42–94mg/L as CaCO₃
≈ 2.4–5.5 grains per gallon
Reported utility hardness. A softener reduces the minerals that cause scale; a standard filter does not soften water.
3.4ppm
Report comparison: 4 ppm disinfectant limit.
The displayed result is the report’s compliance average. Individual samples can be higher. Filtration can target disinfectant taste and odor.
Not detected
No amount above the reporting threshold in the listed monitoring.
Not detected does not mean zero. Reporting thresholds are not the same as regulatory limits or health goals.
0.23ppm
Report comparison: 4 ppm federal primary limit.
This is a historical sample, not a statement about current fluoridation. Fluoride reduction needs a dedicated treatment option.
60.4ppb
Reported compliance value.
Reported compliance values differ from individual sample peaks. Check the full table for ranges, dates and how each result was calculated.
29.5ppb

Reported compliance values differ from individual sample peaks. Check the full table for ranges, dates and how each result was calculated.
1.2ppb
90th percentile across sampled taps.
A 90th-percentile result is not your tap result or the highest sample. Below an action level does not mean zero risk; lead’s health goal is zero.
0.0378ppm
90th percentile across sampled taps.
A utility percentile does not tell you the level at your own tap.

Find My Water System →Explore well-water systemsTHE DETAILS BEHIND THE HIGHLIGHTS
Explore the available local reports below. Each table names its supplier and dates; results from different providers are not interchangeable. The provider selector changes your highlights, while this section keeps the county’s source tables together.
The detailed results and hardness figures shown here come from verified 2024 utility reports, with older sample dates retained. The county and city both list 2025 reports; those newer numerical tables are not reproduced here. Open the current report for your supplier below.
ppm = mg/L; ppb = µg/L; ppt = ng/L. ND means below detection, not zero. MCL and MRDL are regulatory benchmarks reported in the source; action levels trigger system action. Annual averages, individual samples and household-tap percentiles are different measures. Compare like with like.

These results describe Collier County Regional Water Treatment Plant (FL5114069), not every home or water system in Collier County. Match this system to your water bill before using the results.

Results come from different testing periods. A detection is not, by itself, a finding that water is unsafe. “Not detected” means below the test’s reporting level; it does not mean zero. Missing results mean we have not verified that data here.
MyTapWater reports no detections in this panel. Reporting limits vary by compound. The named compounds below are those individually verified in the retrieved source; the full panel is available through the source link. Selected PFAS sample dates: 2024-10-21 – 2025-04-23
MyTapWater reports lithium was tested and not detected. Sample dates and reporting limits: see the source report.
Selected historical tests, with their original dates. “Detected” means at least one positive result in the listed period. “Below reporting level” means all retrieved samples for that entry were below the reporting level. These older tests do not describe today’s water at your tap.

A list of tested substances is not a list of what a filter removes. Choose a system using its verified contaminant-reduction specifications and your water source. A softener addresses hardness. Use the published hardness for your provider or a home test to choose softening for scale control.
No. Check the utility name on your bill. The county utility and City of Naples have different reports; other providers and private wells need their own water information. Source
Regional groundwater and delivered drinking water are different measurements. Collier’s report describes membrane treatment and lime softening. Use the dated finished-water figure for your supplier, then test at home before deciding on a softener. Source
No. Utility reports describe particular systems and sample periods. Plumbing, service lines and treatment already in a home can change the result at the tap.
No. Select equipment by its specific tested or certified reduction claims and rated flow. A long contaminant list is not evidence that a particular system removes every item.
No result rows match that search. Try another substance or clear your search.
Next, match the equipment to your home and water source.
These labels compare a reported result with its stated benchmark. They are not a blanket safety rating. Health goals, compliance limits, action levels and reporting thresholds mean different things.

More about your local water
For Naples, start with the named provider and source dates above. Where a separate city dataset is not available, this guide uses Collier County reference records. Those records describe the listed utility, not every home in the city.
This Naples guide uses the named utility records from our county reports. The provider name, dates and source on each result show which system it describes. City boundaries alone do not identify your supplier.
City of Naples · local utility source ↗USGS classifies 0–60 mg/L as soft, 61–120 as moderately hard, 121–180 as hard and above 180 as very hard. These describe mineral content, not a health-based limit. A regional map cannot replace a home hardness test.
USGS hardness classifications and limitationsFiltration can address taste, odor, sediment and specific substances when the treatment is designed for them. A softener reduces calcium and magnesium. Your water source, actual hardness and household flow needs guide the combination.
Compare filters and softenersA county or utility report does not test your plumbing or private well. It also cannot prove that a particular filter removes every substance shown. Check the exact system’s treatment stages and verified claims for your goal.
What a whole-house filter can addressA city name, mailing address or ZIP code alone does not establish your water supplier. Municipal systems, county utilities and private wells can serve different addresses in the same area.
Bathroom count and simultaneous water use help size the filter. Your plumber checks the main water line, installation space and drain access. Condos and homes with shared plumbing may need building approval or a different installation.
For a private well, use a current well-water test to choose treatment. Public utility reports do not measure your well.

View water report →A useful local question
This guide uses the named utility records from our county reports, with local utility links where available. The supplier, sampling period and source stay attached to each result. Confirm the provider on your bill before applying a result to your home.
Check the water-hardness highlight for the selected provider. It distinguishes a utility result, a regional estimate and unavailable data. A regional estimate is not a measurement of treated water at your tap. Test your incoming water to confirm hardness for system sizing.
A softener is recommended for scale control when the reported or measured hardness supports it. The recommendation beside the highlights explains that distinction. Unknown hardness is not zero; test it before selecting and programming a softener.
Start with a whole-house filter sized for your bathrooms and simultaneous water use. Match its treatment media and verified model-specific reduction claims to your goals. A softener reduces hardness minerals. You choose, hire and pay your own licensed plumber for installation.
No. Answer the home-sizing questions to get started. Your licensed plumber confirms the installation fit. A street address is not required in the matching form.
Each highlight links to its source. Open the full report for the longer tables, sampling details and additional source documents. A date on one result does not update every other result on the page.
Utility measurements take priority over regional estimates when they are available for that provider. Source dates are preserved. Hardness is converted using mg/L as CaCO₃ ÷ 17.1; regional estimates are not presented as home measurements.
