Interpreting Manganese Data from Shelby County's Aquifer 100ALVM
Water supplied to homes in Shelby County commonly originates from groundwater sources such as aquifer 100ALVM. Federal sampling by the U.S. Geological Survey between September 20 and 28, 2017 collected ten manganese measurements from five wells in this aquifer, at depths ranging 55 to 166 feet. The median manganese concentration recorded was 367.0 micrograms per liter (ug/L), with a range from 302.0 to 1300.0 ug/L. All results indicated manganese was detected; none fell below reporting limits.
For a household evaluating these numbers, it is important to recognize these are area-wide samples from several wells, not specific to any individual well or tap. Testing your own water supply is necessary to determine your manganese concentration precisely. This data provides a context for what may be typical in this aquifer but does not specify your home's water quality.
How Autotrol Technology Addresses Manganese in Household Water
The Autotrol Black Manganese Stains Filter is designed to reduce manganese concentrations that can cause staining, discoloration, and potential taste issues in residential water. The Autotrol System employs filtration media that reacts with dissolved manganese, removing it before water reaches taps. This process can also help mitigate secondary aesthetic concerns such as staining on fixtures and laundry.
This equipment ships ready to configure and connects within existing water lines without additional professional involvement. It offers a proven approach to managing manganese at levels typical of the Shelby County aquifer samples.
Differences Between Public Aquifer Sampling and Private Well Testing
Government samples from multiple wells in an area provide valuable regional data on manganese trends and ranges but do not replace individual water testing. Private wells can vary significantly based on depth, location, and local geology. Sampling several nearby wells helps identify general manganese presence in the aquifer but cannot predict your water specifically.
To understand the manganese concentration in your household water, conducting a specific well or tap test is necessary. Such testing will confirm manganese levels and guide treatment decisions based on your unique water profile.
What the Sampling Range Means Relative to Federal Guidelines
None of the manganese measurements from the Shelby County aquifer samples exceeded federal health-based thresholds. Manganese is monitored for both health and aesthetic effects, but the federal secondary standards primarily address taste and staining concerns. The detected range, from 302 to 1300 ug/L, is below regulatory action levels specified for public water systems.
This means that while manganese is present and at various detected concentrations, none of these results signify a violation or unsafe condition under federal guidelines. However, aesthetic issues such as discoloration or staining can still occur at these levels.
Additional Considerations for Non-Residential Water Users
Commercial and industrial operators may face different requirements regarding manganese due to larger water volumes, equipment sensitivity, or regulatory permits. These users often conduct more frequent and detailed testing to meet operational standards and avoid equipment fouling or process disruption.
Households generally focus on visible symptoms and water quality tests relevant to health and comfort. Industrial evaluation methods may include continuous monitoring and chemical analyses beyond residential testing scope.
Summary: This briefing reviewed manganese concentrations in Shelby County's aquifer 100ALVM, highlighting the range and median from government samples. It explained how the Autotrol Black Manganese Stains Filter technology effectively reduces manganese-related issues. Differentiating area-wide sampling from private well testing clarifies what homeowners should do to assess their water. The government data showed no federal threshold exceedances but does confirm manganese presence that may impact aesthetics and comfort.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2017-09-28. 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.
