Iron Bacteria in Tooele County Homes: Understanding Area Water Data and Equipment Limits

Laboratory Test Reports for Iron in Residential Water

Reported Results Show Iron Amounts as Micrograms per Liter

A water test report lists iron concentration as micrograms per liter (ug/L). It includes a detection status, a numeric value if detected, or a note if below the reporting limit. This confirms iron's presence but not its exact effect or severity.

Household vs. Commercial/Industrial Operators’ Additional Questions

Households Focus on Appearance and Equipment Impact

Residential users mainly track iron bacteria effects on plumbing, staining, and water clarity rather than detailed chemical breakdown or regulatory compliance.

Commercial Users Consider Regulatory Compliance and Process Stability

Operators in commercial or industrial settings also assess iron bacteria growth’s impact on production cycles, equipment downtime, and wastewater discharge permits.

Understanding Sample Data Terms: Detected, Median, and Range

Detected Means Iron Was Measured, Not That It’s a Problem

Of 97 samples from Tooele County’s aquifer 100VLFL wells, iron was detected in 41 results. Detection confirms presence but not exceedance or hazard.

Median Represents the Middle Value Among All Measures

The median iron concentration in area sampling was 9.6 ug/L, meaning half were above and half below this level among positive detections.

Range Shows Lowest and Highest Measurements Recorded

Range in the area's samples stretched from 3.3 to 2180.0 ug/L. Depths of tested wells varied from 43 to 732 feet.

Measured Iron Levels vs. Federal Standards: What Does This Mean?

No Area Sample Exceeded Federal Limits for Iron

All recorded iron levels in sampled wells were below federal secondary standards, which focus on aesthetic factors like taste and staining, not health risks.

Measuring Iron Level Alone Does Not Confirm Equipment Needs

Individual well testing is necessary to determine if existing water treatment can handle iron bacteria effects or if additional solutions are needed.

First Household Fixtures and Appliances Affected by Iron Bacteria

Water Softeners and Filters May Experience Increased Load

Iron bacteria can create slime build-up that clogs or hinders filtration media, causing existing equipment to struggle over time.

Fixtures May Show Staining and Reduced Flow

Visible reddish-brown stains on sinks, tubs, or toilets often indicate iron presence combined with bacteria causing slime deposits.

Comparing Iron Data: Tooele County vs. Neighboring Areas

Sampling Scope and Geological Differences Affect Results

Iron concentration varies with aquifer composition and well depths; neighboring counties may show different median and range values reflecting their geology.

Use Area Data as a Contextual Guide, Not a Definitive Measure

Regional statistics inform likely water characteristics but should not replace direct well testing for exact treatment planning.

Summary

Tooele County aquifer samples show iron bacteria present at levels below federal secondary standards, so detection alone does not signal a health risk or immediate violation. Households with existing but stressed equipment may benefit from a direct-purchase Autotrol Iron Bacteria & Slime Filter, which ships ready to configure and can supplement current systems to manage iron bacteria challenges effectively.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2021-06-15. 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 100VLFL aquifer (Tooele County): 97 results from 31 wells, median 9.6 ug/L, range 3.3-2180.0 ug/L; none above any federal threshold
