What information does a laboratory test report provide about total well water?

A laboratory test report for total well water typically lists the concentrations of various constituents measured in a well water sample. For example, testing for iron concentration is common since iron is often present in groundwater. The report will state the measured level of iron in micrograms per liter (ug/L) or milligrams per liter (mg/L), providing insight into the water’s quality for that sample. However, this reading reflects only the specific tested water and not the entire water supply or area.

How should a homeowner interpret McLean County aquifer iron data?

Government sampling by the U.S. Geological Survey in McLean County’s aquifer 110QRNR involved 50 samples from 10 different wells collected over several years (2010–2018). Iron was detected in 42 of these samples, with measured levels ranging from 3.9 to 2260 ug/L and a median value of 147 ug/L. This data means that iron can vary widely across the area’s wells and that concentrations below or near the median are common. It illustrates the variability residents might face but does not define an individual household’s water quality.

What does the measured iron range indicate relative to federal standards?

None of the samples in this McLean County study exceeded any federal health-based thresholds for iron. It is important to note that detection of iron is not a violation nor a safety concern by itself. Iron’s presence may influence aesthetic factors such as taste, color, and staining rather than health. Therefore, this range provides information on local water characteristics but does not imply that water in any particular well is unsafe or noncompliant.

What information should I record before seeking advice on water treatment?

Before making treatment decisions, gather the following about your water:

• Detailed laboratory test results for your specific well, including all detected constituents and their concentrations
• Date and location of your water sample collection
• Any observed household symptoms such as discoloration or staining
• Previous water treatment methods tried and their outcomes

Having this information ready helps in assessing treatment needs accurately rather than relying solely on area-wide data.

Which household symptoms suggest the need for total well water treatment?

Signs that may point to total well water concerns include reddish-brown stains on plumbing fixtures or laundry, metallic taste in drinking water, or water discoloration. These symptoms often result from constituents like iron. However, absence of these signs does not prove that treatment is unnecessary, and their presence does not confirm a specific level of iron or other substances without laboratory testing.

How does the Fleck Total Well Chlorination System address water quality issues?

The Fleck Total Well Chlorination System is designed to reduce or neutralize constituents commonly found in well water, including iron. This system ships ready to configure and works by introducing and controlling chlorine levels to oxidize iron, rendering it easier to remove. With a grain capacity of 32,000, it effectively handles typical household demands in areas like McLean County. This approach can improve water clarity and reduce staining issues associated with iron and similar minerals.

What should I not conclude from the McLean County area data?

Area water data from aquifer 110QRNR is a valuable resource but should not be assumed to represent any individual well's water quality. Detection of iron in some area wells does not establish the presence or concentration in your well. The absence of federal threshold exceedances in sampled wells indicates the general compliance of the area but does not guarantee your water’s exact condition. To determine appropriate treatment, testing your well water and documenting your specific situation remain essential steps.

Where this information comes from

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.

On record: U.S. Geological Survey sampling of Iron in the 110QRNR aquifer (McLean County): 50 results from 10 wells, median 147.0 ug/L, range 3.9-2260.0 ug/L; none above any federal threshold
