How many samples and wells stand behind the figures, and what a small sample means
Number of Wells Sampled
The U.S. Geological Survey collected 51 groundwater samples from 48 different wells in Van Buren County, Arkansas, specifically within aquifer 328BLYD, between July 2011 and July 2015.
Sample Depth Consistency
These wells were sampled at depths ranging from 120 to 120 feet, helping create a consistent data set for the area aquifer's conditions during that time.
Limitations of Area Sampling
The data represents area-level observations and cannot specify the levels or presence of any constituents in your individual household well water. Individual testing remains necessary to know your well's exact condition.
How the constituent enters groundwater or the distribution system in this region
Sources of Constituents in Van Buren County Aquifers
Groundwater constituents measured in Van Buren County wells can come from natural deposits in soil and rock formations that the aquifer passes through. The measured constituent, iron, typically enters the groundwater through natural mineral dissolution.
Factors Influencing Constituent Presence
Variations in geology, well depth, and groundwater flow cause fluctuations in constituent levels. The sampled wells show iron ranging from undetectable to 1660.0 micrograms per liter, reflecting these natural variations.
Why aesthetic secondary standards differ from health-based limits, applied to this constituent
Aesthetic Standards vs. Health-Based Limits
Iron is governed by aesthetic secondary standards designed to address taste, staining, and discoloration rather than health risks. In the Van Buren County data set, no iron results exceeded any federal health-based limits.
Understanding Detection and Its Meaning
Detection of iron in water samples indicates measurement by instruments but does not imply contamination or health concerns. Concentrations below a certain threshold primarily affect appearance and household appliance longevity.
The order in which to rule things out, from cheapest check to laboratory test
Checking Household Equipment Performance
If existing water treatment equipment cannot keep up with total well water needs, start by verifying that filters and media are operating within their expected capacity and replacement intervals.
Conducting a Certified Laboratory Test
To identify specific constituent levels including iron in your household water, obtain a certified lab test. This definitive step clarifies treatment needs and informs effective solutions.
Assessing Water Quality Over Time
Regular monitoring helps detect changes in constituent levels or treatment effectiveness, guiding adjustments or enhancements to maintain water quality.
The role of plumbing material and age, separate from the source water
Impact of Plumbing on Water Quality
The materials and age of household plumbing can influence water appearance, taste, and staining apart from source water quality. Components such as old pipes may contribute to discoloration or sediment.
Distinguishing Source vs. Plumbing Issues
Isolating water treatment challenges caused by plumbing requires targeted inspection, as treatment systems focus on source water conditioning rather than plumbing repairs.
In summary, the groundwater sampling data from 48 wells across Van Buren County’s aquifer 328BLYD provide a baseline for understanding typical constituent ranges including iron. No results exceeded federal health-based thresholds, and the data do not reflect individual well conditions. For personalized treatment needs, certified lab testing is essential. The Fleck Total Well Chlorination System ships ready to configure and offers a documented solution for households whose current equipment cannot meet total well water treatment demands.

Where this information comes from
Source: USGS groundwater sampling. Sampled 2015-07-13. 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 328BLYD aquifer (Van Buren County): 51 results from 48 wells, median 0.0 ug/L, range 0.0-1660.0 ug/L; none above any federal threshold
