Overview of Water from the 120FLRD Aquifer in Beaufort County
Water supplied to homes in Beaufort County often originates from the 120FLRD aquifer, a deep groundwater source typically accessed at depths between 100 and 210 feet. Water from this aquifer travels through underground rock layers before reaching residential taps. This natural journey influences the taste, hardness, and mineral content characteristic of local water, including the presence of iron.
Consequences of Untreated Iron and Hardness Over Time
Iron accumulation causes staining on fixtures and laundry
Iron in water can leave reddish-brown stains on sinks, tubs, and clothing when not addressed.
Hardness contributes to mineral buildup inside pipes and appliances
Water hardness from calcium and magnesium compounds can lead to scale deposits, reducing the efficiency and lifespan of water heaters and appliances.
Possible subtle impacts on water taste and clarity
While not a health concern, iron and hardness may affect water appearance and flavor in ways some users notice.
Steps to Diagnose Iron and Hardness Issues Efficiently
Begin with visual inspection of stains and water characteristics
Look for signs like reddish staining and mineral deposits around plumbing fixtures.
Perform household water hardness testing kits
These kits provide a preliminary measure of water hardness levels.
Obtain comprehensive laboratory analysis for iron concentration
Professional testing of your own well or water source is needed to identify exact iron levels.
Compare results with area aquifer data as an initial reference
U.S. Geological Survey groundwater samples from Beaufort County’s 120FLRD aquifer found iron detected in some wells with a median of 416 micrograms per liter (µg/L), but none exceeding federal limits.
Understanding Plumbing Material and Age Effects Separately
Older pipes may exacerbate visible staining
Corrosion or wear in older plumbing can increase the appearance of iron-related stains.
Material type does not alter source water iron levels
The iron content originates from groundwater, independent of plumbing materials.
Pipe scale can trap iron and minerals temporarily
Scale buildup may hold iron deposits that periodically wash loose, influencing water appearance.
How Iron Enters Groundwater in Beaufort County
Natural soil and rock mineral dissolution
Iron is naturally present in minerals that dissolve slowly into groundwater over time.
Depth and aquifer composition influence iron presence
The 120FLRD aquifer’s geology affects iron levels detected in area wells sampled between 2011 and 2018.
Interpretation of Measured Iron Ranges Versus Federal Guidelines
Range in samples: 19.6 to 436 micrograms per liter
This range reflects variability among wells in the aquifer but is not a measurement of any one household well.
No sample exceeded federal iron thresholds
Although iron is detected, all results are within regulatory allowances, indicating no federal violation.
Detection does not indicate water is unsafe
Detecting iron alone does not mean health risks are present; iron commonly affects water aesthetics and function.
What Not to Conclude from Area Sampling Data
Government aquifer sampling data provide a regional perspective and are not specific to an individual household’s well or water quality. Therefore, these data do not identify the exact iron or hardness levels in your home’s water. Testing your own water source is essential for precise understanding and appropriate treatment.
For households managing iron and hardness challenges, the Autotrol Iron + Hard Water (Well) System ships ready to configure and offers a documented solution designed for capacity up to 32,000 grains. This system is engineered to reduce iron and hardness effects, improving water quality throughout the home.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2018-08-07. 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 120FLRD aquifer (Beaufort County): 6 results from 5 wells, median 416.0 ug/L, range 19.6-436.0 ug/L; none above any federal threshold
