Laboratory reports of water from your well often include a measure known as specific conductance. This number indicates how well water carries an electrical current, which relates to the total amount of dissolved substances, including sediment, in the water. The U.S. Geological Survey collected 218 samples from 55 wells in Lake County’s aquifer 110DUNED between 2014 and 2023. These wells were shallow, ranging from 5 to 40 feet deep. All results showed specific conductance values from 16.0 to 11,200 uS/cm, with a median of 1155.0 uS/cm. These measurements help characterize the general water quality in the area—though they do not specify your well water’s exact condition.
If you consult public water system records instead of testing your own well water
Public system data offers a broad overview of water quality based on multiple wells distributed across an area. These records provide median values and ranges that reflect regional conditions but cannot establish the exact composition of a private residential well. Public sampling for Lake County’s aquifer 110DUNED found specific conductance always detected and never below reporting limits, demonstrating consistent dissolved solids presence but no health-based limit exceedances. Your own well’s sediment and dissolved solids content require direct testing to determine the appropriate treatment.
If your household plumbing shows signs linked to sediment presence
Common indicators of well pump sediment include cloudiness or grit in the water, increased wear on faucets and appliances, and clogged filters or screens. However, these symptoms alone do not confirm elevated dissolved solids or sediment concentration as indicated by specific conductance measurements. Other causes like organic debris or mineral scaling could produce similar effects. Confirming sediment as the source involves laboratory testing of your specific water supply.
If you want to manage sediment detected in your well water
The Pentair Sediment From the Well Pump Filter directly addresses particulate matter, removing sediment that can cause household plumbing issues. This system ships ready to configure and efficiently traps physical sediment, reducing the impact on your faucets and appliances. While it does not alter dissolved solids measured by specific conductance, it effectively handles the suspended particles contributing to sediment problems.
If your well depth or source type varies from the sampled range
The area data covers wells 5 to 40 feet deep, matching many shallow residential wells. Deeper wells may experience different water chemistry and sediment challenges due to varying geological formations. Shallow wells often have higher sediment loads influenced by surface runoff and aquifer characteristics. Understanding your well’s depth helps anticipate sediment levels and guides the selection of treatment options like sediment filters compatible with the Pentair system.
If you operate a commercial or industrial property instead of a household
Commercial and industrial water users face additional sediment management concerns such as higher water usage, equipment sensitivity, and regulatory compliance. These settings may require larger capacity or multiple treatment stages beyond residential needs. While this page focuses on household sediment issues in Lake County, commercial operators should consider these factors in consultation with specialized resources.
If you want to understand terms from the sampling record such as 'detected,' 'median,' and 'range'
- Detected means the constituent was measurable by the instruments used; it does not imply an unsafe or problematic level.
- Median is the middle value of all measurements, providing an indication of typical levels in the sampled wells.
- Range shows the lowest and highest values recorded, illustrating variability across the sampled wells.
For Lake County’s aquifer 110DUNED, all sampled wells showed specific conductance well below any federal health-based limit, indicating no regulatory exceedances were found.
For residential well owners in Lake County facing sediment issues, direct water testing is essential to guide treatment decisions. Based on this, the Pentair Sediment From the Well Pump Filter provides an established solution stocked and ready to ship for managing sediment particles effectively in household water systems.
