01The verdict: is Ocala water safe?

Ocala's drinking water has significant quality concerns based on EPA testing data. With a grade of F (39.5/100), the system has issues across multiple categories. A water filter is recommended for all residents. The city's 13 water systems serve approximately 1,460 residents using groundwater (wells).

The concern

PFOS is over its legal limit

Measured at 0.0064 µg/L against the EPA MCL of 0.004 µg/L. The ledger below shows how far over — and which filter removes it.

The good news

Lead is well under the limit

90th-percentile lead is 0.0 ppb — beneath the 15 ppb federal action level and under the 5 ppb watch threshold.

Recent compliance history is the best predictor of future problems — the year-by-year record is below.

See the record ↓

Ocala's drinking water received a grade of F (39.5 out of 100), indicating failing water quality. The city's 13 water systems serve approximately 1,460 residents using groundwater.

Lead levels were measured at 0.0 ppb (90th percentile), well within EPA limits. UCMR 5 testing detected 6 PFAS compounds, with levels exceeding EPA maximum contaminant levels in the water supply. The system has 240 violations on record, including 9 health-based violations. 54 remain unresolved.

Ocala ranks #484 out of 487 cities in Missouri for water quality, placing it among the lowest-rated in the state. Ocala 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. As a small community water system, Ocala may have fewer resources for advanced treatment technologies and infrastructure upgrades compared to larger utilities. The system has seen 58 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.

02What's in Ocala's water

Every contaminant flagged in Ocala, 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.

Over MCL — EPA MCL: 0.004 µg/L

PFAS "forever chemicals" exceed the 2024 EPA maximum contaminant levels, which utilities must meet by 2029. These compounds don't break down in the body or the environment. Reverse osmosis (NSF/ANSI 58) or certified granular activated carbon (NSF/ANSI 53) removes them at the tap.

03Ocala's ten-year track record

Each box is one year. A green check means no EPA violations; a numbered badge counts that year's violations — red if any were health-based, amber if they were monitoring or paperwork issues. The system has 240 violations on record, including 9 health-based violations. 54 remain unresolved.

3 of the last ten years were clean. The numbered years had EPA violations — red when any were health-based, amber when they were paperwork or missed-testing issues.

04Where Ocala's water comes from

Ocala's drinking water is drawn from underground aquifers through wells.

Source

Groundwater

Underground aquifers reached by wells — naturally filtered, but can carry minerals like arsenic and nitrate.

Treatment

Local treatment

Groundwater generally needs less treatment — typically disinfection and, where needed, mineral removal.

Distribution

13 systems

13 water systems, operated under public/private ownership.

Delivery

1,460 people

Residents served across Ocala'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 1,460 people through 13 water systems.

Do I need a water filter in Ocala?

PFAS compounds exceed EPA limits — a reverse osmosis or activated carbon filter is recommended.

Where does Ocala's water come from?

Ocala's water is sourced from Groundwater. The city has 13 water systems serving approximately 1,460 residents.

What health violations has Ocala's water system had?

Ocala has 9 health-based violations on record. The most recent violation was recorded in December 2025. Health-based violations mean the water exceeded EPA maximum contaminant levels (MCLs) for a regulated substance. 54 violations remain unresolved.

Is Ocala's groundwater at risk of contamination?

Ocala 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 240 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 Ocala have so many PFAS compounds in its water?

6 different PFAS "forever chemical" compounds were detected in Ocala'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 Ocala's water compare to other cities?

Ocala ranks #484 out of 487 cities in Missouri (better than 1% of state cities) and #14909 out of 15382 cities nationally (3th percentile). The grade of F reflects the combined assessment of violation history, lead and copper levels, PFAS contamination, and regulatory compliance.
