Number of Samples and Wells Behind Lafayette Parish Iron Data

The U.S. Geological Survey collected 56 iron measurements from 31 separate wells in Lafayette Parish’s aquifer 112CHCTU over a ten-year period from March 2011 to July 2021. These wells ranged in depth from 11 to 250 feet. This dataset provides a regional perspective, but the sample size, while meaningful, is limited in coverage. It reflects a broad average rather than specific details about any individual household water supply.

Because only a portion of wells in the parish were tested, the data reveal general iron presence and variation in the aquifer but cannot definitively characterize one home’s water. Testing your own well water is necessary for precise information.

Plumbing Material and Age Versus Source Water Iron Presence

Iron concentrations measured in these wells stem from the natural groundwater source rather than plumbing materials. However, older plumbing systems or certain pipe materials can influence how iron manifests in household water supply, sometimes contributing to staining or slime buildup independent of aquifer concentrations.

Understanding whether discoloration or slime originates from source water iron bacteria or aging plumbing components requires separate water testing and inspection of household pipes.

Fixtures, Appliances, and Water Uses Most Affected First

In homes drawing from aquifer 112CHCTU, faucets, showerheads, and appliances like washing machines and dishwashers tend to show iron bacteria effects first. These effects include reddish or brown staining and slime accumulation that can cause clogging or odor, potentially impacting appliance efficiency and lifespan.

Areas with frequent water exposure or slower flow rates are especially vulnerable to buildup and microbial growth related to iron bacteria.

Distinguishing Iron Bacteria from Iron and Other Similar Water Issues

Iron bacteria is different from simple dissolved iron in that it involves microbial activity producing slime and odors, whereas dissolved iron alone generally causes discoloration without slime. Iron bacteria can be mistaken for manganese or sediment issues; however, manganese does not produce microbial slime, and sediment is particulate matter rather than biological growth.

Tests focused on both microbial presence and iron concentration help differentiate iron bacteria from these other common water concerns.

Additional Considerations for Commercial or Industrial Water Use

Compared to residential settings, commercial or industrial operators consider factors like system volume, flow rates, and regulatory compliance that do not typically apply at home. They may require more comprehensive testing and treatment approaches to manage iron bacteria due to larger scale and varied water applications.

Homeowners can focus primarily on localized water quality and visible effects, whereas commercial entities must plan for broader impacts on equipment and processes.

What the Iron Range Means Against Federal Standards and What It Does Not

The iron concentrations detected in Lafayette Parish aquifer 112CHCTU ranged from 3.5 to 2670.0 micrograms per liter, with a median of 32.8 micrograms per liter, according to USGS data. None of these measurements exceeded any federal iron standards, which means the levels found are not violations or health risks by federal benchmarks.

High iron readings may cause aesthetic issues such as staining or taste concerns, but detection alone does not indicate unsafe water. Confirming your household water quality requires testing your own supply.

Summary of Lafayette Parish Iron Bacteria Sampling and Next Steps

The government sampling record covers 31 wells across Lafayette Parish’s aquifer 112CHCTU, providing insight into typical iron levels and variability in this region’s groundwater. While it does not establish conditions for any specific well or household, it helps to understand the local groundwater context.

For homeowners seeking to address iron bacteria and its effects, the Fleck Iron Bacteria & Slime Filter ships ready to configure and is designed to reduce bacterial slime and iron-related problems. Testing your own water remains essential to determine the best approach.

Source: USGS groundwater sampling. Sampled 2021-07-22. 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 112CHCTU aquifer (Lafayette Parish): 56 results from 31 wells, median 32.8 ug/L, range 3.5-2670.0 ug/L; none above any federal threshold
