Understanding the Sample Size and Scope Behind Ouachita Parish Iron Data
Multiple Wells and Years Inform These Figures
The U.S. Geological Survey collected 24 iron sample results from seven different wells within Ouachita Parish's aquifer 124SPRT between March 2010 and December 2014. These wells ranged in depth from 340 to 730 feet. This dataset represents a regional snapshot, not the condition of any individual household well.
Small Sample Size Limits Individual Prediction
While the sampling covers various wells and years, it is a small number of points relative to the entire aquifer area. This means the data provide a median and range that help understand general trends but cannot indicate a specific well’s iron concentration without direct testing.
Interpreting Certified Laboratory Iron Tests
Laboratory Reports Show Concentration in Micrograms per Liter
A certified lab test for iron reports the concentration in micrograms per liter (ug/L), a precise measure of dissolved iron. The regional median iron concentration is 21.8 ug/L, with a range from 4.8 to 142.0 ug/L among the sampled wells.
Detection Does Not Equate to a Safety Concern
All sampled results showed detectable iron levels, but none exceeded any federal safety threshold. Detecting iron simply means it is present, not that it is unsafe or out of compliance. Iron primarily affects water aesthetics like taste, staining, and color rather than health.
Differences Between Public Water Records and Private Well Tests
Public System Records Reflect Treated Water Quality
Public water system records report water quality after treatment and distribution, often showing lower iron levels due to regulation and treatment processes.
Private Well Sampling Reflects Untreated Source Water
By contrast, government sampling of wells in Ouachita Parish directly measures the untreated aquifer water, providing raw source data that the household may experience if untreated.
Placing the Detected Iron Range in Context of Federal Standards
Federal Thresholds Are Not Exceeded in the Area Sampling
The range of 4.8 to 142.0 ug/L iron concentrations detected in aquifer 124SPRT wells is below any federal health-based standard. Therefore, this iron presence is not a regulatory violation but may affect water taste and cause staining.
Iron Levels Affect Household Water Use
Iron contributes to hardness-related issues such as mineral buildup on fixtures and inside appliances, which can affect their performance and longevity.
How the Pentair Iron + Hard Water System Addresses These Issues
Removes Iron and Softens Hardness with 32,000 Grain Capacity
This system is designed to reduce iron and hardness in household water, helping prevent discoloration, stains, and mineral deposits. It ships ready to configure for residential use and offers a grain capacity of 32,000, suitable for many household demands.
Technology Targets Both Dissolved Iron and Hardness
The Pentair system uses processes that effectively remove dissolved iron particles and soften water to improve water quality and protect plumbing and appliances over time.
Closing Summary
The government data from multiple wells sampled between 2010 and 2014 provide regional iron concentrations in Ouachita Parish’s aquifer 124SPRT that do not exceed federal health-based limits but indicate iron presence that can impact water quality. A certified laboratory test of your own water is essential to know your household’s specific conditions. The Pentair Iron + Hard Water System is a documented solution designed to reduce iron and hardness, improving residential water usability.
