Opening: Distinguishing Area Data from Your Well's Specific Condition
Government groundwater sampling from McLean County's aquifer 110QRNR provides valuable information about the general water quality in the area but does not substitute for individual well testing. While samples show chloride presence across several wells, this data cannot determine the exact characteristics of your home's water supply or the current state of your existing treatment equipment.
1. How the Documented Treatment Technology Removes or Neutralizes Chloride
The C-Series Total Well Chlorination System is designed to address constituents commonly found in well water, including chloride's associated effects. Although chloride itself is not removed by chlorination, the system uses a chemical treatment process that helps control bacterial presence and oxidation reactions that may be linked to chloride-related water issues. The system combines a grain capacity of 32,000 to manage water treatment load effectively, making it suitable for residential settings facing equipment failure.
2. Household Symptoms That May and May Not Indicate This Problem
Symptoms like unusual taste or minor staining on fixtures can sometimes be related to elevated chloride or total dissolved solids levels, but such observations alone do not confirm the problem since chloride detections in local wells have never exceeded federal thresholds. Conversely, problems like strong odors or visible sediment typically arise from different causes unrelated to chloride levels documented in this region.
3. Understanding What a Certified Laboratory Test Reports and How to Read It
A certified lab test for chloride will report concentration levels in milligrams per liter (mg/L). In McLean County's 110QRNR aquifer, government samples ranged from 4.03 to 108.0 mg/L, with a median of 22.1 mg/L. These figures represent measurements from eleven wells sampled multiple times over several years but do not establish a safety or violation threshold for your well. Your own test results need to be interpreted in the context of federal aesthetic secondary standards, which relate mainly to taste and corrosion potential rather than health risks.
4. How Chloride Enters Groundwater in This Region
In McLean County, chloride arrives naturally or through human-related sources such as road salt and agricultural runoff. Because sampled wells ranged in depth from 12 to 320 feet, chloride concentrations can vary depending on well depth and surrounding land use. Understanding these factors in your well's context is essential for identifying the appropriate treatment needs.
5. The Number of Samples and Wells That Inform These Figures and the Implications of a Small Sample Size
The chloride data is based on 51 samples collected from 11 distinct wells over a period from 2010 to 2018. While this provides a reasonably robust snapshot of regional water quality, this sample size is limited relative to the number of private wells in the area. Therefore, the figures serve as useful background information but cannot replace testing your own water source to tailor treatment efforts effectively.
6. The Meaning of Terms 'Detected', 'Median', and 'Range' in This Sampling Record
'Detected' indicates that chloride was found in every one of the 51 samples, meaning the constituent is commonly present in the aquifer. The 'median' value of 22.1 mg/L reflects the middle point of all measured concentrations, while the 'range' from 4.03 to 108.0 mg/L shows the span between the lowest and highest sample results. None of these measurements exceeded federal limits, confirming no regulatory concern but highlighting variability you should consider for your well water treatment.
Closing
The sampling record covers multiple wells across McLean County's 110QRNR aquifer and provides regional chloride data collected over eight years. For detailed water quality specific to your home, a certified laboratory test is necessary. These government figures and the documented capabilities of the C-Series Total Well Chlorination System offer a foundation for understanding and addressing treatment needs. For reference, see the U.S. Geological Survey groundwater sampling data at their official website.

Source: USGS groundwater sampling. Sampled 2018-08-01. 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.
