What 'Detected', 'Median', and 'Range' Mean in Marquette County Sampling

Detected Means Copper Was Measured

Government sampling in Marquette County’s aquifer code 112SDGV found copper in all three tested results from two wells. Detection simply means instruments measured copper; it does not indicate a violation or unsafe level.

Median Shows the Middle Value of Measurements

The median copper concentration recorded was 4.2 micrograms per liter (ug/L), meaning half the results were above and half below this value. This summarizes the area’s typical copper presence.

Range Indicates Variation Across Samples

Results ranged from 2.9 to 4.5 ug/L, demonstrating some variation between wells and times sampled but all measurements remained well below any federal concern thresholds.

What to Write Down Before Discussing Treatment Options

Know Your Own Water Test Results

Local area data does not replace a test of your home's water. Obtain a certified laboratory analysis of your water’s copper level to understand your specific conditions.

Record Your Existing Treatment Details

List the type and capacity of your current equipment, noting any issues like copper-based stains that may indicate performance limits.

Note Your Water Usage Patterns

Tracking daily water use helps align treatment capacity with your household’s demand to address stain problems effectively.

How the Fleck Blue-Green Copper Stains Filter Addresses the Issue

Removes Copper Through Specialized Filtration

This system uses technology designed to reduce copper concentrations that contribute to blue-green stains on plumbing and fixtures, helping maintain cleaner surfaces.

Ships Ready to Configure for Residential Use

The Fleck system is designed for direct purchase by homeowners seeking to enhance their current setup’s capability to handle ongoing copper-related staining.

Understanding Certified Laboratory Copper Test Reports

Reports Provide Measured Copper Concentrations

A lab report lists copper levels in micrograms per liter or parts per billion, allowing you to compare your water with area sampling values to gauge stain risk.

Interpretation Requires Considering Local Background Levels

Comparing your concentration to Marquette County’s aquifer 112SDGV median and range can clarify whether your water has typical copper levels or requires treatment.

Seasonal and Multi-Year Variation in Marquette County Copper Levels

Samples Taken Over an 11-Year Span

The three copper measurements span from July 23, 2013, to August 21, 2024, showing stable detection in this period without extreme fluctuations.

Depth of Sampled Wells Provides Consistency

Wells were between 41 and 67 feet deep, offering a representative view of groundwater copper levels across this part of Marquette County.

This summary is based on government sampling of Marquette County’s aquifer 112SDGV from two wells over 2013-2024. Source data can be found at the U.S. Geological Survey groundwater monitoring website.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2024-08-21. 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.
