A laboratory test report for specific conductance shows how well water conducts electricity, measured in microsiemens per centimeter (µS/cm). This is an indicator of dissolved solids that can be associated with sediment presence. For Berkeley County, SC, the U.S. Geological Survey collected 16 samples from seven wells in the 120FLRD aquifer between 2011 and 2018. Results showed specific conductance values ranging from 109.0 to 2310.0 µS/cm, with a median of 451.5 µS/cm. None of these results exceeded any federal safety thresholds.
Which fixtures, appliances or processes are affected first and why?
Well pump sediment can first impact fixtures and appliances that have small openings or mechanical parts, such as faucets with aerators, household water filters, ice makers, and washing machines. Sediment can clog these parts, reducing flow and causing wear. Additionally, sediment can collect in pressure tanks and valves, causing irregular pressure and noise. Identifying where sediment-related issues appear helps focus attention on potential sediment presence in your water.
The order in which to rule things out, from cheapest check to laboratory test
Begin with simple observations and inexpensive checks before considering laboratory testing:
- Inspect faucet aerators and showerheads for visible particles or reduced water flow.
- Note any recent work on plumbing that might have disturbed sediments.
- Check if multiple fixtures show similar sediment evidence, indicating a source beyond a single outlet.
- If sediment persists, collect a water sample from your well and have it tested specifically for turbidity and sediment concentration at a certified lab.
Why aesthetic secondary standards differ from health-based limits, applied to this constituent
Specific conductance serves as a proxy for dissolved solids that can influence water taste, color, and corrosivity. The Environmental Protection Agency (EPA) sets secondary standards to maintain water appearance and infrastructure integrity, but these are not health-based limits. Exceeding a secondary aesthetic level does not mean the water is unsafe to drink. In Berkeley County, all sampled wells were below federal health limits, though some specific conductance levels were above typical aesthetic benchmarks, which might contribute to visible or taste changes.
How public-system records differ from private-well testing in what they establish
Public water supply records reflect testing results from many wells or sources over time and indicate area-wide trends but cannot specify conditions in any individual household well. The data for Berkeley County wells show general ranges and medians for specific conductance in the 120FLRD aquifer but do not determine the exact sediment level in your well water. To understand your household’s water condition, direct testing of your own well is necessary.
How the documented treatment technology removes or neutralises the constituent
The Fleck Sediment From the Well Pump Filter system ships ready to configure and is designed to remove sediment particles, including those that contribute to higher specific conductance measures related to dissolved solids. By filtering out sediment at the pump, this system helps protect household plumbing and appliances from sediment buildup and potential damage, improving water clarity and flow.
What questions a commercial or industrial operator adds that a household does not
Commercial and industrial water users must consider additional factors such as sediment impact on process equipment, potential scaling in boilers or cooling towers, compliance with industry-specific water quality standards, and cost implications of sediment-related maintenance downtime. These operators often require more frequent testing and tailored filtration solutions beyond residential needs.
If you detect sediment-related issues and have measured your household water's specific conductance, the Fleck Sediment From the Well Pump Filter system offers a direct-purchase option to address these concerns effectively based on your demand conditions.

Source: USGS groundwater sampling. Sampled 2018-08-30. 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.
