Water in Orangeburg County, SC, frequently comes from wells tapping into the 111SANDD aquifer. This underground water source provides groundwater accessed by residential wells, where water travels through soil and rock layers before reaching taps. Treatment choices often depend on understanding water quality conditions established over time in these aquifers.
Belief: Iron bacteria levels in our area are constant year-round
The US Geological Survey sampled seven different wells in Orangeburg County's 111SANDD aquifer between November 2011 and November 2018, collecting eight iron concentration results. Iron was detected in half of these samples, with measurements ranging from 10.9 to 123.0 micrograms per liter and a median value of 51.75 micrograms per liter. This data shows natural variation in iron presence over multiple years and locations, not a fixed or unchanging condition. Seasonal or environmental factors can influence these readings, contributing to fluctuations rather than a steady state.
Belief: Treatment equipment removes iron bacteria by filtering or neutralizing it
The C-Series Iron Bacteria & Slime Filter system is designed specifically to address iron bacteria and slime deposits found in groundwater supplies like those in Orangeburg County. This technology functions by physically filtering out iron bacteria and associated slime, improving water clarity and reducing biofilm buildup. While it does not change water chemistry at the molecular level, it effectively traps and removes these organisms and their residues to protect household plumbing and appliances.
Belief: Public system water records directly represent private well water quality
Public water system records provide data about regulated municipal supplies but do not necessarily reflect the conditions present in private residential wells. The USGS sampling data from 111SANDD aquifer wells represents a broad area aquifer profile, not individual wells. Private well owners should perform their own water tests to confirm their specific water chemistry and iron bacteria presence before selecting treatment equipment.
Belief: Household size or seasonal use does not influence water treatment needs
Larger households or homes used seasonally can experience different water quality dynamics, including iron bacteria growth. Periods of inactivity can allow slime and biofilm to accumulate in plumbing, whereas high water demand in large households may require systems capable of higher flow rates and more frequent maintenance. Choosing equipment like the C-Series system should account for these usage patterns to ensure effective and sustained treatment.
Belief: Untreated iron bacteria causes immediate health risks or system failures
Iron bacteria are not a health hazard as defined by federal standards, and no sample taken from the 111SANDD aquifer wells exceeded any health-based limits. However, untreated iron bacteria can lead to staining of fixtures, slime deposits, and clogging in plumbing systems over time. These impacts tend to develop gradually and can complicate household maintenance and appliance longevity but do not represent acute safety concerns.
Belief: Sample depth or well depth strongly determines iron bacteria levels
The wells sampled were comparatively shallow, between 12 and 24 feet deep, reflecting conditions near the land surface. Deeper wells might show different iron bacteria profiles, but data for such depths is not available for this area. Users should consider that bacterial presence and iron concentrations can vary with well depth, construction, and local hydrogeology, making it essential to test their own well water for an accurate assessment.
Understanding the USGS iron data for Orangeburg County’s aquifer 111SANDD and its limitations helps households decide among treatment options. Testing individual well water remains critical. Where iron bacteria are confirmed, the C-Series Iron Bacteria & Slime Filter offers a ready-to-configure solution to manage bacteria and slime, suited for varying household sizes and usage patterns.

On record: U.S. Geological Survey sampling of Iron in the 111SANDD aquifer (Orangeburg County): 8 results from 7 wells, median 51.75 ug/L, range 10.9-123.0 ug/L; none above any federal threshold
