Government groundwater sampling in Clay County’s aquifer 111ALVM shows iron was detected in all 50 samples from 9 wells between 2010 and 2026, with concentrations ranging from 1,280 to 32,000 micrograms per liter, none exceeding federal safety thresholds.

What changes for a large household, a second home, or a seasonal property

Larger water use demands higher treatment capacity

Households with greater daily water use need treatment systems designed to handle increased volumes without loss of effectiveness.

Varying usage patterns affect treatment performance

Properties used intermittently, such as seasonal homes, may require adjustments to treatment schedules and maintenance to prevent issues from stagnation.

Multiple users may amplify water quality symptoms

In homes with many occupants, signs of water quality issues like staining or discoloration may become more noticeable due to cumulative effects.

How the constituent enters groundwater or the distribution system in this region

Natural iron deposits in aquifer materials

Iron occurs naturally in the clay and rock formations of Clay County’s aquifer 111ALVM and dissolves into groundwater over time.

Iron mobilization influenced by well depth and oxygen levels

Iron levels can vary with well depth, here between 36 and 105 feet, and with changing oxygen conditions underground that affect iron’s chemical form.

No indication of contamination sources in sampled wells

Sampling records do not show contamination events; iron presence is typical for the area’s geology.

The order in which to rule things out, from cheapest check to laboratory test

Check visible signs at water outlets

Look for discoloration, staining, or metallic taste which may signal elevated iron or related issues.

Test water with home iron test kits

Affordable kits can provide a preliminary sense of iron levels but have limits on accuracy and detection range.

Obtain certified laboratory testing of your well water

Only a lab test from your own well can confirm exact iron concentration and other constituents relevant to treatment decisions.

What happens when this problem is left untreated for years, stated without exaggeration

Metallic staining of fixtures and laundry

Iron in water can cause rust-colored stains on sinks, tubs, and fabrics over time.

Possible buildup in plumbing pipes

Iron deposits can accumulate and reduce pipe flow or cause discoloration in water supply.

Water taste and clarity changes

Elevated iron may affect water’s taste and appearance, potentially causing consumer concern even though levels are within safety limits.

How the documented treatment technology removes or neutralises the constituent

Fleck Complete Well System’s 32,000 grain capacity

This system is designed to handle high iron loads based on area median and range values, providing effective treatment for typical Clay County aquifer conditions.

Oxidation and filtration stages

The system converts dissolved iron to a solid form and filters it out, improving water clarity and reducing staining potential.

Automated regeneration cycles

Regular regeneration maintains treatment media effectiveness, ensuring consistent performance for household needs including large or seasonal use patterns.

Important: Area sampling results represent multiple wells and do not provide information about your specific well water. Testing your own water is necessary to determine the appropriate treatment approach.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2026-05-12. 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 111ALVM aquifer (Clay County): 50 results from 9 wells, median 12950.0 ug/L, range 1280.0-32000.0 ug/L; none above any federal threshold
