Reading Copper Sampling Data for Saunders County's Aquifer 110SAGR
Median Copper Levels Found in Local Wells
Government sampling from Saunders County's 110SAGR aquifer recorded a median copper concentration of 1.5 micrograms per liter (ug/L) from three samples taken between August 2021 and April 2023.
Range of Copper Concentrations Measured
The copper levels in sampled wells ranged from 1.1 to 2.5 ug/L, indicating some variation in the aquifer over this timeframe.
No Federal Thresholds Exceeded
None of the recorded copper levels in these samples exceeded any federal copper concentration thresholds applicable to drinking water quality.
Fixtures and Household Elements First Affected by Copper Stains
Visible Stains on Bathroom and Kitchen Sinks
Copper stains often appear as blue-green discoloration around faucets and sink basins where water contact is frequent.
Appliances Using Water for Heating and Cooling
Items like water heaters or coffee makers may show mineral deposits related to copper presence over time.
Bathroom Fixtures with Metal Drain Covers or Tub Surfaces
Repeated water contact can cause gradual staining or discoloration in tubs or on drain surfaces.
Seasonal and Multi-Year Variation Shown in Sampling Dates and Range
Sampling Spanned From Late Summer 2021 to Early Spring 2023
Data includes three samples taken over approximately 20 months, revealing some fluctuation in copper levels within the aquifer.
Moderate Variation Without Exceedance of Limits
While copper levels varied between samples, all remained well below concern thresholds, showing no clear pattern of increasing contamination.
Potential Influence of Seasonal Water Table Changes
Variations may relate to changes in groundwater levels or flow patterns but require further local testing to confirm.
Understanding Certified Laboratory Copper Testing and Result Interpretation
Testing Requires a Certified Water Sample
To determine your home's water copper concentration, a certified laboratory must analyze a properly collected sample.
Result Reports Include Concentration in Micrograms per Liter
Reports detail copper levels usually expressed as ug/L, useful for comparison against regional data and regulatory thresholds.
Consulting Laboratory Reports Helps Guide Treatment Decisions
Results clarify whether copper is contributing to household staining and if specialized filtration could improve water appearance.
The Effect of Plumbing Materials and Age Apart from Source Water Copper
Older Copper Plumbing May Release Additional Copper Into Water
The presence of copper stains may partly result from corrosion or leaching in household pipes independent of aquifer concentrations.
Plastic or PEX Piping Typically Does Not Contribute Copper
Homes with non-metal piping materials often experience fewer copper-related stains despite aquifer copper levels.
Water Chemistry and pH Can Influence Copper Dissolution From Pipes
Factors like acidity or water hardness impact how much copper is released from plumbing surfaces into water.
What Saunders County Aquifer Copper Data Does Not Say
The government sampling data reflects area aquifer copper concentrations only and does not measure individual home water quality.
Detection of copper in area wells does not mean your home's water has the same levels or that staining will necessarily occur.
Testing your water through a certified laboratory is the only way to confirm specific copper concentrations for your household.
For homes where copper stains continue despite existing measures, the C-Series Blue-Green Copper Stains Filter ships ready to configure as a documented water treatment option to address staining issues.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2023-04-19. 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.
