Overview of Virginia Beach City Aquifer and Water Delivery

The aquifer 121YKEV beneath Virginia Beach City supplies groundwater that household systems draw upon for daily use. Water is sourced from depths between approximately 100 to 300 feet where natural minerals like manganese naturally occur. This groundwater is then treated and delivered through private household setups to taps, where residents may notice issues such as metallic taste, often linked to mineral content.

Maintenance Rhythm of Fleck Metallic-Tasting Water Filter

Routine Filter Media Replacement

The Fleck Metallic-Tasting Water Filter includes media that gradually adsorbs manganese and other minerals contributing to metallic taste. Periodic replacement of this media, generally on a multi-month cycle, ensures continued effectiveness without the need for complex servicing.

System Backflush Schedule

This system operates with automated backflushing to cleanse the filter media of accumulated substances, typically scheduled weekly or biweekly depending on water usage, maintaining flow rates and filtration quality.

Component Inspection Intervals

Inspecting control valves and seals every few months helps identify wear and ensures consistent filter operation without interruption.

Seasonal and Multi-Year Variation in Water Quality Data

Manganese Levels Across Sampling Dates

Data from 2010 through 2023 monitoring 22 wells in Virginia Beach City's aquifer 121YKEV shows manganese concentrations ranging from 3.03 to 124.0 micrograms per liter, with a median value near 11.8 micrograms per liter.

Implications of Concentration Fluctuations

These variations reflect natural changes in groundwater chemistry over time and depth, influenced by factors such as rainfall, aquifer recharge, and mineral dissolution patterns, which can affect taste perception at the tap.

Comparison with Neighboring County’s Water Quality Record

Similar Aquifer Geology in Adjacent Areas

Neighboring counties often share related aquifer geologies but may show different manganese ranges due to local hydrological conditions, well depths, and sampling times.

Avoiding Overinterpretation of Differences

While manganese levels may be higher or lower in nearby counties, these differences do not predict individual household well water quality. Only direct testing of a home’s water can establish actual conditions.

Long-Term Consequences of Untreated Metallic Taste

Gradual Impact on Water Flavor

Without treatment, metallic taste can persist or intensify over time as manganese and other minerals accumulate, potentially leading to unpleasant drinking water experience.

Effects on Appliances and Plumbing

Prolonged exposure to mineral-rich water may contribute to staining or buildup on fixtures or appliances, though such effects vary by usage and water chemistry.

Additional Considerations for Household Water Use

Testing Your Own Water

Because area data cannot confirm individual conditions, residents are encouraged to obtain laboratory testing of their household water to measure manganese and other constituents accurately.

Choosing Appropriate Filtration

The Fleck Metallic-Tasting Water Filter ships ready to configure and is designed specifically to reduce manganese-related taste issues documented in this aquifer, restoring water palatability.

What Area Data Does Not Reveal

No Assurance of Individual Water Content

These regional manganese values do not predict any single household’s water quality; local plumbing, water source depth, and well condition all affect taste.

No Health Risk Indicated by Detected Manganese

All reported manganese levels in the area remain below federal health thresholds, so detection alone does not imply unsafe water.

Municipal Water Supply Records

Residents served by public systems should consult official water quality reports, but this data pertains solely to groundwater wells sampled within aquifer 121YKEV and does not apply to treated public water directly.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2023-08-23. These figures describe groundwater sampled in this area. They are not a test of any individual private well - only a test of that well can establish its own water.

On record: U.S. Geological Survey sampling of Manganese in the 121YKEV aquifer (Virginia Beach city County): 46 results from 22 wells, median 11.8 ug/L, range 3.03-124.0 ug/L; none above any federal threshold
