Understanding Manganese Measurements in Cumberland County's 112OTSH Aquifer

The 112OTSH aquifer in Cumberland County, Maine, supplies groundwater to many residences. According to the U.S. Geological Survey, four samples from a well in this aquifer collected between June 2015 and May 2016 showed manganese levels detected consistently, with a median concentration of 15.0 micrograms per liter (ug/L) and a range from 10.0 to 40.0 ug/L. These values were all below any federally established threshold for health-based or secondary standards. It is important to note that these measurements represent regional data from sampled wells 22 feet deep and do not specify the manganese level in any single household’s water supply. Testing of your own water source is necessary to understand its manganese concentration accurately.

Which Household Areas Are Most Impacted by Manganese Presence?

Manganese in water can cause particular issues with certain fixtures and appliances. Typically, it affects areas with frequent water contact, such as:

• Faucets and showerheads, where staining or discoloration may appear on visible surfaces
• Washing machines, where manganese deposits might affect clothes' appearance if not addressed
• Water heaters, which may accumulate manganese deposits over time, potentially impacting efficiency

Areas with slower or standing water flow, such as toilet tanks or rarely used taps, may also show manganese buildup. Understanding which fixtures show signs of manganese presence can help focus investigation and treatment decisions.

Steps to Confirm Manganese Impact in Your Household Water

Before selecting a treatment approach, it is advisable to follow a series of checks:

• Begin with an inspection of visible staining or discoloration on plumbing fixtures and laundry, as manganese can cause brown or black stains
• Review any recent changes in water taste or appearance, although these can be subjective
• Obtain a water sample analyzed by a certified laboratory to determine your home’s specific manganese concentration and related water quality parameters
• Eliminate other potential sources of staining or discoloration, such as iron or other minerals, to confirm manganese as the issue

These steps help establish whether treatment is needed and inform the capacity required for an effective solution.

Recognizing Symptoms That Align or Do Not Align With Manganese Issues

Some household signs align closely with manganese presence, while others suggest different concerns:

• Common manganese-associated symptoms: brown or black staining on sinks, bathtubs, laundry, or toilets; deposits forming in water heaters; water appearing dark or discolored after standing
• Symptoms unlikely caused by manganese: unusual odors, persistent cloudy water, taste resembling chlorine or sulfur, or corrosion damage directly linked to low pH

Accurate symptom assessment helps narrow down water quality issues and direct appropriate testing.

Seasonal and Multi-Year Variation in Manganese Levels in Cumberland County

The available data spans nearly one year from June 2015 to May 2016, showing manganese detected consistently throughout this period. Concentrations varied between 10.0 and 40.0 ug/L but remained below health-based thresholds. This pattern suggests that manganese occurs steadily in this aquifer rather than in sporadic spikes. Residents should be aware that natural fluctuations in groundwater chemistry can occur seasonally or over multiple years. However, the current local data does not point to sudden or severe changes in manganese concentration over the sampled timeframe.

Understanding these regional trends provides context but emphasizes that individual well monitoring is necessary to detect personalized changes and decide on treatment.

In summary, manganese is regularly present in Cumberland County’s 112OTSH aquifer at levels documented by government samples but below health-based limits. Homeowners seeking to address manganese-related water concerns should first confirm their well’s manganese concentration through testing and consider visible signs in household fixtures. For treatment, the Fleck Black Manganese Stains Filter is designed to target manganese removal effectively and ships ready to configure for residential use. This page has guided you through interpreting local sampling data, identifying manganese impacts, and choosing appropriate next steps toward clearer water.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2016-05-25. 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 112OTSH aquifer (Cumberland County): 4 results from 1 wells, median 15.0 ug/L, range 10.0-40.0 ug/L; none above any federal threshold
