If you expect your household water selenium to be similar to Lafayette Parish aquifer 112CHCTU samples
The Lafayette Parish water supply often draws from aquifer 112CHCTU, where government groundwater monitoring has checked selenium levels. Sampling from 31 wells over 2011 to 2021 found selenium detected in many samples, with concentrations ranging from 0.03 to 5.6 micrograms per liter, and a median at 0.37 micrograms per liter. None exceeded federal safety thresholds, indicating the water source itself meets health-based federal standards for selenium. However, these figures reflect area conditions, not your household water specifically. Your exact water can only be known by testing your own well or tap.
The water reaching residential taps starts underground, filtered through soil and rock, then pumped to the surface. Variations in well depth (11 to 250 feet in the sampled data) and localized geology can cause differences in heavy metals content between homes. These area figures simply provide context for what is typical in Lafayette Parish’s aquifer 112CHCTU.
If you see changes in water taste, staining, or metallic odors
Some changes may relate to heavy metals, but are not definitive for selenium or other metals alone. Aesthetic secondary standards for minerals and dissolved solids affect how water tastes or stains fixtures but do not reflect health risks. Selenium levels in Lafayette Parish water generally stay below health limits, so taste or appearance shifts may stem from other water quality factors.
For larger households or seasonal residences, water use patterns can affect the system's flow rate and contact time with filtration components, potentially influencing the filter’s performance. Water that sits unused may change chemistry slightly. Adjusting configuration of water treatment may be helpful to ensure consistent reduction of detected heavy metals over time.
If you want to know how treated water differs with a heavy metals filter
Using a product like the Fleck Heavy Metals Filter alters tap water by reducing dissolved heavy metals including selenium. This system uses specialized filtration media and technology designed to lower concentrations from groundwater before it reaches household plumbing. Households can expect reduced heavy metals content that matches the filter’s documented performance specifications. Since these filters ship ready to configure, households can integrate them into their water systems without professional setup.
If you plan to seek advice or further treatment options
Before consulting anyone about heavy metals treatment, record your water source type, well depth if applicable, recent water quality tests, and any observed water issues such as color, taste, or staining. Having this information ensures more accurate recommendations tailored to your home's needs and water conditions.
If you note symptoms like health concerns or fixture corrosion
While heavy metals presence can influence some health factors over long-term exposure, government sampling here shows no federal standard exceedances. Corrosion or sudden water quality changes can be caused by plumbing materials or other water chemistry issues unrelated to selenium counts. Documenting symptoms precisely helps distinguish what testing and treatment steps are appropriate.
To finalize whether your household water needs targeted heavy metals treatment, order a comprehensive water test measuring selenium and other metals directly from your tap or well source. A result showing concentrations above health-based limits would confirm need for treatment such as the Fleck Heavy Metals Filter. If below limits, ongoing monitoring or less intensive treatment might suit.
Where this information comes from
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 Selenium in the 112CHCTU aquifer (Lafayette Parish): 56 results from 31 wells, median 0.37 ug/L, range 0.03-5.6 ug/L; none above any federal threshold
