Portsmouth's reported tap-water supply comes from Lake Meade, with influence from Lakes Cohoon and Kilby, Speight's Run Reservoir and five deep wells. The city reports that the Lake Kilby Water Treatment Plant can treat up to 32 million gallons per day and serves more than 150,000 customers in Portsmouth, Chesapeake and Suffolk.
Official Standards and EWG Health Guidelines Are Not the Same Thing
Portsmouth's 2025 municipal report lists the regulated substances it detected and marks the reported 2025 entries as having no listed violation. It also includes a separate notice about a missed routine lead-and-copper monitoring round and the city's corrective sampling.
EWG evaluates utility data against its own health-based guidelines, which can be much lower than federal or state legal limits. That difference is why an EWG exceedance should not be described as a legal violation.
EWG's Portsmouth Utility Page
EWG currently lists 11 contaminants above its health-based guidelines for the City of Portsmouth utility. Its database uses a different benchmark and data period than the city's annual compliance report.
The Portsmouth Water Problems page separates EWG health-guideline comparisons from EPA/state drinking-water standards so the two are not confused.
Choose Treatment for the Water Goal You Actually Have
A whole-home conditioner, reverse osmosis system and PFAS filtration system are built for different treatment goals. Start with the water concern and choose the system designed for it.
Whole-Home TreatmentPortsmouth Water Conditioners
Whole-home conditioning can address hardness and scale while providing treatment throughout showers, sinks, laundry and connected appliances.
- Whole-home water treatment
- Helps reduce hardness-related buildup
- Professionally installed
Drinking-Water TreatmentPortsmouth Reverse Osmosis
Reverse osmosis provides highly filtered water for drinking and cooking from a dedicated faucet, with refrigerator connection available where practical.
- Targets a broad range of dissolved contaminants
- Improves drinking-water taste and clarity
- Point-of-use treatment at the kitchen
Targeted FiltrationPortsmouth PFAS Water Filters
Compare specialized whole-home PFAS treatment with reverse osmosis for drinking-water treatment goals.
- Whole-home and point-of-use options
- Designed for targeted contaminant reduction
- System choice based on treatment goal
A Municipal Water Report Does Not Describe a Private Well
If your Portsmouth property is supplied by a private well, the city's 2025 municipal report does not tell you what is in that well. Private-well treatment should begin with the conditions at the property and any testing appropriate to the concern.
East Coast Water Quality can help homeowners evaluate private-well treatment options without treating city-water data as if it came from the well.
City water and well water need different starting points.
Municipal-water decisions can use the city's utility report as context. Private-well decisions should be based on the water at that specific property.

Portsmouth Water Treatment Questions
Where does Portsmouth, VA tap water come from?
The city's 2025 Water Quality Report identifies Lake Meade as the tap-water source, with influence from Lakes Cohoon and Kilby, Speight's Run Reservoir and five deep wells. The water is treated through Portsmouth's Lake Kilby Water Treatment Plant.
Is Portsmouth water hard?
The 2025 report lists hardness at 25 ppm, with a reported range of 18 to 36 ppm. That is about 1.5 grains per gallon at the reported amount detected. Whether a homeowner wants conditioning still depends on the water experience and treatment goal.
Does Portsmouth use chlorine or chloramine?
The 2025 city report lists chloramines as the disinfectant residual and reports an amount detected of 3.73 ppm.
Were PFAS detected in Portsmouth's 2025 Water Quality Report?
The report shows four samples for PFOA, PFOS, HFPO-DA, PFHxS, PFNA and PFBS. Every listed result was below the corresponding laboratory reporting or quantitation level shown in the table.
Why does EWG show concerns if the city report shows no listed 2025 contaminant violations?
EWG uses its own health-based guidelines, which are different from federal and state legal limits. A contaminant can be below a legal limit yet still exceed an EWG health guideline. The two types of benchmarks should be read separately.
What is the best water treatment system for a Portsmouth home?
It depends on the goal. Whole-home conditioning is used for hardness and related whole-house concerns, reverse osmosis is used for highly filtered drinking water, and specialized PFAS or private-well treatment should be selected for those specific needs.
Does a regular water softener remove PFAS?
No. A standard water softener is designed primarily to treat hardness minerals. PFAS concerns require treatment specifically designed and supported for PFAS reduction.
Can I schedule an in-home water test in Portsmouth?
Yes. East Coast Water Quality offers an in-home water evaluation for hardness and common aesthetic water conditions. It is not a certified laboratory analysis for PFAS, lead, arsenic, bacteria, nitrate or other laboratory-only contaminants.
