Deeper Wells Mean Different Manganese Expectations
Many homeowners in Calcasieu Parish expect their home's manganese levels to match surface water or shallow well reports, but the groundwater sampled here comes from depths of 480 to 651 feet within aquifer 11205LC. This depth influences the manganese levels encountered, which can be higher or lower compared to shallow sources due to natural geological factors. Understanding this is important after your treatment equipment has failed, as it impacts what any replacement system must handle.
How the Median and Range Help Homeowners Understand Local Manganese Levels
Sampling conducted by the U.S. Geological Survey in Calcasieu Parish found manganese concentrations ranging from 204 to 434 micrograms per liter, with a median of 364 micrograms per liter across 13 samples from six wells. These figures represent typical local conditions at depth but do not predict the exact manganese level in any individual well. They serve as a guide for what to expect and how treatment systems should be chosen.
What 'Detected,' 'Median,' and 'Range' Clarify About Manganese Sampling Results
In this data set, manganese was detected in every sample, which means the measuring equipment found the element present in all tested wells. The median indicates the middle value across all samples, offering a typical concentration estimate, while the range shows the highest and lowest values observed. None of these readings exceeded federal limits, so detections indicate presence but not a violation or health risk by themselves.
Why Private Well Testing Differs From Public System Records for Manganese
Public system records like those from the U.S. Geological Survey rely on periodic sampling of multiple wells to establish a regional picture. Private well conditions may vary due to local geology, well depth, and other factors, so individual water quality can differ. Since your equipment has failed, testing your well water specifically is critical to confirm the manganese levels that need treatment in your household.
How Multi-Year Sampling Reveals Manganese Consistency and Variation
The samples in Calcasieu Parish were collected over a seven-year period from 2010 to 2017. Consistent manganese detection across this time frame suggests stable presence in the aquifer, although actual concentrations may vary seasonally or between wells. This stability helps in selecting appropriate treatment solutions that can handle the expected manganese concentration range reliably.
How the Pentair Black Manganese Stains Filter Addresses Manganese in Household Water
The Pentair Black Manganese Stains Filter is designed to reduce manganese in residential water supplies, helping to prevent staining and other aesthetic issues that manganese can cause. After equipment failure, this system ships ready to configure and works by filtering manganese effectively, supporting households in Calcasieu Parish in maintaining water quality consistent with local groundwater characteristics.
Next Step: To determine the exact manganese concentration in your household water and confirm the need for treatment, arrange for a professional water test focused on manganese levels in your specific well. This result will guide selecting the best solution and restoring water quality after your previous equipment stopped functioning.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2017-04-20. 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 Manganese in the 11205LC aquifer (Calcasieu Parish): 13 results from 6 wells, median 364.0 ug/L, range 204.0-434.0 ug/L; none above any federal threshold
