Background on Lenoir County’s Aquifer 211CPFRU

Water in Lenoir County often comes from wells tapping into aquifer 211CPFRU. This groundwater moves through rock and soil layers before reaching household taps. Government samples from this aquifer provide a regional perspective but don’t represent any single well’s conditions.

Number of Samples and Wells Behind the Copper Data

Three separate wells sampled across Lenoir County

Sampling involved three wells located between 25 and 448 feet deep.

A total of five copper tests conducted from 2013 to 2023

Five copper concentration measurements were collected over ten years.

Detected copper found in three of the five results

Copper was detected in three samples; two were below reporting limits but included in the dataset.

Small sample size means data is regional, not definitive for individual households

Since only a few wells and samples are represented, individual water tests are essential to know the copper level at your tap.

Maintenance Rhythm of the Pentair Blue-Green Copper Stains Filter

Ships ready to configure without professional help

The Pentair Blue-Green Copper Stains Filter is designed for direct purchase and arrives ready to configure.

Simple periodic filter cartridge replacement

Maintaining this system mainly requires changing filter cartridges according to the use frequency outlined in the product guide.

No routine chemical additives or complex upkeep needed

Its operation involves physical filtration, avoiding the need for ongoing chemical treatments.

Seasonal and Multi-Year Variation in Copper Levels

Range of copper concentrations from 0.75 to 12.4 micrograms per liter

The measured copper levels in the aquifer showed variation but remained below federal thresholds throughout the sampled period.

No clear upward or downward trend over ten years

The data does not indicate a steady increase or decrease in copper concentrations at these wells.

Variability reflects local hydrogeology and sampling conditions

Fluctuations in copper levels are expected in groundwater due to natural factors and seasonal changes in water flow or chemistry.

Order of Steps to Identify and Rule Out Copper Stains

Check visible signs of staining on fixtures and laundry

The first step is to observe areas where blue-green discoloration appears, which can suggest copper presence.

Test water for pH and other common staining contributors

Since copper stains correlate with water chemistry, testing pH and other constituents helps narrow causes.

Obtain a certified water test specifically measuring copper concentration

A laboratory test of your water supply confirms the copper content and informs treatment needs.

Evaluate plumbing materials and corrosion potential

Copper stains often result from corrosion of copper pipes; assessing household plumbing helps identify sources.

How Treated Water Changes at the Tap with the Pentair Filter

Reduces dissolved copper levels that cause staining

The filter physically removes copper, improving water clarity and reducing blue-green stains on surfaces.

Improves water appearance without altering taste or odor

By targeting copper alone, this system maintains the water’s overall character.

Requires no chemicals, preserving water safety

The treatment method avoids introducing additives or changing mineral balances.

Consequences of Leaving Copper Stains Untreated Over Years

Persistent staining on sinks, fixtures, and laundry

Untreated copper deposits build up and cause blue-green discoloration that can be difficult to remove.

Possible corrosion damage in copper plumbing

Ongoing copper presence may indicate pipe corrosion, which can shorten plumbing life and contribute to leaks.

Reduced aesthetic enjoyment of water and home appearance

Visible stains detract from household comfort and may affect resale value.

Summary of the Government Water Sampling Record

The U.S. Geological Survey collected five copper samples from three wells in Lenoir County’s aquifer 211CPFRU between 2013 and 2023. Detected copper levels ranged from 0.75 to 12.4 micrograms per liter, all below federal thresholds. This record reflects regional conditions only. For your household, a certified copper water test is needed to determine specific concentrations and copper-related issues. More details are available from the U.S. Geological Survey groundwater data source for aquifer 211CPFRU in Lenoir County.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2023-12-12. 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 211CPFRU aquifer (Lenoir County): 5 results from 3 wells, median 1.4 ug/L, range 0.75-12.4 ug/L; none above any federal threshold
