Why Some Poquoson Homeowners Add Reverse Osmosis at the Kitchen Sink
Poquoson is served by Newport News Waterworks’ Lower Peninsula system. The 2025 report says the utility meets applicable state and federal drinking-water standards, while the same report and expanded data still show measurable minerals, disinfection byproducts and PFAS that some homeowners may want to reduce further in their drinking water.
PFAS
The 2025 expanded Lower Peninsula data reports PFOA, PFOS, PFHxS, PFBA, PFHxA and PFPeA. A properly selected RO system can provide point-of-use reduction for specified PFAS when the exact equipment supports those claims.
Lead at the Tap
Waterworks reports no lead detected in treated water tested monthly at its treatment plants, but lead exposure can still be property-specific because service-line and household plumbing materials vary. RO can reduce lead when rated for it.
Fluoride
Newport News Waterworks adds fluoride and reported 0.77 ppm in the 2025 Lower Peninsula results. Reverse osmosis is commonly used when a homeowner specifically wants fluoride reduction at the drinking faucet.
Nitrate
The 2025 report lists nitrate at 0.065 ppm, below the 10 ppm federal MCL shown in the report. RO is a point-of-use option for homeowners seeking additional nitrate reduction.
Hexavalent Chromium
EWG’s data for the shared Newport News Waterworks utility lists hexavalent chromium above EWG’s non-enforceable health guideline. RO may reduce chromium when the installed system is appropriately rated.
Disinfection Byproducts
The 2025 utility report lists TTHM and HAA5, while EWG also flags several disinfection byproducts above its health guidelines for this shared regional system. Carbon pretreatment and RO can provide additional point-of-use treatment depending on the compound and system.
Chloramine-Treated Water
Waterworks uses chloramines as its secondary disinfectant. The carbon stage ahead of an RO membrane helps protect the membrane and can improve drinking-water taste when the cartridge is selected for the feed water.
Dissolved Minerals
Waterworks reported average hardness of 69 mg/L as calcium carbonate in 2025. RO reduces dissolved minerals at the drinking faucet, but it is not a whole-home hardness treatment system.
See Poquoson’s water data in context.
The Poquoson Water Problems page compares the 2025 Newport News Waterworks Lower Peninsula report with EWG’s separate health-guideline data and explains which concerns are point-of-use versus whole-home treatment issues.
Poquoson public-water hardness: Newport News Waterworks reported an average of 69 mg/L as CaCO3 in 2025, with a range of 63–75 mg/L, and describes the water as moderately hard. Reverse osmosis treats drinking and cooking water at one point of use; it does not soften water throughout the home.
How the Protector Reverse Osmosis System Works
Each stage protects the system, reduces contaminants and improves finished-water taste.
Sediment Filter
Captures rust, dirt, sand and suspended particles.
Activated Carbon
Reduces chlorine and taste-and-odor compounds.
RO Membrane
Separates purified water from many dissolved contaminants.
Polishing Filter
Provides final taste enhancement before dispensing.
Broad Drinking-Water Contaminant Reduction
Exact performance depends on the installed membrane, cartridges, certification, feed-water conditions and maintenance.

Does reverse osmosis make sense if Poquoson public water already meets standards?
It can. The public system report addresses regulatory compliance across the Lower Peninsula system. Reverse osmosis is an optional point-of-use treatment for homeowners who want additional reduction of dissolved substances in the water they drink and cook with.
Does reverse osmosis remove PFAS?
RO can reduce specified PFAS compounds when the exact system is tested or certified for those claims. The 2025 Lower Peninsula expanded data reports several PFAS compounds, so system selection should be based on the specific reduction claims you want.
Does RO remove lead?
RO can reduce lead at the drinking faucet when the selected system is rated for lead reduction. This can matter because lead risk can be influenced by service-line and household plumbing materials even when treated-water samples at the plant do not show lead.
Does RO remove fluoride?
Reverse osmosis is commonly used for fluoride reduction. Newport News Waterworks adds fluoride and reported 0.77 ppm in the 2025 Lower Peninsula results.
Will RO soften all the water in my Poquoson home?
No. RO treats drinking and cooking water at one point of use. Waterworks reported moderately hard water in 2025, but whole-home hardness treatment is a separate job handled by a water conditioner or softener when appropriate.
Can the system connect to my refrigerator?
Many installations can include a line to a compatible refrigerator ice maker or water dispenser, depending on the kitchen layout and appliance requirements.
How often should the system be serviced?
Annual service is appropriate for many households, though filter life depends on water use, feed-water conditions and the installed cartridges.
Does the free in-home water test include PFAS laboratory testing?
No. The free in-home evaluation is not certified PFAS testing or a complete laboratory contaminant analysis. It is intended to help evaluate common household water conditions and treatment goals.
