What Does the Sampling Record in Lyon County Tell Us About Iron Bacteria?
The U.S. Geological Survey conducted groundwater sampling in Lyon County's aquifer 110VLFL from 2010 to 2014. They sampled six separate wells between 60 and 196 feet deep, with 22 total results for iron. Iron was detected in 20 samples, with a median concentration of 15.8 micrograms per liter and values ranging from 4.4 up to 1600 micrograms per liter. Two samples were below the reporting limit. Importantly, none of these results exceeded any federal threshold for iron or iron-related contaminants. This data reflects the conditions of these specific wells in the area but does not indicate iron levels in any individual household well or tap.
What Do 'Detected', 'Median', and 'Range' Indicate in This Groundwater Sampling?
A detection means iron was measurable in a sample but does not imply a health or safety violation. The median is the middle value of the measured concentrations, giving a central tendency among the samples. The range shows the lowest and highest iron measurements recorded within these wells. Since these wells represent a small number of samples, the data can give a general idea of iron presence in this aquifer but does not predict exact iron levels for any single water source in Lyon County. Personal testing is necessary to know individual water quality.
How Does Water Change When Treated With an Autotrol Iron Bacteria & Slime Filter?
The Autotrol Iron Bacteria & Slime Filter is designed to address iron bacteria and the slime they produce in residential water systems. When configured, it reduces iron bacteria presence and helps control slime buildup that can cause staining, plumbing blockages, or unpleasant water appearance. Treated water at the tap generally shows clearer flow and fewer iron bacteria-related deposits. This technology works without changing reported iron concentrations directly but instead targets the biological component causing common household issues linked to iron bacteria.
Which Household Symptoms Suggest Iron Bacteria and Which Do Not?
Iron bacteria often produce slimy residues, reddish or brown staining on fixtures, and can cause a metallic taste or foul appearance in water. Persistent clogging of pipes or filters may also be related. However, not all stains or taste issues originate from iron bacteria; other minerals or plumbing materials can cause similar effects. Presence of these symptoms alone does not confirm iron bacteria without proper testing for bacterial slime. Combining symptom observation with water analysis helps clarify if iron bacteria is the source.
How Do Well Depth and Sample Depth Affect What to Expect About Iron Bacteria?
Groundwater samples were taken from wells ranging 60 to 196 feet in depth. Iron bacteria levels can vary with depth due to changing geochemical conditions and oxygen exposure. Shallower wells might show different patterns than deeper ones. This variation means the iron bacteria presence in one well may not match another well even nearby. The sample depth and well construction type influence biofilm growth potential. Residents should consider their specific well characteristics alongside area-wide data to understand potential iron bacteria impacts.
Summary: This page reviewed Lyon County aquifer sampling data and explained what detects of iron represent. It examined water symptoms linked to iron bacteria and clarified the role of well and sample depth in expectations. Finally, it described how an Autotrol Iron Bacteria & Slime Filter can help address iron bacteria issues in residential water.
