Gloucester Water Problems, Contaminants & Treatment Options
Compare Gloucester County's 2025 public-water results with EWG's separate health-guideline data, understand common concerns at the tap, and see which treatment approach fits the water goal you want to address at home.
What Is Reported in Gloucester Drinking Water?
Gloucester County Public Utilities' 2025 Annual Drinking Water Quality Report says the public water system had no violations during 2025. EWG uses separate, non-enforceable health guidelines and a different reporting period, so a substance can be below a legal limit while still appearing above an EWG guideline.
Regulatory Standards
The County report lists maximum contaminant levels, action levels, treatment techniques and other compliance measures used under federal and Virginia drinking-water rules.
Health Guidelines
EWG health guidelines are non-enforceable benchmarks. They are not the same as EPA or Virginia legal drinking-water limits.
Your Home
Utility-wide results do not tell you the exact condition at one faucet. Household plumbing can affect lead, copper, taste, odor and other experiences at the tap.
Meeting a legal standard and exceeding an EWG guideline are not contradictory.
Use Gloucester County's official report for regulatory compliance information. Use EWG as an additional health-guideline reference, while keeping its non-regulatory status and different reporting period in mind.
Contaminants Shown Above EWG Health Guidelines
EWG's current utility page for Gloucester County Water Treatment Plant lists 12 contaminants above EWG health guidelines. The database period shown by EWG is 2018–2023. These are EWG benchmarks, not EPA or Virginia legal limits.
Bromodichloromethane
Bromoform
Chloroform
Chromium (hexavalent)
Dibromoacetic acid
Dibromochloromethane
Dichloroacetic acid
Haloacetic acids (HAA5)
Haloacetic acids (HAA9)
Radium, combined (-226 & -228)
Total trihalomethanes (TTHMs)
Trichloroacetic acid
About the numbers: EWG's database and Gloucester County's 2025 Annual Drinking Water Quality Report do not summarize the same samples or reporting period. Do not compare their individual values as though they came from one test event.
Other Contaminants Listed for Gloucester
EWG currently lists seven additional detected contaminants for this utility that are not in its “exceed guidelines” group.
| Contaminant | Utility Value | EWG Guideline | Legal Limit Shown by EWG |
|---|---|---|---|
| Barium | 7.67 ppb | 700 ppb | 2,000 ppb |
| Fluoride | 0.0367 ppm | — | 4 ppm |
| Manganese | 0.502 ppb | 100 ppb | No legal limit shown |
| Monobromoacetic acid | 0.0625 ppb | 25 ppb | No legal limit shown |
| Monochloroacetic acid | 0.229 ppb | 53 ppb | No legal limit shown |
| Strontium | 0.0675 ppb | 1,500 ppb | No legal limit shown |
| Vanadium | 0.259 ppb | 21 ppb | No legal limit shown |
Current Public-Water Results and Characteristics
The newest official County report provides the regulatory and system-wide context for Gloucester public water.
Chloramines
The report lists a 2.75 mg/L annual average, with a reported sampling-point range of 0.6–3.9 mg/L and no violation.
Disinfection Byproducts
The report lists a highest locational running annual average of 58 ppb TTHM and 27 ppb HAA, below the MCLs shown in the report.
Lead
The latest lead and copper table reports a 2 ppb lead 90th percentile, a range of <1–22 ppb, and 1 site exceeding the 10 ppb action level shown in the report.
Sodium
The October 1, 2025 sample averaged 26.1 mg/L sodium. The County notes this exceeds the recommended 20 mg/L maximum for people on a strict sodium diet.
The 2025 report says Gloucester Public Utilities had no violations.
The report also explains that some contaminants are monitored less than once per year when concentrations do not change frequently, so not every result in the 2025 report comes from a 2025 sampling event.
Why Gloucester Water Can Taste, Smell or Behave Differently at the Tap
A utility report describes the public system. Your experience can also be influenced by distribution-system disinfectant, household plumbing, fixtures and water characteristics that are not quantified in the 2025 report.
Disinfectant Taste or Odor
Gloucester uses chloramines for longer-lasting distribution-system disinfection. Some households may choose carbon treatment when taste or odor is the main concern.
Scale or Spotting
The 2025 County report does not publish a finished-water hardness value, so hardness at a home should be measured rather than estimated from another utility or an older report.
Home Plumbing
Lead and copper can be influenced by service-line and household plumbing materials. That is why customer-tap sampling is different from treatment-plant monitoring.
PFAS and Lead Need Different Kinds of Context
Neither a broad utility summary nor a free in-home aesthetic water test should be treated as a property-specific laboratory result for PFAS or lead.
PFAS
Gloucester County's 2025 Annual Drinking Water Quality Report does not include a PFAS or UCMR results table. EWG's current Gloucester utility page also does not place PFAS among the 19 contaminants it lists as detected. That is not the same as a property-specific PFAS laboratory test.
Lead
The County's latest lead and copper table reports a 2 ppb lead result at the 90th percentile and one site above the 10 ppb action level shown in the report. Because plumbing materials vary by property, a specific home's lead level requires appropriate tap sampling and laboratory analysis.
Which Gloucester Water Treatment System Addresses Which Problem?
No single system is the best choice for every water concern. The correct treatment depends on the substance, whether you want to treat one drinking-water faucet or the whole home, and the exact performance claims of the selected model.
Read this matrix as a treatment guide—not a blanket removal guarantee.
Actual reduction depends on system configuration, media, membrane performance, flow rate, maintenance, water chemistry and certification. Confirm claims against the exact product specifications for the system selected.

The data above describes Gloucester County's public-water system, which blends treated Beaverdam Reservoir water with reverse-osmosis-treated deep groundwater. A private well can have completely different conditions and needs property-specific evaluation.
Gloucester Public Water
Use the County report and EWG utility page to understand the public system, then consider household plumbing and your treatment goals.
Private-Well Water
Iron, sulfur odor, sediment, hardness, pH, bacteria and other well conditions should be evaluated from the actual property's water rather than inferred from public-system data.
Use the Right Test for the Water Question
Different water concerns require different kinds of testing. A household evaluation can help with common aesthetic conditions, while specific contaminants require appropriate laboratory methods.
Common Household Conditions
ECWQ's free in-home evaluation can help assess hardness and other common aesthetic water conditions used for treatment planning.
PFAS or Lead
PFAS and lead require proper sample collection and laboratory analysis when a property-specific result is needed.
Private Wells
Well-water testing should be selected for the actual concern, especially when bacteria, metals or other health-related contaminants are involved.
Gloucester Water Problems FAQs
Did Gloucester County public water have violations in 2025?
No. Gloucester County's 2025 Annual Drinking Water Quality Report states that Gloucester Public Utilities had no violations during 2025.
Why does EWG show contaminants above health guidelines if the County reports no violations?
EWG uses separate, non-enforceable health guidelines that can be lower than federal or Virginia legal limits. The EWG database also covers a different reporting period than the County's 2025 report.
What contaminants does EWG list above its health guidelines for Gloucester?
EWG's current Gloucester County Water Treatment Plant page lists 12 contaminants above its health guidelines, including several disinfection byproducts, hexavalent chromium and combined radium. The detailed cards above show the utility values and EWG benchmarks.
Does Gloucester use chloramine?
Yes. Gloucester County reports that it began adding ammonia in 2017 to form chloramines for longer-lasting distribution-system disinfection.
Is Gloucester water hard?
The 2025 County report does not publish a finished-water hardness value. If scale, spotting or soap performance is a concern, hardness should be measured at the home rather than estimated from another utility's data.
What did the 2025 report say about lead?
The report lists a 2 ppb lead result at the 90th percentile, a sample range of less than 1 to 22 ppb, and one site exceeding the 10 ppb action level shown in the report. A specific home's lead level depends in part on its plumbing and requires appropriate tap testing.
Does the Gloucester 2025 report include PFAS results?
No PFAS or UCMR results table appears in the 2025 report. EWG's current utility page also does not list PFAS among its 19 detected contaminants.
Do these public-water results apply to a private well?
No. Private-well water can have different chemistry and should be evaluated using the actual property's water and appropriate testing.
