What to Record Before Asking for Treatment Advice

Note your water source type and well depth if applicable

Knowing whether your water comes from a private well or a public supply helps clarify what data apply to your situation. The USGS samples wells ranging from 29 to 250 feet in Hillsborough County's 120FLRD aquifer, so recording your own well’s depth or source can guide interpretation.

Track visible copper staining and affected fixtures

Identify where copper stains appear—such as sinks, faucets, laundry areas, or dishware—to target treatment efforts effectively.

Obtain your own water test results for copper content

Government area data show general conditions but do not specify your well or tap water content. A current test of your water's copper concentration is essential to understand your home's specific situation.

Why Secondary Aesthetic Standards Differ from Health-Based Limits for Copper

Copper staining relates to concentrations affecting taste, color, and surface appearance

Regulatory secondary standards focus on preventing issues like staining and metallic taste, rather than health risks. The USGS data for Hillsborough County found copper detected in a minority of samples but always below thresholds for health concerns.

Detected copper does not imply safety risk

Measurements between 0.55 and 3.4 micrograms per liter were noted in some wells, but none exceeded federal limits. These levels are typical and do not indicate unsafe water.

How Seasonal or Multi-Year Variation Shows in the Record

Sampling spanned nearly two years from 2011 to 2012

Results reflect multiple time points across seasons, supporting a stable range of copper presence in local groundwater.

Range and median figures offer perspective on fluctuations

The median copper concentration was 1.0 µg/L, with individual results varying modestly. This suggests no large seasonal spikes in copper levels during the sampled period.

How Many Samples and Wells Stand Behind the Figures

Data represent 17 samples from 13 unique wells

This coverage across multiple wells provides a broader regional picture but remains limited relative to the full aquifer area.

Small sample size means local variation is possible

Your home’s water may vary from area medians depending on local geology, well depth, and plumbing materials.

How Public-System Records Differ from Private-Well Testing

Public water suppliers routinely test for copper and report regulatory compliance

For municipal water users, records generally show copper levels well below health-based limits. Such data confirm the system meets safety requirements.

Private wells require individual testing to assess copper staining risk

The USGS data do not replace testing of your specific well water, which determines exact copper presence driving stains in your household.

How the Documented Treatment Technology Addresses Copper Stains

The Autotrol Blue-Green Copper Stains Filter ships ready to configure for home use

This system reduces copper-related staining by treating water to prevent deposits on fixtures and fabrics, improving appearance and maintenance.

Technology focuses on minimizing copper's aesthetic effects

The filter targets the dissolved copper that can cause blue-green stains, helping households manage this specific nuisance without altering water safety or mineral content significantly.

Closing Notes

Area groundwater copper data from Hillsborough County’s 120FLRD aquifer provide useful context but do not determine your home’s water quality. Copper detections in regional sampling are typical and below federal health limits, so do not assume a safety issue. Personal water testing remains essential to guide your choice between treatment options addressing copper stains.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2012-11-07. 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 Copper in the 120FLRD aquifer (Hillsborough County): 17 results from 13 wells, median 1.0 ug/L, range 0.55-3.4 ug/L; none above any federal threshold
