A laboratory report for iron in Jefferson County's aquifer 371CCCGG, based on U.S. Geological Survey groundwater sampling from 2013 to 2024 across seven wells, shows measurements ranging from 5.0 to 6.3 micrograms per liter (ug/L) and a median of 5.9 ug/L. Iron was detected in three of the ten samples, with the rest below the reporting limit. No sample exceeded any federal threshold or health-based limit. These results reflect regional aquifer conditions and not your household well specifically.
If You Note Variation Over Months or Years
The sampling dates span over a decade, demonstrating limited fluctuation in iron concentrations in the aquifer. Seasonal or yearly changes may occur, but the record suggests fairly stable iron presence in this deep groundwater zone (155 to 445 feet). This stability helps in anticipating potential iron bacteria activity but does not guarantee identical conditions in any single well. Ongoing testing of your own source water remains essential to understand your household’s specific iron levels and bacterial presence.
If You Consider How Treatment Addresses Iron Bacteria
The presence of iron in water can encourage growth of iron bacteria, which form slimy deposits and can clog pipes and fixtures. The Autotrol Iron Bacteria & Slime Filter is designed to address this by filtering bacteria colonies and iron particles effectively, helping reduce slime buildup and related issues. This system ships ready to configure and can be selected based on the iron concentration measured in your household water rather than regional averages.
If Plumbing Materials and Age Are a Concern
Besides source water iron, household plumbing materials and system age can influence slime development. Older iron or galvanized pipes may harbor bacteria more readily, aggravating slime even if source water iron is low. Copper or plastic plumbing might reduce bacteria growth opportunities. Considering your home’s plumbing type helps determine whether treatment focused solely on source water iron bacteria is sufficient or if additional maintenance measures are warranted.
If You Compare Public System Data with Private Well Testing
Area-wide public data, such as this Jefferson County aquifer sampling, give a general overview but do not substitute for private well testing. Public systems often monitor at points serving many users, while private wells reflect localized conditions influenced by well depth, construction, and surrounding geology. A private test that measures iron and bacterial presence directly will better guide the selection of an appropriate treatment system for your household needs.
If You Need to Interpret 'Detected', 'Median', and 'Range'
'Detected' means iron levels were measurable above the reporting limit; it does not indicate a violation or unsafe condition. The median of 5.9 ug/L represents the midpoint concentration in all samples, with a range from 5.0 to 6.3 ug/L showing the spread of measurements in this area. These figures inform the background iron occurrence but do not define your specific water quality, which requires direct testing.
When choosing treatment for iron bacteria in your household water, base decisions on your own water quality results rather than solely on Jefferson County aquifer data. The Autotrol Iron Bacteria & Slime Filter offers a documented solution effective against iron bacteria-related slime and can be selected according to your measured iron and bacterial levels for tailored water improvement.
