Government groundwater sampling in Sullivan County’s aquifer 112SDGV shows copper presence in all five tests from two wells, with concentrations ranging from 1.0 to 101.0 micrograms per liter (ug/L) and a median value near 25.5 ug/L. None of these measurements exceed federal copper thresholds. This data reflects area-wide conditions from wells 42 to 90 feet deep and does not represent your individual household water quality.
If You Are a Commercial or Industrial Operator
Commercial or industrial users typically face larger water volumes and more complex process demands than households. Their treatment systems need to factor in higher flow rates and possible regulatory reporting. In contrast, a household's daily water demand is smaller and focused on aesthetic and fixture maintenance concerns.
If You Are Estimating Treatment Capacity for a Household
To decide on an effective approach against copper stains, consider your household’s average daily water use. Treatment equipment must handle peak demand while effectively reducing copper-related staining. Estimating gallons per day helps select a filter system sized for your usage rather than using generic capacity assumptions.
If You Want to Understand What the Measured Copper Range Means
The recorded range of copper concentrations in this aquifer shows detectable copper in all sampled wells. However, none of the results surpass the federal action level for copper in drinking water. Detection does not imply a violation or health risk. Instead, it indicates copper is present at concentrations where staining can occur on fixtures and surfaces over time.
If You Are Considering the Number of Samples and Wells Behind These Figures
The data comes from five samples collected across two separate wells over multiple years. While this provides an area-wide perspective on copper levels, the limited number of wells and samples means individual household water quality could vary. Testing your own water is essential to determine your specific copper concentration and staining potential.
If You Want to Understand Seasonal or Multi-Year Variation in the Records
Samples were taken between October 2010 and August 2020, indicating stable detection of copper over nearly a decade. The range in copper levels suggests natural fluctuations or varying well depths and conditions. Such variability emphasizes the importance of up-to-date, localized water testing for current household decisions.
For addressing copper stains aligned with your household’s daily water demand, the Fleck Blue-Green Copper Stains Filter provides a ready-to-configure solution. It is designed specifically to reduce copper staining issues based on measured use and water characteristics, helping protect your home’s fixtures effectively.
