Government sampling in Cleveland County's aquifer 318GRBR shows iron detected in groundwater at concentrations ranging from 3.3 to 85.2 micrograms per liter across 41 samples taken from six separate wells between May 2012 and May 2013. The median iron level was 12.5 micrograms per liter. None of these measurements exceed federal thresholds. These data describe the regional groundwater quality but do not define individual well water conditions.
If you operate a commercial or industrial water system in addition to household usage
Your considerations expand beyond residential treatment. Commercial or industrial operators often need to balance higher volumes and varying water quality demands. You might face stricter regulatory oversight or require equipment that handles fluctuating conditions. This page focuses on residential demand, but if your use exceeds typical household volumes, equipment with higher capacity or specialized features may be necessary.
If your area’s water quality varies seasonally or over several years
The USGS data collected samples over a one-year period from mid-2012 to mid-2013. Results showed iron presence in about two-thirds of the samples, with values spanning a broad range. This indicates potential fluctuations in groundwater composition over time or differences between wells. Long-term monitoring would be needed to establish if seasonal shifts affect metallic taste in your water.
If you want to rule out causes of metallic taste starting from the simplest checks
Start by ensuring plumbing fixtures and faucets are not contributing to taste changes. Corrosion or metal buildup inside household piping can cause metallic flavors. If these are not the source, the next step is a certified laboratory water test from your own well or supply to determine current iron levels and other possible contributors. Regional data provide context but your own test is essential for precise diagnosis.
If you compare the Cleveland County aquifer iron results to what they might mean for you
The median iron concentration of 12.5 micrograms per liter is low relative to established federal secondary standards that guide aesthetic concerns like taste and staining. The highest detected value, 85.2 micrograms per liter, remains below thresholds associated with significant taste issues. However, even low iron at certain water chemistry conditions can create metallic taste sensations. Testing your house water is necessary to know your actual concentration.
If you want to distinguish metallic taste from other common water issues
Metallic taste is often confused with earthy or musty flavors caused by organic compounds, or with strong chlorine or other disinfectant tastes in treated water. It differs from sulfur-related odors or vinegar-like sourness. Iron presence is a frequent cause of metallic taste. Confirming iron as the cause requires testing and consideration of your water’s specific chemistry.
For households identifying metallic taste linked to measured iron levels consistent with those found in Cleveland County aquifer 318GRBR, the Fleck Metallic-Tasting Water Filter provides a documented solution. This system ships ready to configure and addresses the demand established by your water testing, improving taste by reducing iron and associated metallic flavor contributors.
