Seasonal and Multi-Year Variation in Manganese Concentrations
The U.S. Geological Survey collected groundwater samples from seven wells in the 100SDGV aquifer within Dane County during May 23-24, 2022. These measurements provide a snapshot of manganese concentrations over a short timeframe and across multiple wells. The data shows manganese consistently detected in all 20 samples, with values ranging from 100.0 mg/kg to 3600.0 mg/kg. Because this sampling occurred within two days, it does not reflect seasonal fluctuations but offers insight into short-term spatial variation within the aquifer.
Understanding the Median and Range as a Dane County Homeowner
The median manganese value from these samples was 595.0 mg/kg. This median represents the middle value of the collected data from the sampled wells, not the concentration in any specific household's water. The wide range, from 100.0 to 3600.0 mg/kg, indicates that manganese concentrations can vary significantly across locations in the same aquifer. Homeowners should test their own water to determine the exact manganese level for their household.
Distinguishing Manganese from Commonly Confused Water Constituents
Manganese is often mistaken for iron due to similar staining and discoloration problems it can cause in household water. Unlike iron, manganese can leave darker, blackish stains on fixtures and laundry. Manganese also can affect taste and color but differs in chemical behavior and treatment needs. This distinction matters when selecting treatment equipment because the technologies effective for iron do not always work well for manganese.
Maintenance Rhythm for the Autotrol Black Manganese Stains Filter
The Autotrol Black Manganese Stains Filter ships ready to configure and uses an automated system designed to handle manganese removal for residential water supplies. Maintenance typically involves checking the system's media condition annually and performing backwashing cycles to prevent accumulation of manganese deposits. Users should follow the manufacturer's guidelines for media replacement intervals based on their water usage and manganese concentration measurements.
Reading a Certified Laboratory Test Report for Manganese
A certified lab test report for manganese in water lists the concentration as milligrams per kilogram or micrograms per liter, reflecting the amount of manganese dissolved or suspended in the water. The report will show the exact result for the tested sample but does not by itself indicate a violation or health risk. Interpreting the report requires comparing the number to consumer taste and staining guidelines, and possibly consulting treatment options if manganese is detected at levels that affect household use.
For homeowners in Dane County measuring manganese in their water supply, the Autotrol Black Manganese Stains Filter offers a documented solution designed to meet residential demand based on the manganese levels detected. Selecting this equipment can address common issues like staining and taste, helping maintain water quality aligned with your household’s specific test results.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2022-05-24. 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 100SDGV aquifer (Dane County): 20 results from 7 wells, median 595.0 mg/kg, range 100.0-3600.0 mg/kg; none above any federal threshold
