Residents served across Quincy's service area.
Groundwater is naturally filtered through rock and soil layers, generally requiring less treatment than surface water. However, it can contain naturally occurring contaminants like arsenic, radon, and minerals. Agricultural activity, septic systems, and industrial operations near well fields can introduce nitrates, pesticides, and volatile organic compounds. The system is operated by public/private ownership and serves approximately 64,670 people through 16 water systems.

Water bodies near Quincy
These water bodies shape the regional watershed and can indirectly affect groundwater quality.
05Pressure on Quincy's watershed
Outside forces that shape what reaches the treatment plant. None of these is a verdict on the tap by itself — but each adds pressure worth knowing about.
Industrial discharge
1 facility within 10 miles reported 0 lb released to surface water in the latest EPA Toxics Release Inventory. Proximity doesn't equal tap contamination — treatment and hydrology decide — but it's pressure on the watershed.
Flood & storm history
10 federal disaster declarations on record for Gadsden County. Flooding and severe storms can overwhelm treatment plants, cause sewage overflows, and push runoff into supplies.
Superfund proximity
1 National Priorities List site within 10 miles. Proximity does not necessarily indicate tap-water contamination — the connection depends on hydrology and treatment.
Drought
Gadsden County is in D1 (moderate drought) per the U.S. Drought Monitor (week of Jul 2026). Drought can raise disinfection-byproduct levels and taste/odor issues as utilities draw from lower reservoirs.

07What to do at home
Steps matched to what testing actually found in Quincy's water — not generic advice.
Filter drinking & cooking water
Reverse osmosis system. PFAS compounds exceed EPA maximum contaminant levels
Compare tested filters →Flush taps & check your service line
Lead leaches from pipes as water sits. Run cold water 30 seconds before drinking (especially mornings), and ask the utility whether your address still has a lead service line.

All water alerts →Frequently asked questions
Is Quincy, FL tap water safe to drink?
Quincy's water quality earned a grade of F (37.6/100). Significant issues have been found. A water filter is strongly recommended. The city ranks #348 out of 366 cities tested in Florida.
What contaminants are in Quincy's water?
Lead was measured at 4.9 ppb (90th percentile). 3 PFAS compounds were detected. 194 violations are on record.
How is Quincy's water quality grade calculated?
The grade is based on four factors: violation history (40%), lead and copper levels (25%), PFAS contamination (25%), and regulatory compliance (10%). The score is also adjusted based on how complete the available data is. See our methodology page for full details.
Do I need a water filter in Quincy?
PFAS compounds exceed EPA limits — a reverse osmosis or activated carbon filter is recommended.
Where does Quincy's water come from?
Quincy's water is sourced from Groundwater. The city has 16 water systems serving approximately 64,670 residents.
What health violations has Quincy's water system had?
Quincy has 32 health-based violations on record. The most recent violation was recorded in October 2022. Health-based violations mean the water exceeded EPA maximum contaminant levels (MCLs) for a regulated substance. 51 violations remain unresolved.
Is Quincy's groundwater at risk of contamination?
Quincy uses groundwater, which can be affected by naturally occurring contaminants like arsenic, radon, and nitrate, as well as agricultural runoff and industrial activity. The system has 194 violations on record that may relate to groundwater quality. Groundwater systems are generally less susceptible to surface contamination but should be monitored for emerging contaminants like PFAS.
Why does Quincy have so many PFAS compounds in its water?
3 different PFAS "forever chemical" compounds were detected in Quincy's water supply during UCMR 5 testing. PFAS contamination often originates from proximity to military installations (AFFF firefighting foam), airports, industrial manufacturing sites, or wastewater treatment facilities. Some levels exceed the 2024 EPA maximum contaminant levels — a reverse osmosis or NSF-certified activated carbon filter is strongly recommended.
How does Quincy's water compare to other cities?
Quincy ranks #348 out of 366 cities in Florida (better than 5% of state cities) and #15052 out of 15382 cities nationally (2th percentile). The grade of F reflects the combined assessment of violation history, lead and copper levels, PFAS contamination, and regulatory compliance.
